摘要
冰区船舶船体结构受到冰载荷作用而产生应力,因此对冰带区域内结构需要进行加强设计。以我国首座适合北极海域的深水半潜式钻井平台为背景,对冰区航行的半潜式钻井平台船体结构计算作简要说明,研究最新冰区加强标准,并对平台的主船体结构加强设计进行相关研究。
The structure in ice environment should be strengthened because of ice loading influence.The characteristics of the semi-submersible offshore drilling platform intended to be navigated in ice environment are introduced.Some researches on criteria and the structure strengthening of the semi-submersible offshore drilling platform in ice environment are carried out base on the first semi-submersible offshore drilling platform designed by China.
