Exploration of a New Research Venture Focused on Reducing Failure and Slashing Maintenance Expenses of Wind Turbine Dynamic Cables and Anchoring Lines.
In a bid to revolutionize the floating offshore wind industry, a new project titled "Mooring Line and Dynamic Cable Monitoring and Replacement Methodologies" has been launched in the UK. The Offshore Renewable Energy (ORE) Catapult, a leading organisation in the sector, commissioned the project.
The project's primary objective is to minimise failures and repair costs related to mooring lines and dynamic cables on floating offshore wind farms. By improving the effectiveness of monitoring, maintenance, and replacement processes, the project aims to enhance reliability and reduce operational expenses associated with these critical components.
The project focuses on developing comprehensive insight into monitoring and maintenance methods for mooring lines and subsea dynamic cables, essential for the stability and power transmission of floating wind turbines. Real-time monitoring technologies, potentially leveraging sensor systems like embedded fiber optics and strain gauges, are being enhanced to detect load conditions, corrosion, and internal wire breaks with high accuracy.
The deep-water environments where floating turbines are deployed pose significant challenges, including corrosion resistance and durability under dynamic loads. The project addresses these challenges to extend service life and lower lifetime costs. Additionally, the project provides methodologies that support timely replacement decisions to avoid catastrophic failures and reduce downtime, thereby increasing overall floating wind farm operational efficiency.
The project aligns with the UK's broader goals to expand offshore wind capacity sustainably and cost-effectively, especially as floating wind farms venture into deeper waters requiring advanced mooring and cable solutions. The project is expected to significantly contribute to reducing maintenance costs and risks associated with dynamic cables and mooring infrastructure in the floating wind sector.
The Floating Offshore Wind Centre of Excellence, a collaboration between ORE Catapult, Apollo Engineering, and DOF Subsea UK, is delivering the project. The Centre aims to create opportunities for the UK supply chain and accelerate the build-out of floating wind farms.
Historically, mooring repair costs for oil production assets in the UK have exceeded GBP 400 million for a single incident. Cable failures have accounted for between 70% and 80% of UK offshore insurance claims. The Centre of Excellence is working towards an internationally recognized center of excellence in floating wind, aiming to identify preventative measures and innovative technologies for mooring line and dynamic cable issues.
Although detailed results and quantified findings have not been published yet, the emphasis is clearly on delivering robust monitoring, predictive maintenance, and optimized replacement strategies for these critical floating wind components. The learnings from the project could potentially reduce the overall cost of mooring line and dynamic cable repairs and replacement across the UK and internationally.
