Sheringham Shoal O&M Project

Seajacks have completed another successful Operations & Maintenance (O&M) project in the offshore wind industry.

Seajacks were commissioned by Statkraft, operator and joint owner, to support 2 gearbox changes on Sheringham Shoal Offshore Wind Farm. Located off the Norfolk coast, Sheringham Shoal consists of 88 3.6MW turbines, providing enough power to supply energy to 220,000 homes and is jointly owned by Statkraft, Statoil and Green Investment Bank.

Seajacks provided specialist technicians, tooling and lifting equipment for the project, working closely with the Statkraft project team in all stages of planning from the tooling, turbine preparation gearbox exchange and re-commissioning of the 2 turbines. Vessel delivery was coordinated in conjunction with the delivery of 2 gearboxes from the Original Equipment Manufacturer (OEM).

Collaboration throughout the project between Seajacks and Statkraft ensured the delivery and installation of replacement components went smoothly and was delivered in a timely manner.

This is the first time that a major component has been exchanged on a Siemens model turbine offshore without Siemens managing the project and providing the heavy lift team within the UK. The technical resource “heavy lift team” provision during the operation was carefully put together by both project teams from Statkraft and Seajacks utilising supporting manpower from 3Sun.

The resounding success of the project has helped in paving the way for Seajacks to deliver independent major component replacement for out of warranty windfarms. This supports the windfarm owners and operators in providing a more cost effective approach to turbine component replacements without the OEM.
