Underwater equipment mounting and recycling system and method

Abstract

The invention discloses an underwater equipment mounting and recycling system and method. The underwater equipment mounting and recycling system comprises a ship main body, wherein a crane is arranged on the ship main body. The system further comprises a mounting and recycling device, a connecting and converting device and two unmanned remote control submersibles, wherein the mounting and recycling device is used for mounting and recycling underwater equipment; the connecting and converting device is used for connecting the crane with the mounting and recycling device; and the two unmanned remote control submersibles are used for underwater construction monitoring. Te ship main body is also provided with a control device and a positioning device, wherein the control device is used for controlling the crane and the unmanned remote control submersibles; and the positioning device is used for positioning the position of a ship. As the underwater equipment is mounted and recycled through adoptions of the multi-functional ship main body and the unmanned remote control submersibles, the underwater operation cost is greatly saved; and moreover, as the two unmanned remote control submersibles have the advantages of high mounting accuracy and short operation period, the underwater operation flexibility is enhanced.

Description

technical field [0001] The invention relates to the technical field of offshore oil engineering, in particular to an underwater equipment installation recovery system and a method thereof. Background technique [0002] Offshore oil engineering operations are risky and technically difficult, and domestic offshore oil engineering, especially in deep water, is still in its infancy. At present, drilling ships and semi-submersible drilling platforms are mainly used to install and recover Christmas trees and guide substrates through drill string connections. [0003] However, the supply of drilling ships and semi-submersible drilling platforms is in short supply, and the cost of use is high. Using drilling ships or drilling platforms, using the drill string connection method to install underwater Christmas trees / guiding substrates, the operation period is long, the operation efficiency is low, and the installation cost higher. Difficult to meet the growing customer demand. [0...
