Kepulauan Seribu Marine National Park (TNKpS) which is the only national park in the world located in a capital city, is included as a part of the Kepulauan Seribu Administrative Regency, DKI Jakarta Province. Based on the decree of the Director of Forest Protection and Nature Conservation Number SK.05/VI-KK/2004 concerning the Zonation of the Kepulauan Seribu Marine National Park, not all TNKpS areas can be used as tourism destinations, because there are zones aimed at conservation of natural resources. According to the decree, TNKpS area is divided into 4 zones, namely the Core Zone, Protection Zone, Tourism Utilization Zone and Settlement Zone. One of the residential islands in TNKpS which is also the main destination for tourists for transit, is Harapan Island. Apart from being the main destination for tourists for transit, Harapan Island is the largest island in Seribu Utara sub-district. The cost of traveling to Kepulauan Seribu, especially to Harapan Island, is very affordable, between IDR 350,000 to IDR 400,000. This affordable cost makes Harapan Island a priority natural tourist destination for residents of Jabodetabek (Jakarta, Bogor, Tangerang, and Bekasi). Many tourism activities on Harapan Island have not only a positive impact on the local economy but also a negative impact on the environment. There are a lot of rubbish such plastic snack waste and damaged coral reefs in the snorkeling spots. The concept of Willingness to Pay (WTP) of tourists is the willingness of tourists to pay for the assessment of natural resources in order to improve environmental quality in the Harapan Island area. This study aims to estimate the WTP of tourists to travel on Harapan Island. The design of this study used quantitative methods by collecting data through interviews and distributing questionnaires online. The data were processed by descriptive method and the Contingent Valuation Method (CVM). The results show that the WTP of tourists is as much as IDR 32,976/person/visit that can be included in the price of a tour package. As much as IDR 518,161,947 per year is expected to help the costs of nature conservation on Harapan Island.
Keywords: Kepulauan Seribu Marine National Park (TNKpS), Harapan Island, Contingent Valuation Method (CVM), Willingness to Pay (WTP).

Sea turtles perform various ecological services in several marine environments and are considered architects of the marine landscape. At present, they are endangered species due to anthropogenic threats, pollution and degradation of marine habitats. These impacts make it urgent to increase protection and conservation efforts. Protective actions include the rescue and rehabilitation of injured individuals as a result of their interactions with humans and other threats. Environmental enrichment (EE) is a series of techniques and methods aimed to improve the welfare of animals in captivity and/or under rehabilitation. It uses external stimuli to enhance their psychological and physiological wellbeing to promote natural abilities and behaviors. These may increase the survival chances of rehabilitated animals upon release in the wild. This review presents data of studies where EE has been applied during the rehabilitation processes of different species of sea turtles, and its effect on welfare improvement during captivity/rehabilitation and on survival after release into nature. Technologies such as satellite tags are an important means to determine rehabilitation success and survival of injured individuals from endangered species after release into the wild, as they allow tracking and monitoring of such individuals, and determine their location in areas used by their natural populations for feeding or breeding.

The results of this study indicate that the percentage of potential coral reef cover at all stations is 10-36%, indicating that the coral condition is not good (according to the conditions). Damage to coral reef ecosystems due to environmentally unfriendly fishing activities (Wardani, 2018). The number of lifeform types ranged from 8-12, while the number of fish species obtained was 37-44 species. The suitability class category based on the results of the analysis at the three stations obtained the appropriate category (S2), with a percentage of the IKW value of 50-67% (Yulianda, 2018). Then, area carrying capacity (DDK) in the diving tourism category is an average of 528 people / day from the three stations. Management and development of marine tourism can be done by determining the zone of utilization and rehabilitation of coral reef ecosystems, as well as limiting visitors for certain periods to reduce the potential impact of environmental degradation.

Environment is in continuous change to serve life in various forms on land and water. The cost of these services result negative changes in environment resulting pollution. It moves to oceans either it is generated inside or outside. Plastic pollution is most irreparable among these. It tends to minimize and stop environmental rich activities. Furthermore it moves towards destruction of physical and biological systems in marine environments. It results ecosystems damage and economy failure.

This publication comprises proceedings of a marine conservation forum. Why are marine environments ?out of sight out of mind?? Good question, however, I was a little disappointed to find that generally it was not addressed and consequently, I do not believe that this forum has done much to progress marine conservation. For the most part it was only Harry Recher?s forward and the Summary paper by Pat Hutchings and Dan Lunney, which made an attempt to answer this question; they argued for, at least to some extent, the human aspect of marine conservation. That might be a little unfair on Sarah Fairfull and Robert Williams, who in presenting the new age of regional delivery of natural resource management through acknowledged peak regional groups, also acknowledge the role that communities can now serve in setting conservation priorities.

