Engine Part-Load Optimization
Upgrade your environmental performance and efficiency
Applying EPL (Engine Power Limitation) can be an effective way of meeting EEXI (Energy Efficiency Design Index for Existing Ships) and CII (Carbon Intensity Indicator) targets.
However, with EPL, the engine is operating outside of its optimal range. This leads to increased fuel consumption and reduced combustion quality. Developing a new performance concept for your engine’s operating range will overcome this, saving fuel and reducing greenhouse gas emissions. Combining our expert knowledge in engine performance tuning and turbocharger matching, we can provide you with a package that will reduce fuel consumption by 3 g/kWh up to 6 g/kWh.
We offer technical services that help you future-proof your assets and reap both environmental and commercial gains. As sustainability standards evolve, our upgrades deliver immediate reductions in fuel consumption, emissions, and operating costs.
Engine part-load optimization
Operating engines at low load, Engine Part Load Optimization (EPLO) enables you to considerably reduce greenhouse gas emissions and cut fuel costs. Furthermore, reliability is improved by reducing carbon deposits and improving the combustion process.

Benefits of different options
We’re with you all the way
We will help you choose the right option. Whether it’s permanent engine derating, waste gate installations or simply re-matching your turbochargers to lower engine loads, we’ll find the best for your engine specification, expected load patterns, and regulatory requirements.
We’ll find the solution that gives you the most competitive payback period while meeting your upcoming CII (Carbon Intensity Indicator) ratings or as a part of your SEEMP (Ship Energy Efficiency Management Plan). We’ll lead you to the correct turnkey partner who will take you through the whole project, from finding the right solution to final engineering, including managing your IMO NOx certification and approval of the final EEXI technical file. We will guide you to ensure you remain efficient and compliant.
