Dual-fuel two-stroke engine order for LNG carriers
MAN Diesel & Turbo has reported a contract for four MAN B&W 5G70ME-GI engines to power two LNG carriers, ordered by Norway’s BW Group from Daewoo Shipbuilding & Marine Engineering.
The engines will be supplied to IMO Tier II specification, but with the option to be able to fit equipment at a later stage to ensure Tier III compliance. Tier III requires a considerable reduction in NOx emissions – according to MAN a reduction of 80% within ECAs compared to Tier I – and this can be achieved on the ME-GI engine by fitting either selective catalytic reduction (SCR) or exhaust gas recirculation (EGR). Which solution is better will depend on factors such as distances travelled within ECA zones as a percentage of total ship usage, different ownership models or different engine-operation profiles.
The 173,400 m³ vessels are scheduled for delivery in late 2017/early 2018 and will be built at DSME’s Okpo shipyard in Geoje, Korea. The deal represents the second LNG ME-GI contract for DSME after a previous order signed in 2012. It was recently announced that these ships will have GTT’s cargo containment systems.
Although other two-stroke dual-fuel technologies are available that allow Tier III compliance without after-treatment, MAN says that the ME-GI’s high-pressure gas injection allows it to maintain the numerous positive attributes of oil-fuelled low-speed engines.
