Connecting link pin retaining device

摘要

A connecting link pin retaining device has main frame with a lead screw threadably engaged with the main frame. The main frame has opposing upper and lower sections, and is sized and shaped to fit around a connecting link, typically used in connecting sections of mooring lines in subsea mooring applications. The retaining device is positioned around a connecting link, subsea, by a Remotely Operated Vehicle (“ROV”), and the main frame engages the connecting link and positions the lead screw in alignment with the connecting link pin of the connecting link. The lead screw is then rotated by an operating arm of the ROV, advancing the end of the lead screw against the connecting link pin and retaining it in place.
