Shell Singapore has been formally charged over two oil pollution incidents at its Pulau Bukom refinery, including allegations that the company failed to report the discharges to Singapore authorities without delay.
The charges, filed on 22 September 2026 under Singapore’s Prevention of Pollution of the Sea Act, relate to separate incidents in October and December 2024 at the Shell Singapore Energy and Chemicals Park on Pulau Bukom.
According to Channel NewsAsia, the first incident involved approximately 40 tonnes of oily mixture being discharged into Singapore waters through a hole in a pipeline within Shell’s refining facility at about 8am on 20 October 2024. (CNA)
The charge alleges that Shell did not notify the port master until approximately 12.55pm that day. (CNA)
That timing is potentially important because Singapore regulations require operators of such facilities to report pollution incidents without delay and to the fullest extent possible.
A second leak two months later
The prosecution also concerns a second pollution incident over the Christmas period of 2024.
According to the charges reported by CNA, an estimated 485kg to 956kg of oil mixture entered Singapore waters from the Pulau Bukom facility between approximately 9.30am on 26 December and 8.30am on 28 December 2024. (CNA)
Shell is again accused of failing to report the incident immediately.
The December incident had already attracted regulatory attention at the time. Singapore’s Maritime and Port Authority and National Environment Agency announced on 27 December 2024 that Shell had shut down an oil-processing unit while the suspected leak was investigated.
Shell estimated at the time that a few tonnes of refined petroleum products had leaked together with cooling-water discharge. Containment booms, absorbent material, dispersants and an oil-skimming system were deployed, while government agencies used boats, satellites and drones to monitor the surrounding waters. (MPA)
Precautionary booms were also deployed at locations including the Sisters’ Islands Marine Park and Sentosa.
The October 2024 incident
The earlier October incident had involved what authorities described at the time as a leak from a Shell land-based pipeline between Bukom Island and Bukom Kecil.
The Maritime and Port Authority said on 20 October 2024 that it had been alerted at about 1pm to a leakage that had occurred at approximately 5.30am that morning. Shell deployed containment booms and vessels equipped with dispersants, while MPA deployed additional craft, drones and satellite surveillance. (MPA)
By the end of that month, Singapore authorities said the clean-up of the leaked material — described as “slop”, an oily mixture — had been completed and that no further oil sightings had been observed at sea or ashore. Investigations nevertheless remained ongoing. (MPA)
The significance of the latest development is that those investigations have now resulted in charges.
Shell asks for more time
At the 22 September court hearing, a Shell representative reportedly requested an eight-week adjournment.
According to CNA, the company said it needed time to obtain internal instructions, appoint legal counsel and locate historical records.
One complication is that the business associated with the incidents was divested in 2025, according to Shell’s representative. The company therefore said additional time would be necessary to retrieve and examine the relevant historical material before responding to the allegations. (CNA)
The proceedings were adjourned until October.
CNA also reported that Shell faces a separate prosecution by Singapore’s National Environment Agency concerning the same incidents. (CNA)
Potential penalties
The penalties are not insignificant.
According to CNA, an entity convicted as the occupier of land from which oil or an oily mixture is discharged into Singapore waters may face a fine ranging from S$1,000 to S$1 million.
A failure to report such a discharge without delay and to the fullest extent possible can attract a further fine of up to S$5,000. (CNA)
These are charges, not findings of guilt. Shell has not yet presented its substantive response to the allegations, and the issues will now proceed through Singapore’s judicial process.
From “top priority” to courtroom
There is, however, an uncomfortable contrast between the present charges and Shell’s public statements when the December 2024 leak occurred.
At the time, Shell said that the health and safety of its employees and protection of the environment were its “top priority”, while emphasising that it was cooperating with authorities and carrying out containment and clean-up operations. (CNA)
Nearly two years later, Singapore prosecutors are not merely examining how the oil escaped. They are also alleging failures in the way the incidents were reported.
That makes this more than another historical Shell spill story.
The court will have to determine whether the prosecution’s allegations are proved. But the existence of formal charges means that questions surrounding the Pulau Bukom leaks — including how the discharges occurred and how promptly Shell informed regulators — are now matters for judicial scrutiny rather than simply corporate explanation.
For a company that routinely emphasises its commitment to safety, environmental responsibility and regulatory compliance, that is a development worth watching closely.
