Rolls-Royce to supply mooring system for world’s largest semi-sub crane vessel

Rolls-Royce has signed a £8 million ($11.5M) contract to supply the mooring system for the world’s largest semi-submersible crane vessel (SSCV), Sleipnir.

The vessel will be built in Singapore by SembCorp Marine for the Dutch company Heerema Offshore Services.

Asbjørn Skaro, Rolls-Royce, Executive Vice President – Deck Machinery, said: “Mooring a giant crane is a challenge we are happy to tackle, and it’s a great pleasure working with SembCorp Marine on this unique project. The system to be delivered by Rolls-Royce builds on decades of experience with advanced deck machinery for both vessels and floating units.”

For this vessel – the “Sleipnir” – Rolls-Royce said it would deliver a  tailor made equipment package for specific operations, comprising a 12 point mooring system including electric driven winches, fairleads, wire sheaves and also a control system.

When completed the vessel will be 220 metres in length, have a width of 102 metres and a displacement of 273,700 tonnes at maximum operational draft. It will be equipped with two cranes of 10,000 tonnes lifting capacity each, providing the heavy lifting capacity to install and remove offshore facilities and install subsea structures, foundations, moorings, and floating structures in deep water.

The Sleipnir will be self-propelled with a transit speed of 10 knots, and will operate on dual-fuel.

The vessel is scheduled to be delivered from the yard in the second half of 2018.
