MARCH 29, 2016 — Crowley Maritime Corporation has marked another critical milestone in construction of its two LNG fueled ConRO ships with the setting of the MAN Diesel & Turbo 8S70ME-C8.2-GI main
The project involved retrofitting two MAN B&W S70ME-C HFO-burning engines in the chartered Q-Max vessel Rasheeda with gas-burning M-Type Electronically Controlled – Gas Injection (ME-GI) Systems, which have now been successfully commissioned.
The retrofit modification meets all current and foreseen global emissions regulations.
Nakilat-Keppel Offshore & Marine (N-KOM) carried out the conversion at its Erhama bin Jaber Al Jalahma Shipyard facilities in the major Qatari port of Ras Laffan Industrial City.
The project collaborators, including MAN PrimeServ, installed the ME-GI system on the vessel at the shipyard in June 2015. The partner for the ME-GI fuel supply system is TGE Marine Gas Engineering GmbH,
Christian Ludwig, Head of Retrofit and Upgrades, MAN PrimeServ, said: “This is a fantastic milestone in our company’s history. It is a lighthouse project, and there has been a remarkable partnership and cooperation through this historic conversion. Our ME-GI order book now stands at 140 orders – for different vessel sizes and applications, which we see as a compelling case for our technology to be designated the industry standard.”
Nakilat Managing Director Eng. Abdullah Al-Sulaiti, said, “The success of the ME-GI project is the culmination of years of cooperation with Qatargas, RasGas and MAN Diesel & Turbo as turnkey project manager. In late 2013, Nakilat worked with our charterers to implement a pilot conversion on Q-Max Rasheeda, the first retrofit ME-GI project ever to be implemented in the marine industry. This is a milestone moment for all involved parties.”
MAN Diesel & Turbo reports that the vessel’s ME-GI units have displayed a seamless change between fuel-oil and gas operation – a key characteristic of the ME-GI technology.
The Qatar fleet comprises 14 Q-Max and 31 Q-Flex LNG carriers, all using dual MAN Diesel Turbo’s S70-ME low-speed diesel engines for propulsion.
THE ME-GI ENGINE
The ME-GI engine gives shipowners and operators the option of utilizing oil or gas fuel depending on relative price and availability, as well as environmental considerations.
The ME-GI uses high-pressure gas injection, allowing it to maintain the attributes of MAN B&W low speed engines that have made them the default choice of the maritime community.
The ME-GI is not affected by the derating, fuel-quality adjustment or methane-slip issues that have been seen with other dual-fuel solutions.
MAN Diesel & Turbo sees significant opportunities for gas-fueled tonnage as fuel prices rise and exhaust-emission limits tighten. Research indicates that the ME-GI engine delivers significant reductions in CO2, NOx and SOx emissions, with its negligible methane slip makes it the most environmentally friendly technology available.
An ME-LGI counterpart that uses LPG, methanol and other liquid gases is also available and has already been ordered.
The engine is the first of two 8S70ME-C8.2-GI units for delivery to VT Halter Marine, Pascagoula, MS, for installation in the two 2,400 TEU ConRo ships it is building for Crowley Maritime Corporation.
The vessels will be two of the world’s first LNG-powered ConRo ships, with container Lift-on/Lift-off (LO/LO) and vehicle Roll-on/Roll-off (RO/RO) loading. Designed to travel at speeds up to 22 knots, they will be 219.5 m long, 32.3 m wide and have a deep draft of 10 m. In addition to carrying 2,400 TEU of containers they will be able to carry nearly 400 vehicles in an enclosed Roll-on/Roll-off garage.
Crowley ordered the ME-GI engines, along with three MAN 9L28/32DF auxiliary engines for each vessel, in early-2014. The company selected the high-pressure, Diesel-cycle ME-GI engines because of their high efficiency and power concentration. The ME-GI’s ability to avoid derating, and its negligible methane slip, also contributed to its selection.
Crowley reports that the newbuildings will reduce the amount of CO2 emissions attributable to each container by approximately 38%.
The ships will meet or exceed all regulatory requirements and will have the CLEAN notation, which requires limitation of operational emissions and discharges, as well as the Green Passport, both issued by DNV GL.
The ME-GI engine
The ME-GI engine is the culmination of many years’ work, and gives shipowners and operators the option of utilizing fuel or gas depending on relative price and availability, as well as environmental considerations.
The ME-GI uses high-pressure gas injection that allows it to maintain the numerous positive attributes of MAN B&W low-speed engines that have made them the default choice of the maritime community. The ME-GI is not affected by the multiple de-ratings, fuel-quality adjustments or large methane-slip issues that have been seen with other dual-fuel solutions.
MAN Diesel & Turbo sees significant opportunities ahead for gas-fueled tonnage as fuel prices rise and exhaust emission limits tighten. Research indicates that the ME-GI engine delivers significant reductions in CO2, NOx and SOx emissions. Its negligible methane slip makes it even more environmentally friendly
An ME-LGI counterpart that uses LPG, methanol and other liquid gases is also available, and has already been ordered.

TGE Marine is a leading provider of engineering services for the design and supply of gas carriers, fuel gas systems and offshore units. Its deliver turnkey solutions for engineering, design, procurement and construction supervision (EPCS) of marine gas handling and storage systems as well as vessel designs. It specalizes in the containment and handling of cryogenically stored gases and is a market leader in the ethylene carrier and small LNG carrier segment.
It is a pioneer in LNG fuel gas systems and LNG bunkering. Most of its customers are commercial shipyards that build gas carriers.
MES says that with the demand for small-to-medium sized carriers for LNG, ethane and ethylene gas, and LPG expected to increase it is currently engaged in the development and sale of medium sized multi-gas carriers. And with the increasing focus on environmentally friendly marine fuel, it has been engaging in the development and sale of electronically-controlled dual fuel gas injection diesel engines (ME-GI) and high-pressure compressors for fuel gas supply systems that can use not just heavy oil, but also natural gas as fuel.
The technology and the engineering and construction knowhow and strong customer bases at both MES and TGE are expected to be highly compatible with each other and, by bringing all of this together, MES believes the two companies will be able to establish an excellent market position in the global small-to-medium sized gas carrier market and offer high value-added solutions to their customers. Furthermore, MES offering its core gas fuel products, such as engines and high-pressure compressors, is expected to produce significant synergies with TGE’s fuel gas supply system.
