The Maritime and Port Authority of Singapore (MPA) said it had been informed of an oil spill off Changi during a bunkering operation between a Bahamas-flagged container vessel and a licensed bunker tanker.

The incident was reported to have occurred on October 28 in the afternoon, and the bunkering operations ceased immediately.

It said that relevant government agencies have been alerted to keep a lookout for any oil sightings along the shores.

"There is no impact to navigational traffic," MPA added, noting that further updates will be provided when available.

MPA also confirmed that oil which overflowed during a bunkering operation from the receiving Bahamas-flagged Bulk Carrier, INES CORRADO, had stopped.

It said that an estimated 5 tonnes of oil was reported to have overflowed, but MPA patrol craft had sprayed dispersants.

As of 8:00 a.m. on October 29, MPA said no oil had been sighted at sea or ashore in the vicinity of the incident.

"As a precautionary measure, a Current Buster has been deployed off Changi to recover oil on water if sighted," it added, noting that MPA has also alerted Malaysian authorities to keep a lookout for oil sightings.
