A further option for achieving IMO Tier III NOx emission compliance when operating on methanol fuel has been unveiled by MAN Energy Solutions. Methanol dual-fuel two-stroke engines of the ME-LGIM series will now be offered with selective catalytic reduction (SCR) technology.

Emission abatement using SCR will be made available alongside exhaust gas recirculation (EGR), the existing method of driving down NOx to Tier III criteria for all engines in the ME-LGIM programme.

The delivery of a broader choice is intended to suit owner or shipyard preferences, and individual considerations of operational expenses and capital expenditure.
