Abstract:
Biofouling is a major problem shared among all maritime sectors employing submerged structures where it leads to substantially increased costs and lowered operational lifespans if poorly addressed. Insight into the ongoing processes at the relevant marine locations is key to effective management of biofouling. Of specific concern for the marine renewable energy (MRE) sector is the fact that information on biofouling composition and magnitude across geographies is dispersed throughout published papers and consulting reports. To enable rapid access to relevant key biofouling events the present work describes a European biofouling database to support the MRE sector and other maritime industries. The database compiles in one document qualitative and quantitative data for challenging biofouling groups, including non-native species associated with MRE and related marine equipment, in different European Ecoregions. It provides information on the occurrence of fouling species and data on key biofouling parameters, such as biofouling thickness and weight. The database aims to aid the MRE sector and offshore industries in understanding which biofouling communities their devices are more susceptible to at a given site, to facilitate informed decisions. In addition, the biofouling mapping is useful for the development of biosecurity risk management plans as well as academic research.

Abstract:
MRE provides great potential for Malaysia, an emerging economy, to diversify its primary energy mix and ensuring the security of its energy supply. In this paper, the state-of-the-art of each MRE type is studied alongside hydrographical and geographical conditions of Malaysian waters. It is based upon this knowledge that an MRE scheme is proposed for Malaysia. However, introducing a complex MRE system into Malaysia’s energy pool requires in-depth understanding of key governing factors and the dynamic behaviours of its implementation using a systemic approach. Results from system dynamics modelling have identified key-enablers to fast-track the implementation of MRE in Malaysia.

AbstractThe Chinese government has attached great significance to the research, development, and utilization of marine renewable energy (MRE), all of which made significant achievements in the year 2012. This paper systematically reviews and analyzes the development status of China's MRE industry, in terms of resources, policies, and technologies. Some problems are also pointed out, in order to provide further suggestions for China's MRE sector in the future. Prospects and main tasks in the near future are proposed to establish the demonstration bases of MRE and the national public supporting platform for MRE. The development and utilization of MRE have become a significant measure for China for increasing renewable energy power, optimizing energy structure, developing the marine economy, and reducing power shortages on islands. In the future, China will continue to promote the R&D of ocean energy technology as well as the development of technology demonstration and perfection among service providers of industrial applications.

Abstract:
Marine renewable energy (MRE) is under development in many coastal nations, adding to the portfolio of low carbon energy sources that power national electricity grids as well as off-grid uses in isolated areas and at sea. Progress in establishing the MRE industry, largely wave and tidal energy, has been slowed in part due to uncertainty about environmental risks of these devices, including harm to marine animals and habitats, and the associated concerns of regulators and stakeholders. A process for risk retirement was developed to organize and apply knowledge in a strategic manner that considered whether specific environmental effects are likely to cause harm. The risk retirement process was tested against two key MRE stressors: effects of underwater noise from operational MRE devices on marine animals, and effects of electromagnetic fields from MRE electrical export cables on marine animals. The effects of installation of MRE devices were not accounted for in this analysis. Applying the risk retirement process could decrease the need for costly investigations of each potential effect at every new MRE project site and help move the industry beyond current barriers.

Abstract:
Marine renewable energy (MRE) harnesses energy from the ocean and provides a low-carbon sustainable energy source for national grids and remote uses. The international MRE industry is in the early stages of development, focused largely on tidal and riverine turbines, and wave energy converters (WECs), to harness energy from tides, rivers, and waves, respectively. Although MRE supports climate change mitigation, there are concerns that MRE devices and systems could affect portions of the marine and river environments. The greatest concern for tidal and river turbines is the potential for animals to be injured or killed by collision with rotating blades. Other risks associated with MRE device operation include the potential for turbines and WECs to cause disruption from underwater noise emissions, generation of electromagnetic fields, changes in benthic and pelagic habitats, changes in oceanographic processes, and entanglement of large marine animals. The accumulated knowledge of interactions of MRE devices with animals and habitats to date is summarized here, along with a discussion of preferred management methods for encouraging MRE development in an environmentally responsible manner. As there are few devices in the water, understanding is gained largely from examining one to three MRE devices. This information indicates that there will be no significant effects on marine animals and habitats due to underwater noise from MRE devices or emissions of electromagnetic fields from cables, nor changes in benthic and pelagic habitats, or oceanographic systems. Ongoing research to understand potential collision risk of animals with turbine blades still shows significant uncertainty. There has been no significant field research undertaken on entanglement of large animals with mooring lines and cables associated with MRE devices.

Energy production based on fossil fuels is the main reason for global warming. Many countries have begun switching fossil fuels with renewable energies, reducing the effects of climate change. A tremendous potential in future energy needs plays the Marine Renewable Energies (MRE). The MRE industry should take into consideration the potential environmental effects and if it poses any risks to marine animals, surrounding habitats or ecosystem processes. This research provides some insights regarding the MRE development and points out the potential environmental effects of implementing them and finally, draws some lines regarding the ecological effects of the MRE extraction from the Black Sea.