Full textAbstract:
Whereas the conservation and management of biodiversity has become a key issue in environmental sciences and policy in general, the conservation of marine biodiversity faces additional challenges such as the challenges of accessing field sites (e.g. polar, deep sea), knowledge gaps regarding biodiversity trends, high mobility of many organisms in fluid environments, and ecosystem-specific obstacles to stakeholder engagement and governance. This issue comprises contributions from a diverse international group of scientists in a benchmarking volume for a common research agenda on marine conservation. We begin by addressing information gaps on marine biodiversity trends through novel approaches and technologies, then linking such information to ecosystem functioning through a focus on traits. We then leverage the knowledge of these relationships to inform theory aiming at predicting the future composition and functioning of marine communities. Finally, we elucidate the linkages between marine ecosystems and human societies by examining economic, management and governance approaches that contribute to effective marine conservation in practice. This article is part of the theme issue ‘Integrative research perspectives on marine conservation’.

Full textAbstract:
This study explores the factors that influence the management of a protected area situated on private land as well as the implications of these factors in the interaction between the NGO and the communities associated with this area. The protected area, Marine National Monument Cayos Cochinos, is an archipelago surrounded by reefs in the Honduran Caribbean. This area is home to a highly heterogeneous population of fisherfolk communities –most are members of the Garifuna ethnic group– and wealthy Honduran and foreign landowners. This case study also comprises three fisherfolk communities outside the protected area who fish in Cayos Cochinos. Local fishermen in Cayos Cochinos are settled in community-owned areas; however, these settlements started by the occupation of private lands. Wealthy landowners have either individual land titles or shares of a firm owning four of the islands. The protected area was established through the initiative of this firm to protect the natural resources. This area is nominally co-managed by a local nongovernmental organisation (NGO) and two government agencies; however in practice it is managed solely by the NGO. This study discusses the influence of the nature of the Honduran legislation regarding protected areas and of the co-management agreement on the management of Cayos Cochinos. This research also shows that the management priorities of this protected area are only partially based on the Honduran government’s laws and regulations and the guidelines specific for this area. Lack of government participation in the co-management of the area, financial constraints, influences on the NGO of stakeholders in higher positions of power with respect to it, personal preferences of the NGO managers and issues regarding the communities’ leadership, have all had an influence on the management priorities of the protected area since its constitution. The combined effect of these factors has influenced the management of the NGO towards prioritising the natural resource conservation. This area is managed under a ‘people-out’ conservation paradigm. The adoption of this paradigm has disadvantaged the fisherfolk communities inside and outside the protected area by restricting their access to the natural resources on which their livelihoods are highly dependent. However, the same situation has favoured the private landowners by limiting the access of the fisherfolk communities to the land owned by the former. The privileging of one community sector over another has created conflicts between the NGO and the fisherfolk communities. However, these conflicts have been fuelled by other factors such as the steady contesting of the land titles over the territories occupied by the latter, and by the support that external organisations have given to the latter at the expense of the original owners of the land. This research suggests that local NGOs in charge of the management of natural protected areas might have limited capacity to abide by national conservation and sustainable development priorities due to the likelihood to be influenced by external forces with different priorities.

Several types of mechanisms can influence community structure of fishes in marine ecosystems, such as larval recruitment, interaction between species, abiotic factors, composition and percent cover of benthic organisms, mainly providing a relationship of habitat complexity with higher abundance and structural diversity. In this context, this study aimed to survey the reef fish fauna of coastal habitats located in the Parque Estadual Marinho Areia Vermelha, with emphasis on habitat characteristics, distribution patterns and conservation aspects recorded species in the area. The study site was divided into sampling stations according to the history of tourism activity: Areia Vermelha (AV - longer visiting history), Areia Dourada (AD - recent visiting history) and No Visit (SV - adjacent area - no visiting history). The stations were sampled by the method of stationary visual census in free-diving, with the average duration of 15 minutes and between December 2009 and April 2010, December 2010 and January 2011. Among the types of substrate coverage analyzed, there was a dominance of sessile invertebrates in AD and macroalgae in AV and SV. during the 150 censuses, a total of 6141 specimens were recorded, including by 55 species, distributed in 26 families. Labridae (Scarinae) was the family with highest abundance and Haemulidae the one with highest species richness. The species that yielded the largest number of individuals on the macroalgae environments were Sparisoma axillare, Abudefduf saxatilis, Acanthurus chirurgus, Haemulon parra and Halichoeres brasiliensis, while the reefs were Sparisoma axillare, Abudefduf saxatilis, Acanthurus chirurgus, Scarus zelindae and Halichoeres brasiliensis. Most individuals were found in the juvenile stage. With respect to trophic structure, most sighted individuals were grouped in the category Non-Territorial Herbivores. The environments analyzed in this study proved to be important for juvenile individuals of different species as well as for endangered fishes, indicating the importance of their conservation for the survival of these species.
