The ''Rena'' oil spill occurred off the coast of Tauranga in New Zealand. The spill was caused by the grounding of 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, and chartered by the Mediterranean Shipping Company (MSC). The spill has been described as New Zealand's worst maritime environmental disaster. ==Sequence of events== On Wednesday, 5 October 2011, at 2:20 AM (Tuesday, 4 October 13:20 UTC) while sailing in clear weather from Napier to Tauranga, and with a speed of , ''Rena'' ran aground on the Astrolabe Reef. The ship was carrying 1,368 containers, eight of which contained hazardous materials, as well as 1,700 tonnes of heavy fuel oil and 200 tonnes of marine diesel oil. Initially the ship listed 11 degrees to port, with the front stuck on the reef.〔(【引用サイトリンク】title=Maritime NZ Update: Tue 11 Oct - Rena rotates through 25 degrees )〕 By Sunday, 9 October 2011, a oil slick threatened wildlife and the area's rich fishing waters. Oil from ''Rena'' began washing ashore at Mount Maunganui beach on 10 October 2011. Bad weather that night had caused the ship to shift onto the reef, and the crew was evacuated. The shifting of the ship caused further damage, resulting in a further 130 - 350 tonnes of oil leaking.〔 Strong winds and bad weather on the night of 11 October 2011 caused the ship to list over to starboard 19 degrees; this resulted in between 30 and 70 containers being washed overboard. None of the containers contained hazardous cargo.〔 Containers subsequently began washing ashore on Motiti Island. On the afternoon of 12 October 2011, aerial footage showed a large crack in the hull of ''Rena'', increasing fears that the ship could break in two and sink. It also showed a container floating in the water surrounded by smoke, suggesting that a chemical reaction was occurring.〔 On 13 October 2011, Maritime New Zealand ordered beaches from Mount Maunganui to Maketu Point, including the Maketu Estuary, to be closed to the public. Volunteers were warned that contact with spilled oil could lead to vomiting, nausea and rashes, and local residents were urged to close their windows to limit fumes. Costamare Shipping, the owners of ''Rena'', apologised to the people of Tauranga, saying they were "deeply sorry" for the "disastrous event." Although not legally obligated to do so, the charterer, Mediterranean Shipping Company, promised to help with the cleanup costs. On 14 October 2011, it was reported that the ship had cracked completely in half, and was held together only by her internal structure and the reef. Calmer weather meant that preparations could be made to pump out the remainder of the ship's oil,〔 but a change in the wind direction meant that oil was likely to spread as far east as Whakatane and Opotiki. Also on 14 October 2011, the Filipino crew of the ''Rena'' left New Zealand "for their safety" after a racist backlash against Filipinos in Tauranga. Calm weather on 15 October 2011, allowed salvage experts to board the vessel and begin preparations to pump the remaining oil to a barge. Platforms were attached to the side of the ship, and pumping began on 16 October 2011. By 17 October only twenty tons of oil had been removed. On 16 October a mine-countermeasures team aboard HMNZS ''Manawanui'' began hunting for containers spilled from the ''Rena''. After October, salvage efforts were focused on removing the ship's cargo before it completely broke apart. In January 2012, the ''Rena'' completely broke in half and the stern slipped off of the reef and began sinking. A small amount of oil and containers escaped the ship as it broke in half. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Rena oil spill」の詳細全文を読む スポンサード リンク
