2 Disclaimer TECHNOLOGY CAN BE THE ANSWER TO TECHNICAL ISSUES AND ECONOMICAL ISSUES BUT IT IS NOT THE ANSWER TO POLITICAL ISSUES

3 Agenda Emission overview SO X abatement, NO X abatement, CO2 reduction, LNG, Three birds with one stone

4 Emission abatement, overview NO x - Primary dry methods (engine technologies) - Primary wet methods (water use) - Secondary methods (after treatment) GAS SO x (& PM) - Primary methods (low sulphur fuels) - Secondary methods (after treatment) CO 2 - Ship efficiency - Engine efficiency - System efficiency

5 Scrubbing technologies Scrubbing Wet scrubber Dry Scrubber Open loop Hybrid Closed loop

6 Scrubber working principle (Closed loop) Exhaust Gas Closed loop works with NaOH for the neutralization of SOx. CLOSED LOOP = Zero discharge in enclosed area NaOH unit ph Scrubber ph Fresh water Water Treatment Cooling Process tank Holding tank Seawater Sludge tank

7 SO x reduction Pro s & Con s Method / Solution Advantages Disadvantages Scrubber Installation of an exhaust gas cleaning system LSHFO or MGO Switch over to 1.0 % S fuel or MGO in SECA areas MGO Run full time on MGO Lowest total lifecycle cost Use everywhere Easy operation Works with high % S Flexible Small investment Convenient No change over ROI depends on fuel oil price difference between low sulphur fuel oil and high sulphur fuel oil High operating cost Fuel change over Fuel availability Lube oil TBN management High operating cost LNG Gas/dual fuel engines Flexible Convenient Reduces also other emissions Infrastructure still developing Fuel availability Other Cold ironing (shore power). Only possible in port not a solution for SO x abatement at sea.
