Abstract

The invention provides a multi-point mooring system anchor chain lifting unit and an operating method thereof. The multi-point mooring system anchor chain lifting unit comprises a frame; the frame anda deck are of integrated structure; the top end of the frame is fitted with a guide chain roller and a rotating end of a rocking arm through a guide chain roller shaft; an anchor chain stopper is arranged on the desk; an anchor chain is passed through the anchor chain stopper and meshed with the guide chain roller; a hydraulic cylinder is arranged on the frame through a rotary shaft; the front end of a piston rod of the hydraulic cylinder is connected with the driving end of the rocking arm through a rotary shaft; an anchor chain carrier is arranged in the middle of the rocking arm through arotary shaft. The multi-point mooring system anchor chain lifting unit and the operating method thereof have the advantages that the hydraulic system features good energy efficiency and good environmental friendliness; the multi-point mooring system anchor chain lifting unit is simple in structure, and the position of the chain carrier on the rocking arm can be adjusted according to the practice to control stress upon the hydraulic cylinder; controlling with the hydraulic system has high precision, good stability and high reliability; the anchor chain can be retracted in chain ring unit, sufficient reclaiming precision is achieved, and the anchor chain reclaiming length can be controlled precisely.

Description

technical field [0001] The invention relates to the fields of semi-submersible platforms and FPSO (Floating Production Storage and Offshore Units, floating production storage and offloading units), in particular to a multi-point mooring system anchor chain lifting device and an operating method thereof. Background technique [0002] With the rapid development of the offshore oil and gas field development industry, semi-submersible platforms and FPSO have been widely used. The exploration and development of offshore oil and gas has brought about fundamental changes in the multi-point mooring system with the development from shallow seas to deep seas. The overall requirement of the multi-point mooring winch system is a qualitative improvement. [0003] Due to the overall low level of domestic support, late start of research and development, lack of application experience, and low accuracy and stability of the positioning system of related products, resulting in not widely used...
