MAN Energy Solutions has signed a contract for the conversion of a 15,000 TEU container vessel to dual-fuel LNG operation.

The container vessel MV SAJIR is owned by Hapag-Lloyd, one of the world’s leading liner shipping companies, and normally serves a route from Asia to northern Europe via the Suez canal. The pilot project will entail the conversion of an existing, HFO-burning MAN B&W 9S90ME-C engine to a dual-fuel MAN B&W ME-GI (-Gas Injection) prime mover capable of running on HFO and LNG.

The retrofit will take place at the Chinese Hudong/HRDD shipyard, specialized in ship repair and conversion.

Hapag-Lloyd announced last month it will retrofit its 15,000 TEU ‘megaship’ Sajir to cleaner burning LNG fuel, becoming the first in the world to convert a ship of this size to LNG propulsion.

“We are seeing great interest in this project from the industry as a whole,” said Wayne Jones OBE, Chief Sales Officer and Member of the Executive Board at MAN Energy Solutions. “This is an excellent showcase for the conversion of a mega-container vessel to LNG and the potential benefits for the market is huge. With this announcement, MAN Energy Solutions is once again at the forefront of technology with our ability to execute LNG conversions for both four-stroke and two-stroke engines.”

Using LNG in the shipping industry could reduce CO2 emissions by 15 to 20 percent and sulphur dioxide and particulate matter by more than 90 percent.

“By converting the ‘Sajir’, we will be the first shipping company to retrofit a container ship of this size to LNG propulsion”, said Richard von Berlepsch, Managing Director Fleet Management at Hapag-Lloyd. “With this unprecedented pilot, we hope to learn for the future and to pave the way for large ships to be retrofitted to use this alternative fuel.”

The Hapag-Lloyd pilot project is scheduled to take place in 2020 when the five-year old vessel will spend 90 days in dock. The DNV-GL approved gas-storage system will occupy an area equivalent to 350 containers, including the pipework between storage and engine.

MAN Energy Solutions took over fuel-gas specialist company Cryo AB in 2015 and fully integrated it into its business. Under the brand MAN Cryo, the company offers systems for the storage, distribution and handling of liquefied gases.

In respect to four-stroke, Jones is referring to the 2017 conversion of Wessels Reederei’s ‘Wes Amelie’, a 1,036-teu container ship that was originally fitted with an MAN 8L48/60B diesel engine. Upon conversion to a dual-fuel MAN 51/60DF unit, the ‘Wes Amelie’ reported significantly changed emissions. The vessel now meets both the Tier II and Tier III emission requirements set by the International Maritime Organisation (IMO).