Abstract:
ABSTRACT Brazil has great potential for the development of technologies for the conversion of marine energy from waves and tides, which raises the discussion about the possible environmental impacts of these projects. This article seeks to synthesize knowledge about the risks of collision of marine animals, such as mammals, fish and birds, with marine renewable energy (MRE) devices, as well as to identify priority species for environmental monitoring along the Brazilian coast. The risk of marine mammals colliding with MRE devices is influenced by regional and behavioral factors. The risk of collision in a fish community is influenced by the avoidance behavior, the distribution of fish in the MRE sites and the stages of the enterprise (installation, operation and maintenance). Seabird collision risk is influenced by species behavior (geographical distribution, seasonal habitat use, diving time and depth) and the location of MRE structures (surface and/or water column). The survey of priority species for monitoring the risk of collision with MRE devices in Brazil consisted of 5 species of marine mammals, 13 taxa of seabirds, 5 species of endangered sea turtles and 18 species or groups of species of fish of economic importance to the country. The research review did not record the occurrence of collisions with marine animals. However, this does not mean that they did not occur, but that they may not have been observed due to monitoring challenges. The study concluded that research on the interaction of marine animals with MRE devices should be encouraged, even in prototypes and non-commercial projects, in order to reduce knowledge gaps and support the development of MRE in an environmentally sound manner.

Abstract:
Marine renewable energy (MRE) is still an emerging technology. As such, there is still a lack of mature standards and guidance for the development and testing of these devices. The sector covers a wide range of disciplines, so there is a need for more comprehensive guidance to cover these. This paper builds on a study undertaken in the MaRINET2 project to summarise recommendations and guidance for testing MRE devices and components, by reviewing the recently published guidance. Perceived gaps in the guidance are then discussed, expanding on the previous study. Results from an industry survey are also used to help quantify and validate these gaps. The main themes identified can be summarised as: the development progression from concept to commercialisation, including more complex environmental conditions in testing, accurately modelling and quantifying the power generated, including grid integration, plus modelling and testing of novel moorings and foundation solutions. A pathway to a standardised approach to MRE testing is presented, building on recommendations learnt from the MaRINET2 round-robin testing, showing how these recommendations are being incorporated into the guidance and ultimately feeding into the development of international standards for the marine renewable energy sector.

Abstract:
AbstractMarine renewable energy (MRE) encompasses the harvest of energy from the movement of ocean waters in the form of either currents or waves, as well as temperature and salinity differentials. To date, most MRE development has focused on utility-scale electrical grid generation, but a growing body of work focuses on non-grid applications in the blue economy where MRE could provide power on-site and at the scale needed for specific maritime sectors. One of the blue economy sectors with promising applications for MRE is ocean observations using both mobile and stationary platforms. This paper documents the steps and results of engaging with experts across the myriad ocean observation platforms and capabilities to inform five use cases. These use cases include descriptions of specific ocean observation applications performing measurements of high societal value (e.g., data for weather forecasting and tsunami detection) that closely resemble specific sensing systems and, in most cases, are placed in a particular area of the ocean. Rapid resource assessments (i.e., first-order estimates) were performed at these locations to determine the suitability of marine and other renewable energy sources. From the information gathered so far, MRE has significant potential to enable improved ocean observation missions, expand ocean observing capacity, and develop as an industry in parallel with the needs of our changing oceans.

Abstract:
Abstract Marine renewable energy (MRE) is an emerging source of power for marine applications, marine devices, and coastal communities. This energy source relies on industrial control systems and IT to support operations and maintenance activities, which create a pathway for an adversary to gain unauthorized access to systems and data and disrupt operations. Incorporating cybersecurity risk prevention measures and mitigation capabilities from inception, development, operation, to decommissioning of the MRE system and components is paramount to the protection of energy generation and the security of network architecture and infrastructure. To improve the resilience of MRE systems as a predictable, affordable, and reliable source of energy, cybersecurity guidance was developed to enable operators to assess cybersecurity risks and implement security measures commensurate with the risk. This publication is the second of a two-part series, with Part 1 addressing a framework to determine cybersecurity risk by assessing the vulnerability of an MRE system to potential cyber threats and the consequences a cyberattack would have on the end user. This Part 2 publication describes an approach to select appropriate cybersecurity best practices commensurate with the MRE system's cybersecurity risk. The guidance includes 86 cybersecurity best practices, which are associated with 36 cybersecurity domains and grouped into nine categories. The best practices follow the core functions of the National Institute of Science and Technology Cybersecurity Framework (e.g., identify, detect, protect, respond, and and recover) and insights from both maritime and energy industry guidance documents to identify security measures effective in protecting information and operational technology assets prevalent in MRE systems.

