Description

technical field

[0001] The present invention relates to trestle equipment, more specifically, to a telescopic trestle system and its control method, especially suitable for semi-submersible support platforms, offshore support ships, wind power operation and maintenance ships, marine traffic ships, pilot ships, rescue boat. Background technique

[0002] With the rapid development of offshore wind power and oil exploration industries, personnel rotation and maintenance personnel disembark and disembark on offshore projects such as drilling platforms, FPSO, and wind power installations. Traditionally, cages, ship ramps, and helicopters are used to disembark and disembark. boat work. However, the problem of insufficient safety of the hanging cage is becoming more and more obvious. The ship ramp is subject to too many restrictions due to the influence of wind and waves, and the economy of the helicopter is too low. Contents of the invention

[0003] In view of the above defec...
