Sleipnir Sets another Record on Jotun Decomm – Gallery
In the Norwegian North Sea, Sleipnir successfully removed the 8100 mT Jotun-B jacket for client Vår Energi. The platform was installed in 1998 by Heerema’s Thialf, who returned to the Jotun Field last year to remove the topsides and conductors – demonstrating the circularity of Heerema’s involvement in the lifecycle of these now retiring platforms.
“What we put in, we take out.”
For the jacket removal, Sleipnir arrived at the Jotun Field located 200 km west of Stavanger on Friday, July 11, and completed the project by offloading the jacket onto the quayside at the AF Miljøbase decommissioning site in Vats, Norway on Thursday, July 16.
The decommissioning work was completed safely, sustainably, and one day ahead of schedule; the result of excellent collaboration between Heerema and Vår Energi. The entire removal scope in the Jotun Field was completed in only four days.
During this project, skirt piles with diameters 2.7m and 80mm wall thickness were cut subsea, the largest ever done in this way. Additionally, Heerema fabricated a 40m long spreaderbar within 2mm tolerance for a tight, but perfect fit.
