WTG Servicing and Maintenance

Bringing in too many sub-contractors during the inspection season on Wind Farms is a costly and time consuming exercise.

Our partner KES Renewables provide a full range of O&M solutions to compliment the range of external NDT techniques provided using Robotics and UAV.

Specialising in Senvion, Vestas and Nordex other OEM’s can also be covered on request throughout the UK, Ireland and Europe.

KES and Drone Inspect have their own set of WTSR and RAMS’s, however we can work under the OEM or Operator WTSR, ROP’s and AWP’s.

As most WTGs are designed to last up to and over 25 years, here we believe with the highest standard of preventative maintenance we can maximise the life cycle of the wind turbine, having already completed all major and minor services from 500 hour to end of life.

Choosing us gives you the chance to have highly skilled and authorised service and maintenance technicians(AT) which not only follow specific service and maintenance protocols, we specialise in the attention to detail. Liaising with the client management and team lead roles we can offer our services to pre-diagnose bespoke components which cost you downtime within the farm, always maximising efficiency.
