CSP - The 13th international conderence on the stability of ships and ocean vehicles and 7th international maritime conference on Design For Safety
Abstract
Stability, which is an ability to prevent capsizing of a floating body, is one of the mostfundamental element s in ship design, and can be regarded as unique in naval architecturefor many years since the days of Archimedes (circa 250 BC). Although our knowledge anddesign tools for ship motions in waves were almost sufficiently improved mainly based onlinear theories, the stability issues still remain as hot research topics to be scientificallyresolved because of its inherent nature of nonlinearity. STAB (international conference onthe stability of ships and ocean vehicles) launched possibly under this demand in 1975 inGlasgow and then its second conference was held in 1982 in Tokyo. These conferencescontributed very much to the development of weather criterion, to supplement pureempirical ship stability criteria, with researchers, designers and so on. In 2018 the stabilityconference will revisit Japan. During these 43 years, the stability conferences continuouslyfacilitate ship stability criteria developments for intact and damage ships at theInternational Maritime Organisation (IMO) and novel ship designs all over the world.STAB2018 is expected to provide scientific and practical bases for discussing new stabilitycriteria such as risk-based and/or physics-based ones and their applications to innovativeships and ocean vehicles.The concept of the "Design for Safety" has been advocated among IMO and EuropeanCountries and continues to gain momentum. The key issue is to address ship safety costeffectively.Here, safety is not treated as a design constraint and a limiting factor of shipprofitability but as design objective aiming to enhance the value of the designed ship atthe competitive safety-conscious market.For promoting the theme "Design of Safety",DFS2018 (the 7th International Maritime Conference on Design for Safety) expectsparticipation and support by Administrations, Classification Societies, Universities,Research Institutes, Ship Design Offices, Shipbuilding and Shipping industries, Oil andGas and other industries with knowledge-intensive, safety-critical products from all overthe world to exchange the latest information and innovative ideas. The expected topics areframework on design for safety, methodology/application on design for safety, humanfactors, ship and system resilience, structural reliability, live saving approaches, big datafor improved safety.The invited speakers in these conferences are mainly two. First speaker is Ms. HeikeDeggim. She is a director of maritime safety division at International Maritime Organization(IMO). She will make a speech on the significance of new stability criteria. Another speakeris professor Alberto Francescutto from university of Trieste in Italy. He will make a speechon the research history of the new stability criteria.In these conferences, two proceedings will be provided, that is proceedings ofSTAB2018 and DFS2018. Every technical paper included in these proceedings is peerreviewedone. Furthermore, some superior papers are selected to be published in OceanEngineering which is one of the authoritative journal in this field.Naval ships in a lot of navies, as well as merchant ships, have been designed andoperated for the past 40 years in accordance with empirical stability criteria derived formonohull vessels of World War II. As a result, applicability of such empirical criteria tomodern ships, which are remarkably different from ships of World War II, is questionable.This means stability safety of modern ships is not rationally guaranteed with current levelof science and technology. In other words, the existing empirical criteria could discourageinnovative new ship design for avoiding potential danger of capsizing. Only one navy thathas been identified as applying physics-based stability criteria is the US Navy. Herecapsizing probability in ocean waves is directly calculated by a system-based simulationmodel, such as FREDYN. However, the capability of the simulation model for
