Scorpio Tankers is predicting a boost to product carrier tonne-miles as inefficient older refineries are closed.

About 14 plants face closure worldwide this year and in 2021, the world's biggest clean tanker company said in a presentation to investment bank Fearnley Securities.

One specific case mentioned was BP's decision to end production at its 146,000 barrel per day (bpd) Kwinana refinery in Australia at the end of 2020.
