Sparrows Group Cable and Pipe Lay Solutions (CPLS) has delivered its largest renewables project through three contracts related to the 1.2GW Hornsea Project One offshore wind farm. The three contracts were awarded through VBMS; DEME Offshore, formerly known as Tideway; and DeepOcean. The work scope saw Sparrows provide equipment and personnel to handle the nearshore, export and inter-array cables for the Hornsea One offshore wind farm.Working closely with VBMS, a specialist team of personnel installed and operated two 10Te cable tensioners and one 15Te tensioner to transfer three 245kV export cable from the vessel NDurance to the landfall location. Bespoke track pads were used to ensure cable clamping limits were maintained for the duration of the pull in activities and Sparrows provided sea fastenings packages for the equipment.
The company also supported DEME Offshore with the installation of the three export cables offshore to the Reactive Compensation Station (RCS) and onto the three substations using a 36Te 4-Track Tensioner.
The equipment was integrated into the Connector cable lay vessels’ lay spread system and used for spooling and laying activities for over 300km of cable. Data from the tensioners was logged and fed to the clients monitoring software by serial output throughout the project.
A further contract was awarded to Sparrows by DeepOcean to provide a Linear Cable Engine and operators on board the Edda Freya for the inter-array cable installations.
