This is a nice compilation of the proceedings of the papers that have been presented in the course of the Third ISSW and summary of discussions. One of the main objectives of that event was to promote the maximum possible exchange of technical information directly related to the research and developments in ship stability as well as operational safety.
This may be achieved through the in-depth discussions by the world respected experts. The first of the papers provides a sort of intro to the numerical modeling of the vessel motions and usage of such models in the analysis of the ship's intact stability. The author of the article has presented a good discussion of various important and actual aspects that shall form a part of the whole process of modeling, namely the ship system, environment, excitation and response, supplemented with a very brief overview of the techniques used for modeling of the hydrodynamic forces.
The main emphasis has been put on quality assurance and validation of various numerical modeling techniques. Among the topics that have been covered during that workshop there were application of various non-linear systems dynamics to vessel stability, numerical/physical modeling of intact/damage stability, some special ship stability problems etc.
RINA International Conference - Naval Submarines and Unmanned Underwater Vehicles - 2011. Topics discussed in the course of the conference - Towards an automated active unmanned underwater vehicles docks on a slowly moving submarines, a submarine concept design, underwater gliders, evaluation of the maneuvering performance of the x-plane submarines, hydrodynamic design implications for submarines operating close to the surface, United States submarine concept design tool, construction materials for small sized submarines, alternative propulsion options for nuclear underwater vehicles, and many more.
Let us start with the first one, dedicated to the development of the integrated SES (submarine escape systems) - it provides readers with the review of the tower escape systems, addresses the geometry and ergonomics of the tower, pressurization, flood and draining matters, testing, acceptance and further support. The submarine escape is considered the very latest resort in case of the underwater vehicle becoming fully disabled - though rescue is of course the preferred option in the majority of instances, it may not be possible in some cases. Here are the operation and acquisition requirements...
RINA International Conference - Warships 2009. This compilation contains of the selected interesting topics that were discussed in the course of the subject conference, for example Aircraft tie-down points for the affordable aircraft carrier - Introduction - Significance - Design approach - Cost savings - Meeting the requirements - Conclusions; Development, design of the rudders/propellers as well as hydrodynamic design of the aircraft carriers of Queen Elizabeth class; Optimizing the ship-air vehicle interface using the simulation method; Frigate aviation of the future; Real options reasoning in defense acquisition; The vessel design challenge of naval UAV (unmanned aerial vehicles).
The opening topic was dedicated to the development of the world famous aircraft carriers, meaning the ones belonging to the "Queen Elizabeth" class. The corresponding paper presented at the conference, provided the participants of the event with brief but thorough technical description of the key aspects of the advances involved, and also describes the associated alliance arrangements.
The shipbuilding strategy applied in that case did involved the construction of the big fully outlined blocks at different locations throughout the country; subject blocks were then transferred to Rosyth for assembly and integration...
Warships - RINA International Conference - 2006. The reporters addressed following interesting topics in the course of that international conference - modeling maritime and warship survivability, operational experience with Sea Fighter FSF1, design issues concerning the high-speed adaptable littoral warfare, power and propulsion for the new generation of global combatant, survivability of the warships, tools to reduce vulnerability at the earliest stages of the ship design, multipurpose versus modularity, some affordable ways of protection of vessel systems against fragments and blast, and many more... the publication opens with the article dedicated to the new family of warships by VT Shipbuilding.
The significant increase in the costs over last decades for both new construction and upgrades/modifications and retaining in active service of the destroyers and frigates have resulted in the problems that are currently experienced by many Navy fleets when maintaining adequate ship hull numbers to perform various assigned tasks. The approach that is currently used today, implying production of the multi-purpose vessels may appear too costly to address imminent problems of fleets becoming lower and lower over the next years...
The volume is a result of the collective efforts by the world leading and recognized experts in the industry, bringing together numerous valuable assorted contributions that were presented in the course of the OS-017, standing for the Ocean Science Session, and the Joint Assembly that were both held in Singapore some years back.
