Engine optimisation

With maritime transport now operating under the 100 per cent phase-in of the EU Emissions Trading System, shipowners are placing greater emphasis on engine optimisation as a means of controlling emissions-related operating costs, according to German engine diagnostics specialist CM Technologies GmbH. Vessels trading between EU ports are now required to surrender EU allowances for the full volume of verified greenhouse-gas emissions, bringing the transition period that began in 2024 to an end. Emissions costs are now an important factor in voyage economics. Industry reports published at the start of 2026 indicate that full ETS compliance now adds about US$320/ton of VLSFO consumed on intra-EU voyages, based on prevailing allowance prices and regulated fuel emission factors.
