Humber Gateway offshore wind farm

Utilising ROV assets and multi-skilled personnel, James Fisher Marine Services (JFMS) successfully completed seabed survey inspections and cable pull-ins on the Humber Gateway offshore wind farm.

JFMS successfully delivered seabed survey inspections and transition piece cable pull-ins on the Humber Gateway offshore wind farm.

Mobilising its in-house ROV and survey assets, JFMS set up operations from its Grimsby shoreside support base to allow it to benefit from a reduced transfer time to site.

Operating with a SAAB Seaeye Cougar-XT ROV, the experienced ROV team conducted a series of dives from a large multi-cat vessel in free swimming mode.

The work was completed on-time and within budget, which was recognised by the client and subsequently led to additional work, managing the cable pull-ins.

Working around the clock in four teams of three, JFMS utilised multi-skilled personnel to deliver a rigging solution to support the set-up of equipment on the transition pieces to conduct cable pull-in operations through the external j-tubes.

Throughput the project JFMS had to demonstrate flexibility by developing a bespoke solution for a Sampson post to assist the pull-ins.
