The technology hope to improve how FOWTs are installed
The Squid system, designed by Encomara and manufactured by Aurora Energy Services (AES) to improve how floating offshore wind turbines (FOWTs) are installed, has received a product design assessment (PDA) from the American Bureau of Shipping (ABS)
The PDA marks the next stage of international certification, following approval in principle (AIP) granted last November for Squid.
The company’s connection solution integrated pre-installed mooring lines and electrical connections into a single subsea unit. The patented technology enables rapid pre-installation of all subsea infrastructure, allowing FOWTs to be installed more efficiently and safely with ‘plug&play’ simplicity.
Modelling studies, supported by Scottish Enterprise and key developers, estimate that Squid could halve the installation time compared with traditional methods. A faster assembly and the benefits of increased weather windows and ‘tow to port’ maintenance strategies could enable Squid to save developers £1 billion per gigawatt.
ABS completed a review of the Squid system against class and industry requirements for floating offshore wind applications. The PDA follows Squid’s AIP certification, received seven months ago, and represents the next step in the qualification pathway towards Technology Readiness Level assessment and commercial adoption. A series of onshore demonstrations is scheduled for July at the AES facility in Huntly, followed by inshore wet testing and customer demonstrations at Ardersier in August.
Encomara’s managing director, Ian Donald, said, "The Squid system allows pre-installation of moorings and cables followed by rapid hook up of the FOWT , thus reducing risk and potentially doubling the number of turbines that can be installed in a typical season , which tackles a key constraint in GW-scale floating wind farm completion. We are drawing on our collective North Sea marine and engineering experience and applying it directly to one of the most pressing challenges in energy transition. To reach this milestone is a testament to the team at Encomara and Aurora Energy Services.
"Moving into live testing is the next significant step. We developed this technology in Scotland, and we are building and qualifying it in Scotland. The ambition is for it to be operating in floating wind projects across the world."
Rob Langford, ABS vice president for Global Offshore Renewables, said, "Some of the most practical solutions for floating wind will come from what has been proven to work in the traditional offshore sectors and adapting it to the unique risk profile of offshore wind. ABS is proud to support Encomara in bringing that approach to this sector, and this assessment reflects the technical depth behind it."
Squid is supported by Scottish Enterprise and the Offshore Wind Growth Partnership, and patents are secured across Europe, Asia and Australia. AES’ Huntly facility has been identified as a potential site for high-volume manufacturing as the technology scales towards commercial deployment.
