Engine manufacturer MAN Diesel & Turbo has confirmed an order for the world’s first liquefied petroleum gas (LPG) powered dual-fuel engine.
Hanjin Heavy Industries will construct two 80,000 m3 capacity VLGCs (Very Large Gas Carriers) at their Philippines Facilities for EXMAR, the Belgian integrated gas shipping company. Each newbuilding be powered by an individual MAN B&W 6G60ME-LGIP Mk9.5 engine.
“Interest in using LPG as a fuel, outside of the LPG carrier segment, is growing due to its sulphur-free character, free availability and ease of bunkering,” says Bjarne Foldager – Vice President Sales & Promotion, Two-Stroke Business at MAN Diesel & Turbo.
“In gas mode, we expect the ME-LGIP engine to operate on just 3% pilot oil and down to 10% load. Ultimately, we expect the engine to operate without the need for pilot oil.”
According to MAN Diesel & Turbo, the VLGCs have chosen LPG as a fuel option so they can comply with the new IMO sulphur-emission legislation due to enter force in 2020.
There is an approximate 10% reduction in carbon dioxide (CO2) and 90% reduction in particulate matter when running on LPG, compared with marine diesel oil (MDO).
“LPG is an eminently environmentally-friendly fuel, in much the same class as liquefied natural gas (LNG), and an LPG-fuelled engine will significantly reduce emissions, enabling vessels to meet the stringent IMO SOx emission regulations due to come into force globally from 2020,” it says.
“LPG's future as a viable fuel for general marine transportation looks promising as it will not require as large an investment in infrastructure – such as bunkering facilities – in contrast to other, gaseous fuels.”
Engine delivery to the yard has been scheduled for December 2019.
