Sscv sleipnir full#
Sleipnir is the world’s most sustainable SSCV, and during the project the vessel performed the full removal operations while running on emission-reducing LNG fuel. The conductors were suspended on a Heerema Fabrication Group built Conductor Hang-off Frame made for this project. 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.Īlso, during this project Heerema removed and transported the conductors with the jacket, an entirely new way of decommissioning. The Brent Alpha jacket removal presented novel challenges for Heerema, resulting in unique solutions. So far, Sleipnir has safely removed and transported more than 43900 mT of decommissioned offshore infrastructure for recycling over this summer campaign.įor the Brent Alpha jacket removal, Sleipnir arrived at the Brent Field located 186 km northeast of Scotland’s Shetland Islands on Jand completed the project by offloading the jacket onto the quayside at the AF Miljøbase decommissioning site in Vats, Norway on August 11, 2020. 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. This project is Sleipnir’s fourth decommissioning job for this summer.
This single jacket lift breaks Sleipnir’s recent record for lifting the 8100 mT Jotun-B jacket. Heerema’s SSCV Sleipnir has safely and sustainably removed Shell’s 10100 mT Brent Alpha jacket.

For Heerema, safeguarding our employees and those who work alongside Heerema is always the top priority.Heerema's SSCV Sleipnir breaks own record with 10100 mT jacket lift It is essential to note that all companies involved followed the strict government guidelines to protect their workforces during the ongoing COVID-19 outbreak. Heerema’s CEO, Koos-Jan van Brouwershaven noted that ‘we set records to break them, and we are proud to have worked alongside our client Vår Energi to complete the Jotun-B removal with mighty Sleipnir safely, sustainably, and in the shortest possible time.’ Now that the Jotun-B jacket has been safely and sustainably transported to Vats, it will end its lifecycle by being recycled up to 99%.
By using LNG, Sleipnir reduces CO2 emissions by 25%, reduces NOx emissions by 92%, reduces SOx emissions by 99%, and Particulate Materials by <99% compared to traditional Marine Gas Oil crane vessels. Sleipnir is the world’s most sustainable SSCV, and during the project, the vessel performed the full removal operations while running on emission-reducing LNG fuel.
Additionally, Heerema fabricated a 40m long spreaderbar within 2mm tolerance for a tight, but perfect fit. The entire removal scope in the Jotun Field was completed in only four days.ĭuring this project, skirt piles with diameters 2.7m and 80mm wall thickness were cut subsea, the largest ever done in this way. The decommissioning work was completed safely, sustainably, and one day ahead of schedule the result of excellent collaboration between Heerema and Vår Energi.
