海上油田溢油回收船动力定位能力与艏部推进器配置优化

Optimization on the Dynamic Position Capacity and the Bow Thrusters Configuration of an Oil Recovery Vessel

对溢油回收船艏部推进器初始配置方案进行动力定位能力计算,分析其定位能力不足的原因,确定优化的技术思路;对艏部推进器的功率大小、数量、型式以及分组进行研究,得到依次递进的优化方案,提高了该船的动力定位能力,并在满足360°范围内定位能力要求的前提下降低了艏部推进器的功率配置。

Analysis of the dynamic positioning(DP)capability calculation was made to find out the reason why the initial proposal of the bow thrusters configurations had an inadequate capability and also to determine the technology road map for the further optimization.The power,number,type and the divisions for the bow thruster configuration were studied,leading to the optimized proposals.The DP capability was improved a lot and the power of the bow thrusters was lowered down while the 360 degree DP capability was still kept.
