MAN: ME-GI adds ethane to fuel portfolio

July 22, 2014

Ocean Yield ASA, the Oslo-based shipowner, has placed orders for three LEGCs (Liquefied Ethylene Gas Carriers) of 36,000 cbm capacity, to be built at Sinopacific Offshore & Engineering, China.

Each vessel will be powered by a single MAN B&W ME-GI low-speed, dual-fuel engine. The engines will run on ethane, which ethylene carriers are also equipped to transport, and represents the first time ethane has been used as fuel to propel an oceangoing vessel.

Hartmann Schiffahrt, part of Hartmann AG, the German ship-owning and management group, has acted as the technical leader on the LEGC project, while Gaschem Service, another Hartmann division, is commercially responsible for the employment of the vessel. The vessels are scheduled for delivery in August, October and December 2016 respectively.

MAN Diesel & Turbo reports that ethane was chosen as the fuel, in preference to HFO, due to its more competitive pricing as well as the significantly shorter bunkering time it entails. As a fuel, its emissions profile is also superior to HFO – in which respect it is similar to methane – and compared to HFO contains negligible sulphur, 15-20% lower CO2and emits significantly fewer particles under combustion. MAN Diesel & Turbo also states that the ME-GI engines will be set up such that they can easily be converted to run on methane as an alternative, as per the owner’s wish.
