某1000t打捞起重船坐底强度有限元分析

Bottoming Strength Calculation for 1000 t Salvage Lifting Ship

目前国内对海洋工程船舶的坐底强度的分析较少。随着海洋行业的快速发展,越来越多的海洋工程船舶因作业环境及作业范围的提高需要进行坐底,尤其对于某些特殊的浅滩作业。本文对一艘具有坐底功能的打捞起重船的船体强度进行计算分析,综合考虑风、浪、流等环境载荷组合以及起重机载荷在坐底工况下对船体强度的影响,利用MSC-PATRAN有限元通用软件,为该类型船舶的坐底强度计算提供计算参考。

At present,the ship bottoming strength analysis is aimed at offshore platforms,and there is less bottoming strength analysis of offshore engineering ship.With the rapid development of domestic marine industry,more and more marine engineering ships need to bottom on the seabed due to the improvement of operation scope and the working environment,especially for some special shoal operations.In this paper,the hull strength of a salvage lifting ship with bottoming function is calculated and analyzed with the MSC-PATRAN finite element general software,considering the combination of environmental loads such as wind,wave and current and the influence of lifting load on hull strength under bottomed condition.