Abstract:
Marine Renewable Energy (MRE) is a promising source of energy for the future. However, it is still under development and many challenges need to be overcome to develop competitive solutions. While the design of the station keeping system of traditional offshore oil and gas structures is driven mainly by their low frequency motions, MRE devices are installed at nearshore locations and move dynamically. Because of these criteria, MRE mooring systems require novel mooring systems and associated standards. MRE mooring standards need to take into account the highly dynamic behaviour of these systems, which can lead to large mooring loads. The nature of these loads needs to be investigated to improve the confidence in mooring design and to improve cost-effectiveness. The aim of this thesis is to develop the understanding of peak mooring loads on highly dynamic mooring systems, in particular, the environmental conditions associated with the loads. In addition, preliminary research into the response of the mooring systems to environmental conditions is presented. Both field tests and tank tests have been conducted. Field tests give insight into the behaviour of a dynamic mooring system in real sea conditions. Measuring the mooring loads and the environmental conditions - wave, and current if available – for several months, a methodology has been developed to detect peak mooring loads and identify the associated environmental conditions in order to compare them with the environmental conditions recorded throughout the field tests. The principal finding is that peak mooring loads occur for sea states with large but not always the highest significant wave height HS. The understanding of the effect of tidal conditions on peak mooring loads requires further work. A tank test of a dynamic mooring system in moderate sea states has been conducted to observe the dynamic behaviour of the mooring system. Tank tests enable detailed observations of the dynamic behaviour of a system in a well controlled environment and allow the calibration of a numerical model. The model can be used to investigate separate physical parameters. The results from this thesis will assist in the development of specific standards for MRE mooring systems. These standards are essential for the evolution of the MRE industry.

Abstract:
The development of marine renewable energy is attracting increasing attention due to its great potential in meeting human energy demands with limited negative environment impact. Various wave energy converter concepts have been proposed in attempt to convert wave energy into usable energy. Both experimental and numerical methods have been widely used to investigate the hydrodynamic performance of these devices in operational conditions and their survival characteristics in extreme sea states. This study focuses on developing a numerical procedure that can predict wave loads and run-up on fixed and moving offshore and coastal structures more accurately. The wave induced motions of flap-type wave energy converter (WEC) and its efficiencies are also investigated. The ultimate objectives of the study are to develop a rigorous approach for the safe and cost efficient design of general offshore structures and leading to the better design of wave energy converters with increased efficiency, and provide best practice guideline to the wave energy converter developers and researchers and engineers in the field. Non-linear hydrodynamic modelling in viscous flow has been used in the simulations. Even for moderate waves, nonlinear effects are important due to wave-structure interaction and also the expected large motions under operational conditions. It seems likely that estimates of performance will be unreliable unless the nonlinear effects associated with such large amplitude motions are properly accounted for. Extreme conditions are also be analysed to ensure device integrity. OpenFOAM, a free, open-source CFD package, has been applied in this work due to its strong capability in coastal and offshore engineering. The built-in viscous solvers interFoam and interDyMFoam have been selected and extended to model wave interactions with fixed and moving offshore and coastal structures, respectively. The solvers have been firstly extended to generate various wave conditions, including regular waves, focused wave groups and tsunami waves etc. New module has also been developed to advance the wave absorption capability in attempt to reduce computational cost of the numerical model by using smaller computational domain. In order to simulate the motion of WECs in waves, the code has been further developed to have functions on determining the wave-induced motions of WECs and on updating the computational domain automatically according to the motion of the WEC. By comparing with published experimental data, theoretical and numerical results on various physical problems, including wave interactions with varied seabed, a fixed vertical circular cylinder, a rotating half-submerged rectangular barge and a flap-type wave energy converter etc. it is confident to say that OpenFOAM is very capable of modelling nonlinear wave interactions with coastal and offshore structures accurately.

Abstract:
L’installation des énergies marines renouvelables s’effectue dans le respect des législations environnementales françaises. La séquence Eviter-Réduire-Compenser (ERC) est ainsi appliquée pour aboutir à une non-perte nette de biodiversité. L’objectif de la thèse est de questionner l’efficacité de cette séquence, et plus particulièrement celle de la compensation écologique, en tant qu’instrument d’internalisation et de lutte contre l’érosion de la biodiversité marine. Une approche empirique qualitative a ainsi été mise en oeuvre pour (i) identifier les facteurs écologiques et sociétaux ainsi que leurs caractéristiques théoriques qui doivent permettre à la compensation d’atteindre l’objectif de non-perte nette de biodiversité ; et (ii) contrôler si ces conditions sont vérifiées en pratique dans le cas de l’éolien en mer en Europe et en France. L’analyse met en avant les enjeux juridiques, institutionnels, méthodologiques et sociétaux à relever pour permettre à la compensation écologique d’atteindre son objectif. Sur la base de ce constat, une évaluation multicritères est proposée afin de renforcer les étapes d’évitement et de réduction pour finalement mieux définir les besoins de compensation écologique en mer. L’analyse met par ailleurs en évidence un glissement d’une compensation basée sur une équivalence écologique stricte à une compensation fondée sur une équivalence écologique relâchée. Les actions de compensation tendent à être plus généralistes et/ou davantage dirigées vers les services écosystémiques que sur les composantes des écosystèmes. Associées aux mesures d’accompagnement, elles peuvent contribuer à faciliter l’acceptabilité sociale d’un projet d’aménagement
The installation of marine renewable energies is carried out in compliance with French environmental legislation. The mitigation hierarchy is thus applied to achieve an objective of no net loss of biodiversity. This thesis aims at questioning the effectiveness of the mitigation hierarchy and more specifically biodiversity offsetting as an internalization instrument to halt the erosion of marine biodiversity. We use a qualitative empirical approach to (i) identify the ecological and societal factors as well as their theoretical characteristics that are supposed to enable the offsets achieving the objective of no net loss of biodiversity; and (ii) control whether these conditions are verified in practice for the case of offshore wind farms in Europe and France. The analysis highlights the legal, institutional, methodological and societal issues to be addressed in order to enable biodiversity offsetting to achieve the no net loss priority. On the basis of this observation, a multi-criteria assessment is carried out to reinforce the avoidance and reduction steps of the mitigation hierarchy in order to better define offsetting needs. Ultimately, the analysis shows a shift in biodiversity offsetting based on a strict ecological equivalence to a biodiversity offsetting based on a released ecological equivalence. Offsetting actions tend to be more generalist and / or more directed to ecosystem services than to ecosystem components. Associated with accompanying measures, offsetting actions can help to increase the social acceptability of a development project

