Carbon Trust Offshore Wind Accelerator announces winners of Subsea Inspection competition

30 January 2018

The Carbon Trust today announced the winners of its latest innovation competition to find novel methods to inspect offshore wind substructures. The competition, launched as part of the Carbon Trust’s Offshore Wind Accelerator programme, targeted companies with new or adaptable techniques for inspection of offshore wind foundations. Entries were sought to address four specific challenges: Weld inspection for monopile foundations; Weld inspection for jacket foundations; Grout inspection for monopile foundations and Grout inspection for jacket foundations.

The challenge winners were:

  • Weld inspection for monopile foundations - Oceaneering International Services Limited, a wholly owned subsidiary of Oceaneering International, Inc. (Oceaneering) with the development of an inspection tool adapted from previous use in oil and gas.
  • Weld inspection for jacket foundations (2 winners) - Oceaneering utilising its experience in oil and gas to provide an innovative technique for inspection of nodes, and Kraken Robotics, a German company, having developed a high resolution laser imaging sensor for inspection of subsea assets.
  • Grout inspection for jacket foundations - Next Geosolutions UKCS in collaboration with Ashtead Technology and Hydrason with a technique based on the use of innovative sonar to detect gaps, cracks and disbanding of grout.
  • Grout inspection for monopile foundations (2 winners) - Uniper Technologies has developed its ultrasonic interferometric technique jointly with the British Geological Survey and has shown its success in recent offshore trials already and Next Geosolutions UKCS with the same technology as for the jacket inspection.

With the deployment of offshore wind set to almost triple in the next 10 years, the need for innovative and low-risk solutions to inspect assets is crucial.  Current estimates show that around 35-40 percent of existing monopile fleet which accounts for the majority of the pre-2012 structures, have potentially been affected by issues relating to grouted joints. Furthermore many of the structures built post-2012 will require performance monitoring. New designs such as jackets, which are constructed using welded nodes are also becoming more common presenting new inspection challenges for the offshore wind industry.

The winners will initially receive a range of tailored support from the Carbon Trust, the OWA partners and technical contractors INNOSEA and Everoze. This will include marketing advice through to engineering and industry-specific support. Following this phase those techniques which show significant potential will then be tested at operational offshore wind farms to prove their ability in real life conditions.

Michael Stephenson, Project Manager of the Foundations Working Area in the Offshore Wind Accelerator commented:

“This competition has once again shown the impressive level of innovation and ingenuity that exists within the industry. The range of winners also highlights the transferability of many techniques from other industries into offshore wind, and the potential for other players in these markets to offer services and technologies that could improve operations from both a cost and health and safety perspective.”

We advise corporates and governments on carbon emissions reduction, improving resource efficiency, and technology innovation. We have world-leading experience in the development of low carbon energy markets, including offshore wind.

The Carbon Trust has been at the forefront of the offshore wind industry globally for the past decade, working closely with governments, developers, suppliers, and innovators to reduce the cost of offshore wind energy through informing policy, supporting business decision-making, and commercialising innovative technology.

About the Offshore Wind Accelerator

The OWA programme, originally created in 2008, has been a driving force behind a range of new innovations such as; developing and demonstrating new foundations; the development and adoption of 66kV cabling; improving wind resource measurement and modelling, and new innovative access vessels. Over the last ten years the OWA has delivered over 125 projects, ranging from feasibility studies to multimillion-pound, full-scale technology demonstrations. Today, many of the innovations commercialised through the OWA are being deployed by developers building Round 2 and Round 3 wind farm sites, and are delivering direct cost reductions now.
