Digitalization for green shipping

Shipping makes an important contribution to GHG emissions. 95% of goods traded around the world are transported by merchant vessels. These ships, like cruise liners and smaller boats, traverse sensitive international waters where they must meet strict emission regulations.

MAN Energy Solutions is a leader in providing clean solutions for the maritime industry. Our technology portfolio helps owners and operators reduce their carbon footprint and meet strict emission standards, present and future, while at the same time keeping vessels efficient and economical.
We focus on utilizing cleaner fuels for a more sustainable, carbon-free future.

The International Maritime Organization (IMO) has set its target: by 2050, the shipping industry must halve its greenhouse gas emissions compared to 2008. This goal is made tougher by the projected growth of emissions that is driven by the increase in international trade. The maritime energy transition is underway, and standards are increasingly strict. MAN Energy Solutions is dedicated to supporting this transition: reducing the maritime industry’s carbon footprint while growing business.

We believe in the power of clean. Our digital solutions help to reduce pollution and give your equipment a more sustainable profile. We achieve this through savings on fuel oil consumption or reducing the methane slip for example. In this way we help you meet all current and future regulations while reducing their overall environmental impact. 


In existing IMO regulations, the EEDI (energy efficiency design index) and other measures operate with CO2 as the only contributor to greenhouse gas (GHG) emissions.

A other regulations is EEXI (energy efficiency existing ship index), a new IMO regulation (from 2022) that aims to reduce CO2 emissions of existing vessels by setting minimum requirements for technical efficiency. CII (carbon intensity indicator) measures, how efficiently a ship transports goods or passengers and is given in grams of CO2 emitted per cargo-carrying capacity and nautical mile.

However, IMO is considering regulating other GHGs such as methane. Upcoming EU regulations FuelEU Maritime and EU Emission trading system (ETS) are expected to cover methane slip from 2025.

To meet the IMO’s 2050 goals and reduce greenhouse gas emissions in maritime shipping, ship owners and builders need to follow multiple tracks. In terms of fuels, that means changing to alternative fuels like LNG, methanol, LPG, and ethane as well as green fuels like ammonia, synthetic methane and green hydrogen.

Digital solutions

Our digital solutions for two-stroke and four-stroke systems include PMI Adaptive Cylinder Control, a fully automatic system that will constantly help you secure optimal engine tuning, continuous lube oil monitoring, or the MAN EcoLoad advisory tool, which watches the powertrain and provides continuous feedback in order to run your plant at its optimal operating point at all times. The MAN ECO CONTROL portfolio is already helping shipowners reap the benefits of reduced emissions as well as greater economy and efficiency.

The common nominators for our digital solutions are:

  • Efficiency increase
  • Fuel saving
  • Optimization on operation
  • Reducing the methane slip efficient performance

PMI ACCo is a fully automatic system that will constantly help you secure optimal engine tuning regardless of engine load, load range, load changes, and varying fuel calorific values.

PMI ACCo is based on a patented closed loop algorithm. Using values from the engine’s performance trial as reference, the algorithm adjusts the fuel index and exhaust valve operation of each cylinder. PMI ACCo is fully automatic and works in all load ranges to ensure the lowest possible fuel consumption.


MAN EcoTorque is a governor control update developed to improve cylinder liner condition and save fuel.

Instead of governing a steady rpm, the engine speed is allowed to drift within a specified range. This means that short-term external influences will not put excess strain on the engine, and the fuel index will remain steady.
