The invention belongs to the technical field of wave compensation, and provides a long-stroke low-cost wave compensation system and method in an extreme marine environment. The long-stroke low-cost wave compensation system in the extreme marine environment comprises an active heave compensation unit, a passive heave compensation unit and a pulley block. The pulley block comprises movable pulleys, connecting blocks and fixed pulleys; the movable pulley is mounted on the connecting block, and the connecting block can be driven by any one of the active heave compensation unit and the passive heave compensation unit to do linear motion; a cable is wound on the movable pulley and the fixed pulley; the passive heave compensation unit is used for providing passive compensation energy according to the change of the hoisting load; the active heave compensation unit comprises a modular motor and a controller; the controller is used for driving the modular motor to generate a linear motion control signal opposite to the heaving direction of the mother ship according to the heaving motion of the mother ship, so that stable recovery and lowering of the hoisting load are realized; the device has the advantages of being small in weight and size, saving deck space and being high in stability and compensation precision.

    本发明属于波浪补偿技术领域,提供极端海洋环境下长行程低成本波浪补偿系统及方法。其中,极端海洋环境下长行程低成本波浪补偿系统包括主动升沉补偿单元、被动升沉补偿单元和滑轮组;滑轮组包括动滑轮、连接块和定滑轮;动滑轮安装在连接块上,连接块可在主动升沉补偿单元和被动升沉补偿单元中任一者的驱动下作直线运动;动滑轮和定滑轮上绕设有缆绳;被动升沉补偿单元用于根据吊装载荷的变化来提供被动补偿的能量;主动升沉补偿单元包括模块化电机及控制器;控制器用于根据母船的升沉运动来驱动模块化电机产生与母船升沉方向相反的直线运动控制信号,实现吊装载荷的平稳回收与下放;其具有重量体积小节省甲板空间、稳定性和补偿精度高的优点。
