The Western High Voltage Direct Current (HVDC) Link is a major electricity transmission project beingjointly developed by National grid Electricity Transmission and SP Transmission. The projectcomprises the installation of two HVDC submarine cables between Scotland and England for a totallength of the submarine route of approximately 385 km. The link connects England with the landfallof the Wirral Peninsula and Scotland at the Hunterston area. Prysmian has awarded ASDG with asubcontract for the submarine cable laying and protection for the Western HVDC Link project atWirral. ASDG’s SoW included cable loading of 2x36.2 km HVDC and 36.2 km FOC and simultaneouslaying and burial of bundled cable. The SoW also included assistance to cable pulling to shore up tothe sea-land joint position, pre-lay grapnel run, the performance of a visual pre-lay survey and theexecution of post-lay seabed survey.

Assodivers protected the two 380 kV alternate current cable circuits between the VillafrancaTirrena (Sicily) and Scilla (Calabria) power stations. Six (6) power cables and the two (2) opticalcables laid in bundle with two power cables where buried in practice throughout the route. Eachroute was in average 38km and crossed 6 other previously installed services, two gas pipes andfour telecom cables. The installation work was divided between the two circuits (of three cableseach) and those were laid with about one year interval between each other. The first circuit onlywas further split in two campaigns.

This project is a power link between Italy Mainland to Sardinia via a 500 KVAC circuit, consisting oftwo main cables Pole 1 and Pole 2 and respective anode and cathode cables at both ends of thelink. The execution carried out on two phases in 2008 and in 2010. The scope of work includedthe protection works of all cables from the landing points up to water depths of 680m. Despitethe deep water jetting operations, Assodivers had also performed the utilization of two supportvessels operating in parallel at a certain stage of the project in order to minimize the time that thecable was left unprotected between the laying and the final protection.
