Interest in scrubber retrofits is growing as the difference in price between low and high-sulphur bunkers explodes, according to Tamara de Gruyter.

The president of marine systems at exhaust cleaner manufacturer Wartsila said the situation is “looking good”.

The price differential is approaching $600 per tonne between high-sulphur fuel oil (HSFO) and very low-sulphur fuel oil (VLSFO), TradeWinds has reported.
