Wind Turbine Inspection: Sheringham Shoal Offshore Wind Farm

Case Studies

Statoil is an important player in the UK’s burgeoning offshore wind sector. The Sheringham Shoal field began operation in 2012 and is located 10-15 miles off the Norfolk Coast.  With 88 offshore wind turbines, covering an area of approximately 35km², Statoil wanted a wind turbine inspection service which would minimise downtime and mitigate safety risks.

The UAS wind turbine inspection service enhanced Statoil’s business operations by:

  • Improving staff safety by reducing working at heights and elimination of transfer at sea
  • Improved inspection times increase operational efficiency
  • Providing high quality HD imagery measuring and grading damage for faster repair

Increased efficiency and reduced costs

The Sheringham Shoal inspection took 20 working days and 200 UAS flight deployments.  The inspected turbine blades measured 52 metres in length, with a turbine tower height of 80 metres. It took only 8 minutes to inspect each turbine blade using the Unmanned Aerial System.

Martek Aviation delivered a comprehensive wind turbine inspection report, including high-resolution images providing sight of all four sides of each blade, to identify any minor damage and maintenance needs straight away.

Dale Symonds, Senior Engineer (Statoil – Sheringham Shoal)

“Martek Aviation is a professional company providing world class wind turbine inspection services. The UAS high-resolution camera has allowed us to perform excellent quality inspections on all turbine blades providing us with confidence and clarity. The service has allowed us to become more efficient, safe and profitable with our wind turbine inspections moving forwards.

Their on-site inspection team and back office support provided excellent customer service and their team experience demonstrates flight professionalism. I would have no hesitations in recommending Martek Aviation as the preferred means for conducting this type of inspection in the future and we are already taking about how we can continue working together across other Statoil wind parks.”
