A Fugro-led consortium that includes AS Mosley and the University of Strathclyde has designed a mooring line fatigue tracker that safely and cost-effectively monitors offshore floating wind turbines, thanks to innovation funding from the Scottish Government.Fugro announced it on June 14.

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.

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