Abstract:
Securing a ship’s safe stability is essential. Thus, monitoring the stability parameters of the IMO requirements is required to provide an alert about the risk of the safety of ships’ stability to the captain, officers, and the crew of a ship. However, calculating all ships’ intact stability parameters is complex without ship loading software or equipment. To evaluate ships’ intact stability parameters, a convenient methodology to simply calculate them is necessary as a supplementary method for ships in the absence of loading software or equipment. In the present study, the Simple Evaluation Methodology for Intact Stability (SEMIS) is proposed. SEMIS is introduced for simply evaluating the safety of ships’ stability according to GM. Based on the stability parameters of 336 loading conditions of 19 model ships, empirical formulas of SEMIS are derived. To verify the proposed methodology, the stability parameters of two model ships in 28 loading conditions are calculated using the proposed empirical formulas and the principal calculation methods, respectively, and then compared. The developed SEMIS efficiently evaluates the ships’ stability using only GM.

Abstract:
Abstract Suspension ships are a novel type of ships that utilize a suspension system as an integral part of their structure. One critical aspect of a suspension ship is its stability characteristics. The parameters that affect the initial transverse stability of these ships include the ship’s mass ratio, loaded height of suspension, placement location height of suspension, and beam. It is found that designing a suspension ship in monohull configuration is more difficult than in a catamaran configuration. Special attention is required when the static mass ratio is below 2 for both monohulls and catamarans.

Abstract:
Wind sailing boat fades out maritime transport industry gradually, because of its existence decreases the ship stability, and threatens mariners and ships security vastly. Project group has worked out high stability and security ship through researching literature and emulation-technique. Through the design of a parent ship and a sub-shipa set of wind sailing system and a water supply and drainage system, and the modeling calculation and analysis about the thrust of the fixed pitch propeller matching with the sailing, we can conclude that the added sub-ships can enhance ships stability in constant speed sailing situation. So it can improve thrust and reduce fuel consumption through increasing the scale of wind sailing.

Abstract:
Capsizing accidents are regarded as marine accidents with a high rate of casualties per accident. Approximately 89% of all such accidents involve small ships (vessels with gross tonnage of less than 10 tons). Stability calculations are critical for assessing the risk of capsizing incidents and evaluating a ship’s seaworthiness. Despite the high frequency of capsizing accidents involving them, small ships are generally exempt from adhering to stability regulations, thus remaining systemically exposed to the risk of capsizing. Moreover, the absence of essential design documents complicates direct ship stability calculations. This study utilizes hull form feature data—obtained from the general arrangement of small ships—as input for a deep learning model. The model is structured as a multilayer neural network and aims to infer hydrostatic curves, which are required data for stability calculations.

Abstract:
To evaluate the safety of passenger ships’ stability, ten stability parameters should be calculated. However, since the process for calculating all stability parameters is complex without a ship loading program, a convenient methodology to simply calculate them and evaluate the safety condition of a passenger ship is required to alert the hazard to a captain, officer, and crew. The Index for Passenger Ship Intact Stability Appraisal Module (IPSAM) is proposed herein. According to the value of a passenger ship’s metacentric height (GM) which could be calculated by the ship’s roll period measured by sensors in real-time, IPSAM simply calculates nine intact stability parameters except for AnglemaxGZ and proposes the present stability status as a Single Intact Stability Index (SISI). It helps crews easily recognize the safety of passenger ships’ stability as a decision support system in real-time. Based on the intact stability parameters of 331 loading conditions of 11 passenger ships, empirical formulas for IPSAM were derived. To verify the empirical formulas of IPSAM, the stability parameters of a passenger ship in 20 loading conditions were calculated using proposed empirical formulas and the principal calculation methods respectively, then compared. Additionally, the result of the SISI of 20 loading conditions successfully indicates the danger as the value of the SISI under 1.0 of the three loading conditions that do not satisfy the IMO intact stability requirements.

Abstract:
Along development of technology from time to time, makes the shipping sector have experienced development. This made the Indonesian geverment place the maritime sector into a priority program in national development. The development of ships occur from various scopes, this things takes the development of ships in terms of the number of hulls such as single hull (monohull), double hull (catamaran), and with three hulls (trimaran). This research uses a literature method that will analyze the results of previous research related to the ship’s performance. The purpose of this research to determine the best performance between ships with monohull, catamaran and also trimaran forms. The results of this research are expected to be a basic reference for selecting the ship’s hull to be fabricated in the future, whether in terms of tourism, military, etc. the results of this research indicate in terms of stability ships with trimaran hulls have good stability among others. This is because trimaran ships have a larger surface area than monohull and catamaran. With the ratio of the width and height of the ship makes the catamaran have good stability. In terms of resistance, catamaran ships have the smallest resistance than others, but this influenced by the demihull distance factor which makes the waves formed from each hull not collide with each other. In terms of seakeeping, the catamaran is the best in case of heaving, rolling and pitching conditions from all heading angles.

