Heerema’s SSCV Sleipnir has safely installed the Tolmount platform in the Southern North Sea.
The project consisted of installing the 2,350 metric ton jacket and 2,500 metric ton topside constructed by Rosetti Marino.
Sleipnir traveled to the Tolmount Field located 40 km off the coast of Hull, UK, with a water depth of around 51 meters on October 7. Installation began on October 12 when the jacket was safely lifted from the Heerema barge H-408.
After finalizing jacket and pile installation, Sleipnir lifted and installed the 2,500 metric ton topside on October 13, over five hours, to complete the Tolmount Platform project.
The Tolmount Platform will be a Normally Unattended Installation (NUI), located in the vicinity of the 42/28d-13 appraisal well and will handle wet gas production from four platform wells. The Premier Oil operated Tolmount field development is on track to deliver first gas in the second quarter of 2021 and will be an important energy supplier for the UK.