The chapters of the present publication are dealing with the modeling and the assessment of the dispersal communication incoming with SGD in the coastal areas affected by tsunami, numerical simulation applied to the coastal sediment transport by the earthquake tsunami which occurred in Tohoku-Oki in 2011, database of the tsunami events, raw/processed water level information, simulations of the tsunamis in the Western Pacific Ocean and in the East China Sea aroused from the earthquakes that took place along the Nankai-Suruga trough, various negative consequences of tsunamis on the ecosystem services, discussion related to the interaction of tsunami with fringing coral reef, effects of the wave erosion caused by tsunamis on the natural landscapes, concatenated hazards, floods, tropical cyclones and climate change, vertical evaluation system, contribution of the multiple wave arrivals to the duration of the tsunami and the damage caused, and so many other relevant and indeed critically important topics.
The series of international technical conferences held with the purpose of improvement of the Stability of Ships and Ocean Vehicles has been running since 1975, and, on behalf of the National Committee, I am very proud that Australia was chosen to host the 7th conference in February 2000.
The objectives of the present conference series is to promote a full exchange of methodologies and ideas related to the stability of ships as well as ocean vehicles. It creates practical opportunities to all marine industry pros, including ship constructors, naval architects, officers of the various certifying and inspection authorities, regulatory agencies, capsize prevention researchers, ship and platform owners, and others to present, discuss and listen to improvements in capsizing prevention for all sizes and types of floating structures.
The most important aspect of any floating object is its ability to remain afloat and upright under all expected conditions. Even this most basic of requirements can elude professionals in the field, usually with very serious consequences. It is therefore vital that all of us who are concerned with the operation and design of ships and ocean vehicles devote the utmost effort to ensuring they are as safe as possible. Only by sharing knowledge and experience can we continue to improve safety, which is the primary motivation for this important conference series.
The present paper provides all interested parties with some brief description of the work the IMO has undertaken in respect of development of the international requirements and recommendations on intact/damage stability for various types of ships during the period 1990-1994. This paper also includes a brief account of the current works on this subject within the Sub-Committee on Stability and Load Lines and on Fishing Vessels Safety which is the IMO's body responsible for the activities of this Organization in the subject area.
The IMO was founded by the UN Conference held in Geneva in 1946. In 1958 the Organization came into being as the only UN specialized agency solely concerned with maritime affairs. The establishment of IMO was initiated by the recognition of fact that, because of the international nature of the maritime industry, it is only through concerted efforts of States, co-ordinated on an international level, that action to enhance safety at sea would be much more effective, and that a permanent body coordinating and promoting further measures leading to a more continuing basis would serve well the cause of maritime safety.
The main objective of IMO is to facilitate co-operation among governments in technical matters affecting shipping in order to achieve the highest practically possible standards of maritime safety and navigation. since 1967, the Organization has given special emphasis to issues of pollution prevention of sea from ships and to legal matters associated with its technical work...
One of the main purposes of the Organization consists of promoting the highest practical standards of maritime safety and navigation, and the Sub-Committee on Stability and Load Lines and on Fishing Vessels Safety in its current, as well as in its previous, work undertakes all possible effort to incorporate the latest achievements related to both design and theoretical areas into its existing standards as well as in regulations actually being developed.
So far, intact stability requirements and recommendations have been developed for passenger ships, cargo ships, fishing vessels, dynamically supported craft, MODUs, offshore supply vessels, special purpose ships and sea-going pontoons, thus covering the overwhelming majority of the world's merchant fleet. Standards of damage stability were introduced for the first time for passenger ships in the 1948 SOLAS Convention and re-adopted by the 1960 and 1974 SOLAS Conventions. For some specific categories of ships, such as tankers, chemical tankers and gas carriers, IMO developed sets of requirements and recommendations based on the principle of prevention of massive spillage of their cargo into the sea; the current "state of the art" for other types of vessels has been given below.
The detailed description or IMO's activities related to the development of stability standards within the period 1962 to 1986 was given in papers presented at the Second and Third International Conferences on Stability of Ships and Ocean Vehicles held in 1982 in Tokyo and in 1986 in Gdansk, respectively. This paper summarizes the progress achieved by the SLF Sub-Committee since 1986...
