SINGAPORE: The oil leak at Shell's refinery at Pulau Bukom has stopped and clean-up of oil sheens spotted off the island has been completed, government agencies said in a joint statement on Saturday (Dec 28).
Shell previously said that some of its refined oil products were released into the water due to a suspected leak at an oil processing unit on Pulau Bukom.
Oil sheens were spotted alongside a wharf on Dec 26 at the Shell Energy and Chemical Parks, prompting authorities to put containment measures in place.
It was estimated that a few tonnes of refined oil products were leaked, together with the cooling water discharge.
No more oil was observed going into the cooling water discharge channel after Shell shut down its oil processing unit on Friday, the Maritime Port Authority of Singapore (MPA), the National Environment Agency (NEA), the National Parks Board (NParks) and Sentosa Development Corporation (SDC) said on Saturday.
"Efforts by Shell to locate the source of the leak in the oil processing unit are ongoing," they added.
Giving a timeline of events, the government agencies said on Saturday that the oil sheens were discovered by Shell at around 9.30am on Thursday, and were reported to MPA and NEA at 11.58am and 1.15pm respectively.
An MPA craft reached the site of the incident at 12.15pm to assess the situation and to provide support.
"Initial assessments on Dec 26 determined the scale of oil sheens to be minor, with no risk to public safety or environmentally sensitive areas, given the containment measures Shell had implemented," the agencies said.
Shell laid containment and absorbent booms and sprayed dispersants in the channel where the cooling water is discharged.
MPA deployed three patrol craft on Friday when Shell requested support to speed up the cleaning of the oil sheens off Pulau Bukom.
There have been no sightings of oil sheens or oil patches in the waters off Sentosa, and its beaches remain open for water activities, said the agencies.
However, as a precaution, oil-absorbent booms have been laid at Sisters' Islands Marine Park and at the beaches on Sentosa.
"NEA is investigating the incident with MPA, and actions will be taken if any wrongdoing or lapse is discovered," said the agencies.
