SS Torrey Canyon was an LR2 Suezmax Class oil tanker with a cargo capacity for 120,000 tons of crude oil.[1] She was shipwrecked off the western coast of Cornwall, England, in March 1967, causing an environmental disaster. At that time she was the largest vessel ever to be wrecked.[2]

Design and history

When laid down by the Newport News Shipbuilding and Drydock Company in the USA in 1959, she had a capacity of 60,000 tons. However, the ship was later enlarged in Japan to 120,000 tons capacity.

At the time of the shipwreck she was owned by Barracuda Tanker Corporation, a subsidiary of the Union Oil Company of California, and registered in Liberia[3] but chartered to British Petroleum. She was 974.4 feet (297.0 m) long, 125.4 feet (38.2 m) beam and 68.7 feet (20.9 m) draught.

Accident and oil spill

The ship left the Kuwait National Petroleum Company refinery at Mina al-Ahmadi on her final voyage on 19 February 1967 with full cargo of crude oil, reaching the Canary Islands by 14 March. From there the planned route was to Milford Haven in Wales.

On 18 March 1967, Torrey Canyon struck Pollard's Rock on Seven Stones reef between the Cornish mainland and the Isles of Scilly. An inquiry in Liberia, where the ship was registered, found Shipmaster Pastrengo Rugiati was to blame, because he took a shortcut to save time to get to Milford Haven. Additionally a design fault meant that the helmsman was unaware that the steering selector switch had been accidentally left on autopilot and hence was unable to carry out a timely turn to go through the shipping channel.[4]

On 28 March 1967 the Fleet Air Arm sent Blackburn Buccaneer strike aircraft from RNAS Lossiemouth to drop forty-two 1,000 lb bombs on the ship. Then, the Royal Air Force sent Hawker Hunter jets from RAF Chivenor to drop cans of aviation fuel to make the oil blaze.[5] However, exceptionally high tides put the fire out and it took further effort by Fleet Air Arm de Havilland Sea Vixens from RNAS Yeovilton and Buccaneers from the Naval Air Station at Brawdy, as well as more RAF Hunters with napalm, to ignite the oil. Attempts to use foam booms to contain the oil were of limited success due to their fragility in high seas. Bombing continued into the next day before Torrey Canyon finally sank.[6] A total of 161 bombs, 16 rockets, 1500 tons of napalm and 44,500 litres of kerosene were used.[7]

The wreck now lies at a depth of 30 metres (98 ft).
