Scrubber Retrofits ‘Three Times’ Cheaper Than LPG Engines

Upgrading the VLGC main engines to dual fuel technology using LPG would cost more than three times that of retrofitting scrubbers.
The readily available and lower-priced 3.5% HSFO only requires scrubbers on ships and does not need operational changes.
The 0.1% and 0.5% low sulphur fuel oil will require tank cleaning, which is not readily available and has no ISO standard.
Alternative fuels such as LNG, LPG and ethane, require newbuilding, or can be used with engine retrofitting for dual fuel.
