MAN Diesel & Turbo has received an order to install its second-generation exhaust gas recirculation (EGR) system on a 4,500teu container vessel owned by Maersk Line.
The EGR system will be fully integrated with the vessel’s main engine, a two-stroke MAN B&W 6S80ME-C9 type that will be built by Hyundai Heavy Industries’ engine and machinery division.
The company said that the new system enables the meeting of the imminent IMO NOx Tier-III emission levels that are expected to come into force by 1 January 2016.
The EGR unit comprises a cooler, a scrubber, a water mist catcher and a blower unit, and is designed to be fitted on the engine in the same way as a charge-air cooler.
The new vessel is in the C-class series of 22 container vessels ordered by the Maersk Line and is expected to be delivered in early 2013.
The firm said that, for a test period of three years, the engine will be operated partly with IMO NOx Tier III emission levels.
The EGR system ensures full fuel flexibility, ranging from HFO to distillates and natural gas, and reduces NOx by directing part of the exhaust gas back into the engine’s scavenge air.