Abstract:
The paper examines the intact stability of historic passenger ships from the point of view of the contemporary notion of the intact stability, i.e. the Second Generation Intact Stability Criteria (SGISC) framework. An intact stability assessment using the Vulnerability Level 2 calculation procedures of SGISC for the dead ship condition was performed on four ocean liners: RMS Titanic, RMS Queen Mary, SS United States and SS Michelangelo, and two cruise ships: MS Song of America and MS Costa Concordia. In addition, the intact stability of the selected ships was appraised using the present-day mandatory intact stability requirements contained in the 2008 Intact Stability Code. The selected ships are believed to be good representatives of the main trends in passenger ship design over a one-hundred-year span bounded by two well-known maritime catastrophes: the sinking of the Titanic in 1912 and the Costa Concordia disaster in 2012. The paper offers an insight into how major design changes have affected the intact stability properties of passenger ships over this period. It was found that the examined ocean liners would perform well in terms of intact stability in the dead ship condition even from the point of view of the SGISC. The analysis also confirmed the advantages of the approach using the SGISC framework over simplified, (semi)empirical stability assessment methods. By looking into the evolution of the intact stability of ocean liners and cruise ships from the contemporary perspective, the paper draws the conclusions which are considered useful for the design of future passenger ships.

Abstract:
Ship’s stability is one among the foremost important and complicated concept regarding ship and navigation’s safety and it's governed by maritime law as well as maritime codes. In Albanian bays, there has been considerable maritime tourism development in recent years, which has consequently brought about an increasing demand for passenger ships offering mainly one day cruises. The ships intended for this type of service are of different typologies: tourist vessels built especially for this destination, but there are many vessels which have changed the destination mainly from fishing vessel to tourist vessel. From the field observations along with contacts with the port authorities and Albanian maritime administration, it is revealed that these ships bare problems related to meeting service and security standards that they offer. Considering existence of such problems and the absence of technical data related to the safety of ships, it is required that geometric and stability calculations are performed with the view meeting the norms of stability. In this paper we will be presenting the causes that lead to ship stability failure and their impact on navigation safety. A case study of the calculation of the ship stability is going to be presented, the causes are going to be analysed and the possible ways of stability failures are going to be assessed. Vessel’s intact stability is a fundamental component of seaworthiness so it's in the interest of all owners/operators to be aware of this subject and make sure that their vessel has a satisfactory level of stability in order to ensure its safety as well as that of people on board.

Abstract:
The initial stability of a ship is currently evaluated by empirical formula based largely on a static approach. Evidently stability is affected by speed that causes variation of pressure distribution on the wetted surface of a ship's hull, and generated waves on the surface of water by the vessel's motion. Forces and moments resulting from bottom pressures, as the speed of the ship changes, are significantly different for the ship at rest and in a seaway. The principal aim of the research is to investigate the effect of variations of forward speed on stability of a ship in calm water. The thesis presents theoretical and experimental approaches of the research. The novelty of the research results leads to the conclusion that although increasing speed may improve the stability of a ship in some cases, it also depends on heeling angle or on any asymmetry of the wetted area of a hull. Taking into account asymmetry effects, unbalanced pressure distribution acting on the wetted surface of the hull, in some cases, hence, decrease of stability is also possible. On a moving, partially immersed body, hydrodynamic and hydrostatic forces predominate. These forces arise owing to interaction between the body's motion and its weight with respect to the surrounding water. In order to calculate these forces, the panel method of Computational Fluid Dynamics (CFD) has been applied to identify the velocity and pressure distribution on the wetted surface of a ship's hull. The mathematical model adopted is based on the source distribution on the ship's hull, known as the Kelvin source. The model for a body travelling with steady forward speed, where its motion does not disturb the free surface, is known as double body theory. For consideration of waves generated by the motion of the ship on the free surface, a three dimensional linearised potential flow solution has been utilised. Comprehensive tests conducted in the UCL towing tank have established a better understanding of the significance of variation of ship's stability associated with forward speed in calm water. It is shown that an accurate judgement regarding the ship's stability cannot be made if only the effect of forward speed, as a single parameter, is considered. The heeling angle is another important parameter that must also be taken into account. The effects of a combination of both variables have been investigated, and are reported herein. The research is presented showing that the applied CFD method may be developed as an alternative method to assess stability of a ship in seaway, but there is a long way for the CFD approach to replace towing tank testing. At present, CFD may be used for consideration as a precursor to improve ship's stability during the design stage, for modification, and before operation. It is hoped that in future the findings of the experimental approach of this form of research could be used as additional guidance to be incorporated within the stability documentation for individual ships at the design stage, and ship trials.

