MAN Diesel & Turbo and Hyundai Heavy Industries Engine & Machinery Division (HHI-EMD) have agreed to develop a dual-fuel, two-stroke engine capable of burning liquefied petroleum gas (LPG).
Vessel operators are looking to cleaner fuels — including LPG and liquefied natural gas (LNG) — as the 2020 0.5% fuel sulphur cap approaches. But unlike other gaseous fuels, LPG does not require a large investment in bunkering infrastructure.
According to a statement from MAN, LPG carriers have called for the company to develop an LPG-fuelled engine that could power their vessels in the most viable, convenient and economical way using a fraction of the LPG cargo already onboard.
MAN expects that the engine that results from its partnership with Hyundai will be cost-competitive compared to other dual-fuel-burning engine types.
“MAN Diesel & Turbo has previously experienced strong market interest in using LPG as a fuel aboard LPG carriers, but other shipping segments have also begun investigating this option, a general tendency that is growing,” says Bjarne Foldager, vice president sales & promotion, Two-Stroke Business at MAN Diesel & Turbo.
“LPG holds great potential as a fuel since it contains no sulphur, is widely available, and easy to bunker. It is therefore becoming an increasingly attractive alternative to other, low-sulphur fuel types.”
