Sleipnir sets two records with Sverdrup Phase 2 lifts

Heerema’s crane vessel Sleipnir has installed the 12,050-metric ton processing platform (P2) jacket for Equinor’s Johan Sverdrup Phase 2 project in the Norwegian North Sea.

According to the company, this set a record for the heaviest lift jacket installation.

The P2 jacket is the heaviest in the world to be lifted directly from the transport barge and installed. This method made it possible to reduce the jacket weight, compared to a more traditional launch jacket, resulting in fabrication cost savings, Heerema said.

This lift comes after the inshore integration of the three P2 topsides modules on behalf of client Aibel at the GMC yard in Gismarvik, Norway, in May. This mating process included the heaviest crane lift in Norwegian waters, with the MSF module weighing 13,600 metric tons.

The inshore mating of the P2 topsides included integrating three modules weighing 13,500 metric tons, 5,400 metric tons, and 4,300 metric tons. The modules were built in Thailand, Spain, and Norway and are Aibel’s largest project ever.

Heerema’s tug Kolga has towed the topsides to Aibel’s yard in Haugesund.

Johan Sverdrup is the biggest field development on the Norwegian continental shelf since the 1980s.

Phase 2, due to start up in 4Q 2022, will increase oil production through the field centre to 755,000 b/d.

Partners in the Johan Sverdrup field are Equinor (operator, 42.6%), Lundin Energy Norway (20%), Petoro (17.36%), Aker BP (11.5733%) and, TotalEnergies (8.44%).
