Plan before you invest
Engineering & Consulting
The right solution for your engine .
Retrofits, new fuels and power projects are big decisions. Our engineers check your engine or site, compare the options and manage the project for ships, power plants and trains.
The challenge
Big decisions need a clear basis

Many options
Emission reduction, new fuels, efficiency upgrades: there are many ways, and not every one fits.

Every engine is different
Engine type, operating profile and space on board or on site decide what works.

Many parties
Shipyard, class society, engine maker and suppliers all need to work together.
What we do
Three ways we support your project
Use us for one step or for the whole project – from the first idea to a running engine.
Pre-studies
We visit your ship or site, look at your engines and your needs, and send you a report with clear technical and commercial proposals.
2-3 days
site visit
10 working days
to your report
up to 3
proposals


Design and simulation
We select engines and configurations, simulate the result and recommend the products that fit – so you know what to expect before anything is built.

Our experience
More than 15 years of engine projects
Engine conversions
Diesel engines in power plants, ferries and RoRo vessels converted to run on LNG and synthetic natural gas.
Emission reduction
SCR retrofits and exhaust gas recirculation for marine and stationary engines.
Lifetime extension
Overhaul and lifetime extension of locomotive engines.
Control upgrades
Safety and control systems of engines upgraded with modern electronics.
How we work
From first talk to finished project
1 · Talk
You tell us about your engine, your site and your goal.
2 · Visit
We look at everything on site – usually in two days.
3 · Proposals
You get a report with up to three proposals.
4 · Realise
Our group companies or partners carry out the project.
Questions we hear
Your questions, answered
What is a pre-study?
A first, separate step: we visit your ship or site and send you a report with up to three technical and commercial proposals within ten working days.
Do I have to order a product after a pre study?
No. After the pre-study you decide whether and how you want to continue.
Which industries do you work for?
Ships, power plants and trains – wherever combustion engines run.
Who carries out the project?
Depending on the project, our operating group companies AES Maritime Projects GmbH, AES Power Projects GmbH or AES Mobile Power LLC.
