photo The stinger handling system on the SapuraKencana 1200. The Stinger Handling System uses an A-frame, and was developed in parallel with the ship design. This integrated approach resulted in a very compact system, optimally integrated in the aft ship, with due consideration given to*** stinger section handling***, maintenance and accessibility during operations. In addition to stinger handling, the **A-frame **can also be used for Deepwater Lowering purposes, using the wire of the Abandon & Recovery (A&R) system.

Stinger gantry frame
Stinger tackle system
Stinger slack rope protection system


The stinger gantry frame is the intermediate structure between the stinger and the stinger tackle and the vessel. Furthermore, the stinger gantry frame supports the stinger hoisting winches, the service cranes and two hoisting beams which are mounted to the frame. The stinger tackle system is used to adjust the stinger angle and to transfer the load to the gantry frame.
