AP Moller-Maersk is reported to be suing commodities trader Glencore over the alleged sale of contaminated bunkers in 2018.

The Danish shipping giant bought the fuel in a deal that saw the two companies swap 24,000 gallons of bunkers at two different terminal locations in Panama, Bloomberg reported.

Maersk claimed the off-spec fuel had caused engine failure on board the 9,600-teu containership Sofie Maersk (built 1998).
