Sleipnir Breaks Own Record with 10,100 mT Jacket Lift
> Heerema’s SSCV Sleipnir has safely and sustainably removed Shell’s 10,100 mT Brent Alpha jacket. This single jacket lift breaks Sleipnir’s recent record for lifting the 8,100 mT Jotun-B jacket. This project is Sleipnir’s fourth
decommissioning job for this summer. The vessel will continue to be busy in the North Sea before swapping the largest lifts for one of the smallest with the installation of Dana Petroleum’s P11-Unity Platform later this year.
So far, Sleipnir has safely removed
and transported more than 43,900 mT of decommissioned offshore infrastructure for recycling over this summer campaign. For the Brent Alpha jacket removal,
Sleipnir arrived at the Brent Field located 186 km northeast of Scotland’s Shetland Islands on July 23, 2020 and completed the project by offloading the jacket onto the quayside at the AF Miljøbase decommissioning site in Vats, Norway on August 11, 2020. The Brent Alpha jacket removal presented
novel challenges for Heerema, resulting in unique solutions. During the project, Heerema cut jacket legs at 7.3m diameter using a 288” Diamond Wire Cutting Tool developed alongside CUT UK, especially for the Brent Alpha removal - the largest leg diameter to have been cut this way. Also, during this project Heerema
removed and transported the conductors with the jacket, an entirely new way of decommissioning. The conductors were suspended on a Heerema Fabrication Group built Conductor Hang-off Frame made for this project.
Now that the Brent Alpha jacket has been
safely and sustainably transported to Vats, it will end its lifecycle by being over 97% recycled. Heerema’s Decommissioning Director,
Jeroen van Oosten noted that ‘there were quite some technical challenges during this record-breaking lift. Such as the cutting of the 3 x 288” legs of the platform. However, due to the excellent preparation and perseverance during execution, we successfully delivered this jacket safely and sustainably to Vats for disposal. An outstanding achievement for all involved. y
