Our state-of-the-art subsea sea survey solutions, along with our long-standing partnership with Rovco, ensure that we can offer accurate, quality data for your project – saving you time and money in the long-run and offering a truly competitive advantage.
Our experienced, expert teams have years’ of experience in delivering subsea solutions for a variety of offshore industries, continually evolving our client-centric offering and utilising the latest innovations in the sector to hone our craft. With an emphasis on accurate, real-time data, and huge investment in groundbreaking subsea technology, we can support your business with pre-emptive maintenance and fault prediction along with in-depth seabed surveying and monitoring. Our solutions are designed to maximise asset availability, productivity and boost your business’ ROI.
In today’s environments, it’s more important than ever that all proper checks and subsea cable survey operations are carried out efficiently and effectively.
Not only can a post-installation survey be a requirement set out in the licence issued by the relevant Marine Authority, but it can also be a pre-requisite to confirm the desktop study and identify anomalies along the route corridor.
Post-installation monitoring surveys are also carried out periodically to understand how the cables and subsea structure are interacting with the seabed, minimise future threats and identify preventative action that can be implemented, improving reliability and reducing un-budgeted costs. We offer these survey solutions to energy developers and owners to provide a detailed insight into seabed conditions.
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.
The CWind team works with our customers and partners to deliver a superior subsea cable survey solution, with the tools and expert knowledge to meet your requirements.
In partnership with our sister company Ocean iQ, we can provide a complete package of route engineering, subsea data and analysis, project management and a range of ROV subsea cable surveys.
Through our invested partnership with Rovco, a world-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 leaders 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 cable survey solutions utilising engineering excellence and transferrable cross-market knowledge.
Most recently, CWind and Rovco have jointly carried out a successful subsea inspection campaign at the EA1 windfarm development, where Rovco’s SubSlam 3D technology proved to offer significant added value to the customer in developing 3D models of the subsea infrastructure.
