维修型半潜船推进器辅助锚泊定位能力分析

Research on thruster assisted anchoring positioning in semi-submerged maintenance ship

为了提升半潜船在定位作业能力,提高抗更恶劣的海况,本文通过对半潜船的锚系泊定位能力进行优化,采用海洋平台、FPSO等海洋工程中的推进器辅助锚泊定位系统的技术和经验,应用于半潜船设计中,以满足半潜船应急定位需求。通过动力定位计算,提供推进器辅助定位,着重比较半潜船在动力定位辅助下,锚泊定位能力的提升效果,可在更大海上风浪流环境条件下的进行锚泊定位,以满足突发的高海况应急定位控船之需。

The purpose of this paper is to use the experience and technology of propeller assisted mooring positioning system in offshore engineering such as offshore platform and FPSO to design semi-submerged maintenance ship,so as to promote the ability of mooring positioning system against more adverse sea condition.Through the capability analysis of dynamic positioning and the research of joint system control for semi-submerged maintenance ship is formed,which is used as the additional positioning capability of semi-submerged maintenance ship under greater wind and wave conditions,so as to meet the needs of emergency positioning control for sudden high sea conditions.