Abstract:
Cette thèse présente les trois approches : analytique, expérimentale et numérique développées pour étudier le comportement d'une hydrolienne à membrane ondulante. Cette technologie, portée par l'entreprise EEL Energy, est basée sur les déformations périodiques d'une structure flexible pré-contrainte. Des convertisseurs d'énergie, positionnés de part et d'autre du système, sont actionnés par le mouvement d'ondulation.Analytiquement, la membrane est représentée par un modèle linéaire de poutre à une dimension et l'écoulement par un fluide potentiel 3D. L'action du fluide sur la membrane est évaluée par la théorie des corps élancés. L'énergie est dissipée de façon continue sur la longueur de la membrane. Expérimentalement, un prototype à l'échelle 1/20ième a été développé, des micro-vérins permettent de simuler l'énergie produite. Les essais avec le prototype1/20ième ont permis de valider le concept d'hydrolienne à membrane ondulante et le mode de récupération d'énergie. Un modèle numérique 2D éléments finis a été mis au point. Chaque élément constitutif de la membrane y est reproduit, la dissipation d'énergie est réalisée par des éléments dissipatifs mais la loi d'amortissement est limitée à un amortissement linéaire en vitesse.La comparaison des résultats issus de ces trois modèles a permis de valider leur bonne capacité à reproduire le comportement de la membrane sans conversion d'énergie. La dissipation d'énergie appliquée avec le modèle analytique se distingue clairement des deux autres modèles de part sa localisation mais aussi par la loi d'amortissement utilisée. Les autres modèles sont cohérents entre eux et si on ne parvient pas à corréler les résultats de puissance dissipée, le comportement du système et la répartition de la puissance dissipée le long de la membrane sont semblables. Ces trois approches ont permis de mettre en avant les paramètres clés dont dépend le comportement de la membrane et l'étude paramétrique démontre la complémentarité et l'intérêt du développement conjoint des modèles dans un souci industriel d'optimisation du système. Le développement d'un prototype à l'échelle supérieure (1/6ème), devant faire le lien entre les essais en bassin et les essais en mer, a permis de travailler sur les effets d'échelle. Des différences de comportements sont observées entre ces deux prototypes mais elles sont dues en partie à des différences de conditions aux limites et en partie à des effets de confinements très importants. Pour évaluer la tenue sur le long terme du prototype, ses composants (composite, élastomère) ont été caractérisés précisément et des essais de vieillissement accéléré par température ainsi que des essais de fatigue ont été mis en place sur des échantillons de matière
This manuscript presents three approaches : analytical, experimental and numerical, to study the behavior of a flexible membrane tidal energy convertor. This technology, developed by the EEL Energy company, is based on periodic deformations of a pre-stressed flexible structure. Energy convertors, located on each side of the device, are set into motion by the wave-like motion.In the analytical model, the membrane is represented by a linear beam model at one dimension and the flow by a 3 dimensions potential fluid. The fluid forces are evaluated by the elongated body theory. Energy is dissipated all over the length of the membrane. A 20th scale experimental prototype has been designed with micro-dampers to simulate the power take-off. Trials have allowed to validate the undulating membrane energy convertor concept. A numerical model has been developed. Each element of the device is represented and the energy dissipation is done by dampers element with a damping law linear to damper velocity.Comparison of the three approaches validates their ability to represent the membrane behavior without damping. The energy dissipation applied with the analytical model is clearly different from the two other models because of the location (where the energy is dissipated) and damping law. The two others show a similar behavior and the same order of power take off repartition but value of power take off are underestimated by the numerical model. These three approaches have allowed to put forward key-parameters on which depend the behavior of the membrane and the parametric study highlights the complementarity and the advantage of developing three approaches in parallel to answer industrial optimization problems.To make the link between trials in flume tank and sea trials, a 1/6th prototype has been built. To do so, the change of scale was studied. The behavior of both prototypes is compared and differences could be explained by differences of boundary conditions and confinement effects. To evaluated membrane long-term behavior at sea, a method of aging accelerated by temperature and fatigue tests have been carried out on prototype materials samples immerged in sea water

