On LPG fuelling, Pontus Berg is convinced of one thing. “It will be cheaper than [other 2020] compliant fuel,” BW LPG’s head of technical and operations says. “I’m certain of that.”

He says LPG today is either cheaper or, at worst, on a par with heavy fuel oil and definitely priced lower than the 0.1% low-­­sulphur fuel oil used in emission control areas and sulphur emission control areas, as well as whatever new blends come out in 2020.
