Problems solved by technology
Due to the influence of wind and waves, the offshore platform will sway irregularly, which seriously affects the safety of the staff when boarding and docking at sea
Therefore, it is necessary to perform wave compensation on the gangway to compensate for the sway and heave of the hull, but the existing gangway with compensation function has low compensation accuracy, narrow compensation adjustment range, and poor bearing capacity

The invention discloses a marine platform ramp with compensation function and using method thereof. The platform comprises a ramp body and an active compensation device. The ramp body is installed on the active compensation device. A rotating support device is arranged between the ramp body and the active compensation device. The rotating support device comprises a support platform, a pitch hydraulic cylinder and a rotating hydraulic motor. The marine platform ramp with compensation function conducts real-time compensation to the horizontal swing, longitudinal swing, ascending and descending through the active compensation device to enable the ramp body to keep stable in a vicious sea condition and enhance the safety and reliability of personnel in the landing and approaching. The rotating support device drives a ramp body installed on the support platform to rotate in 360 degrees through the rotating hydraulic motor. The retraction of the pitch hydraulic cylinder changes the inclination angle between the ramp body relative and the vertical plane.
Description
technical field [0001] The invention relates to the field of offshore operation equipment, in particular to an offshore platform gangway with a compensation function and a use method thereof. Background technique [0002] The offshore platform is a structure that provides production and living facilities for activities such as drilling, oil production, and transportation at sea. The gangway is set on the offshore platform for people to get on and off the ship. Due to the influence of wind and waves, the offshore platform will sway irregularly, which seriously affects the safety of the staff when they are operating at sea. Therefore, it is necessary to perform wave compensation on the gangway to compensate for the sway and heave of the hull, but the existing gangway with compensation function has low compensation accuracy, narrow compensation adjustment range, and poor bearing capacity. Contents of the invention [0003] The object of the present invention is to provide a ...
