Hapag-Lloyd Boosts Fuel Efficiency with Engine Optimization Technology
Leading container line Hapag-Lloyd is implementing advanced engine optimization technology developed by Accelleron and HD Hyundai Marine Solution (HMS) to significantly reduce fuel consumption and emissions across its fleet. Initial trials on two vessels have demonstrated fuel savings of over 5%, with plans for expansion to eight additional ships.
Engine Part-Load Optimization Delivers Significant Savings
Accelleron and HMS have successfully completed Engine Part Load Optimization (EPLO) projects on the 14,000 TEU Basle Express and Essen Express. These projects involved modifying main engine tunings and turbocharger components to optimize performance at lower engine loads . Sea trials and subsequent operations have shown fuel savings exceeding 10g/kWh, equivalent to a 5% reduction in overall consumption within specific load ranges , , .
How EPLO Works
EPLO ensures vessels operating at reduced engine speeds – often to comply with energy efficiency regulations and reduce carbon costs – run as efficiently as possible. The optimization process includes engine tuning for part-load operation, turbocharger adjustments, and the integration of cut-out systems . This allows vessels to maintain required propulsion power while maximizing fuel savings, even after previous retrofits like hull and propeller enhancements designed to reduce power needs .
Rapid Implementation and Fleet Expansion
The optimization of the Basle Express and Essen Express was completed efficiently, with commissioning finalized just four weeks after the initial orders were placed , , . Based on these positive results, Hapag-Lloyd plans to extend the EPLO solution to the remaining eight vessels in its Dortmund Express-class fleet .
Addressing Regulatory Pressures and Industry Trends
The adoption of EPLO is driven by increasing pressure to improve vessel competitiveness and comply with evolving regulatory frameworks, such as FuelEU Maritime and the EU Emissions Trading System, which incentivize emissions reductions . Accelleron and HMS report having secured contracts for over 100 vessels globally, demonstrating the growing demand for this scalable retrofit solution .
Dr. Christoph Thiem, Hapag-Lloyd Director Fleet Innovation & Projects, stated that enhancing vessel efficiency is a “key pillar of our energy efficiency and decarbonization strategy.”
