3 ALTERNATIVES TO REDUCING NOX AND SOX FUEL SWITCH Switch to low sulphur fuel in SECA. CHANGE TO MGO Run full time on Marine Gas Oil (MGO). Flexible Small investment Convenient Small investment High operating cost in SECA Fuel change over procedures Lube oil TBN management Fuel availability? Short term solution High operating cost Future availability? CONVERT TO LNG Convert engines to run on gas (LNG). A solution which also reduces NO x and particulates Investment cost LNG availability USE Exhaust Gas Cleaning Install an exhaust gas cleaning system (scrubber). Works with high S HFO Lowest total lifecycle cost Use everywhere Easy operation ROI depends on fuel oil price difference between low S fuel oil and high S HFO (scrubber) [Presentation name / Author]

6 WÄRTSILÄ SCRUBBERS AND THE ENVIRONMENT Clean air Clean ocean Clean conscience Efficient scrubbing technology, removing both SOx and particulate matter Scrubbing changes SOx back into sulphates, which occur naturally in seawater Our tests show that we often get far below the set equivalent of 3,5%S down to 0,1%S. Thus removing even more sulphur oxides than required by the rules. Better for the environment than MGO, as it saves energy (refinery) and removes some black carbon (PM 2.5 µm) Water treatment units installed on all installations even in Open loop Water treatment will ensure compliance even at tricky conditions e.g. start-up. Water treatment will ensure that harmful heavy metals (from the engine soot) will not be released into the environment 6

WATER TREATMENT IN OPEN LOOP IS IT NECESSARY? Early experience on board Zaandam indicated that advanced open loop scrubbing water treatment was necessary, when problems with sheening arose.

7 WATER TREATMENT IN OPEN LOOP IS IT NECESSARY? Early experience on board Zaandam indicated that advanced open loop scrubbing water treatment was necessary, when problems with sheening arose. Problems with open loop water discharge will most often arise during start-up of the system, when a plume of particles will be going through the pipes. Without correct water treatment this will be discharged into the ocean and possibly lead to rule breaking. Wärtsilä is committed to following both current and future legislation, as well as providing the best and most environmentally sound technology for our customers. Operation Zaandam test unit before water treatment for open loop was installed. Sheening visible [Presentation name / Author]

9 WÄRTSILÄ SCRUBBER SYSTEMS Two types of scrubber units: V-SOx and I-SOx. A full portfolio to fit any vessel.. Open loop scrubber sea water operations Slightly higher power demand than CLS Does not need caustic soda Applications: main alternative for ocean-going ships Closed loop scrubber closed loop operations Independent on seawater alkalinity Zero effluent discharge an option Low power demand Needs caustic soda as a reagent Applications: seas with extremely low alkalinity and for operators looking for continued closed loop operation Hybrid scrubbers open loop / closed loop operations Flexible system More complex system Applications: ships requiring full flexibility of operations [Presentation name / Author]
