LNG Propulsion Guide

Liquefied Natural Gas propulsion offers significant reductions in sulphur oxide and nitrogen oxide emissions compared to heavy fuel oil. Modern dual-fuel engines can operate on either LNG or marine diesel, providing flexibility while meeting IMO Tier III requirements.

Dual-Fuel Technology

High-pressure dual-fuel engines operating on the diesel cycle inject gas directly at high pressure. This achieves diesel-like efficiencies and is used by systems like the MAN B&W ME-GI engine found on many large container ships and LNG carriers.
