MAN Diesel & Turbo announced that it will deliver world’s first IMO certified two-stroke engine with Tier III NOx control and Exhaust Gas Recirculation Systems. While there are already IMO Tier III-compliant vessels with EGR systems in service, the Suezmax newbuildings will be the first vessels with keel-laying after 1 January, 2016 to be officially certified as complying with Tier III emission restrictions within existing North American NOx Emission Control Areas (NECAs) and the United States Caribbean Sea NECA.

If a diesel engine installed on board a vessel has to be replaced by a non-identical diesel engine, the replacement engine has to comply with IMO Tier III emission regulations for installations after the 1 January 2016. The market is only starting to respond to this demand, and it may be difficult to find a suitable replacement engine complying with Tier III. DNV GL explains in this technical news how to handle this issue.
