Abstract: This paper summarises the most important aspects of shipping today, describingstakeholders, markets and types of ships, and weighing the sustainability of this form oftransportation. Furthermore, it follows an initial ship design project step by step: a new vessel is beingprojected to fulfill a transportation need. The vessel will safely and cost-effectively transport1.2 million cubic meters of raw logs from Port Metro in Vancouver to the Chinese harboursTianjin and Qingdao. During the initial design phase, the requirements and main limitingfactors of the ship’s specifications are identified and the system concept is created. Also investigated in this paper is the need for a new generation of intact stability criteria forships, in light of the mechanics of a stability failure mode, parametric rolling, and cases ofparticular accidents at sea involving parametric rolling. The circumstances surroundingincidents of stability failure in cases where existing criteria are met, are explored. The existingcriteria are examined and possible motivations behind the development of new criteria areconsidered. Finally, new methods for assessing risk in the case of parametric rolling areproposed. Based on the importance of this topic for safety at sea, and the hypothesis that asecond generation of stability criteria is needed is examined critically.
