CM Technologies touts engine optimisation for regulatory compliance

Now that the EU Emissions Trading System (ETS) is fully in force, engine optimisation is an important strategy in controlling emission-related costs. The ETS, introduced in 2024, completed its transition phase at the end of December, meaning that vessels trading between EU ports must now surrender EU Allowances for all of their verified greenhouse gas emissions.

The cost of full ETS compliance has come as a shock to many ship operators. Some estimates indicate that complying with the latest regulations – now that they are in full force – adds about USD 320 for each tonne of very low sulphur fuel oil consumed on intra-EU voyages. The precise cost varies depending on carbon markets and exchange rates, but the quantum can amount to hundreds of dollars. 

CMT highlights a number of issues that owners and operators should investigate and incremental losses in combustion efficiency are amongst the most easily tackled. The company identifies retarded ignition timing, uneven cylinder loading, and injector degradation as key factors that increase fuel consumption but do not necessarily trigger alarms. Yet each tonne of fuel burnt adds to the allowance requirement.

Joint managing director of CMT, David Fuhlbrügge, warned: “Under full ETS exposure, emission costs are clearly visible at voyage level, which means even modest inefficiencies now have a direct financial impact … shipowners and managers are making greater use of performance data, fuel monitoring and combustion analysis to control fuel consumption and manage emissions exposure as carbon pricing becomes embedded in daily operation.”

Meanwhile this year’s extension of the EU ETS system to cover emissions from methane and nitrous oxide makes combustion efficiency even more important, the company added.
