The invention provides a catwalk active wave compensating device which comprises a lifting base. One end of a bearing table is rotationally arranged on the lifting base, and the other end of the bearing table is suspended; one end of a stretchable supporting rod is fixed to the lifting base, and the other end of the stretchable supporting rod is fixed to the bottom face of the bearing table; an MRU sensor is perpendicularly fixed to the lifting base; a distance measuring sensor is arranged on the bottom face of the farthest suspended section of the bearing table, and the distance measuring direction is set to be the downward direction; the lifting base is further provided with a controller for controlling motions of the stretchable supporting rod and the lifting base according to parameters measured by the MRU sensor and the distance measuring sensor. The invention further provides a catwalk active wave compensating method. The catwalk active wave compensating device and method are simple in principle, clear in structure, convenient to implement and low in cost, can effectively lower trestle jolts caused by swinging of a floating body along with heaving of the sea, and improves the people passing efficiency and safety.
Description
technical field [0001] The invention relates to an active wave compensation device and method for a personnel trestle, in particular to an active wave compensation device and method for a personnel and material exchange trestle between two floating bodies on the sea. Background technique [0002] At sea, it is often necessary for personnel to communicate between two floating bodies or between a fixed object and a floating body. For example, a pilot needs to enter a service ship to pilot, a ship temporarily stops on an irregular shore for replenishment, and a ship and a large floating body perform personnel replacement. etc. For this reason, a small temporary trestle bridge needs to be erected between the two for people to pass. And because there are waves unavoidably on the sea, even big waves sometimes, cause trestle bridge undulations and bumps thus, personnel and materials move inconveniently, even cause danger to take place. If you can follow the ups and downs of the w...
