Danish bunker and tanker group Monjasa has seen profit dip in 2018 despite a big rise in fuel volumes.
It said there had been a 17% increase in the amount of bunkers sold last year at 4.1m tonnes.
Net earnings were $5m, down from $7m last year, however.
"The positive developments of more customers buying more bunkers are not completely evident on the bottom line due to some non-recurring costs in the beginning of the year," it told TradeWinds.
