Abstract

The invention discloses a telescopic trestle system and a control method thereof. The telescopic trestle system is mounted on a support platform or a support ship and comprises a cylinder body arranged on the support platform or the support ship, a rotary chassis is connected to the cylinder body through a rotary mechanism, a hydraulic pump station and a cab are arranged on the rotary chassis, a trestle fixing section is connected to the rotary chassis, the hydraulic pump station is connected with the trestle fixing section through a variable-amplitude mechanism, the front end of the trestle fixing section is connected with a trestle moving section through a telescopic mechanism, and a landing device and an inclined ladder are arranged on the front end of the trestle moving section. The telescopic trestle system further comprises a motion compensation control system, and the motion compensation control system comprises a filter module and a controller module. According to the telescopic trestle system and the control method thereof, the safety conveying problem of personnel under the offshore severe sea condition is solved, and conveying of electricity, water, oil and mud can be provided.

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...
