Sea-fastening Analysis for Semisubmersible Vessel Based on Short-term Prediction of Motion Response
A new evaluation method of cargo fastening scheme based on short term prediction of wave motion response was proposed.According to the CCS Guidelines for Preparation of Semisubmersible Vessel Transportation Manual,the design wave height,wind speed and spectrum peak period range were determined for a particular route of a semi-submersible vessel carrying heavy cargo in single transport.The most probable maximum extreme responses in wave were predicted in way of short-term pre-diction.According to the predicted extreme value,the load of the cargo was calculated,and the anti-sliding and anti-overturning ability of the fastening scheme was analyzed.
