SS Torrey Canyon was an LR2 Suezmax class oil tanker with a cargo capacity of 120,000 short tons (110,000 t) of crude oil. She was shipwrecked off the western coast of Cornwall, England, on 18 March 1967, causing an environmental disaster. At that time she was the largest vessel ever to be wrecked.
Design and history
When laid down by the Newport News Shipbuilding and Drydock Company in the United States in 1959, she had a capacity of 60,000 short tons (54,000 t). However, the ship was later enlarged in Japan to 120,000 short tons (110,000 t) 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 but chartered to British Petroleum. She was 974.4 feet (297.0 m) long, 125.4 feet (38.2 m) beam and had 68.7 feet (20.9 m) of draught..
Accident and oil spill
On 19 February 1967, Torrey Canyon left the Kuwait National Petroleum Company refinery, at Mina, Kuwait (later Al Ahmadi) on her final voyage with a full cargo of crude oil. The ship reached the Canary Islands on 14 March. From there the planned route was to Milford Haven in Wales.
In an effort to reduce the size of the oil spill, the British government decided to set the wreck on fire, by means of air strikes from the Fleet Air Arm (FAA) and Royal Air Force (RAF). On 28 March 1967, FAA Blackburn Buccaneers from RNAS Lossiemouth dropped 1,000 pounds (450 kg) bombs on the ship. Afterwards RAF Hawker Hunter from RAF Chivenor dropped cans of jet fuel (kerosene), to fuel the blaze. However, the fire was put out by high tides,[clarification needed] and further strikes were needed to re-ignite the oil, by FAA de Havilland Sea Vixens from RNAS Yeovilton and Buccaneers from the RNAS Brawdy, as well as RAF Hunters of No 1(F) Sqn from RAF West Raynham with napalm. Bombing continued into the next day, until Torrey Canyon finally sank. A total of 161 bombs, 16 rockets, 1,500 long tons (1,700 short tons) of napalm and 44,500 litres (9,800 imp gal) of kerosene were used.
Attempts to contain the oil using foam-filled containment booms were largely unsuccessful, due to the booms' fragility in high seas.
When the oil reached Guernsey seven days after the grounding, authorities scooped up the oil into sewage tankers and siphoned it off into a disused quarry in the northeast of the island. Some time later, micro-organisms were introduced to see if they could break the oil down into carbon dioxide and water. This was a limited success, so in 2010, a bio-remediation process was initiated to speed up the process.
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.
The wreck lies at a depth of 30 metres (98 ft).
In popular culture
- Serge Gainsbourg composed and recorded the song "Torrey Canyon" about the incident.
- In a 2005 episode of Top Gear, Jeremy Clarkson called James May's Jaguar XJS "The Torrey Canyon" in reference to a catastrophic oil leak. Richard Hammond continued the joke by referring to it later as "The Exxon Valdez".
- In episode 6 of series 13 of Heartbeat, "The Holiday's Over", Vernon Scripps lost all his money after joining a syndicate to insure the ship for its journey to the UK.
