Confident post-warranty future for one of the UK’s largest wind farms


ROMAX & STATKRAFT A CASE STUDY


THE CHALLENGE


Sheringham Shoal Offshore Wind Farm is one of the UK’s largest wind farms, with a total installed capacity of 315 MW produced by 88 Siemens 3.6 MW turbines. It is situated 10-15 nautical miles off the North Norfolk Coast and is operated by Europe’s largest generator of renewable energy, Statkraft.


Having initially opted for a two-year warranty with the manufacturer, Statkraft have decided to continue their service agreement for another five years as they learn to operate independently with support from Siemens. As part of a company-wide strategy to develop operations and maintenance expertise in-house, Statkraft identified Romax as a key partner in their journey to gain more ownership over their own O&M practices and increase visibility of their wind turbine health.


FULL INDEPENDENT REVIEW


When Sheringham Shoal was due to come out of warranty, Statkraft set out to obtain a full independent review of their asset’s health. Jason Halsey, Plant Manager at Sheringham Shoal, explains: “We had some key objectives going into this inspection campaign: we wanted to maintain a high level of turbine availability and continue our industry-leading health and safety practices. We wanted to conduct 100 per cent population inspections on our drivetrains, a sample of walk downs and a 10 per cent sample on blades utilising both rope access and telescopic lens techniques.”


WHY ROMAX?


It was imperative for Statkraft that the review was carried out by a specialist independent services provider who would give an honest, unbiased and trustworthy opinion on the state of their wind farm after two years of service and almost 12 months of commissioning. Halsey said: “We ultimately selected Romax as our end of warranty partner because of their knowledge, flexibility and experience, as well as their strong reputation in the wind turbine industry. They really came into their own during the claims process after the inspection campaign had successfully been completed. Their gearbox knowledge and expertise added value and credibility to the claims that we were submitting.”
