ON THE STUDY OF OPTIMAL DESIGN OF A ULCC UNDER RESTRICTED DRAUGHT

The pursuit of economy has resulted in large tankers, so-called VLCC or ULCC. Deeper draught is, of course, advantageous for the purpose of increasing the tanker size, but naturally it is not unlimited. In this paper, authors tried to survey through the simulation technique for the optimal dimensions of ULCC with respect to building cost under restricted draught which can stand against the conventional tankers free from draught restriction. Consequently, it was found that lower L/B makes building cost cheaper and that severer draught restriction makes this tendency notable. Reflecting the study, authors have developed the new design of 400,000 dwt ULCC with L/B as low as 5 and with restricted draught of 22.15 meters. And to materialize the design, authors have made an extensive feasibility study regarding controllability, propulsion and structure for hull using many sizes of models including a large model 30 meters long.