Abstract:
Motions and stability of a typical B.C. fishing vessel were experimentally and numerically investigated in a longitudinal seaway condition. The experimental model was self-propelled, radio-controlled and equipped with an on-board data acquisition system. Pitch, roll, yaw, surge, and heave responses to regular waves of predetermined frequencies and amplitudes generated along a 220-ft model basin were obtained. Different displacement conditions and GM configurations were tested. The numerical model for the dynamic analysis of the fishing vessel motions has been implemented using strip theory. A computer program was developed to study the nonlinear motions of the vessel. The velocity dependent coupling terms, responsible for a major part of the nonlinear behavior, were included. A time dependent component analysis of the roll damping has been performed. Regular linear and nonlinear waves were used. A parametric study of the fishing vessel stability has been carried out by considering its dynamic response in waves of varying characteristics. Unstable behaviour was found to be closely related to waves of length of similar magnitude to the ship length. The effects of wave amplitude and rudder usage were found to be of capital importance in the capsizing process. Experimental and numerical results showed good agreement.

Abstract:
This Master of Science thesis was written based on the shipbuilder Kockums AB feasibility study regarding the development of an All- Electric Ship for the Swedish Navy. The thesis was aiming at addressing voltage stability issues in a dc system fed by PWM rectifiers operating in parallel when supplying constant power loads. A basic computer model was developed for investigating the influence from various parameters on the system. It was shown that the voltage stability is dependent upon the ability to store energy in large capacitors. It was also shown that a voltage droop must be implemented maintaining load sharing within acceptable limits. Different cases of operation were modelled, faults were discussed, and the principal behaviour of the system during a short-circuit was investigated. It was shown that the short-circuit current is much more limited in this type of system in comparison to an ac system. It was concluded that more research and development regarding the components of the system must be performed.

Abstract:
There currently exists no direct method for predicting the righting energy of a ship based on key geometric hull properties. Consequently, naval architects traditionally select hull parameters based on other constraints and merely check the dynamic stability indicators after designing the preliminary body plan. Quantifying these relationships would allow such indicators to be used as design variables in optimizing a hull form. Additionally, the hull form has a considerable impact on ship motion theory and dynamic stability criteria. This thesis suggests possible functional relationships, to predict the residuary stability of a design using basic hull parameters

Abstract:
AbstractThe stability of ship lift chamber operation has always been the key factor restricting the development of ship lift, which has not been well solved for a long time. With the development of upsizing of ships, the super-huge fully balanced ship lift with hoisting steel wire rope over 10000–15000 t is the development trend in the future. The mechanism of water loss and capsizing of multi-point ship lift is the most key scientific problem, and the most core technical problem is the layout and operation control of ship lift system. A generalized physical model of ship lift with the model scale of 1:33 was established to study the influence of multiple factors on water loss stability of ship chamber, such as gravity counterweight/torque counterweight ratio, water leakage flow, the position of suspension points among the chamber, quantity of the suspension points, and so on. Secondly, the structural dynamics equations of hoisting system is deduced in detail, considering the water fluctuation in the process of water loss caused by longitudinal capsizing moment influence on balance system, and research on the transient dynamic characteristics of hoisting system of the filtration process, determine the ship chamber conditions of stability for the trim through the Lyapunov stability criterion. The optimization calculation model of ship lift mechanical suspension system layout under the action of multiple constraints was established, and the effective measures will be given to improve the pitch stability. The results can provide technical guidance for the upsizing of ship lifters.

Abstract:
New minimum intact stability criteria are presented to ensure safety against capsizing invoked by sudden loss of crane load during heavy lifts at sea, followed by typical sample stability assessments for a lifting operation on four multipurpose ships. For added stability, two of these ships had a pontoon attached at their sides opposite the lift. Two numerical time-domain methods assessed the transient dynamic heel after a sudden loss of crane load. With the ship at equilibrium, both analyses started by releasing the crane load, simulating a sudden failure of the lifting gear. The first method solved the roll motion equation as a one-degree-of-freedom system; the second method used a Reynolds-averaged Navier-Stokes equations solver. The first method relied on appropriately chosen linearized roll damping coefficients, and the nonlinearity of the righting moment function had to be accounted for. The second method required creating extensive numerical grids to idealize the ship’s hull, including the counter balancing stability pontoon, rudder and bilge keels, as well as all parts of the ship’s superstructure that effect the righting moment at large heeling angles.

