Linch-pin is able to offer expertise and assistance to any project. Through a strong partnership between Amplemann and Linch-pin a safe and efficient Personnel Transfer system between vessels and offshore structures was created. Linch-pin assisted and offered its structural and installation engineering expertise providing practical methods of supporting and seafastening the gangway system to vessel decks.

Chain Jack


Recently Linch-pin has completed the design and fabrication of a purpose built Subsea Chain Puller.

The Subsea Chain Puller was operated by SapuraKencana Australia to decommission the NCC East Spar Buoy for Quadrant Energy.

The system was deployed subsea beneath the East Spar Buoy where its 400 t rated capacity enabled the buoy to be pulled down sufficiently to disconnected from its gravity base. The Chain Puller was then utilised to safely raise the buoy to the surface in a controlled manner where it could be towed from the field.
