The Maritime and Port Authority of Singapore (MPA) has revoked the bunker craft operator licence of Inter-Pacific Petroleum Pte Ltd as of October 15, effectively disallowing it to operate in the Port of Singapore.

"As part of MPA’s ongoing efforts to ensure the integrity of bunkering in Singapore, checks were conducted on Inter-Pacific earlier this year," MPA said in a statement.

It noted that during the checks and subsequent investigations, the port authority found magnetic interferences affecting measurements of bunkers supplied in numerous Mass Flow Meter readings across Inter-Pacific’s fleet of bunker tankers.

MPA said that Inter-Pacific had also failed to ensure that its employees, including its cargo officers, comply with the terms and conditions of its licence.

The latest move comes after MPA temporarily suspended the license of Inter-Pacific last June.

"MPA reminds all bunker licensees to adhere strictly to the terms and conditions of their licences. MPA will take firm action against any licensee who has acted in contravention of its licence(s), including the suspension or revocation of licence(s) where necessary," it added.