Abstract:
Fishers are among the biggest commercial resource users in the marine environment. In order to meet international, national and local policies, the UK has to designate a suite of marine protected areas (MPAs) and reach marine renewable energy (MRE) targets. Inevitably, there will be conflict between these two industries and marine conservation. This study uses a multi-disciplinary approach to examine evaluate the suitability of various sources of data, which could be used to detect, assess, and ultimately predict, fishing effort displacement within the different sectors of the > 15 m fleet in the South West of the UK. Gear-specific Vessel Monitoring System (VMS) data from 2005-2008 was used to assess potential effort displacement due to Haig Fras, a proposed MPA and Wave Hub, a marine renewable energy installation (MREI). The spatial distribution of fishing activity was highly heterogeneous and distinct areas of intense fishing could be identified for all gear-types. A closure of Haig Fras would have the greatest impact on gillnetters. Scallop dredgers also occasionally use the area. The current closure at Wave Hub has the greatest impact on potters and whelkers whose geographic specialisation is most pronounced and who use the area extensively. Longliners also use the area disproportionately would be affected. A simple index of variability was developed in order to determine baselines and two other sources of data were used. High resolution seabed data and low resolution catch data. A semi structured interview was conducted with forty fishers to elicit further information on the challenges, barriers to progress and priority issues in relation to MRE those fishers face. The theme of discontent with the consultation process scored highly throughout. Fishers’ Knowledge (FK) another source of data also scored highly, although further work must be carried out to identify what aspects of this data are useful in assessment of fishing effort displacement.

Abstract:
Marine currents, i.e. water currents in oceans and rivers, constitute a large renewable energy resource. This thesis presents research done on the subject of marine current energy conversion in a broad sense. A review of the tidal energy resource in Norway is presented, with the conclusion that tidal currents ought to be an interesting option for Norway in terms of renewable energy. The design of marine current energy conversion devices is studied. It is argued that turbine and generator cannot be seen as separate entities but must be designed and optimised as a unit for a given conversion site. The influence of support structure for the turbine blades on the efficiency of the turbine is studied, leading to the conclusion that it may be better to optimise a turbine for a lower flow speed than the maximum speed at the site. The construction and development of a marine current energy experimental station in the River Dalälven at Söderfors is reported. Measurements of the turbine's power coefficient indicate that it is possible to build efficient turbines for low flow speeds. Experiments at the site are used for investigations into different load control methods and for validation of a numerical model of the energy conversion system and the model's ability to predict system behaviour in response to step changes in operational tip speed ratio. A method for wake measurements is evaluated and found to be useful within certain limits. Simple models for turbine runaway behaviour are derived, of which one is shown by comparison with experimental results to predict the behaviour well.

Baker, Nicholas Jon. "Linear generators for direct drive marine renewable energy converters." Thesis, Durham University, 2003. http://etheses.dur.ac.uk/696/.

Full text
Abstract:
This thesis is concerned with the development of linear generators for use as the power take off mechanism in marine renewable energy converters. Delivering significant power at the low velocities demanded by wave and tidal stream energy converters requires a large force, which must be reacted by an electrical machine in a direct drive system. Attention is focused on the development of two novel topology linear permanent magnet machines suitable for use in this application. For each topology, models are presented that are capable of predicting the force characteristics and dynamic generator performance. The models, which are verified experimentally, reveal significant behavioural differences between the two topologies. The designer is thus provided with an interesting choice when considering a direct drive power take off strategy. In short, a variable reluctance machine is shown to develop a high shear force in its airgap, offering the potential of a compact generator, yet its performance is hindered by a poor power factor and the presence of significant airgap closure forces. The second machine, an air cored stator encompassing a permanent magnet translator, is shown to lend itself favourably as a generator, but only at the expense of requiring a large quantity of magnetic material and developing a significantly lower shear stress. Mechanical issues involved in the direct integration of linear electrical machines into the marine environment are examined. Details of two existing marine renewable energy devices are used to hypothesise about the characteristics of realistic sized generators of both the topologies investigated. Direct drive power take off is shown to represent a feasible alternative to the complex systems frequently proposed in these applications.

