Abstract

This paper presents overview of existing seakeeping criteria for ship speed calculation in rough weather, applicable for large container ships. Sea states describing rough weather are given for North Atlantic sea environment according to the IACS recommendation Note No.34. Criteria are calculated for different ship responses in short-term sea states based on the response amplitude operators (RAO). 3D panel method is employed for computation of RAOs, while 2-P Pierson–Moskowitz wave spectrum is used for short term spectral analysis. Seakeeping criteria considered in the study are slamming, deck wetness, and vertical acceleration at bow. Sustainable ship speed is determined as combination of selected criteria and it is presented in polar plot diagrams for representative sea states. Practical overview how seamen feel operational criteria and which is sustainable speed in real life is also presented. In the conclusion, critical assessment of criteria is performed and guidelines for future research are provided.
