CWind has an established track record of successfully delivering subsea and topside balance of plant (BoP) solutions that actively increase efficiencies, improve turbine utilisation and help to minimise generation downtime.

With access to world-leading Group assets, engineering teams, experienced project managers, and highly skilled technicians, CWind effectively reduces safety risk and simultaneously reduces the number of turbine visits, increasing efficiency and turbine optimisation.

Project managers can be permanently situated on site, providing greater strategic support, resulting in improved communication with the windfarm owner to provide a more efficient and effective service.

Typically, as assets age, offshore maintenance costs increase. With a significant number of offshore wind assets entering the later stages of the project lifecycle, it is evident that balance of plant degradation is a growing industry challenge.

Optimising efficiencies and maintaining the structural elements which support the wind turbine generator is crucial to ensure asset life is maximised. Without regularly scheduled maintenance and inspections offshore wind assets can deteriorate, causing faults requiring reactive maintenance leading to unplanned downtime and loss of revenue.

CWind provides statutory subsea inspections and repair, as well as pro-active maintenance, to ensure optimal asset integrity and overall longevity of an offshore wind project.

Working with clients, CWind delivers flexible, turnkey solutions, designed around specific wind farm sites, utilising an experienced fleet of in-house multi-purpose CTVs, highly skilled technicians, and project managers with a robust track record of successful project delivery.

CWind has experience at over 50 offshore wind farms across the UK and Europe, providing service support for 13GW of power since 2010, with an extensive track record of O&M delivery, including a long-term maintenance contract at Westermost Rough OFTO.

Statutory Inspections

Vigilant attention to detail for topside and subsea offshore maintenance

It is critical, that inspections are performed by experienced, methodical experts alert to every detail.

The implications if a wind turbine is offline for unscheduled maintenance can be approximately £10,000 in lost revenue a day, and when factoring in the additional costs of support vessels, technicians and equipment for repairs it could run into the millions.

For large-scale wind turbine assets and auxiliary equipment, unaddressed minor problems or oversights can quickly escalate into costly stoppages, lost revenue and expensive repairs.

CWind is on hand for both scheduled and unscheduled maintenance with fully trained technicians for turbine, cable and foundation maintenance, utilising a dedicated fuel-efficient fleet of purpose-built CTVs; all the elements required to complement OEM contracts in one bespoke package.

CWind takes the headache out of preparing, planning and executing inspections with comprehensive packages tailored to each customer and project requirement.

Our independent, certified inspectors use state-of-the-art equipment and years of experience to fully document and report defects, helping to create optimised maintenance plans.

Our turbine technicians undertake 100 and 500 hour servicing, gearbox inspections, generator alignment, “wet” service, pitch cylinder inspection & change out. Our specialist technicians also perform endoscope inspections and evaluations on gearboxes and main bearings’, minimising turbine down time.

CWind’s partnerships with key qualified specialists facilitates our statutory inspection works. These works range from simple inspection and certification of lifting equipment and self-retracting lanyards, to inspection and certification of life saving equipment.

CWind has extensive experience, a can-do approach and a proven track record in inspections of steel structures. CWind is currently providing statutory inspection teams for all of the offshore wind farm sites for a major European developer, and a 20-year contract for above water structural inspections and maintenance services at Westermost Rough offshore sub-station for Transmission Investment. Previously, CWind held a two-year contract for all above water structural and statutory inspections and maintenance services for E.ON at Humber Gateway Offshore Wind Farm.
