Conditions are not yet right for shipping's second scrubber boom despite the widening gap between high and low-sulphur fuel prices, according to Tamara de Gruyter, president of marine systems at Finnish technology company Wartsila.
But that day may come later this year if economies recover and there is greater consistency in the spread between the bunker types.
De Gruyter told TradeWinds that the number of retrofits of exhaust cleaning systems "really came down" during the last year.
