Abstract

The invention discloses a non-submersible underwater pipeline remote operation welding maintenance equipment and method, comprising an H-shaped pipeline support frame, a casing positioner, a welding cabin, and a casing; the H-shaped pipeline support frame is equipped with a hydraulically driven Height adjustment mechanism, left and right adjustment mechanism, front and rear adjustment mechanism and pipe holding jaws; the casing positioner is equipped with hydraulically driven casing positioning claws; the casing has a wedge-shaped sealing ring; the welding cabin includes three welding cabin flaps and Six welding claws form a hexagonal structure after closing. The middle welding compartment is equipped with a drive chamber. The left welding chamber and welding compartment weight adjustment chamber are installed on the left welding compartment. The right welding compartment and welding compartment drainage chamber Installed on the flap of the right welding cabin, the left welding chamber and the right welding chamber are symmetrically arranged, and the driving chamber is equipped with a driving mechanism and a driving gear; relying on the sleeve to connect the old and new pipelines, it overcomes the need for underwater maintenance of large-scale pipelines For the problem of difficult alignment, the remote control operation and the connection process of GMAW surfacing welding + fillet welding have overcome the limitation of water depth. It can be widely used in the field of underwater and submarine pipeline maintenance.

Description

technical field

[0001] The invention relates to an underwater pipeline maintenance technology, in particular to a non-submersible underwater pipeline remote operation welding maintenance equipment and method. Background technique

[0002] With the increasing development of deep-sea oil and gas fields, the task of guaranteeing and quickly repairing deep-water and ultra-deep-water submarine pipelines after damage is becoming increasingly difficult.

[0003] The existing submarine pipeline repair technologies mainly include: non-submersible deep-water pipeline flange connection system - BRUTUS, submarine pipeline repair system DSRS (Driverless Sealine Repair System) based on claw flange connection, deep-water pipeline quick fix based on bolt clamp method. Emergency Repair System—DW RUPE, etc.

[0004] The disadvantages of high repair costs and long cycle times for large-diameter pipelines are becoming more and more apparent when remote-mounted mechanical connectors are used fo...
