Canyon Offshore has been awarded a contract by Siem Offshore Contractors for the provision of trenching services on DONG Energy’s Hornsea Project One offshore wind farm.

Canyon Offshore’s scope will require the trenching of approximately 140km of inner-array grid cables on the wind farm, laid onto the seabed by Siem Offshore Contractors.

In order to provide the optimum trenching solution to bury the inner-array grid cables, Canyon Offshore will use both jetting and cutting methodology with its jet trencher, T1200 and its hard ground trencher, i-Trencher.

Both systems, together with two work class remotely operated vehicles, will be deployed from a single support vessel, the chartered Grand Canyon I, with operations starting in Q4 2018.

Management of the operations will be provided from Canyon Offshore’s Aberdeen base.

Canyon Offshore’s director for Commercial & Sales, Euan Roberts, said, “We have built up an enviable track
record in providing successful trenching solutions to the offshore wind-farm market in recent years in the North Sea, successfully burying hundreds of kilometres of inner-array grid cables. This has complemented our traditional oil and gas trenching market and extended our brand into the renewables industry.”

Siem Offshore Contractor’s project manager for the Hornsea One wind farm, Johann Stulemeyer, said: “In Canyon Offshore we will not only have a UK partner to complement our growing local presence, but also a technical leader in their field whose trenching solution will neatly complement our Siem Duo cable lay solution. We look forward to working together.”
