Abstract

The invention discloses a wave compensation gangway ladder system and a control method thereof. The system comprises a control module; the rotary platform comprises a first motor connected with the control module; the pitching mechanism comprises a second motor connected with the control module; the telescopic mechanism comprises a third motor connected with the control module; the intelligent module is arranged at the tail end of the telescopic mechanism and connected with the control module, the intelligent module comprises three intelligent units, and each intelligent unit is used for obtaining the ship attitude information on the corresponding direction axis and the distance between the tail end of the telescopic mechanism and the docking target; the intelligent module is used for establishing and training a wave compensation gangway ladder prediction model, inputting ship attitude information at a previous moment T1 into the trained wave compensation gangway ladder prediction model, outputting a wave compensation gangway ladder compensation value at a later moment T2 and transmitting the wave compensation gangway ladder compensation value to the control module; the control module is used for controlling the first motor, the second motor and the third motor to move according to the compensation value of the wave compensation gangway ladder, the distance from the tail end of the telescopic mechanism to the docking target and a safety limit preset value.

Description

technical field [0001] The invention relates to the technical field of offshore transfer operation equipment, in particular to a wave compensation gangway system and a control method thereof. Background technique [0002] With the rapid growth of my country's economy and the gradual improvement of scientific and technological capabilities, offshore engineering operations have become more and more frequent, and more and more offshore transfer equipment has been put into use. The wave compensation gangway device is a bridge connecting the ship and the fixed offshore platform, and it is also the necessary marine equipment for offshore engineering operations and deep-sea resource development. Under normal circumstances, ships have to deal with various resistances when sailing at sea, including the influence of factors such as sea wind, waves and currents. These nonlinear factors cannot show a certain regularity, and advanced algorithms and wave compensation technology are often ...
