Thialf and Sleipnir install the Leviathan Production Platform over two phases for client Noble Energy

Heerema’s scope was to transport and install the Leviathan Production Platform topsides and jacket on behalf of client Noble Energy. The project was split over two campaigns, with Thialf firstly installing the 15,200 metric ton launch jacket in February, 2019. This jacket installation was later followed by the transport and installation of the 9,200 and 15,300 metric ton topsides, executed by Sleipnir in September, 2019.

Johan Sverdrup P2 Jacket 2021

Record-breaking jacket lift for Equinor’s Johan Sverdrup P2 development.

In June, 2021, Sleipnir lifted Equinor’s 12,050 metric ton P2 jacket, which was the heaviest jacket in the world so far to be lifted directly from the transport barge. This installation method made it possible to reduce the jacket weight considerably, compared to a more traditional launch jacket, resulting in significant fabrication cost savings.
