The MV Wakashio oil spill occurred offshore of Pointe d'Esny, south of Mauritius, after the bulk carrier Wakashio ran aground on a coral reef on 25 July 2020 at around 16:00 UTC.[1] The bulk carrier began to leak fuel oil in the following weeks. As of 10 August, an estimated 1,000 metric tons of oil had spilled from the ship.

Background[edit]
MV Wakashio, a large capesize bulk carrier, was built by the Universal Shipbuilding Corporation of Tsu, Japan.[2] She was laid down on 23 September 2004, launched on 9 March 2007, and was delivered on 30 May 2007.[2] She has a deadweight tonnage of 203,000 tons, a length overall of 299.95 metres (984 ft 1 in), and a beam of 50 metres (164 ft 1 in).[2][3] She is powered by a single diesel engine that gives her a service speed of 14.5 knots (26.9 km/h).[2] The ship belongs to Okiyo Maritime Corp., an associate company of Nagashiki Shipping Co. Ltd.,[4] and is operated by Mitsui O.S.K. Lines.[5] At the time of her grounding, Wakashio was flying under a Panamanian flag of convenience, despite her Japanese ownership.[3] The ship was sailing without cargo,[6] and departed from Lianyungang, China on 4 July, stopped in Singapore, and was scheduled to reach Tubarão, Brazil on 13 August.[7] A crew of 20 was on board,[5] none of whom were injured.[4]
Japan's ClassNK inspection body said in a statement on August 11 that the ship had passed an annual inspection in March. The company said they doubted the incident would have a significant effect on their earnings.[8]
Accident[edit]
Wakashio ran aground on a coral reef on 25 July, but did not immediately begin leaking oil.[6] Oil began to leak from the ship on 6 August,[6] by which time Mauritius authorities were trying to control the spill and minimize its effects, isolating environmentally sensitive areas of the coast, while waiting for help from foreign countries to pump out an estimated 3,890 tons of oil remaining on board.[9] By 10 August, about 1,000 metric tons of fuel had spilled, with estimates of the remaining oil onboard ranging from 2,500 to 3,000 metric tons.[6][10] High winds and 5 metres (16 ft) waves halted cleanup efforts on 10 August; visible cracks in the hull of the ship led to worries that the ship might "break in two," according to Mauritius' prime minister Pravind Kumar Jugnauth.[11] Jugnauth said that 3,000 tons of oil had been pumped out of the ship's fuel reservoirs. Data from Finnish Iceye satellites indicated the spill had increased from 3.3 km2 (1.3 sq mi) on 6 August to 27 km2 (10 sq mi) on 11 August.[12]
The island's environment minister Kavy Ramano, together with the fisheries minister, told the press that it was the first time that the country faced a catastrophe of this magnitude, and that they were insufficiently equipped to handle the problem.[3]
The grounding happened at an area which is listed under the Ramsar convention on wetlands of international importance and near the marine park of Blue Bay.[3][13] Tourism plays a major role in the economy of Mauritius, accounting for about 63 billion Mauritian rupees (US$1.59 billion) in spending in 2019, and is centered around marine scenery and animals likely to be endangered by the oil spill.[14] Greenpeace stated that "[t]housands of species [...] are at risk of drowning in a sea of pollution, with dire consequences for Mauritius’ economy, food security and health."[14]
Reactions[edit]
Prime Minister Pravind Kumar Jugnauth declared a "state of environmental emergency" and requested French help on 7 August.[15] "When biodiversity is in peril, there is urgency to act," French President Emmanuel Macron tweeted, "France is there. Alongside the people of Mauritius. You can count on our support dear Jugnauth."[16] France sent both military and civilian equipment and personnel from its overseas territory of Réunion.[14]
Local volunteers joined forces to remedy the situation by making cloth barriers stuffed with straw and human hair.[17] Japan sent a six-member crew of specialists to help in the cleanup.[11] On 11 August 2020 Indian Oil (Mauritius) Ltd (IOML) started to evacuate fuel oil from the breached vessel Wakashio onto the IOML barge Tresta Star which has a capacity to hold 1,000 tonnes of the hydrocarbons.[18]
Environmental damage[edit]
Oceanographer and environmental engineer Vassen Kauppaymuthoo said, "Around a little bit less than 50 percent of this lagoon is covered by environmentally sensitive areas, be it corals, be it seagrass, be it mangroves, be it entire mudflats, sand beaches and dunes, which is huge. Which confirms the sensitivity of this lagoon, in terms of oil spill." Ecotoxicologist Christopher Goodchild from Oklahoma State University said, "With this oil spill it looks like there is infiltration out of the mangroves, so you have the oily substance that can bind to organic matter or dirt and start to settle in and just being able to remove that toxic sediment can be a real challenge."[19] Flakes of the damaged anti-fouling coating on the hull can also poison the marine fauna and flora on the reef and surroundings in a similar fashion to what occurred on the Great Barrier Reef.[20]

概要[編集]
わかしおは2007年5月に竣工したパナマ船籍（便宜置籍）のばら積み貨物船（ケープサイズバルカー）で、OKIYO MARITIME COPR.（長鋪汽船（岡山県笠岡市）の関連会社）が所有し商船三井が傭船して運航していた[1][2]。わかしおは積み荷を積載せずに中国の連雲港を現地時間2020年7月4日に出航し、シンガポール経由でブラジルのトゥバラン港（ポルトガル語版）に向かっていた[3][4]。インド洋を航行していたわかしおは、現地時間7月25日夜にモーリシャス南東部沖ラムサール条約の指定地域に含まれているポワント・デスニー（フランス語版）付近でサンゴ礁に乗り上げ座礁した[5]。商船三井は8月9日の会見で、座礁の原因について「（モーリシャス島の南方約20マイルを通る予定だったが）悪天候による強い風やうねりで北方へ押し流された可能性がある」としている[6]。この座礁の際に船体を損傷したと見られていて[7]、2週間後の8月6日朝には燃料タンクに亀裂が入り、重油1000トン余りが流出した[8]。
世界有数の美しいサンゴ礁を誇るモーリシャスは、食料面でも観光業でも海に大きく依存している。流出した重油はモーリシャスの生態系を破壊し、モーリシャスの経済や食料安全保障、健康にも深刻な影響を及ぼすことが懸念されていて、この事故を受けモーリシャスのジュグノート（英語版）首相は8月6日に環境緊急事態宣言を発出した[5][9]。
