Why SCR or EGR on LNG Carriers?

EGR or SCR needed on ME-GI for Tier III NECA Gives full fuel flexibility in Tier III NECA. Low Sulphur HFO Fully valid option in SECA. No operational Limitations: When empty LNG tanks are required. When the ship is going to a yard. In case of gas malfunction Full redundancy in fuel choice.

SCR for Tier III NOx control High Pressure and Low pressure SCR


EGR for Tier III NOx control Impact of reduced Fuel Sulphur

Low sulphur → Less sulphur oxides in exhaust Compacting the EGR unit Smaller collecting tank Lower NaOH consumption →

Reduced tank capacity Scrubber element removed

Low sulphur → Less particulate matter in

exhaust Lower sludge accumulation →

Reduced tank capacity Other technologies?


EGR SCR

Deciding factors:

Yard preferences First cost (CAPEX) Space requirements Installation flexibility

Owner preferences Operation cost (OPEX) Operation simplicity Reliability Maintenance cost & simplicity Waste disposal cost

Selection of Tier lll Technology


MAN B&W is Leading Tier III Technologist

SCR and EGR proven in service.

Developed for different scenarios: Primarily for max. 0.1 % sulphur in fuel For heavy fuel for Tier III compliance

and later for Tier II compliance with fuel saving potential

OG-LS 3339448.2014.05.07

30 bore - 46 bore

SCR preferred solution EGR alternative solution

50 bore - 70 bore Both solutions recommended

80 bore - 95 bore

EGR preferred solution SCR alternative solution HP SCR difficult beyond eight cylinders

Both methods are commercially available now.

General Recommendation for Tier III SCR and EGR
