The Sea Empress oil spill, Pembrokeshire, Wales, UK


Description:

On 15th February 1996, just after 8pm, the Sea Empress was on its way to the Texaco oil refinery near Pembroke when it became grounded on mid-channel rocks at St. Ann’s Head, at the entrance of the Milford Haven Waterway in Pembrokeshire. The supertanker was loaded with more than 130,000 tonnes of crude oil. (3)

In the next week, 72,000 tonnes of Forties blend crude oil and 480 tonnes of heavy fuel oil spilled in the sea, within Pembrokeshire Coast National Park: it was one of Britain’s worst environmental disasters. Around 15,000 tonnes of emulsified oil came ashore along 200km of coastline. (4)

The wind speeds at the time of the accident prevented from starting at-sea recovery operations at the initial stage of the spill. The vessels deployed then were only able to recover 3% of the oil. Chemical dispersants were also sprayed from aircrafts and used on beaches, especially around Tenby and at Skrinkle Haven. (4)

Thousands of sea birds died or were covered in oil on the shores, despite volunteer’s attempts to save as many as possible. The area was ecologically very rich, with 35 Sites of Special Scientific Interest (SSSIs), a Marine Nature Reserve and two potential European Special Areas of Conservation. (6) On February 27, more than 1,200 oiled birds were in treatment and 400 bodies have been found. Around 5,000 birds were still flying but partly oiled. (1) No matter the efforts of the volunteers, there was a very low survival rate among oiled birds. (6) Common scoter ducks were the main victims. Their population has since made a significant recovery. 100% of the intertidal fauna died during the oil spill. Hundreds of people, including volunteers, worked to attempt to rescue seabirds and clean up the 120 miles of contaminated coastline. It costed £60 million. (3)

The area was also very important for fishing and tourism. (6) Immediately after the disaster, a voluntary ban was taken by local fishermen. Controls were organized under the 1985 Food and Environment Protection Act (FEPA): the restrictions were removed bit by bit, when the controls showed that the species were not posing risks to consumers consumption. For fishes and crustacea, this took from 3 to 8 months. Intertidal mussels and oysters were the last one, with the ban being lifter 19 months after the oil spill (4). Local fishermen then received financial compensation for the lass of income. The main touristic beaches were sufficiently clean by Easter, nine weeks after the spill, allowing their use for tourists. (4)

While the oil spill was considered one of the biggest worldwide, different sources affirmed the consequences were not as bad as they could have been. (3,4,6) According to Jon Moore, an Environmental Consultant specialized in oil spill, "it was lucky that the majority of it went outside of the Haven, where there's lots more wave action and water movement to break it up." "We really didn't find effects much beyond six or seven years after the spill, you'd struggle to find any effects now but bird population is possibly the exception." (3). Other point that it was thanks to how cold the spring of 1996 was, so feeding activity were reduced at the time of the oil spill. (4) It also happened at a period without many tourists and with a very low presence of wildlife species, that were either inactive or had already migrated. To finish, it was also due to the combination of the emergency response with chemical dispersants, the wind direction and the type of oil that made that only a relatively small volume of oil reached the coastline. (6)

The initial cause of the accident was identified as a pilot error, combined with poor weather. (6, 3) However, three years after the spilling, in January 1999, the Milford Haven Port Authority (MHPA) was fined a record £4m after pleading guilty to the offence of causing pollution under the Water Resources Act 1991. The MHPA was also required to pay a further £825,000 prosecution costs by agreement. “The judge said the Sea Empress had run aground because of the "careless" navigation of a port authority pilot, who had never before attempted to take a vessel of similar size into the harbour close to low tide. "The pilot was put in a position by the port authority where he could make an error of navigation," he said.” For Friends of the Earth, this was not enough and the pressure group was still considering whether to launch a private prosecution against the Department of Transport. (9)

This disaster also led to the introduction of a national Port Marine Safety Code, to prevent the same thing from happening again. (3). Related disasters are:  Braer – Another single-hulled oil tanker which ran aground off the Shetland Islands in 1993 spilling 56,000 tonnes of oil; the famous Torrey Canyon that ran aground between the Scilly Islands and Land's End  en route to Milford Haven; the MT Haven – (formerly known as Amoco Milford Haven)  which sank off the coast of Genoa, Italy in 1991.

After being repaired and several changes of name, the Sea Empress was finally scrapped in 2012 in Chittagong.

To answer the oil spill: (4)

- eight oil recovery vessels and twenty small support vessels were deployed, and managed to recover 3% of the oil.

- “extensive dispersant spraying operation, which included the aerial application of 446 tonnes of chemical oil dispersant in order to enhance the rate of natural dispersion of the oil. This reduced the impact of the spill by preventing an additional 57 000 to 110 000 tonnes of emulsified oil from impacting the beaches.”

- 12 tonnes of dispersant was used on the beaches.

“It has been estimated that the successful application of dispersants in this incident prevented an additional 57 000 to 110 000 t of emulsion coming ashore in South Wales.” (4)

“The total area affected by the voluntary fishing ban under the 1985 Food and Environment Protection Act (FEPA) covered about 810 square miles (2100 km 2 ) of coastal waters from St. David’s Head to Port Eynon Point, and included all the freshwater rivers and streams discharging into that area.” (4)

“The spill of 72,000 tonnes of crude oil and 370 tonnes of heavy fuel oil impacted substantially over a 100km stretch of coastline. Estimates suggest that overall 200km of coastline were affected. A further 25,000 tonnes of waste were created by the clean-up operation.” (6)

Briefly explain:The Sea Empress was one of the biggest oil spill and environmental catastrophes in the UK, together with the Torrey Canyon in 1968. There was a court case brought by ITOPF against the Milford Haven port authority because the mistake was made by the pilot they provided. According to source (10) the oil firm Texaco sued in 2002 the Milford Haven Port Authority for £10m over the Sea Empress oil disaster in 1996. The claim was submitted in February 2002, just before the final deadline. It is not the only multimillion pound action that the port authority is facing over the disaster. The International Oil Pollution Compensation Fund is seeking £34m for money it paid out to the victims of the disaster, together with any further compensation it may have to pay in future. More than 200km of the west Wales coastline was affected when the Sea Empress ran aground in February 1996, spilling 72,000 tonnes of crude oil into the estuary. The spill caused a major environmental disaster The 147,000-tonne Norwegian-owned tanker struck rocks at the mouth of the estuary near St Ann's Head - it was the third-largest tanker spill in UK waters. In a statement, Texaco said that it has made its claim to protect its legal position in the aftermath of the disaster.
It confirmed it had issued a claim form against the Milford Haven Port Authority and Milford Haven Pilotage Limited." (10).
