摘要

应用有限元仿真技术,以我国南海使用的深水半潜式海洋钻井平台为原型建立模型,进行极限工况下波浪参数搜索工作. 依据 ABS ( American Bureau of Shipping ) 和 DNV ( Det Norske Veritas ) 规范,应用随机性设计波法搜索并确定深水半潜式平台两浮体之间分离力最大工况、纵向剪切力最大工况、绕横轴扭矩最大工况以及总纵垂向弯矩最大工况共四种极限工况下的波浪参数,并通过所得波浪参数计算平台表面载荷分布.

Abstract

Aiming at the south China sea semi-submersible platform, by using FEA simulate method,the wave parameters were studied in its extreme cases. According to ABS (American Bureau of Shipping) rules and DNV ( Det Norske Veritas) rules,the parameters of four extreme cases were searched and found by using stochastic method, such as case of the maximum rent force between buoyant hulls, case of the maximum fore-and-aft shear force, case of the maximum torsion and case of the maximum fore-and-aft vertical bending moment,which were used to calculate the surface loads distribution of this platform.
