In August 1988, installation of the Isles of Scilly 33 kV submarine cable commenced, with contractor Balfour Kilpatrick laying the approximately 55 km, three-core copper, steel-wire-armoured cable manufactured by Pirelli General between Whitesands Bay on the Land’s End peninsula and Porthcressa Bay on St Mary’s using the converted cargo ship Star Hercules. The works formed part of the Isles of Scilly Electrification Project to link the islands to the mainland network, supervised by project engineer John Heath aboard the laying vessel and supported by associated onshore 33 kV works on St Mary’s and the Cornish mainland.