Muitos mecanismos podem influenciar a estrutura da comunidade de peixes em ambientes marinhos, tais como o recrutamento larval, interação entre as espécies, fatores abióticos, composição e percentagem de cobertura de organismos bênticos, conferindo principalmente à complexidade do habitat uma relação com maior abundância e diversidade estrutural. Diante deste contexto, o presente trabalho objetivou inventariar a fauna de peixes recifais do Parque Estadual Marinho Areia Vermelha, com ênfase na caracterização do habitat, padrões de distribuição e aspectos da conservação das espécies registradas no Parque. A área de estudo foi dividida em estações de coleta de acordo com o histórico de turismo: Areia Vermelha (AV histórico antigo de visitação), Areia Dourada (AD histórico recente de visitação) e Sem Visita (SV área adjacente sem histórico de visitação). As estações foram amostradas pelo método do censo visual estacionário, em mergulho livre, com duração média de 15 minutos e entre dezembro de 2009 a abril de 2010, dezembro de 2010 e janeiro de 2011. Dentre os tipos de cobertura de substrato analisados, houve dominância dos invertebrados sésseis em AD e de macroalgas em AV e SV. Dos 150 censos realizados, foi registrado um total de 6.141 espécimes, representados por 55 espécies e distribuídos em 27 famílias. Labridae (Scarinae) foi o grupo com maior abundância e Haemulidae a família com maior riqueza de espécies. As espécies que perfizeram o maior número de indivíduos nos ambientes de macroalga foram Sparisoma axillare, Abudefduf saxatilis, Acanthurus chirurgus, Haemulon parra e Halichoeres brasiliensis, enquanto nos recifes foram Sparisoma axillare, A. saxatilis, A. chirurgus, Scarus zelindae e H. brasiliensis. A maioria dos indivíduos foram encontrados no estágio juvenil. Em relação às categorias tróficas, a maior parte dos indivíduos avistados foi agrupada na categoria Herbívoros não territorialistas. Os ambientes analisados no presente estudo mostraram ser importantes para indivíduos jovens de variadas espécies, bem como para peixes considerados ameaçados de extinção, o que remete a importância da conservação de tais ambientes para a sobrevivência destas espécies.

Full textAbstract:
Cette thèse porte sur l'étude de l’efficacité d’une Aire Marine Protégée (AMP) comme outil de restauration des ressources marines et de gestion des stocks halieutiques en zone tropicale ouest africaine. L’étude concerne trois AMP. Il s’agit de l’AMP de Bamboung située en zone estuarienne (sous influence marine), à l'intérieur d'un delta et fermée à l’exploitation halieutique depuis 2004. La deuxième AMP est celle des îles d’Urok créée en 2005 et située dans la réserve de biosphère de l’archipel des Bijagos dans la partie littorale de la Guinée-Bissau. Elle est divisée en trois zones et la pêche y est autorisée avec une pression de pêche de plus en plus forte de la zone centrale vers la zone périphérique. La troisième AMP est le Parc National du Banc d’Arguin situé le long de la côte mauritanienne. Il a été créé en 1976 et les activités de pêche y sont pratiquées de façon réglementée. Beaucoup d’AMP ont été évaluées à travers le monde et les résultats obtenus sont dans la majeure partie des cas positifs. Dans les milieux tropicaux, les variabilités interannuelles et intra-annuelles des paramètres environnementaux influent sur l’organisation spatio-temporelle des peuplements de poissons. Par conséquent, la mise en place d’AMP dans une zone tropicale a suscité des interrogations quant à leur efficacité en rapport avec l’influence des paramètres de l’environnement. Selon l’AMP étudiée, une approche spatiale ou temporelle sera utilisée pour répondre aux questions posées. Les méthodes d’analyse utilisées sont de type comparatif. L’analyse des données biologiques est précédée par celle des paramètres physico-chimiques qui a mis en évidence des variabilités saisonnières dans chaque AMP. Ce résultat justifie le choix d’analyser les données biologiques par saison afin de minimiser au mieux l’influence des variations environnementales. En ce qui concerne l’AMP de Bamboung, les résultats de l’analyse suivant une approche globale ont clairement montré son rôle positif dans la restauration des ressources marines. L’approche saisonnière a mis en évidence ce rôle de restauration mais en saison froide et non en saison chaude et humide. En 9 années de protection, l'AMP de Bamboung a contribué au retour de gros poissons dans le bolon de Bamboung. Son rôle dans l’enrichissement de la zone proximale à travers le phénomène de «Spillover» n’a pas pu être mis en évidence. Une tendance à la baisse des indicateurs biologiques en fonction de la distance à l'AMP a été observée surtout en saison chaude et en saison humide. De même l’analyse des indicateurs liés à la reproduction ne montre pas que l’AMP de Bamboung améliore la reproduction des poissons. Concernant, l’AMP des îles d’Urok et le Parc National du Banc d’Arguin, les analyses n’ont pas donné de résultats clairs quant à leur rôle