Technical Research For Modeling Analysis And Simulation Of Anchor Handling System

Along with the deep sea petroleum development, the anchor positioning systemswhich is used to offshore oil engineering subsidiary ship service is becoming moreand more widely. So how to tug supplementary anchor work becomes particularlyimportant. In order to ensure the safety of the anchor operation, the thesis is aiming atmodeling and simulation for anchor handling for AHTs. This paper mainly studies thecontents:According to the ship motion equation, establish the model of a zero-speed DPforce RAO model with fluid memory template models. It is using the real FarSapphire ship related data for simulation, real simulation of the actual shipcharacteristics; According to related data for the winch of AHTs and Offshoreinstallation to establish winch motion model, towing pin, ballast and anti-roll tanksystem.Through the theoretical analysis, establish a cable model system to simulate wirerope movement. This simulator built the relationship among cable span, anchor depthand the anchor cable force.This thesis combines vessel model, cable model, and winch model together tomake the simulation for the real anchor handling by AHTs. The simulator cansimulate the movement of AHTs, cable system and anchor position. At the same time,it verify that the towing pin, ballast and anti-roll tank system is very important for the...
