Tier III EGR Prepared Engine Concept Considering the following is important, when planning the newbuilding: 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. < 13 >

Tier III EGR Prepared Engine Concept Option 1 EGR Tier III Design Specification A solution fit for the owner who definitely expects to retrofit with EGR in the future, but who would like to delay the first cost expenses for purchasing sub-components. This solution would include the (parent) engine of a certain vessel series to be tested and certified as a Tier III engine from start, with components subsequently being removed from the (parent and not installed on member) engine(s) and blinding flanges installed appropriately. Option 2 EGR prepared Tier II operation A solution fit for the owner who is not certain yet whether retrofit with EGR for Tier III is going to be relevant in the future. This solution would include making space in the engine room, ensuring tank capacity, ensuring that aux. power demands are considered, central cooling water system layout considered for EGR operation and some minor modifications of the engine, such as preparing specific faces for more weight, arranging turbocharger in some cases at engine rear-end and making room for certain valves. < 14 >
