| Summary: | It developed an innovative heave compensation system (HCS) for remotely control vehicles (ROV), which changes the traditional fixed mechanical joint between shaft of drum and winches into a movable mechanical connection through many gears driven by electrical motors or hydraulic motors. By regulating the torques of these motors, the HCS can reduce the shocking force on cable caused by waves. The HCS has the following advantages including simple structure, easy operation, and suitability for limited mounting area. Based on reasonable modeling assumptions and mathematical deductions, a reduced mathematic model for the HCS was built. Simulation results of the mathematic model demonstrate that the model can illustrate the movements of HCS accurately, and the HCS can reduce the changing severity of pull forces acting on umbilical, which can relieve shocking forces caused by waves. |
