When personnel go ashore at sea, wave compensators can be installed in the channel to reduce the shaking of the landing channel.

The piston component is arranged in the chamber, and the ship connection device is installed on the piston component, and is built on a fixed seat arranged on the ship connection device through a temporary bridge. When the piston is pulled and moved upward, the liquid in the chamber will quickly flow in the pulling direction through the gap between the piston and the chamber to generate a pressure difference, further limiting the movement speed of the piston to allow the ship connection device to move slowly, thereby achieving the effect of allowing personnel to smoothly land on offshore buildings; Prior art 2 (publication number CN117144780A, Chinese patent published on December 1, 2023) A wave compensator with The invention discloses a multifunctional offshore platform boarding trestle, wherein the wave compensation control mechanism is fixed on the deck of the operation and maintenance ship through a base bottom plate, the bottom universal joint is fixed on the upper surface of the base bottom plate, the top universal joint is fixed on the lower surface of the base top plate, the lower part of the compensation cylinder is connected to the bottom universal joint, and the upper part of the compensation cylinder is connected to the top universal joint; the fixed end of the horizontal driving member of the trestle mechanism is connected to the fixed frame of the trestle, and the moving end of the horizontal driving member is connected to the movable frame of the trestle; the horizontal driving member drives the movable frame of the trestle to move along the guide groove through the vertical guide member; the wave compensation control mechanism also includes a micro-inertial navigation sensor, and the compensation cylinder performs wave compensation on the trestle mechanism according to the motion information of the operation and maintenance ship transmitted by the micro-inertial navigation sensor.
