Scope of Work
Scope of Supply
Results and Benefits
There were 20 internal cuts completed on the jacket in total:
8 off 84” OD straight x 100mm WT - average cut time 2 hours per cut
8 of 84” OD angled x 120mm WT - average cut time 2.5 hour per cut
4 off 84” OD x 120mm WT - average cut time 2.5 hours per cut
Subsea template cuts:
2 off 72” OD x 63.5mm WT locating piles - average cut time 2 hours per cut
3 off 30” OD x 25mm WT support piles - average 28 minutes per cut.
A very obvious observation when involved with any decommissioning scope of work is the age and condition of subsea structures and the importance of being prepared, yet to expect the unexpected.
James Fisher Decommissioning’s dedicated team, both onshore and offshore have valuable knowledge and experience with engineering and operational delivery of complex work scopes, ensuring we are capable to face any challenges head on.
The scope of work was completed successfully, resulting in the seamless removal of the Gyda jacket by Allseas vessel Pioneering Spirit with jacket lift technology.
“ The James Fisher Decommissioning crew were very knowledgeable with the equipment and the communication between them and the vessel was excellent.”
“The team at James Fisher Decommissioning are very keen and excellent to work with.”
