Adjustable underwater pipe clamp device

Abstract

An adjustable underwater pipe clamp device comprises a main support pipe, a main support pipe clamp, two branch support pipes, two branch support pipe clamps, a cable protecting pipe clamp and a vertical pipe clamp, and is characterized in that the two branch support pipes and the two branch support pipe clamps are mounted on the main support pipe, the branch support pipes are connected with the vertical pipe clamp and a vertical pipe, the two branch support pipes are connected with the cable protecting pipe clamp and a cable protecting pipe, and the main support pipe is connected with a guide pipe frame structure rod and the main support pipe clamp. By 'one clamp for two pipes' mounting way, only one main pipe clamp is connected with the guide pipe frame structure rod, unoccupied positions on various horizontal structure rods of a guide pipe frame can be reasonably used. The main pipe clamp and the branch pipe clamps are adjustable, requirement for size accuracy is met, and offshore mounting success rate is increased. Integral offshore mounting of the vertical pipe and the cable protecting pipe can be realized, offshore construction period is effectively shortened, and mounting cost is greatly reduced.

Description

technical field [0001] The invention belongs to an adjustable underwater combined pipe clip device. Background technique [0002] At present, if domestic offshore oil platforms add new wellheads and rely on the resources of existing platforms, new pipes and cable protection pipes will be built on the old platforms. The underwater part of the newly-built standpipe and cable protection pipe needs to be fastened to the structural members of the jacket. Considering the convenience and cost of construction, pipe clamps are generally used to connect them with bolts. For offshore oil platforms with relatively shallow water depth, the underwater pipe clips are generally fixed first, then risers or cable protection pipes are installed section by section from the top of the block, and finally the underwater pipe clips are locked. However, for jackets with a water depth of more than 100 meters, due to factors such as large waves, relatively narrow construction space on the blocks, tig...

AI Technical Summary

Problems solved by technology

However, for jackets with a water depth of more than 100 meters, due to factors such as large waves, relatively narrow construction space on the blocks, tight space for jacket structural members, and high requirements for the initial construction accuracy of the jacket, the above-mentioned conventional methods are difficult to implement
