Sustainable Marine Anchors the Future of Offshore Renewable Energy with Launch of Swift Anchors and Next Generation Rock Anchor Installation System


Blue economy solution provider Sustainable Marine unveils its next-generation remote-controlled rock anchor installation system at Wind Energy Hamburg 2022.

The new system, dubbed AROV2, is the culmination of a decade of research, development and demonstration of direct embed anchors drilled into the seabed (see notes to editors).

He will be a key asset to Sustainable Marine’s new “Swift Anchors” division, which offers a wide range of solutions to facilitate faster and more cost-effective mooring installations for the offshore renewable energy sector, including floating wind. .

Swift Anchors’ technology has been informed by Sustainable Marine’s extensive experience in deploying its own brand of floating tidal energy platforms. It has further benefited from Scotland’s world-class offshore expertise, including extensive underwater robotics, originally developed for the region’s oil and gas sector and now supporting the marine renewable energy movement.

AROV2 was assembled by Brimmond Group, Kintore, with the control system and hydraulic module supplied by global subsea engineering specialist SMD. Outreach Offshore of Falkirk supplied the integrated control cabin and umbilical winch, and Dales Engineering Services of Peterhead carried out the fabrication work.

The next-generation system is capable of installing Swift Anchors’ full range of anchoring solutions, including large helical screw anchors in sand, cobble and clay; rock anchors in a range of rocks and cemented piles for mixed seabed geologies. Typically, rock anchors will provide an alternative to drag embedding and gravity anchors for floating wind in areas with rocky seabeds.

It consists of a control cabin and a constant tension umbilical winch which is integrated into a 20′ container. The remotely operated machine includes a 150kW underwater HPU allowing operation at depths of approximately 200m, with the ability to extend to 1,000m simply by using a longer electric and control umbilical if required .

Swift Anchors chief executive David Ainsworth says the operation is poised to support the planned take-off of floating wind, with more than 15GW of installed capacity expected by 2030, according to Global Wind Energy. Council.

“Swift Anchors is officially open for business after passing Factory Acceptance Testing (FAT) testing for our next-generation anchor installation system,” said Mr. Ainsworth. “The system was designed with capacity expansion in mind for longer and larger anchors to support the huge future opportunity of floating offshore wind. It can install anchors with a holding capacity of more than a thousand tons, meeting the requirements of floating wind power for the next decade. We are extremely grateful to our supply chain who have been instrumental in achieving this milestone, and we will now continue to demonstrate the system in use using Sustainable Marine Canada’s vessel, the Tidal Pioneer. , Nova Scotia, setting anchors to moor the company’s vessel. floating tidal energy platforms at the FORCE High Energy Demonstration Site. It will then be used to install anchors for ORPC’s TidGen deployment in Maine, USA.

Jason Hayman, CEO of Sustainable Marine, said, “This is another exciting step in Sustainable Marine’s journey as we continue to develop technologies that can help unlock the full potential of energy deployments. renewable in the marine environment. Swift Anchors will provide solutions, not only for the tidal energy industry, but will help enable the development of a truly sustainable blue economy, by opening up opportunities for developers to deploy systems at a wider range of sites. Our first tidal energy customers will benefit from using this technology later this year, and we look forward to helping shape the next tranche of floating wind projects deployed in Scottish waters and beyond.

Brimmond Group Engineering Director Tom Murdoch said: “It was a tremendous opportunity to help build a truly new device improving a notoriously difficult operation for the maritime industry as a whole. This has been a rewarding project on the part of the Brimmond team, and we look forward to continuing our collaboration with Sustainable Marine and the Swift Anchors team in the future.
