Subsea cable engineering specialist Jee has completed a risk assessment of the array cables at an unnamed UK offshore wind farm.
The company said it was awarded the contract in March by the wind farm operator following concerns about the integrity of cables at the project.
Jee was tasked with compiling a framework that would be used as the basis for a risk based inspection plan.
The work included determining and ranking the risks to the array cables and providing guidance on the acceptability of each risk.
A particular area of concern was possible scour on the cable spans along the seabed and spans at the monopile bases for which Jee provided guidance on the maximum allowable free span length for each cable type using OrcaFlex analysis.
Other risks considered were cable exposure, vortex-induced vibrations and fishing interaction.
Jee said it made recommendations for mitigation and management of the risks and provided the operator with suggestions for further study.
Jee business development manager Jim Buston said: “We are very happy to have completed another cable project for this client.
“Our extensive experience of the challenges associated with subsea cables helped our client understand the most likely risks to their cables and avoided unnecessary remediation and additional survey expenditure.”
