Dynamic positioning thrust system for Z propeller and elevating rudder

全回转推进器和可升降舵的动力定位推力系统

Abstract

The invention relates to a dynamic positioning thrust system for an all direction propeller and a lifting rudder, which belongs to dynamic positioning technical equipment in the field of ship marine technology. The dynamic positioning thrust system comprises the all direction propeller and the lifting rudder. The all direction propeller is arranged below the stern part of a ship, and a C1 axial line thereof vertically intersects with a longitudinal symmetric axis of the ship; and the lifting rudder is arranged below the bow part of the ship, and a C2 axial line thereof vertically intersects with the longitudinal symmetric axis of the ship. In an abyssal environment, when the ship is in the executive process of performing dynamic positioning, the lifting rudder and the all direction propeller cooperate together to finish tasks of overcoming surging, swaying and yawing of the ship; and under a control instruction of a control system, the all direction propeller and the lifting rudder are controlled to implement thrust executive function of the dynamic positioning according to the established proposal. The technology of the invention can be applied to large size, medium size and small size ships or semi-submersible ocean platform, has a positive significance on improving the dynamic positioning technology, and can produce obvious economic benefit.
全回转推进器和可升降舵的动力定位推力系统属于船舶海洋技术领域的动力定位技术设备。包括全回转推进器和可升降舵。全回转推进器安置在船舶艉部的下方,其C1轴线与船舶纵向对称轴垂直相交,可升降舵安装在船舶艏部的下方,其C2轴线与船舶纵向对称轴垂直相交。在深海环境中,船舶在进行动力定位的执行过程中,可升降舵和全回转推进器协同动作完成克服船舶纵荡、横荡、艏摇的任务,在控制系统的控制指令下,控制全回转推进器和可升降舵按照既定的方案,实施动力定位的推力执行功能。该发明的技术可以应用于大中小型船舶,也可应用于半潜式海洋平台,它具有改进动力定位技术的积极意义,可以产生明显的经济效益。
