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 reduce turbine downtime.
With access to Group assets, engineering teams, adept project managers, and highly skilled, local technicians, CWind effectively reduces safety risk and simultaneously reduces the number of turbine visits, increasing efficiency and turbine optimisation.
Project coordinators can be permanently situated on site as a client focal point, providing greater strategic support and resulting in improved dialogue with the planner and capable interface management.
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, offshore wind assets can deteriorate, causing faults requiring reactive maintenance leading to downtime and loss of revenue.
CWind provides statutory inspections, pro-active maintenance, and pre-emptive repairs 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 2009, with an extensive track record of O&M delivery, including a long-term maintenance contract at Westermost Rough. Supported by Global Marine Group shared services, equipment and assets, CWind is well versed to deliver large scopes of maintenance projects, including marine logistics, foundation inspection and preventative maintenance.
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 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.
Not only can a post-installation survey be a requirement set out in the licence issued by the relevant Marine Authority, but also a pre-requisite where cable installation design cannot fully mitigate the risk of cable exposure.
Post-installation monitoring surveys can also be carried out periodically to minimise future threats and identify preventative action that can be implemented, improving reliability and reducing un-budgeted costs.
From a fleet of 17 CTVs strategically positioned around the UK and Europe, we offer these survey solutions to energy developers and owners to provide a detailed insight into seabed conditions. Completing the surveys from vessels already located at the wind farms, make it a cost effective solution that maximises the benefits of time on site.
Customers gain from using vessels and crews with experience of their sites, with many operational approvals already in place. Our survey solution also eliminates transit times to site and minimises risk of weather delays.
Scour condition monitoring and volume calculations are performed using high resolution multi-beam bathymetry MBES and side-scan sonar SSS surveys around WTG foundations. This is often where tidal currents have removed material which might compromise the security of foundations or exposed cables. 2D/3D images, maps and volumetric calculations of material moved are produced, at acquisition speeds of 3-4 knots.
The use of multi-beam and side-scan sonar surveys to detect cable exposure and measure depth of sediment cover over cable by comparison of seabed with previous surveys. Use of high resolution MBES digital terrain models, with highly accurate vertical correction for tides to monitor cable depth of cover without the use of ROVs. Acquisition speeds of 3-4 knots.
Cable crossing condition, CPS protection monitoring and depth of burial verification surveys using ROV based tools such as TSS 440/350, Innovatum Smartrak or the Pangeo 3D Seismic system.
BENTHIC SURVEY MONITORING
Analysis of infauna (subsurface) sampled by grabs or cores and the epifauna (above surface) sampled by trawls or dredges, accompanied by the sub-sampling of sediments for analysis of particle size distributions and contaminant concentrations.
Through our invested partnership with Rovco, the world’s leading provider of ROV and hydrographic surveys using 3D and AI, CWind provide advancements to the offshore renewables industry through the continuous improvement of available and future-proofed digital technology.
Our invested partnership minimises risk to offshore personnel, through smarter ways of working, reducing the amount of time spent offshore.
Additionally, we provide optimised state of the art live 3D vision technology to acquire accurate, high quality data, delivered from a fleet of multi-purpose vessels and ROVs using highly experienced personnel.
Together, CWind and Rovco empower clients with an improved understanding of offshore wind assets, supporting industry behaviour change, to make timely, informed decisions throughout the project lifecycle.
Utilising trend analysis, we can identify likely faults on subsea structures, as well as within the internal environment of the monopile.
Applying our intelligence to support pre-emptive asset maintenance and fault prediction, ensures effective asset management and maximised integrity, providing clients with peace of mind.
We offer a proactive approach to digital data management, utilising already deployed vessels to optimise existing offshore operations, maximise resource and add value to projects.
We have strategically located vessels, and technical knowledge, to deliver global subsea solutions, responding rapidly to meet client needs.
As part of the Global Marine Group, CWind has a legacy of successful project delivery across multiple markets; continually evolving subsea solutions utilising engineering excellence and transferrable cross-market knowledge.
