Pierce field lifetime extension
Replacement of Haewene BRIM FPSO mooring system
Scope of work
| Project | Jumbo’s scope of work for this extremely short-track project consisted of the Transport and Installation of 8-off anchor piles including installation and pre-tensioning of 8-off bottom chain segments (200t tension at seabed). Finally, 5-off Spiral Strand Wires had to be connected to 5-off bottom chain segments and abandoned on the seabed. |

Replacement of Haewene Brim FPSO mooring system
As part of an ongoing program to extend the lifetime of the Bluewater-owned FPSO Haewene Brim, it was necessary to replace the existing mooring system. Jumbo was tasked with the Transport and Installation of 8 anchor piles sourced from Germany, which were to be driven into the seabed in the Pierce field (offshore Aberdeen).
This project involved not only the installation and pretensioning of 8 bottom chain segments, each with a tension of 200 tons at the seabed, but also the connection of 5 Spiral Strand Wires to 5 bottom chain segments, which were subsequently abandoned on the seabed.
Within a tight timeframe of 3 months from the contract award and while adhering to the given installation window, Jumbo successfully completed the offshore installation in a safe and efficient manner. Additionally, Jumbo designed and utilized a pile guide frame to ensure precise installation of the anchor piles according to the tolerances specified by the client.
