This sets a world record: lifting a module of 15,300 tonnes was never done by a crane vessel before.
For the Leviathan development Sleipnir installed its two main topsides with a total weight of 24.500 tonnes in less than 20 hours. Sleipnir was selected for the job in order to save budget; as Sleipnir is capable of lifting large and commissioned modules, the installation process takes less offshore time and is therefore less costly.
Semi-Submersible Crane Vessel (SSCV) Sleipnir entered into service last July and is part of Heerema Marine Contractor’s fleet. It is LNG-powered. Two revolving cranes can lift up to 20,000 tonnes in tandem. Sleipnir can be deployed globally for installing and removing offshore structures.
Heerema’s CEO Koos-Jan van Brouwershaven about the record lift: ‘We are very proud of this achievement. Sleipnir is a unique vessel. It is LNG-powered and thus climate friendly. And our client enjoys the benefits. Because lifting larger modules means less time involved and therefore a smaller budget will suffice for a job.’
Noble Energy’s VP of Major Projects George Hatfield: 'The long and successful relationship between Noble Energy and Heerema continues with the safe and efficient execution by Sleipnir and her team. As always, Heerema’s commitment to provide operational excellence can be seen throughout this project'.
