Dutch offshore services company Fugro, in partnership with AS Mosley and the University of Strathclyde, has designed a real-time mooring line fatigue tracker for offshore floating wind turbines, minimizing the need for in-person inspections.

The project has received innovation funding from the Scottish Government.

The consortium won the funding to develop the tracker, which fuses the motion and position measurements of floating hulls with a simulation model to monitor fatigue, in March 2020 through the Floating Offshore Wind Technology Acceleration Competition (FLW TAC), which was run by the Carbon Trust’s Floating Wind Joint Industry Project.

“Having already demonstrated the technology in a relevant environment, Fugro and partners are now identifying opportunities to work with floating wind developers on pre-commercial projects to trial the solution offshore,” Fugro said Monday.

As a future part of the UK’s green energy generation portfolio, floating offshore wind farms will need to operate reliably and minimize in-person inspections to reduce HSSE risk exposure and remain cost-effective, Fugro said.

Drawing on its existing satellite positioning, structural and metocean monitoring systems, Fugro worked with AS Mosley and the University of Strathclyde to combine a physics-based simulation model with fatigue analysis to develop a cost-effective and streamlined methodology. 

"Instead of the current conventional 5-year subsea inspection regime, mooring line fatigue will be tracked so that inspection activities – which require vessels and remotely operated vehicles (ROVs) – are only carried out when necessary. Another benefit is that the monitoring is continuous and can be used to detect any problems or failure scenarios, such as anchor drag or trawler snagging, as they happen for quick resolution," Fugro said.

Hannah Evans, Manager at the Carbon Trust, said: “We are really pleased to see the progress Fugro, AS Mosley and the University of Strathclyde have made in developing their mooring line fatigue tracker over the past 12 months. This project has demonstrated the value of collaboration between industry and academia in Scotland to deliver innovative solutions, and addresses challenges faced by the floating wind industry to monitor mooring lines safely and cost-effectively.”

Stuart Killbourn, Fugro’s Structural Monitoring Project Manager, said: “Working with AS Mosley and the University of Strathclyde to repurpose methods and expertise from the oil and gas industry for offshore renewable energy has been incredibly exciting. Over the coming decade, efficient and reliable remote monitoring systems will be vital for the deployment of floating wind farms, which in turn are so important for meeting net-zero carbon targets for a safe and liveable world.”
