半潜船 meaning in Chinese

near surface ship
semi-submerged ship
semi-submersible vessel

With a rig on board , the semi - submersible heavy lift vessel has a very high center of gravity , poor stability and is easily damaged by wave and wind
半潜船装载海洋平台后，重心高，稳性差，易受风浪打击。
Farther more , feasibility analysis will be done for every transporting , even for the same heavy lift vessel because styles and weights of different rigs are so different
同时，海洋平台本身种类繁多，尺寸和重量差别悬殊，因此，即使对于同一艘半潜船，只要装载不同的海洋平台，就需要分别进行可行性分析。
In this paper the characters of rig and heavy lift vessel , the transportation market of rig and heavy - lift vessel operation are introduced ; the process and content of the feasibility analysis of rig transportation using heavy - lift vessel are described ; the metocean database imdss and the strip theory used in feasibility analysis are introduced and evaluated
本文介绍了海洋平台的特点和海洋平台运输市场的情况；半潜船的特点以及用半潜船运输海洋平台的载运工程的过程。探讨了半潜船运输钻井平台可行性分析的方法和内容，提出并评价了可行性分析中用到的遭遇风浪数据库imdss 、波浪理论、切片法等技术。
