Since oil was first shipped across the seas there have been disasters that befell the ships that transported it, taking a thick, black liquid across a stormy patch of water would be bad enough, especially during the two World Wars when torpedoes would cause devastation to these ships, but it was the modern day that saw the worst environmental disasters as these ships were being built bigger, and the threat of losing one of these to the rocks became more frequent.
Today there are fewer tanker disasters, regulations now say that any tanker must have a double bottom in order to at least give the cargo a chance to be recovered if a ship comes to grief. But it hasn't always been that way.
1967, 18 March - The supertanker Torrey Canyon grounds on Seven Stones Reef off the Scilly Isles after the captain decides to take a short cut in a journey starting the month before in Kuwait. The ship soon breaks up but all 119,000 tons of oil was released into the sea creating Britain's worst oil spill. The government realised that the slick was heading for the southern coastline and so decisions were made to bomb the wreck and burn off as much oil as possible. The bombings were a success and the images of the flaming wreck of the Torrey Canyon made headlines around the world.
1978, 16 March - After her rudder jammed off the coast of France, the crew of the VLCC (Very Large Crude Carrier) Amoco Cadiz now found themselves needing to shut the engines down in order to quickly get repairs underway. But the strong winds and heavy seas grounded the ship on the coast of Brittany. Attempts to save the ship were beaten back and the ship was smashed on the rocks, being pulled off and thrown back on again, in just over a week the wrecked ship had released her entire cargo of 220,000 metric tonnes onto the beaches. Dig deep enough today and the black sand still bears the scar of the disaster.
1989, 24 March - The VLCC Exxon Valdez was making her way through Prince William Sound in Alaska when she grounded on rocks following her departure just moments before. 37,000 tonnes of her cargo of crude was spilled but thankfully the ship was saved, as was most of her cargo still remaining on board. This was the worst oil spill in US history until 2010 when it was overtaken by the explosion that destroyed the Deepwater Horizon rig in the Gulf of Mexico.
1992, 3rd December - The double-bottomed tanker Aegean Sea ran aground off the Spanish coast of
Galicia in bad weather. Normally the disaster would be bad enough with the spilling of the cargo, but before the day was over the ship had caught fire and a huge blaze lit up the coast for several days. 67,000 tons of oil was spilled but before the fire the salvage teams did manage to save 12,000 tons by pumping it out in time. The ship later broke up and her anchors are now a nearby monument.
1993, 5th January - The Liberian registered Braer loses power in a storm and runs aground at Garths Ness in the Shetland Islands. For the next few days the ship slowly loses oil into the raging sea as salvage teams try to get the ship off the rocks. But in less than a week the ship breaks her back and spills the entire cargo of crude oil into the sea, devastating the coastline and causing the deaths of thousands of birds. Incredibly the stormy weather actually helps disperse the oil, but that which came ashore was bad enough.
1996, 15th February - While heading to the Texaco berth in Milford Haven, the Sea Empress grounded after developing a steering issue. Although tugs managed to pull her off the rocks and steady the ship, thousands of tons of the 128,000 ton cargo of crude were already spilling into the sea. The next few days saw even more disaster as the ship was grounded again as bad weather prevented the ship from being moved, eventually the Sea Empress was towed into Milford Haven and the ship repaired. The pilot in charge of the ship was demoted after a two day inquiry found him guilty of incompetence. 73,000 tons of oil was leaked into the sea, becoming the third larges spill in Britain, the 12th largest in the world.
1999, 12th December - The Erika was making her way through the Bay of Biscay when heavy weather caused the ship to break in two. The tanker sank and caused an oil spill over hundreds of miles of French coast.
2000, 13 November - During a storm a tank on board the tanker Prestige burst off the Spanish coast releasing heavy fuel oil into the sea off Galicia. Despite efforts to contain the spill and save the ship, she sank on 19th November the little fuel oil remaining on board had to be pumped out of the wreck using deep sea ROV's at 4000 meters down.
Thankfully today tanker disasters and major oil spills are not as common, new regulations, ship safety and clean-up operations have all been implemented to limit the damage should anything like this happen again. But accidents do happen and, as is clear with these few mentioned here, the weather plays a big part in causing these vessels to come to grief. Hopefully disasters on this scale are now a thing of the past.
