A mooring chain underwater installation platform attached to an anchor

Abstract

An underwater installation platform for mooring chains attached to an anchor, including a platform base and a pin shaft. The front side of the platform base is symmetrically arranged with side slide rails, and the symmetrically arranged side slide rails are provided with a bell mouth shape; The platform base of the platform is also provided with a door type installation block and a ring pin; the bottom of the door type installation block is provided with a hook; the door type installation block is connected with the platform base through a pin shaft; the ring pin The door-type installation stopper is threaded and connected to the platform base; the door-type installation stopper is arranged in front of the side slide rail. The invention improves the working efficiency and significantly reduces the cost. The underwater robot is not only easy to operate, but also has a reliable installation function and can be reused.

Description

technical field [0001] The invention relates to the installation of mooring chains on offshore oil platforms, in particular to an underwater installation platform for mooring chains attached to anchors. Background technique [0002] The mooring system of an offshore oil platform includes a top link, an intermediate link, a bottom link and an anchor end link, and the different links are generally connected by detachable accessories. After a period of use, bottom links and anchor end links sometimes need to be disassembled, replaced and then reattached. Due to the excessive depth of seawater, it is unrealistic to install the connectors of the mooring chain links by artificial diving. Pulling the mooring chains to the barge on the water surface and then installing them has a huge workload, long installation period and high cost, and some anchors themselves cannot be pulled out and then installed again. At this time, the deep-sea robot can be used to directly operate the ROV-H...