dans l’amélioration des rendements de pêche et de la reproduction des poissons. Cependant, pour l’AMP des îles d’Urok, les tendances observées semble montrer une forte concentration de biomasse dans la zone centrale, un rôle d’équilibre joué par la zone intermédiaire et un rôle de pourvoyeur de biomasse de poisson de la zone périphérique. Pour le PNBA, le secteur intérieur semble contribuer à l’enrichissement du secteur extérieur par un transfert de biomasse. La faible quantité de données récoltées dans les AMP pourrait être à l’origine des résultats négatifs. Ainsi, l’idée d'effectuer des suivis biologiques à court terme et d'analyser les indicateurs liés à la reproduction au niveau population ont été envisagés pour les trois AMP afin de trouver des résultats clairs quant à leur rôle dans la gestion des stocks halieutiquesThis thesis focuses on the study of the effectiveness of Marine Protected Areas (MPAs) as restoration tools of marine resources and fish stocks management in tropical West Africa. The study involves three MPAs. The first one is the Bamboung MPA, a marine reserve located in estuarine areas (with marine influence), closed to fishing since 2004. The second is the Urok Islands MPA established in 2005 and located in the biosphere Reserve of Bijagos archipelago in the coastal part of Guinea-Bissau. It is divided into three areas and fishing is allowed there with a fishing pressure becoming stronger from the central area to peripheral area. The third MPA is the Banc d‟Arguin National Marine Park located along the coast of Mauritania. It was created in 1976 and fishing activities are restricted. Many AMP were evaluated worldwide and the results are in the main part positive. In tropical zones, the variability of environmental parameters affects the spatial and temporal organization of fish assemblage. Therefore, the MPA establishment in a tropical zone has raised questions about their effectiveness inrelation to the influence of environmental parameters. According to the AMP, spatial or temporal approach will be used to answer questions. Comparison analysis will be used. The analysis of biological data comes after those of the physicochemical parameters that show strong seasonal variability in each MPA. This result justifies the choice of seasonal analysis of biological data in order to minimize the influence of environmental variations.Regarding the Bamboung MPA, the results of global approach clearly confirm that it is an effective tool for restoring marine resources. The seasonal approach shows this role in cold season, but not in hot and wet seasons. In 9 years of protection, the Bamboung MPA contributed to attract big fish in the Bamboung bolon. The spillover effect in Bamboung MPA is not clearly demonstrated according to our results. A downward trend of biological indicators according to the distance to the MPA has been observed especially in hot season and wet season. Similarly, the analysis of indicators related to reproduction does not show that the Bamboung MPA improve fish reproduction. Regarding Urok Islands MPA and Banc d’Arguin National marine Park, the results do not confirm that these AMP are fish stock management tools (improved yields of fishing activities and fish reproduction). However, for Urok islands MPA the observed trends suggest a biomass concentration in the central area, an equilibrium role played by the intermediate area and a role of fish biomass provider of the peripheral area. For Banc d’Arguin National Marine Parc, the inside area seems to contribute to the enrichment of the external area by transferring fish biomass. Non-specific results could be explained by the small data collected in the MPAs. So the idea to conduct a short-term biological monitoring and to analyze reproduction indicators in population level has been considered for the three MPA to find clear results on their role in the management of fish stocks

Full textAbstract:
Problems of scale abound in the science, governance, and conservation planning of complex social-ecological systems. In systematic conservation planning processes, which aim to effectively and efficiently allocate conservation interventions in space and time, nearly half of the stages in the planning framework involve decisions directly related to scale. The implications of scale-related problems are still poorly understood by conservation planners and researchers, as well as approaches to deal with these problems and integrate explicit multiscale thinking into the planning process. Thus, the overall goal of this thesis is to improve understanding of the different influences of scale on conservation planning outcomes, with the ultimate goal of making specific recommendations to improve the conservation planning framework to deal with scale more explicitly. As such, the structure of this thesis mirrors the relevant stages in the planning framework that involve scale-explicit decisions, organized by the two groups of scale considerations: technical versus practical.
