Optimal low load operation

More versatile operation while assuring compliance with regulation

The marine industry is constantly looking into methods for reducing costs and environmental impact. During the later years focus on lower ship speeds has increased significantly. There are several reasons for this increased focus, among others the slowdown in global trade and a strong focus on reducing green house gas emissions.

Emissions from marine diesel engines on large oceangoing vessels are regulated in the MARPOL Annex VI regulation developed in the International Maritime Organisation, IMO. In this regulation emissions of NOx are regulated, and a certificate for compliance with the regulation is issued for every engine, based on test bed verification measurements. Changes in engine adjustments may lead to violation of emission regulation compliance if not handled properly.

Under the Green Ship of the Future umbrella, Maersk and MAN Diesel & Turbo has initiated the Dual/Multi MCR Certification project[i], seeking to improve engine low load performance without compromising the emission certification of the engine.
