Scorpio Tankers stands to save between $100m and $125m in bunker fuel costs per year once exhaust-gas scrubbers are installed on 95 targeted vessels, the company is telling investors.

It is the first time Emanuele Lauro-led Scorpio has put a number on the expected returns from its scrubber programme, which would provide compliance for all but 14 smaller vessels in its fleet for the IMO 2020 sulphur emissions deadline on 1 January.
