Large Scale Projects

In recent years the Laboratory of Marine Engineering has been actively involved in research on propulsion system optimisation, with particular emphasis on theoretical and experimental investigations of engine/load dynamics and the interaction between engine and propulsor. This activity involves expertise in thermo-, structural- and hydro-dynamics but also in control theory, electronics as well as hardware and software development.

The Laboratory of Marine Engineering has been actively engaged in the development of cutting edge technologies for marine propulsion systems, mainly through its participation in numerous research and development projects.

The Laboratory cooperates with other organizations and participates in Large Scale Projects, for example:

Large Scale Projects



h-2 logo

The present HERCULES-2 project is the next phase of the R&D programme HERCULES on large enine technologies. The HERCULES-2 is targeting at a fuel flexible large marine engine, optimally adaptive to its operating envrionment.
More details



The HERCULES-C project is the Phase III of the HERCULES Programme. In order to take marine engine technology a step further towards improved sustainability in energy production and total energy economy, an extensive integration of the multitude of the new technologies developed in Phases I and II is required.

More details



The Centre of Excellence in Ship Total Energy-Emissions-Economy was established at the School of Naval Architecture and Marine Engineering of the National Technical University of Athens on 1st February 2010 and it is funded by Lloyd’s Register Foundation (LRF)*. More details





This project refers to the development of a system for emissions reduction suitable for retrofit in marine engines.

The project HERCULES-B is the Phase II of the HERCULES programme, conceived in 2002 as a 7-year strategic R&D Plan, to develop the future generation of optimally efficient and clean marine diesel powerplants. The research objectives in HERCULES-B focus on the drastic reduction of CO2 emissions from maritime transport. More details




The HERCULES I.P. will develop new technologies to drastically reduce gaseous and particulate emissions from marine engines and concurrently increase engine efficiency and reliability, hence reduce specific fuel consumption, CO emissions and engine lifecycle costs. More details




The research objective of the SMOKERMEN project is to achieve smoke emissions reduction in high and medium speed marine diesel engines, during transient loading and at very low loads, by improved air charging of the engine.

More details


Developing engine adaptive control schemes and governor algorithms allowing maximum exploitation of power train capabilities in all ship operating conditions. More details



To establish a set of correlations between performance, emissions, and engine operating parameters, applicable to a wide variety of direct drive marine engines. To develop a control system including the correlations above, able to optimise engine performance, based on standard measurable operating and external parameters, with emissions level as an optimisation constraint.

Advanced Engine Control System:
The NTUA/LME contribution to the ATECS project was to provide transient simulation results for heavy duty diesel engines, especially for parameters which could not be directly measured in the engine testbeds.


More details


Future Unit Injectors:
• To lower PM and NOx emissions from heavy duty diesel engines toward the Euro IV/V emissions directives while maintaining or reducing the fuel consumption, by refining the diesel combustion system based on the highly flexible electronic unit injector (EUI) technology.
• To develop and test two new generations of electronic unit injector system.
