High power combined with high efficiency: Our two-stroke engines
MAN B&W ME-C
More compact than others, our ME-C engines with electronic controls serve up a host of advantages. You can look forward to superior performance parameters, fully integrated electronic control as well as the necessary fuel injection pressure and rate shaping at any load. Plus the ME-C engine can be retrofitted for alternative fuels such as methanol, LPG, LNG or ethane.
- Engine speed: rpm to 56 – 167
- Output: 4,350 – 82,440 kW at L1
MAN B&W ME-GI
The ME-GI engine impresses with low operating costs and the highest thermal efficiency on the market. Because of its negligible methane slip, low GHG, and reduced CO2 emissions, it is the most environmentally friendly technology available. By the optional use of fuel oil or LNG, it represents a highly efficient, flexible, propulsion-plant solution.
- Engine speed: rpm to 56 – 167
- Output: 4,350 – 82,440 kW at L1
MAN B&W ME-GIE
The technology of the ME-GIE is based on our successful ME-GI engine. This engine can be operated with ethane as well as LNG – which makes it a good choice and especially lucrative for Ethane carriers. This engine offers very competitive fuel oil and gas consumption, plus operational stability and efficiency due to the diesel principle.
- Engine speed: 62 – 127 rpm
- Output: 8,300 – 29,120 kW at L1
MAN B&W ME-GA
The ME-GA engine is the latest addition to our dual fuel portfolio. Methane is admitted during the compression stroke, which allows for a lower supply pressure compared to other dual fuel engines. This is especially advantageous for vessels with large amounts of boil-off gas, like LNG carriers. The ME-GA engine is Tier III compliant in gas mode, and offers minimal installation and operating costs.
- Engine speed: rpm to 66 – 91
- Output: 10,400 – 16,980 kW at L1
MAN B&W ME-LGIM
Our ME-LGIM is a dual fuel engine which is characterized by its high efficiency. One of the advantages: It runs on methanol – the cost-effective and innovative marine fuel of today and tomorrow. Why? It’s biodegradable and burns clean, it is reasonable to modify storage and infrastructure, and it significantly reduces SOx, NOx, CO2 and particulate matter.
- Engine speed: 79 – 117 rpm
- Output: 8,600 – 16,020 kW at L1
MAN B&W ME-LGIP
Our ME-LGIP is the only dual-fuel engine on the market that lets you switch between HFO, MGO and LPG fuels without any loss of power or efficiency. It also ensures long-term reliability - with very minimal maintenance requirements. The low operational costs as well as the simple retrofit solution are particularly convincing.
- Engine speed: 62 - 167 rpm
- Output: 4,350 – 29,120 kW at L1

ME-GI to Power Ultra-Large Hapag-Lloyd Containerships
MAN Energy Solutions has won an order for 6 × MAN B&W 11G95ME-GI Mk10.5 main engines in connection with the building of 6 × ultra-large, 23,500+-teu container vessels for Hapag-Lloyd, one of the world’s leading liner-shipping companies.
The engines will be built in Korea and will offer the option of operating on LNG or conventional fuel, meeting Tier III emission standards through SCR (Selective Catalytic Reduction). The first engine delivery is scheduled for May 2022. Korean shipyard, Daewoo Shipbuilding & Marine Engineering, will build the vessels with delivery expected from April through December 2023.
In the company’s own press release, Rolf Habben Jansen, CEO of Hapag-Lloyd said: “With the investment in six ultra large container vessels we will not only be able to reduce slot costs and improve our competitiveness on the Europe – Far East trade, but also take a significant step forward in modernizing our fleet. Additionally we will further reduce our environmental impact.”
The newbuildings will be deployed on the Europe – Far East routes as part of THE Alliance and will significantly increase Hapag-Lloyd´s competitiveness in this trade. The engines will operate on LNG, but have sufficient tank capacity to operate alternatively on conventional fuel.
Bjarne Foldager, Senior Vice President and Head of Two-Stroke Business at MAN Energy Solutions, said: “These newbuildings will be fitted with mature ME-GI technology that continues to accumulate references across multiple segments. The engines’ fuel-efficiency and negligible methane-slip tie in perfectly with Hapag-Lloyd’s strategy of sustainability. As we move towards a zero-carbon future, the ME-GI showcases our dual-fuel engine portfolio that is future-proofed to handle whatever alternative fuels come to prominence in the decades ahead.”
The new business follows a series of recent ME-GI sales with 5 × 6G70ME-GI Mk 10.5 dual-fuel engines ordered in October 2020 for 5 × Newcastlemax bulkcarriers for EPS, the Singapore-based shipping company. The previous month, Guangzhou Shipyard International Co., Ltd. (GSI) ordered 2 × 6G60ME-GI Mk 10.5 dual-fuel engines for 2 × LR2 tankers for Hafnia, one of the world’s leading, oil-product tanker owners and operators.
MAN Energy Solutions states that its low-speed, dual-fuel references now exceed 360 units, with the ME-GI recording over 1.5 million operating hours on LNG alone.
The ME-GI engine – the new industrial standard
MAN Energy Solutions successful ME-GI (-Gas Injection) engine has set a new industrial standard for two-stroke propulsion engines aboard – among others – container vessels, bulk carriers, tankers, LNG carriers and car carriers. The ME-GI engine provides ship-owners and operators with a peerless solution within environmentally friendly and high-efficiency, two-stroke technology, without the greenhouse emissions such as methane slip that are characteristic of competing engines.
With the ME-GI engine, two-stroke development has taken a step further by combining the unique properties of multi-fuel combustion and the well-known reliability of MAN Energy Solutions ME-engine. The Diesel principle not only provides the ME-GI engine with high operational stability and efficiency, but also ensures 100% stable and reliable operation during load changes on gas with just normal additions of pilot-oil amounts. Furthermore, the ME-GI operational principles features a seamless change-over between gas operation and diesel operation The ME-GI engine is the most environmentally friendly, technology available within the two-stroke engine segment.
MAN Energy Solutions has also developed an ME-LGI (-Liquid Gas Injection) dual-fuel engine that expands the company’s dual-fuel portfolio, enabling the use of more sustainable fuels such as methanol and liquefied petroleum gas (LPG).
The Maritime Energy Transition
MAN Energy Solutions believes that it is time for what it terms a ‘Maritime Energy Transition’ to find clean, decarbonised solutions for seaborne trade and transportation. Essentially, it is the company’s call to action to reduce emissions and establish natural gases as the fuels of choice in global shipping. It strongly promotes a global ‘turn to gas’, driven by the IMO, and a common approach by the shipping industry and politics to invest in infrastructure development and retrofits.
With a fleet of 234 modern container ships and a total transport capacity of 1.7 million TEU, Hapag-Lloyd is one of the world’s leading liner shipping companies. The company has around 13,200 employees and 388 offices in 129 countries. Hapag-Lloyd has a container capacity of approximately 2.7 million TEU – including one of the largest and most modern fleets of reefer containers. A total of 121 liner services worldwide ensure fast and reliable connections between more than 600 ports on all the continents. Hapag-Lloyd is one of the leading operators in the Transatlantic, Middle East, Latin America and Intra-America trades.
