Specifically, Sleipnir installed the two main topsides with a total weight of 24.500 tonnes in less than 20 hours.
According to the company, Sleipnir was opted for the operation 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.
Moreover, Sleipnir began operations last July and belongs to Heerema Marine Contractor’s fleet. The LNG-powered crane vessel is able to lift up to 20,000 tonnes in tandem with its two revolving cranes, and can be deployed globally for installing and removing offshore structures.
The crane vessel can accommodate 400 people.
Heerema’s CEO Koos-Jan van Brouwershaven commented
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.
Another record was achieved in July, this summer, when Titan LNG conducted the largest LNG bunkering in the world with Heerema Marine Contractors’ new semi-submersible crane vessel.
