Allseas is testing the jacket lift system for its vessel Pioneering Spirit.
During operations, the aft-mounted beams lift and support entire jackets weighing up to 20,000 tonnes. The technology enables direct transfer of structures to and from the quayside and eliminates the need for support barges. Allseas said this will lead to significantly shorter operating times and therefore major emissions savings.
In-harbour trials include raising and lowering the 170 m lifting beams individually and, when connected, simultaneously. This enables Allseas engineers to calibrate load measurements and verify the control modes and safety systems.