Abstract:
Human exploration of the hydrosphere is ever increasing as conventional industries grow and new industries emerge. A new emerging and fast-growing industry is the marine renewable energy. The last decades have been characterized by an accentuated development rate of technologies that can convert the energy contained in stream flows, waves, wind and tides. This growth benefits from the fact that human society has become notably aware of the well-being of the environment that we all live in. This brings a human desire to implement technologies which cope better with the natural environment. Yet, this environmental awareness poses difficulties in approving new renewable energy projects such as offshore wind, wave and tidal energy farms. Lessons have been learned that lack of consistent environmental data can become an impasse when consenting permits for testing and deployments marine renewable energy technologies. An example is the European Union in which a majority of the member states requires rigorous environmental monitoring programs to be in place when marine renewable energy technologies are commissioned and decommissioned. To satisfy such high demands and to simultaneously boost the marine renewable sector, long-term environmental monitoring framework that gathers multi-variable data are needed to keep providing data to technology developers, operators as well as to the general public. Technologies based on active acoustics might be the most advanced tools to monitor the subsea environment around marine manmade structures especially in murky and deep waters where divining and conventional technologies are cost. The main objective of this PhD project has develop and test an active acoustic monitoring system for offshore renewable energy farms, by integrating a multitude of appropriate monitoring sonar, hydrophones and cameras systems to be developed with standards suitable for subsea environmental monitoring. In this project, a first task was to identify, secondly acquire and test sonar systems, then a platform was designed and built, a data acquisition device control systems were developed, finally additional instruments such as video cameras and sonars were added. This systems integration followed by calibration of devices was conducted. The sonar systems were used for quantitative measurements of the occurrence of e.g. large marine animals and schools of fish near marine renewable energy converters. The sonar systems were also used for seabed inspections, depth measurements and capitating flow observations. So far, the combination of multibeam and dual-beam sonar systems produced good results of target detection, bottom inspection, depth measurements and biomass estimation. The multibeam sonar system was capable of resolving isolated targets located near high acoustic retroreflective objects. Panoramic acoustic images of wave and instream energy converters were acquired using a multibeam sonar operating at frequencies near 1 GHz. The Dual-beam and split-beam sonar systems produced data referent to acoustic background intensity of targets that helps to classify targets according to its size, composition and 3-Dimensional location within the water column. The next phase of this project will deploy the platform for longer periods in order to gather consistent acoustic and optical backscattering data of marine animal behaviour within marine renewable energy farms.

Abstract:
This thesis involves an examination of the main international, regional and national legal regimes regulating marine renewable energy in England and Wales. Deriving from a complex patchwork of law and policy, developments have ensued in the absence of a distinct governing ‘legal regime’ and within a number of competing paradigms. This original synthesis attempts to identify lacunae, conflicts and connections within and between the span of legal genres that MRE evokes. Against a backdrop of climate change mitigation, the key findings show that despite the presence of political will for offshore renewable energies, MRE development faces a number of legal obstacles, all of which seek to protect other important public and private interests. Although predominantly satisfactory at the international level (international law of the sea), national private property rights, environmental protection laws and regulatory development controls each encompass particular legal incongruities that have the potential to act as barricades to development. This thesis discusses these issues and reaches conclusions as to potential areas for reform.

Abstract:
As is the case with many countries, Namibia has an economy dependent on fossil fuels. The country is, however, blessed with abundant and diverse - but as yet unexploited - renewable energy (RE) resources that could be used for improving the livelihood of the vast majority of its 2.2 million people. Today the conflict between energy production from fossil fuels and protection of the environment is intensifying and this compels all countries to search for means of resolving this conflict. Developing RE through the enactment of enabling legislation and implementation of relevant policy is one important step towards attaining the ideal of an energy-secure future. This state of affairs is not unique to Namibia, as most countries with abundant RE sources are striving to promote and deploy RE in their respective regimes through appropriate policies and legal frameworks. This study examines Germany and Ghana from, respectively, the developed and developing world, as leading countries that have established a proactive RE regime. However, such a regime can only be successfully achieved if countries, including Namibia, adopt laws and policies that promote and encourage the use of RE in order to move away from fossil fuel dependence to a greener economy. Thus the study seeks to investigate RE resources in Namibia and their potential development. It outlines the current legislation pertaining to the regulation of RE in Namibia. As such, the study further examines the Organisation for Economic Cooperation and Development (OECD) guidelines and draws examples from other regimes, particularly Germany and Ghana, in order to provide a guideline for the enactment of a general Energy Act with a particular chapter on RE. It concludes with recommendations as to how Namibia can secure a sustainable energy future.

Abstract:
The combination of Marine Renewable Energy (MRE) technologies such as wave or current devices with offshore wind, a more mature technology, could enable pooling of R&D efforts and reducing costs (grid connection, moorings, maintenance activities…). Moreover, the different characteristics of the wind, wave and current resources could be complementary and provide a smoothing effect on the power production. Therefore, the EU FP7 project -MARINA Platform- aims at studying concepts of combined platforms integrating different types of MRE devices. Many challenges are induced by these innovative platforms and guidelines and standards will be required to ensure safety, reliability and quality. However, as the concepts are only at the development stage, no standards have been written for these combined platforms so far. This paper presents a new approach proposed by Bureau Veritas within the scope of the MARINA project for the development of guidelines and standards dedicated to combined MRE platforms. Existing literature on standards about MRE and related sectors, like shipping, wind energy and offshore oil & gas, forms a good basis to be exploited. In addition, risk assessment and qualification of new technology might be considered as a complement to standards to support the design of novel offshore concepts. Therefore, the presented methodology combines the use of existing standards from MRE and related sectors with a risk-based approach for the most innovative and unknown parts of the platform. A global risk assessment is performed in parallel for a whole review of the system.

