1000t自升式风电安装船动力定位系统设计

Design of Dynamic Positioning on 1 000t Self-elevating Wind Turbine Installation Vessel

风电安装船在风场中不同机位之间进行迁移和定位的过程中受到环境载荷的作用,需要设计合理的定位方案以满足定位要求。根据动力定位原理设计了1 000 t自升式风电安装船的动力定位方案,计算风、浪、流的环境载荷及推进器推力值,并进行比较。实际工程应用表明,该定位系统的设计方案在一定的海况条件下满足动力定位的精度,航速也能实现风场中不同机位之间快速迁移功能,具有良好的机动性,可为风电安装船的初期方案制定指明方向和解决思路。

The wind turbine installation vessel suffers environmental loads during navigation and positioning between wind farms. It needs to design appropriate positioning program to meet the positioning requirements. The dynamic positioning project of 1000 t wind turbine installation vessel is designed by the principle of dynamic positioning, and the calculations of environmental loads such as wind, wave and current are compared to the thrust value. The actual application shows that the dynamic positioning system meets the positioning accuracy under certain circumstance. The speed can also meet the navigation of different positions in the wind field and has good maneuverability, which shows direction and solution in the initial design of the wind turbine installation vessel.
