Singapore’s Maritime and Port Authority (MPA) said it has identified Glencore Singapore Pte as the supplier of contaminated fuel, which has caused technical problems in up to 80 ships.

The MPA said following its investigation into reports of contamination it had identified high concentrations of chlorinated organic compounds (COC) dichloroethane and tetrachloroethylene in blended high-sulphur fuel oil (HSFO) bunkered at its port.

Singapore is the world’s largest bunker supply port.
