摘要:International Maritime Organization Maritime Safety Committee, at its 91 session on November 2012, adopted draft amendment to SOLAS regulation II-1/3-12, which changes the Code on noise levels on board ships from non-mandatory to mandatory. This paper provides optimizing process for ship noise in the accommodation space on the basis of results of noise analysis using SEA models of a certain oil tanker of 6,500 kiloliters actually constructed by a shipyard. In this regard, the authors identified how hull structure should be arranged and how noise control measures should be applied in order to reduce the target ship's noise levels efficiently by using generally useful optimizing process..
