we would like to share update information that the Maritime and Port Authority of Singapore (MPA) has carried out an investigation and has published their findings on their website.
MPA was notified on 14 March 2022 that a number of ships had been supplied with High Sulphur Fuel Oil (HSFO) containing high concentration levels of Chlorinated Organic Compounds (COC) (1,2-Dichloroethane, Tetrachloroethylene) in the Port of Singapore. MPA has conducted investigations and identified the source of the contamination.
The HSFO containing high concentrations of COC was traced back to fuel purchased by Glencore Singapore Pte Ltd (Glencore) in January and February 2022. Glencore had purchased the fuel through Straits Pinnacle Pte Ltd (Straits Pinnacle), which had contracted its supply from Unicious Energy Pte Ltd (Unicious). The contaminated HSFO was loaded at the Port of Khor Fakkan, United Arab Emirates (UAE) onto a tanker and shipped to floating storage facilities in Tanjong Pelepas, Malaysia to be further blended. The blended HSFO was subsequently delivered to storage facilities in Singapore. Part of the blended HSFO was also sold by Glencore to PetroChina International (Singapore) Pte Ltd (PetroChina).
MPA tested fuel samples taken from various sources and storage facilities Fuel onboard the tanker was found to contain high concentrations of COC, of up to 21,000 ppm.
All MPA-licensed bunker suppliers are required to test the fuel to ensure that it complies with international standards. MPA has established that both Glencore and PetroChina, as MPA-licensed bunker suppliers, had carried out tests on the fuel supplied based on the international standards of petroleum products of fuel - International Organization for Standardization 8217 (ISO 8217). However, as the current international standards do not require tests for COC, the contamination was not promptly detected.
MPA has not received any report of fuel containing high COC supplied by the same suppliers since 31 March 2022.
As a global bunkering hub, MPA takes bunker quality assurance seriously. MPA’s quality fuel assurance measures comprise the Bunker Quality Inspection System (BQIS) and the Intensified Bunker Quality Checks (IBQC). The BQIS tests the quality of bunker supplied to vessels while the IBQC tests bunker carried by bunker tankers before supply to vessels.
On average, over 1,300 bunker samples are tested annually under BQIS and IBQC to verify compliance with ISO 8217. While the occurrence of COC is rare in bunkers, MPA will include COC to the list of chemicals to be tested under both BQIS and IBQC with immediate effect.
MPA and the Singapore Shipping Association (SSA) are currently in discussions with the industry on measures to strengthen the quality assurance of bunkers supplied in Singapore. MPA and SSA will co-chair an industry expert group, which will include relevant professional bodies, to establish a list of chemicals to be tested and their corresponding concentration limits. The expert group is expected to make its recommendations on additional measures to strengthen bunker quality assurance of bunkers delivered in Singapore, on an urgent basis.
MPA has also raised this issue at the international level. At the recent International Maritime Organization Maritime Safety Committee (MSC105) working group meeting on ‘Measures to enhance safety of ships related to use of fuel oil’ held between 20 and 29 April 2022, MPA has informed the meeting that a paper on the recent contamination case will be submitted in due course for Member States’ awareness.