Abstract:
The new probabilistic and more risk based subdivision and damage stability rules have brought many changes and more flexibility to the subdivision requirements for passenger ship designs. Whilst designers are still adapting to the fundamentally changed SOLAS requirements, applicable January 1st 2009, many additional items remain on the agenda of IMO addressing the stability of passenger ships. Additional damage stability regulations for ro-ro passenger ships as well as requirements towards stability and sea-keeping characteristics of damaged passenger ships in a seaway when returning to port by own power or under tow are among the topics that are currently being addressed. These could have considerable impact on future passenger- and ro-ro passenger vessel designs.

Abstract:
In 1996, the 22nd ITTC formed a Specialist Committee on Ship Stability. There were two main mandates given to this committee. Toe first was to examine the techniques for carrying out model experiments used to investigate the capsize of intact and damaged ships and provide guidelines for carrying out these experiments. Toe second was to assess the methods available for numerical simulations of the capsize of intact and damaged ships. This paper describes the findings of the committee so far, at the end of its second year of a three year term. The committee has prepared a summary of the state of art in the areas of numerical and physical modeling of intact and damaged ships. It has also circulated a questionnaire concerning the type of numerical methods used by ITTC member organizations for predicting the capsize of intact and damaged ships. Another major objective of the committee is to 'benchmark' codes against a standard hull form, for which there are well documented experiments. The hull form chosen was a container ship tested at Osaka University. This paper provides a brief summary of the findings of the committee in each of the four subject areas and makes recommendations for standard model test methods for intact and damage capsize predictions. It also discusses the preliminary findings from the questionnaire.

Abstract:
Current damage stability rules for ships are based on the evaluation of a ship’s residual stability in the final flooding stage. The consideration of the dynamic propagation of water within the inner subdivision as well as intermediate flooding stages and their influence on the resulting stability is very limited in the current damage stability regulations. The investigation of accidents like the one of the Estonia or the European Gateway reveals that intermediate stages of flooding and the dynamic flooding sequence result in significant fluid shifting moments which have a major influence on the time-dependent stability of damaged ships. Consequently, the critical intermediate stages should be considered when evaluating designs with large cargo decks like RoRo vessels, RoPax vessels and car carriers. Also the safety of large passenger ships with respect to damage stability is affected by the aforementioned effects. In this context a new numerical flooding simulation tool has been developed which allows an evaluation of a ship’s time-dependent damage stability including all intermediate stages of flooding. The simulation model is based on a quasi-static approach in the time domain with a hydraulic model for the fluxes to ease the computation and allow for fast and efficient evaluation within the early design stage of the vessel. This allows studying multiple damage scenarios within a short period. For the further validation of this numerical simulation method a series of model tests has been particularly set up to analyse the time-dependent damage stability of a floating body. The test-body has been designed specifically to reflect the most typical internal subdivision layouts of ships affected by the effects mentioned above. The experimental study covers a static model test series as well a dynamic one. The static model test series has been set up with the aim to analyse the progressive flooding of selected compartments in calm water. Within the dynamic model test series, the model is excited by a roll motion oscillator to evaluate the influence of the ship motion on the water propagation and the associated damage stability. The model tests presented in this paper comprise side leaks in typical compartments which are used for a basic validation of the simulation toll and the measurement devices. Particular attention has been drawn on damage scenarios with critical intermediate flooding stages in consequence of restricted water propagation. The presented results enable a further validation of the numerical flooding simulation and give an insight view on the chosen experimental setup.

Abstract:
The new probabilistic damaged stability regulations for dry cargo and passenger ships (SOLAS 2009), which entered into force on January 1, 2009, represent a major step forward in achieving an improved safety standard through the rationalization and harmonization of damaged stability requirements. There are, however, serious concerns regarding the adopted formulation for the calculation of the survival probability of passenger ships and the associated required subdivision indices, particularly for RoPax and large cruise ships. The present paper outlines the objectives, the methodology of work and main results of the EU-funded FP7 project GOALDS (Goal Based Damage Stability, 2009-2012), which aims to address the above shortcomings by formulating a new rational, goalbased regulatory framework, properly accounting for the damage stability properties of passenger ships and the risk to people onboard.
