The clean-up operation for the oil spill that resulted from a collision between the Thailand-registered freighter, MV Hermion and the Singapore-registered bunker tanker, Neptank VII, at 0145hrs about 4.5km south-east of Sentosa, has made good progress. Oil patches sighted by an aerial recce conducted from 0900hrs to 1100hrs have been cleaned up by the anti-pollution craft deployed by the Maritime and Port Authority of Singapore (MPA). The dispersant-treated oil patches (i.e. light oil sheens) were sighted in the waters about 5 km south and south-east of Bedok Jetty. There has been no report of the oil affecting any of the islands or mainland Singapore. The MPA has deployed oil booms off the waters of Marina Bay and Sentosa as a precautionary measure.
