Norway’s Knutsen OAS Shipping has ordered four MAN B&W 5G70ME-GI engines with exhaust gas recirculation (EGR) systems in connection with the construction of two 180 000 m3 liquefied natural gas (LNG) tanker newbuildings.
Upon delivery in 2020, the vessels will transport cargoes worldwide for two Spanish utility companies. MAN said the order follows the increasingly popular path initiated by Gas Natural Fenosa, the multinational Spanish group that was the pioneer in adopting ME-GI technology in an order for four LNG tankers in 2013.
“These orders are notable in that they are the sixth and seventh such carriers bound for service for Spanish utilities that have been ordered within the past four years alone,” said Bjarne Foldager, vice president Sales & Promotion, Two-Stroke Business at MAN Diesel & Turbo. “As such, our G70ME-GI engine has become a popular choice for LNG carriers globally. This can be attributed in great part to the ME-GI’s embracing of the Diesel principle, which is simply the most effective method of converting gas fuel to propulsion power.”
The new orders stem from Corpus Christi Liquefaction, LLC – a subsidiary of Cheniere Energy, Inc., that recently entered into 20-year LNG sale and purchase agreements (SPAs) with the two Spanish utilities. Under the terms of their respective SPAs, the Spanish utilities have agreed to purchase a combined total of over 1 million tons per annum of LNG upon the commencement of operations from the LNG export facility currently being developed near Corpus Christi, Texas, USA.
MAN said the ME-GI dual-fuel low-speed diesel engine represents the culmination of many years of development work. Depending on relative price and availability, as well as environmental considerations, the ME-GI engine gives shipowners and operators the option of using either HFO or gas – predominantly natural gas.
MAN Diesel & Turbo sees significant opportunities arising for gas-fueled tonnage as fuel prices rise and modern exhaust-emission limits tighten. Indeed, research indicates that the ME-GI engine delivers significant reductions in CO2, NOx and SOx emissions. Furthermore, MAN said the ME-GI engine’s negligible methane slip makes it the most environmentally-friendly technology available. As such, the ME-GI engine represents a highly efficient, flexible, propulsion-plant solution, the company said.
In May 2017, an ME-GIE variant passed operational tests running on ethane, while an ME-LGI counterpart to the ME-GI that runs on LPG, methanol and other liquid gasses has also successfully been introduced to the market.
