Research on the Interference Between Propeller and Propeller in Dynamic Positioning Vessel

本文针对动力定位船舶在推力分配中桨-桨之间的水动力干扰问题,基于二次规划算法提出了一种改进的避免桨-桨干扰的策略。以一艘海洋平台供应船模型为研究对象,通过仿真验证了该算法可以有效地降低推进器的推力损失,提高船舶的定位精度,降低推进系统的能耗。

In order to solve the problem of hydrodynamic interaction between propeller and propeller in dynamic positioning ship, an improved strategy for avoiding the interaction is proposed which based on the quadratic programming algorithm. Taking a platform supply vessel model as the research object, the simulation results show that the algorithm can effectively reduce the thrust loss of propeller, improve the positioning accuracy of the vessel, and reduce the energy consumption of the propulsion system.
