SINGAPORE — The largest oil spill in Singapore waters was on Oct 15, 1997, when over 28,000 tonnes was spilled following a collision between Cyprus-registered tanker Evoikos and Thai-registered crude-oil tanker Orapin Global 5km south of Pulau Sebarok, which lies between the Raffles Lighthouse and Sentosa island. According to the Maritime and Port Authority, the operation led by the MPA and involving 16 ministries and agencies, the Singapore Armed Forces, oil terminals, salvage companies and oil spill response companies was cleaned up in a record time of three weeks. The waters around Pulau Bukom, Pulau Senang, Pulau Pawai and Pulau Sudong looked like a sea of black coffee as a result of that spill, according to Singapore Infopedia. The last major oil spill in Singapore waters before today was on May 25, 2010, when an estimated 2,500 tonnes of crude oil was spilled into the sea in the same area when Malaysian-registered tanker MT Bunga Kelana 3 collided with Grenadines-registered bulk carrier MV Waily off the Changi Naval Base at around 6am. Clean-up efforts were led by the National Environment Agency. Oil patches were seen at on stretches of the coast between the naval base and the Tanah Merah Ferry Terminal, as well as between the National Sailing Centre and the NSRCC-Safra Resort.
