Progress in simulation-based ship design

Simulation-based ship design increasingly replaces traditional-based design.

Extensive experience gathered over the last ten years on this topic enables Germanischer Lloyd, as one of the world's leading technical supervisory organizations, to present various approaches and state-of-the-art at the Pacific 2008 trade fair. The presentation ''Progress in simulation-based design'' took place today at the Maritime Engineering Sydney Convention Centre, Darling Harbour. Ship designing processes are iterative, and subdivided into several phases during which the design is developed in increasing degrees of detail. In his presentation Karsten Fach, head of competence centre for engineering services at GL, focused on one basic activity in modern ship design: analysis. Germanischer Lloyd developed a numerical procedure based on the combined use of a boundary element method (BEM), a statistical analysis technique using random process theory, and an extended RANSE solver to obtain accurate responses of ships in a seaway. In simulations, forces exerted by the sea cause the vessel to move, exciting sloshing in the tanks. Extensive experience allows Germanischer Lloyd the numerical prediction of sloshing loads in ships with great confidence.