Abstract:
An increasing use of submarine power cables is found in dynamic applications such as floating wind, floating wave and tidal generation technologies. These applications substantially differ from common applications, such as floating oil and gas installations in that they are more dynamic. Power cables that cross the water column, so-called umbilicals will be exposed to considerable extreme and fatigue loads mainly induced by the motion of the device, incident waves and tidal current. The actual loading regimes of dynamic submarine power cables in operation are not well understood for marine renewable energy (MRE) applications due to a lack of field experience. The cable design has to consider a combination of cable geometry, hydrodynamic parameters, suitable layout configuration, suitable ancillary systems (e.g. bend stiffeners) in relation to the environmental site conditions. This paper evaluates the influence of the environmental conditions and the cable design parameters on the mechanical loads and potential failure modes of a dynamic submarine power cable attached to a dynamic floating body in form of a generic point absorber. One notable result is the large effect of the tidal direction, even in relatively moderate flow conditions. The full range of tidal flow conditions should be considered in the power cable design to ensure that the cable MBR is not exceeded in any conditions. The shown configurations also give some insight into the possible variations of the geometric cable configuration. A well balanced S-curve shape yields some of the best results and achieves a good load distribution along the cable and the transition points, whilst avoiding cable compression. The design challenge for the cable configuration is to maintain the S-shape for as many environmental and device response modes as possible in order to achieve high reliability. This paper will be useful for cable, device and site developers of floating MRE to inform the selection of the most suitable cable design.

Abstract:
Recovery of marine energy is progressing from the prototype stage to arrays, and all of the systems currently being developed include critical elements manufactured from polymers and composites. Structural MRE (Marine Renewable Energy) components range from composite turbine blades, for floating wind and tidal turbines, to polymer fiber ropes for wave, tidal and floating wind mooring systems. Elastomeric components are also widely used for sealing and protection. In all cases it is essential to understand how seawater diffuses into these polymers and how it affects mechanical properties; this allows appropriate safety factors to be applied without excessive over-conservative design, and can result in significant cost reduction. This paper will present a methodology for evaluating the long term behavior of such components based on accelerated testing. Three examples will be shown to illustrate the approach; tidal turbine blade composites, synthetic fiber rope moorings, and rubber components. In each case the seawater diffusion kinetics will be described first, then the influence of water on mechanical behavior will be quantified for the particular loadings of interest, and finally results from fully coupled fatigue tests in seawater will be discussed.

Hydrogen can be produced from various primary resources by using different processes. The full benefits of hydrogen production can be obtained when it is produced from renewable energy resources. Among these emerging renewable energy resources, marine and hydrokinetic (MHK) energy systems lower variability in the energy production. Also, more than 50% of the total US population resides near water bodies. In this paper, a brief review of renewable energy-based hydrogen production systems is provided, the emission level of both conventional and renewable energy sources for producing the same amount of hydrogen are compared using GREET model, and research needs for further MHK-based hydrogen production systems are discussed. The results showed the significant emission reductions obtained from renewable-based hydrogen production systems. Moreover, the study showed the potential of producing the same amount of hydrogen with less resource quantity of wave energy compared to that from other renewables such as solar energy.

Abstract:
Floating Offshore Wind Turbines (FOWT) are promising Marine Renewable Energy (MRE) technologies. Considering the emerging stage of development of MRE technologies, no dedicated certification scheme has been developed so far by international organizations. Technical specifications are under development in the framework of the International Electrotechnical Commission (IEC) Technical Committee (TC) 88 and IEC Renewable Energy (IECRE). Within IECRE, the Marine Energy Operational Management Committee (ME OMC) is in charge of the development of a conformity assessment system dedicated to Floating Wind Turbines. In this context, Bureau Veritas (BV) has issued a Guidance Note NI631 Certification Scheme for Marine Renewable Energy Technologies and also the NI572 for the Classification and Certification of FOWT to support technology developers and speed up commercial phases. The note NI631 describes the different schemes of MRE certification, whereas the NI572 details the technical requirements for FOWT. This paper will provide an overview of the certification schemes applicable to FOWT technologies, addressing prototype, component, type and project certification. Main objective, scope, intermediary steps to be completed and resulting certificates will be detailed for each certification scheme, as well as their interactions. A methodology relying on the qualification of new technology process will be detailed when no guidelines or standards are available for the most innovative parts of a FOWT, or when existing standards from related sectors, such as wind energy, shipping or offshore Oil&Gas, require adaptations to fit their requirements to the specific MRE conditions.

