Sparrows Group Cable and Pipe Lay Solutions division provided personnel and equipment last year to support nearshore, export and array cabling work at the 1218MW Hornsea 1 offshore wind farm off the east coast of England.
The work was secured through three contracts with Boskalis Subsea Cables & Flexibles, DEME Offshore and DeepOcean, Sparrows said.
A specialist team worked with Boskalis to install and operate two 10Te and one 15Te cable tensioner to transfer three 245kV export cables from the vessel NDurance to the landfall site.
Sparrows said bespoke track pads were used to ensure cable clamping limits were maintained for the duration of the pull in activities and the company also provided sea fastenings packages for the equipment.
DEME Offshore was supported with the installation of the three export cables to the offshore reactive compensation station and three offshore substations using a 36Te four-track tensioner.
The equipment was integrated with the connector cable lay vessels’ system and used for spooling and laying activities for over 300km of cable.
A linear cable engine and operators were provided for DeepOcean on board the Edda Freya vessel for the array cable installation, Sparrows added.
Sparrows Group Cable and Pipe Lay Solutions chief technical officer Ewen Kerr said: “We have experienced an upsurge in business from the renewable sector in the last 12 months and the combination of the three contracts won for Hornsea 1, makes this our most significant cable lay project to date."
One of the contracts marks the first time we have conducted nearshore cable transfer operations and this is a testament to our highly trained engineering teams who worked to develop the most effective solution for our client.