The first research objective of my thesis seeks to understand the extent to which technical aspects of setting spatial priorities for marine conservation ('spatial prioritisations') influence where priorities are determined, and how this relates to conservation strategies that rely on broad, coarse-resolution prioritisations to guide the locations of finer-resolution priorities are actions. I address this objective in Chapter 2 by quantifying the individual and interacting effects of three prioritisation factors on spatial priorities for marine conservation: (1) planning-unit size, (2) thematic resolution of coral reef classes, and (3) spatial variability of socioeconomic costs. I used Fiji and Micronesia as case studies and found that all three factors influenced spatial priorities to different extents, with the spatial variability of socioeconomic costs having the largest influence, followed by planning-unit size and thematic resolution of reef classes. Furthermore, I identified an interaction effect between the thematic resolution of reef classes and the socioeconomic cost data used. These findings have important implications for the strategy of relying on coarse-resolution prioritisations to guide finer-resolution assessments and invalidate a number of implicit assumptions that are made when adopting such strategy.
Progressing to practical considerations of scale, my second research objective seeks to investigate the implications of another strategy commonly assumed or proposed to overcome scale mismatches between regional and local perspectives: dynamically iterating between regionalextent planning and locally applied actions ('iterative planning'), as conservation plans are incrementally implemented across a region. To address this objective in Chapter 3, I specifically explore how frequently regional priorities should be updated as local actions are gradually implemented. Using Fiji as a case study region, I found that changes in the frequency of updating regional priorities did not influence the total time taken to achieve conservation objectives, or the total extent of final reserve systems. However, I did identify two potential benefits to updating priorities more frequently: faster achievement of objectives for high-priority features, and greater potential to capitalise on areas that have previously had conservation efforts applied. This work provides insights into trade-offs to consider regarding the frequency of updating regional conservation assessments, which vary depending on specific planning contexts.
My third research objective seeks to determine if there is an optimal scale at which to conduct conservation planning, as a precursor to understanding how best to integrate planning across multiple scales ('multiscale conservation planning'). I address this in Chapter 4 by elucidating the respective strengths and weaknesses of conservation plans developed at different jurisdictional levels in the Coral Triangle region (e.g., local, national) to adequately consider multiple social and ecological scales. I found that no plans I assessed were able to adequately address all social and ecological scales, and that plans generally best addressed social and ecological components representative of the same level at which the plan was developed. This research adds nuanced appreciation of the limitations of lower- versus higher-level conservation planning. While these respective limitations are understood as the general inability to consider components at other scales, I demonstrate that these limitations can be attributed to differences in technical versus conceptual abilities. My findings demonstrate the necessity for vertical integration between planning levels as a means to overcome their respective limitations.
The fourth and final research objective of my thesis seeks to investigate the concept of multiscale conservation planning. It is overwhelmingly evident that the consideration and understanding of any social and ecological system must consider multiple scales explicitly. Thus, my thesis culminates in Chapter 5 with a theoretical and empirical examination of what it might mean to conduct multiscale conservation planning, a critical frontier in this field. Using Papua New Guinea and the Solomon Islands as case studies, I provide empirical evidence that refutes the conventional notion that conservation planning across multiple scales occurs unidirectionally ('scaling up' versus 'scaling down') and present a novel archetype that more realistically reflects multiscale planning in practice: 'multidirectional scaling'. I also evaluate factors that impeded or facilitated successful outcomes across multiple scales and reveal six scale-explicit characteristics for effective multiscale planning, the first two of which are novel concepts to the literature: (1) multiscale understanding, (2) scale jumping, (3) leadership characteristics, (4) stakeholder engagement, (5) policy frameworks, and (6) institutional settings. I propose these six characteristics constitute a new form of conservation capital, 'scalar capital', as a necessary resource or investment for successful outcomes across multiple scales.
