1 Feasible SOx solutions Wärtsilä s Environmental seminar in Helsinki at June 22 nd, 2010 Vesa Marttinen, Director, Environmental Services Wärtsilä 1 Wärtsilä 30 April 2010 Decreased fuel cost / Vesa Marttinen

2 Introduction This presentation contains examples of SOx compliance solutions and their feasibility for Ship Owners and Operators. The aim is to highlight different alternatives with feasibility of them taking in to account optimized total result of operations including revenue potential, balance of capital and operational expenditure as well as fiscal result of sustainable impact. 2 Wärtsilä 30 April 2010 Decreased Fuel Cost / Vesa Marttinen

8 SOx regulations framework and latest learning's 8 Wärtsilä 30 April 2010 Decreased fuel cost / Vesa Marttinen

9 Where are Sulphur Emission Control Areas (SECA)? IMO SOx Emissions Control Areas (SECAs) are geographically defined areas where ships must limit their SOx emissions. They are defined as of follows >> SECAs Baltic Sea North Sea English Channel USA & Canada proposal to IMO for a SO x and NO x Emission Control Area. 200 miles from coast. Fuel Sulphur: First 1 %, then 0.1 % 2015, all ships. NOx: Tier III (present minus 80 %) 2016, new buildings. IMO adoption 2010(?), entry into force 2012(?) NS BS EC As of Feb Wärtsilä 1/3/2010

10 Learning's from the past SOx regulation will have impact to shipping community. Having said that it can still be compared to various SOLAS and MARPOL regulation amendments during the past years. Learning's from previous statutory regulation amendments: Once regulations are agreed they also come in to force There will be both operational and technical measures to comply with regulations Solutions will have a development boost few years before the date of entry Marine Environment (or safety, or security) will not change over night i.e. common sense is used with vessels specific date of compliance In first days there is understanding on over overall Health, Safety, Security and Environment. (ref. EU regulation for SOx from boilers ) 10 Wärtsilä 1/3/2010

11 11 Wärtsilä 30 April 2010 Decreased fuel cost / Vesa Marttinen How to comply

12 How to comply with SOx regulations - operational it seems now that the operational solutions are: Change from HFO operations to MGO (MDO) operations Proven technology, several Engines and Boilers already comply this way Full time operation is proven operations Switch when entering to SECA might be safety related operational issue. Challenges with MGO future price Challenges with needed amount of delivered to all ports for bunkering SOx emission trading Not established Could be used per vessel (like national NOx regulations) How to implement per owner/operator or per consortium? 12 Wärtsilä 21 January 2010 Cut Fuel Costs/ Mats Lagström

13 SOx compliance Cold Ironing Proven technology Equipments in land: heavy investment from port -> increased port fees Equipments on ship: sensible investment for both ports and ship owners Environmentally friendly only in case electricity is produced with less CO2, less SOx, less NOx, less waste and with lower material footprint compared to other solutions! 13 Wärtsilä 21 January 2010 Cut Fuel Costs/ Mats Lagström

14 SOx Compliance - Scrubber Exhaust Gas Proven technology Moderate investment for ship owners Additional sludge ~10% (no extra fee) Works with freshwater, where NaOH is added to neutralize SOx. ph ph NaOH unit Fresh water Scrubber Water Treatment CLOSED LOOP = Zero water discharge in enclosed area Cooling Process tank Holding tank Seawater Sludge tank 14 Wärtsilä 1/3/2010

21 21 Wärtsilä 22 June 2010 Vesa Marttinen The profit of business from purchase or charter of vessel through operations years to sale or re-delivery is the period to optimize. This includes revenue, cost, and impact to environment. Thus total result of operations.

Small amount of scrubbing water extracted to remove contaminants. Disposal: Never overboard. Storage: Process tank with some buffering capacity permits: Operation of scrubber with waste water treatment plant out of operation. Also vice versa. Effluent. Cleaned bleed-off. Disposal: At open sea discharged overboard. Storage: A holding tank: Offers storage capacity when operating in a zero discharge mode. Permits cleaning of bleed-off anytime, also when scrubber not running. Sludge. Disposal: In port, never overboard. Storage: In ship s sludge tank, possibly in the existing tank with separator and other sludge. SWS = Sea Water Scrubber FWS = Sea Water Scrubber 23 Wärtsilä 1/3/2010

24 SO x Scrubber: operate HFO, meet environmental demand 1. Immediate savings in SO x Emission Control Areas. July 2010 the increasing premium for low-sulphur fuel will impact the need and by 2015 the ROI even less than one year. 2. In EU ports from SOx compliance need to be met. SOx scrubbing is serious alternative. 3. In global operation drastic savings in 2020 are evident. 4. Savings apply to all ships regardless of age. 5. Wärtsilä SOx scrubber is first approved marine scrubber. 24 Wärtsilä 1/3/2010
