A double-hulled tanker refers to an oil tanker which has a double hull. They reduce the likelihood of leaks occurring compared to single-hulled tankers, and their ability to prevent or reduce oil spills led to double hulls being standardized for oil tankers and other types of ships including by the International Convention for the Prevention of Pollution from Ships or MARPOL Convention. After the Exxon Valdez oil spill disaster in Alaska in 1989, the US government required all new oil tankers built for use between US ports to be equipped with a full double hull.
The Exxon Valdez oil spill was a major environmental disaster that made worldwide headlines in the spring of 1989 and occurred in Alaska's Prince William Sound on March 24, 1989. The spill occurred when Exxon Valdez, an oil supertanker owned by Exxon Shipping Company, bound for Long Beach, California, struck Prince William Sound's Bligh Reef, 6 mi (9.7 km) west of Tatitlek, Alaska at 12:04 a.m. The tanker spilled more than 10 million US gallons (240,000 bbl) of crude oil over the next few days.
Exxon Valdez was an oil tanker that gained notoriety after running aground in Prince William Sound, spilling her cargo of crude oil into the sea. On 24 March 1989, while owned by the former Exxon Shipping Company, captained by Joseph Hazelwood and First Mate James Kunkel, and bound for Long Beach, California, the vessel ran aground on the Bligh Reef, resulting in the second largest oil spill in United States history. The size of the spill is estimated to have been 40,900 to 120,000 m3. In 1989, the Exxon Valdez oil spill was listed as the 54th-largest spill in history.
Bligh Reef, sometimes known as Bligh Island Reef, is a reef off the coast of Bligh Island in Prince William Sound, Alaska. This was the location of the 1989 Exxon Valdez oil spill. After the incident, 33 US Code § 2733 mandated the operation of an automated navigation light to prevent future collisions with the reef. Despite these efforts the tug Pathfinder ran aground on Bligh Reef on Dec 24, 2009, rupturing its tanks and spilling diesel fuel. Bligh Reef is also where Alaska Steamship Company's Olympia ran aground in 1910.
Amoco Cadiz was a VLCC owned by Amoco Transport Corp and transporting crude oil for Shell Oil. Operating under the Liberian flag, she ran aground on 16 March 1978 on Portsall Rocks, 2 km (1.2 mi) from the coast of Brittany, France. Ultimately she split in three and sank, resulting in the largest oil spill of its kind in history to that date.
Joseph Jeffrey Hazelwood was an American sailor. He was the captain of Exxon Valdez during her 1989 oil spill. He was accused of being intoxicated which contributed to the disaster, but was cleared of this charge at his 1990 trial after witnesses testified that he was sober around the time of the accident. Hazelwood was convicted of a lesser charge, negligent discharge of oil, fined $50,000, and sentenced to 1,000 hours of community service.
MV Argo Merchant was a Liberian-flagged oil tanker built by Howaldtswerke in Hamburg, Germany, in 1953, most noted for running aground and subsequently sinking southeast of Nantucket Island, Massachusetts, causing one of the largest marine oil spills in history. Throughout the vessel's troubled past, she was involved in more than a dozen major shipping incidents including two other groundings; once in Indonesia while named Permina Samudra III, and again in Sicily while named Vari; and a collision in Japan.
MVNew Carissa was a freighter that ran aground and broke apart on a beach near Coos Bay, Oregon, United States, during a storm in February 1999. An attempt to tow the bow section of the ship out to sea failed when the tow line broke, and the bow was grounded again. Eventually, the bow was successfully towed out to sea and sunk. The stern section remained on the beach for over nine years until it was dismantled and removed in 2008.
Ship grounding or ship stranding is the impact of a ship on seabed or waterway side. It may be intentional, as in beaching to land crew or cargo, and careening, for maintenance or repair, or unintentional, as in a marine accident. In accidental cases, it is commonly referred to as "running aground".
Shenzhen Energy Group Company Limited, formerly Shenzhen Energy Investment Company Limited, is one of the main power generation companies in Shenzhen, Guangdong, China. It involves in developing all types of energies, researching and investing high new energy-related technologies. Huaneng Power International is now the second largest shareholder of Shenzhen Energy.
The 2009 USS Port Royal grounding was a ship grounding by the United States Navy guided missile cruiser Port Royal off Oahu, Hawaii on 5 February 2009. The ship ran aground on a coral reef, damaging both the ship and the reef. The incident received wide press coverage in Hawaii, in part because of the damage caused to a sensitive coral environment, and also because the stranded ship was within sight of Honolulu off the airport.
The 2010 Great Barrier Reef oil spill occurred on 3 April 2010, when the Chinese bulk coal carrier, MV Shen Neng 1 ran aground east of Rockhampton in Central Queensland, Australia. The vessel is owned by Shenzhen Energy Transport Co. Ltd.
Jia Yong, formerly MV Shen Neng 1 was a Chinese bulk carrier built in 1993 as Bestore. She was sold in 2007 and renamed Shen Neng 1. In 2010, she ran aground off Great Keppel Island in Queensland, Australia, spilling oil into Great Barrier Reef waters. She was repaired and returned to service, where she operated until being scrapped in 2017.
The Rena oil spill occurred off the coast of Tauranga, New Zealand in October 2011. The spill was caused by the grounding of MV Rena on the Astrolabe Reef. The Rena was a container ship and cargo vessel owned by the Greek shipping company Costamare Inc., through one of its subsidiary companies Daina Shipping. The spill has been described as New Zealand's worst maritime environmental disaster.
The Torrey Canyon oil spill was one of the world's most serious oil spills. The supertanker SS Torrey Canyon ran aground on rocks off the south-west coast of the United Kingdom in 1967, spilling an estimated 25–36 million gallons of crude oil. Attempts to mitigate the damage included the bombing of the wreck by aircraft from the Royal Navy and Royal Air Force. Hundreds of miles of coastline in Britain, France, Guernsey, and Spain were affected by the oil and other substances used to mitigate damage. It was the world's worst oil spill and led to significant changes in maritime law and oil spill responses.
The SS Wafra oil spill occurred on 27 February 1971, when SS Wafra, an oil tanker, ran aground while under tow near Cape Agulhas, South Africa. Approximately 200,000 barrels of crude oil were leaked into the ocean. The larger part of the ship was refloated, towed out to sea, and then sunk by the South African Air Force to prevent further oil contamination of the coastline.
The MV Wakashio oil spill occurred after the Japanese-controlled bulk carrier Wakashio ran aground on a coral reef on 25 July 2020 at around 16:00 UTC. The ship began to leak fuel oil in the following weeks, and broke apart in mid August. Although much of the oil on board Wakashio was pumped out before she broke in half, an estimated 1,000 tonnes of oil spilled into the ocean in what was called by some scientists the worst environmental disaster ever in Mauritius. Two weeks after the incident, the Mauritian government declared the incident a national emergency.
