自升式海洋平台平衡升降控制策略及试验

Equilibrium Lifting Control Strategy and Test of Jack-up Offshore Platform

受海底环境和载荷变化等因素影响,自升式海洋平台在升降过程中需实时确保姿态平衡。针对四桩腿多电机驱动自升式海洋平台的上升作业,提出一种速度-倾角偏差耦合同步控制策略。搭建了四桩腿海洋升降平台物理模型,根据该控制策略完成了模型平台的电气设计及上升程序设计,并进行了模型平台上升时的平衡试验,平台姿态倾角能够保持在合理范围内,验证了该升降系统控制策略的正确性,可为海洋平台的平衡升降控制提供参考。

Affected by factors such as the seabed environment and load changes, the jack-up offshore platform needs to ensure the posture equilibrium in real time during the lifting process. According to the jacking operation on a four-leg multimotor-driven jack-up offshore platform, a synchronous control strategy of speed-inclination deviation coupling is presented. A physical model of a four-leg offshore lifting platform is built. The electrical design and the lifting program design of the model platform are completed according to the control strategy, and the equilibrium test of the model platform lifting operation is carried out. The posture inclination angle of the model platform is guaranteed to be within a reasonable range. The correctness of the control strategy of the lifting system is verified, which can provide reference for the equilibrium lifting of offshore platform.
