SINGAPORE - JL Petroleum Pte Ltd has been fined by Singapore after pleading guilty in court to supplying marine fuel in the world’s top bunkering hub without a valid license, the Maritime and Port Authority of Singapore (MPA) said in a statement on Wednesday. MPA had brought charges against JL Petroleum for supplying marine fuel, also known as bunker, on 14 occasions between June 2 and June 25 in 2013, it said. JL Petroleum executives were not immediately available to comment. All bunker suppliers operating in the Port of Singapore have to obtain a license from the MPA. There are currently 59 licensed bunker suppliers in Singapore, down from around 65 suppliers last year, according to the MPA website.