Abstract:
With widespread market penetration in the offshore sector, synthetic rope materials offer a range of axial compliance that can be exploited for mooring design, ranging from stiff (e.g. high modulus polyethylene) to soft (e.g. nylon). For new applications, such as the marine renewable energy (MRE) sector synthetic ropes are potentially an enabling technology due to their load reduction properties and relative low cost compared to conventional mooring component materials. Existing design, test and certification procedures for ropes were developed for the station keeping of large offshore equipment. Arrays of small, reactive MRE devices will have an entirely different set of mooring load cases with the mooring system potentially an integral part of the power take off system. Larger devices are also likely to be subjected to complex loading as MRE deployment sites are typically highly energetic in terms of wind, wave and/or tidal energy. Consequently devices and associated subsystems are subjected to dynamic load cases in a wide range of complex environmental and operating conditions. Underpinning research is therefore required to understand the behaviour of synthetic materials subjected to highly dynamic loading regimes in terms of operational performance and long-term durability as these factors could have a significant impact on coupled device performance and availability. At present conventional mooring analyses is based on the use of simplified rope characteristics, although several studies including a Joint Industry Project (Syrope) have investigated these aspects. However, at present an industry-standard method to account for the time-varying behaviour of synthetic ropes for offshore equipment moorings does not exist. The SynMaRE (Synthetic ropes for Marine Renewable Energy mooring systems) project aims to develop a time domain analytical model that can adequately represent the time dependent and non-trivial behaviour of synthetic ropes. Instead of being a stand-alone tool, it is intended that the model will be adopted for incorporation in (or with) commercial mooring system software allowing the prediction of mooring loads and device responses to an increased level of accuracy. This paper will present findings from an initial assessment of parameter estimation techniques utilising a simplified viscoelastic and viscoplastic model and validation scenarios based on physical tension-tension test data featuring load cases relevant to MRE mooring systems.

Full text
Abstract:
Fuel costs, which are the single most important driver of marginal costs for marine transportation, account for almost 50% of total voyage costs for typical configurations and operational modes. Hence, there has developed a desire among operators and manufacturers of all classes of ships to embrace innovative ways to reduce the demand for fuels. The luxury yacht segment presents an attractive market for investigating and assessing the impacts of fuel-saving technologies because the large ships benefit from the fuel savings, have more flexible performance requirements and have owners who are more likely to embrace the required premiums for experimental technologies. This report analyzes the effects of fitting such a yacht with a sail system, a solar panel system, and an energy storage system (ESS). Integrating a sail system to reduce propulsion loads provides significant benefit with respect to fuel economy. In contrast, the total amount of power provided by the solar panel system provides very little benefit, even when extensive deck paneling is used and panels are fit to rigid wing sails. Utilizing an ESS in the same manner as with a terrestrial hybrid vehicle to manipulate load distribution provides insignificant benefit for fuel consumption reduction, but seems to present opportunities for emissions reduction, which has played an increasingly important role in marine environmental concerns.

Full text
Abstract:
Abstract Improving the reliability of marine renewable energy devices such as wave and tidal energy convertors is an important task, primarily to minimize the perceived risks and reduce the associated cost for operation and maintenance. Marine systems involve a wide range of uncertainties, due to the complexity of failure mechanism of the marine components, scarcity of data, human interactions and randomness of the sea environment. The fundamental element of a probabilistic risk analysis necessarily needs to rely on operational information and observation data to quantify the performance of the system. However, in reality it is difficult to ascertain observation of the precursor data according to the number of component failures that have occurred, mainly as a result of imprecision in the failure criterion, record keeping, or experimental and physical modelling of the process. Traditional reliability estimation approaches such as Fault Tree, Event Tree and Reliability Block Diagram analysis offer simplified, rarely realistic models of this complex reliability problem. The main reason is that they all rely on accurate prior information as a perquisite for performing reliability assessment. In this paper, a hierarchical Bayesian framework is developed for modelling marine renewable component failures encountered the uncertainty. The proposed approach is capable to incorporate the conditions, which lack reliable observation data (e.g. unknown/uncertain failure rate of a component). The hierarchical Bayesian framework provides a platform for the propagation of uncertainties through the reliability assessment of the system, via Markov Chain Monte Carlo (MCMC) sampling. The advantages of using MCMC sampling has proliferated Bayesian inference for conducting risk and reliability assessment of engineering system. It is able to use hyper-priors to represent prior parameters as a subjective observations for probability estimation of the failure events and enable an updating process for quantitative reasoning of interdependence between parameters. The developed framework will be an assistive tool for a better monitoring of the operation in terms of evaluating performance of marine renewable system under the risk of failure. The paper illustrates the approach using a tidal energy convertor as a case study for estimating components failure rates and representing the uncertainties of system reliability. The paper will be of interest to reliability practitioners and researchers, as well as tidal energy technology and project developers, seeking a more accurate reliability estimation framework.

Abstract:
This publication assesses the potential for deployment of the leading Marine Renewable Energy (MRE) technologies including Fixed Offshore Wind, Floating Offshore Wind, Ocean Thermal Energy Conversion across nine Countries of Interest (COI) in the Caribbean region. This is achieved by conducting a technology review, analysing resource levels in each of the COIs, and presenting the outputs of Locational Guidance work identifying preferred areas for potential future project development. This work concludes that MRE can offer a secure supply of indigenous clean energy, that resources are sufficiently abundant to meet the current and future energy demand of each of the COIs many times over, and that the leading MRE technologies are sufficiently advanced to be worthy of immediate prioritisation. This Technical Note draws on and presents outcomes from work undertaken in 2019 as part of a Technical Cooperation Agreement between the IDB and CDB under the Support for Sustainable and Resilient Projects in the Caribbean programme.
