Why is ME-GI selected for a new building?
OIL → GAS
IMO:
Reduction in carbon intensity per transport work must reach 40% by 2030 compared with 2008, with the aim
of reaching 70% by 2050.
Reduction in greenhouse gas emissions from ocean shipping must be at least 50% by 2050 compared with
2008.
This is achieved by focusing on reducing the emission of methane and volatile organic compounds.
China Environmental Regulations:
As of first of July 2018, methane slip from gas engines is restricted on inland waterways in China. The 1.5-
2 g/kWh limit recently enforced shows a trend towards reducing the methane slip from two-stroke engines
instead of NOx emissions. A requirement the Otto-cycle engine may have difficulties fulfilling. The next step
towards protecting the environment could very well be to expand this regulation to cover Chinese waters in
general.
ME-GI Unique Benefits:
Non-premixed combustion, or diesel combustion. Gas is injected and burned directly resulting in high efficiency, lowest consumption in gas
and fuel operation, combustion stability allows engine can react on fast load changes in heavy weather and under high ambient
temperatures.
Future-proof solution with a robust combustion that can burn gas independent of methane number and without methane slip and therefore
without formaldehyde formation. ME-GI will comply with a potential future legislation concerning methane slip and formaldehyde
formation.
Diesel cycle ensures that operation on gas can be maintained during heavy weather and high ambient air temperature independent on the
type of combusted gas. Operation under the mentioned conditions is maintained without any increase of methane slip.

Why is ME-GI selected for a retrofit project?
OIL → GAS
1. Same reasons why it is selected for a new building…plus…
2. Retrofitted ME-GI engine has similar, if not improved, performance in
gas operation compared to fuel oil operation.
3. Fundamental design of the engine is unchanged when compared to
ME engines, meaning that the application potential for the ME-GI engine
applies to the entire MAN two stroke ME engine programme.
4. GI is simply an add-on to the existing engine. In order to convert an
ME engine to an ME-GI engine, both the mechanical and electrical
components for gas operation need to be installed and the software
enabled.
5. Inexpensive (e.g.compared to LNG tank cost)
6. Speed of the vessel is maintained after the retrofit because ME-GI
retrofitted engine keeps power and performance (this is a serious
disadvantage of low pressure Otto cycle two stroke engines)

PVU – Pump Vaporizer Unit
• MAN own Design & Development
• Low cost pump unit
• Compact design: Hydraulic pistons, vaporizer, filters, etc.
• Embedded redundancy (3 hydraulic pistons)
Fernando Marcos – MAN Energy Solutions España April 2019 11High-pressure gas piping location
OIL → GAS
Purpose:
Minimise a potential hesitation the customer may have towards
installing high-pressure gas piping.
Safety study for the ME-GI concept: Analysis of fires and explosions in
engine room. Study Performed by DNV consulting
Feasibility study for the routing of LNG high-pressure pipes on a
14,000-teu containership design, Odense Maritime Technology, 2017
Parameters Analyzed:
Regulations: the solution complies fully with regulations
Production/complexity: the best solution with focus on
production/complexity
Accessibility: the best accessibility
More information: Perception of risk: the lowest perception of risk
