A docking transportation system and method for an offshore platform and a supply ship

Abstract

The invention discloses a docking transportation system between an ocean platform and a supply ship. When the supply ship sails to the ocean platform, the docking transportation channel installed on the ocean platform is rotated and lowered, and at the same time, the safety protection nets on both sides and in front of the channel are installed on both sides of the channel. The telescopic arm of the crane is unfolded, and the cage realizes the transportation of personnel and materials through the docking transportation channel. The invention can monitor the sea conditions in real time, adjust the position of the locking device and dock with it according to the actual height of the supply ship, realize the relative stillness of the supply ship and the ocean platform, and the normal fluctuation of the sea surface can be relieved by the sliding device, realizing sliding docking and automation high degree.

Description

technical field [0001] The invention relates to marine equipment technology, in particular to a docking transport system and a docking transport method for a supply ship and an ocean platform, which transport personnel and supplies for the ocean platform. Background technique [0002] With the development of offshore oil and gas and the development of offshore oil and gas, a large number of offshore platforms have emerged. Due to the long working cycle and heavy workload of offshore platforms, regular replenishment of materials and personnel replacement are required, and the supply and transportation system is particularly important. [0003] Offshore platforms are an indispensable part of marine equipment. According to their structural characteristics and working conditions, they can be divided into three categories: fixed, semi-fixed and movable. They are mainly responsible for oil production, drilling and observation. There will be helicopter platforms on some larger ocea...

AI Technical Summary

Problems solved by technology

[0004] Under normal sea conditions, the offshore platform is usually replenished by supply ships, and the platform is transported to the platform by the crane on the offshore platform between the platform and the supply ship. However, there are many disadvantages in this method: first, when the supply ship approaches How to ensure that the supply ship remains as stationary as possible relative to the platform; secondly, there are great safety risks in transporting personnel and supplies through cranes; finally, cranes are generally installed on the top of offshore platforms, which means that personnel and supplies are normally only It can be transferred to the top of the platform, but a second transfer is required, which is time-consuming and laborious
