Ready for Tier III EGR retrofit on newbuildings The current IMO Tier III regulation will apply only to vessels keel laid after January 1st 2016, and as a retrofit installation will be rather comprehensive, MAN Diesel & Turbo has primarily investigated two different EGR Tier III solutions for MAN B&W two-stroke diesel engines. SMALL BORE Tier II Standard Tier III prepared Option 2 LARGE BORE

Along EGR Tier III retrofit concept it is further important to consider along planning of new building: ■ Engine room space for EGR sub-systems such as RTU, WTS, SU, NaOH dosing tank, sludge tank ■ Ship central cooling system capacity, e.g. central cooler size, FW and SW pumps designed for future EGR Tier III operation Design cross-check for aux. power demand and switchboard layout of vessel

OPTION 1: EGR Tier III DS (Design Specification) OPTION 2: EGR prepared Tier II DS (Design Specification) A solution fit for owners who definitely expect to retrofit A solution fit for owners who do not know whether a solution in the future, but who would like to postpone retrofit for Tier III is going to be relevant in the future. the first-cost expenses for sub-components. This solution entails that a parent engine of a certain This solution only includes making space in the engine vessel series is tested and certified as a Tier III engine room and ensuring tank capacity along with minor from...
