The Maritime and Port Authority of Singapore, which oversees the world’s biggest marine refuelling hub, said it is investigating the suspected contamination of bunker fuel supplied to several ships in the port and had ordered supply of the batch to be halted.

At least 14 ships that received tainted high-sulphur fuel oil (HSFO) from Singapore suffered loss of power and engine problems, fuel and oil testing firm Veritas Petroleum Services (VPS) said late last week.

The authority said it was notified of the issue on March 14 and immediately contacted bunker suppliers to stop supplying the relevant batch of fuel, and to inform all ships supplied with the fuel to exercise caution when using it, according to an emailed statement late on Sunday.

“As a major bunkering hub, the Maritime and Port Authority of Singapore (MPA) takes quality assurance seriously and is investigating the cause of the alleged bunker fuel contamination,” it said.

“Further investigations are currently on-going. MPA will not hesitate to take action should there be any non-compliance.”

MPA did not name the suppliers. VPS had said that 34 vessels were identified as having received HSFO deliveries over the last two months that were contaminated with up to 2,000 parts per million (ppm) of chlorinated hydrocarbons.

Simon Neo, head of marine fuels consultancy SDE International Pte Ltd, said it was possible that contamination occurred in the blending process, while only a limited group of users appeared to be affected.

“All fuel oil in Singapore – be it high sulphur, or low sulphur – are all blended,” Neo said, noting that the delivered HSFO met standard specifications.

“It’s affecting a couple of players only, but the rest of the suppliers so far haven’t got any of it,” he added.

Norwegian-headquartered ship insurer Skuld said on Friday that over the past two weeks it had seen an increased number of claims related to high-sulphur fuel oil loads at Singapore, which were found to be contaminated with chlorinated compounds.

Another ship insurer, Gard, which said it experienced a few severe cases of main engine breakdown, also flagged similar issues.

“In some cases, the vessels even required a tow to port,” Gard said.
