Liquid Petroleum Gas (LPG) has been given a boost as another 2020 option after MAN's LPG-fuelled ME-LGIP engine was selected to power a Chinese VLGC
Jiangnan Shipyard, owned by China State Shipbuilding Corp (CSSC), has ordered an LPG-burning MAN B&W 6G60ME-LGIP engine in connection with the building of an 86,000m3 VLGC (Very Large Gas Carrier) for Tianjin Southwest Maritime (TSM), the Chinese shipping company. Vessel delivery is scheduled for the second half of 2021 and includes an option for a second vessel, MAN said in a press release.
The Diesel principle provides the ME-LGIP engine with high operational stability and efficiency, including during load changes and fuel change-over, while defining properties such as a stable change-over from one fuel type to another with no fuel penalties are maintained. The negligible gas slip of the ME-LGIP engine makes it the most environmentally friendly, two-stroke technology available. The company also reports that the ME-LGIP engine has experienced an up to 18% reduction in CO2 and circa 90% reduction in particulate matter when running on LPG, compared with HFO. MAN Energy Solutions expects a strong demand for the ME-LGIP engine for VLGCs and coastal vessels.
MAN Energy Solutions already won a first order for the new engine earlier in 2018 when Hanjin Heavy Industries announced that it would construct two VLGCs in their Philippines Facilities for Exmar, the Belgian integrated gas-shipping company. The 86,000 m3 newbuildings will each be powered by an individual MAN B&W 6G60ME-LGIP Mk9.5 engine.
The company also announced the first retrofit orders for the ME-LGIP in September 2018 when it signed a contract with Oslo-listed BW LPG for the world’s first retrofitting of four MAN B&W 6G60ME-C9.2 HFO-burning engines to 6G60ME-C9.5-LGIP LPG-propelled dual-fuel engines. The order includes options for further retrofits in the future with work expected to begin during 2020.
Bjarne Foldager – Senior Vice President, Head of Two-Stroke Business at MAN Energy Solutions – said: “With 2020 and the new IMO emissions fast approaching, interest in using LPG as a fuel – within and outside of the LPG carrier segment – is growing due to its sulphur-free character, widespread availability, price competitivity, and ease of bunkering. At MAN Energy Solutions, we feel that the introduction of the ME-LGIP is proving timely.”
Foldager added: “In gas mode, the ME-LGIP engine operates on just 3% pilot oil and down to 10% load. Ultimately, we expect the engine to operate without the need for pilot oil. The ME-LGIP can also burn liquid volatile organic compounds, a deliberate move on our part since the IMO will inevitably turn its focus towards the reduction of volatile organic compounds in the future. Accordingly, we view the ME-LGIP as also ideally suited to the propulsion of shuttle tankers and very large crude carriers.”