My thesis contributes nuanced understanding of the sensitivities of the conservation planning framework to aspects of scale, in both theory and practice. I offer specific recommendations for each of the relevant stages in the conservation planning framework that involve scale-explicit concerns and illuminate some implications of existing problems and influences of scale. Essentially, it is the aim of my thesis to conduct research that can enable conservation practitioners to consider aspects of scale more explicitly and improve the efficacy of conservation planning outcomes. Conservation planning in practice must progress to view any system to manage and govern as inherently complex and multiscale; similarly, planning processes across multiple scales should adopt a 'planning system identity' (such as in complex systems) to correspond in design with the systems that they seek to manage.

Full textAbstract:
The paper gives an overview of the research project SBC (contract n° GIRD-CT-2000-03007), aimed at the environment protection and rehabilitation, by means of an innovative robotic equipment, purposely developed with active interaction between academia and industries, showing joint issues as for scientific, technological, economic, social and cultural aspects, along the challenging track to eco-consistency. The falls-off bring forth:- a new technology: the sub-bottom wire cutting; - a reliably tailored set-up: the robotic platform; - a low-impact duty-scheme: the dig-and-saw process; - a safe work-cycle: the remote monitoring and control. The Sub Bottom Cutter, SBC, approach grants highly conservative decommissioning operations of dismissed submerged offshore structures. Due to surrounding hostility (pressure, temperature, pollution, ...), the robot is remotely controlled from the surface, where a human operator monitors the task advance intervening if any snag occurs. The equipment uses the diamond wire technology (DWT) to cut the pile foundations beneath the sea bottom. The result is the full removal of the structure, which may be made by steel, concrete or a combination of the two, and the consequent restoration of the underwater environment, according to the enacted laws and regulations. The project originality relies on combining and improving known and co-operating technologies, namely: diamond wire cutting and sub-bottom operation; robot-based tools and remote monitoring and control. This leads to the never attempted task of shearing below sea bottom in a hostile environment by a low-impact duty-scheme (dig-and-saw), through reliable and safe process (unmanned work-cycles). The prospected technique allows the environmentally safe disposal of offshore installations (wellheads, platforms, terminals and sea-lines), as well as marine and harbour structures, limiting the volume of the seabed excavation to less than 10 m3 per each access to the structure to be cut, like, jacket piles or wellheads, etc.. The excavated volume of the solid materials per single dig is estimated to be 100–150 times less than the one removed by conventional dredge systems. Moreover, sub-bottom diamond wire cutting leaves mainly unaltered the surroundings, with most of metal discharges trapped at the operation site. The project was successfully fulfilled, and a prototypal equipment has been tested during July 2003, within a marine surroundings, properly accomplishing the cutting sequence. The paper presents an overall discussion of the technical background required by the case peculiarities, and summarises the main design incumbents faced for the ideation and the construction of the robotic platform. Emphasis equally focuses on the structural checks and on the work-cycle performance, with due account of the task specification, the prototype definition, the conditioning computational and experimental checks and the basic monitoring and overseeing environment asuuring reliable remote govern. The key benefits of the finally achieved prototype show the very relevant outcomes of the solution, such as: the use of a clean process, not interfering with the equilibrium of the marine habitat; the integrated design of mechanics, hydraulics and the underwater functional components; the unmanned operation, ruled by an intelligent remote control/drive station on surface; the guarantee of the completion of the cutting task, provided by remote monitoring; the previous assessment of life-cycle performance, by digital prototyping and virtual testing; the optimisation in terms of environmental impact, overall efficiency and system reliability for the use underwater, and the low energy consumption in relation to the total power applied (250/300 kW); the unaltered overall efficiency of removed structures and materials characteristics involved in the cutting process, thus allowing the re-use for the same or different work-scopes; the noteworthy efficiency of the dig-and-saw process, and the comparative low over-all costs. The presentation offers a noteworthy example where the integrated desing grants the successful merging of technologies, to efficiently and reliably fulfill demanding duties. The demand to restore uncontaminated conditions of marine sites modified by men activity and the global spreading of off-shore reclamation tasks require international concern, as, today, proper technologies are missing as for human and for environment safety. The urgency follows, in view of the European sustainability programmes and the North Sea case. In such a context, the prospected development could be winning reference.
