SINGAPORE-- The Maritime and Port Authority of Singapore (MPA) has revoked the bunker craft operator licence of Panoil Petroleum Pte Ltd with effect from today.

In a statement here, the Authority said Panoil Petroleum will no longer be allowed to operate as a bunker craft operator in the Port of Singapore.

As part of MPA's on-going regulatory efforts to ensure the safety, reliability and quality of bunker supplies in Singapore, checks were conducted on Panoil Petroleum between January and March 2017.

MPA's checks revealed that unauthorised alterations were made on board five bunker tankers operated by Panoil Petroleum.

The unauthorised alterations were made on the pipelines of the bunker tankers between the Mass Flow Meters (MFM) and the flow boom.

Such alterations allow bunker fuel that have been measured by the MFM to be siphoned out and undermines the accuracy of the readings from the MFM system, it said.

MPA said the unauthorised alterations breached the terms and conditions of Panoil Petroleum's bunker craft operator licence.

MPA reminded all licensed bunker suppliers and bunker craft operators to adhere strictly to the terms and conditions of their bunker licences.

MPA said it will take firm action against any licensee who acted in contravention of their licences, including suspending or revoking their bunker licences.
