Cyberhawk was tasked by Forewind to carry out a repeat drone inspection on the Dogger Bank offshore wind farm metrological (met) masts in April 2016. Cyberhawk was chosen due to our previous experience in successfully inspecting the met masts the previous year.
Dogger Bank is a particularly challenging offshore wind site as it is the furthest offshore wind project from UK shores at approximately 150 kilometres from the coast.
The scope of work involved working form the back of a vessel to capture detailed images of all the steel lattice members and the nuts and bolts on each flange joint. A detailed inspection report was then completed, allowing the client to quickly and easily understand the condition of their structures.
Traditionally, the inspections would have been carried out using rope access technicians, however this technique increases man hours on site and involves working at height. With the use of UAVs and a two-man team of a skilled pilot and inspection engineer, it took just one day per met mast for the inspection, which would have otherwise taken at least double the time.
