3 Color Line in Zahlen Gründung: 1959 Zentrale: Oslo, Norwegen Daten: 6 Schiffe + 4 Routen + 7 Häfen Mitarbeiter: ca Passagiere: 4,5 Millionen/Jahr Umsatz: 543 Millionen 2013 >

4 2012 Gesamt: 10 Mio Euro Investitionen in Landstrom >

5 IMO SO x Emission Control Areas Geographically defined SO x Emission Control Areas (SECA) where ships must limit their emissions.* The SECA is expected to expand outside Europe. North Sea Baltic Sea English Channel * As of February 2006 >

6 Marine Sulphur Limits Sulphur limit (%) World 67% 78% 71% 97% 86% EU in ports 0.1 ECA California Review of the 0.5% S global limit to be performed in In case readiness is not deemed to be sufficient by 2020, the introduction of the limit will be postponed to Fuel type Exhaust gas cleaning Particulate Matter (PM) Not regulated = both HFO and distillate are permitted. Permitted alternative under Regulation 4 to achieve any regulated limit. No limit values.

14 Alternatives to Reducing SOx FUEL SWITCH Switch to low sulphur fuel in SECA. Flexible Small investment High operating cost in SECA Fuel change over procedures Lube oil TBN management Fuel availability? CHANGE TO MGO Run full time on Marine Gas Oil (MGO). Convenient No change over 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 SCRUBBERS 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

15 Wärtsilä exhaust gas cleaning system The sea water is sprayed into the scrubber at several levels Scrubbing water system The scrubbing water is collected at two levels of the scrubber and led to the residence tank Sea water is pumped from the sea chest to the scrubber Exhaust gases flow through the scrubber from bottom to top

16 Wärtsilä Open Loop Scrubber Engine Exhaust Gas Laser Gas Analyser Possible plume control Scrubbed Exhaust Gas Sea water Sea water from scrubber Sludge Control data HMI Control Cabinet Scrubber unit Optional Return pump Water treatment Water Monitoring De-aeration vessel Water monitoring Sludge Tank Wash water discharge Scrubber Supply pump In port reaction water pump

17 Wärtsilä Open Loop Scrubber

18 Wärtsila Inline Scrubber Color Line SuperSpeed 2 Sailing twice a day from Norway to Denmark with a service speed of 26 knots 4 x 9,45MW Wärtsilä engines running at HFO with average 2,3% S. Retrofit: space limitations in funnel Wärtsilä Inline Scrubber installation March 2014 at FaYard in Denmark 18 Wärtsilä This document is the property of Wärtsilä Corporation and shall not be copied or reproduced without the consent of the owner.

19 Wärtsilä Abgaswäscher verfügbare Systeme Seewasser Abgaswäscher offenes System Verwendet salzhaltiges Seewasser Höhere Pumpenleistung nötig als beim Frischwassersystem Keine Verwendung von Chemikalien (z.b. NaOH - Natriumhydroxid) Anwendungen: Seegehende Schiffe in offenen Gewässern mit mittlerer bis hoher Alkalinität Frischwasser Abgaswäscher geschlossenes System Unabhängig vom umgebenden Medium (Salz-/Süsswasser) Geringe Wassermengen ermöglichen Zwischenspeicherung (Zero Discharge) Geringe Pumpenleistung erforderlich Einsatz von NaOH (Natronlauge) zur Neutralisation Anwendungen: Bereiche mit geringer Alkalinität, geschlossene Gewässer / Süsswasser, Forderungen nach zeitlich begrenzter Autonomie (zero discharge) Hybrid Abgaswäscher offenes oder geschlossenes System Flexibe Lösung mit beiden Systemen Komplexes System zur Erfüllung variabler Anforderungen Nachrüstbar für offene Seewassersysteme Anwendungen: Schiffe mit hohen Anforderungen an flexible Einsatzmöglichkeiten (ggf. wechselnde Einsatzbereiche)

20 Seawater Composition Engine Exhaust Chemistry: S + O 2 SO 2 (~95%) SO / 2 O 2 SO 3 (~5%) Scrubber Chemistry: SO 2 + H 2 O H 2 SO 3 (Sulphurous Acid) SO 3 + H 2 O H 2 SO 4 (Sulphuric Acid) Scrubber Reactions: CaCO 3 + H 2 SO 3 CaSO 3 + H 2 O + CO 2 2CaSO 3 + O 2 2CaSO 4 (Calciumsulphate) From: Wikipedia, Chemische Zusammensetzung der Meeressalze, 2013 An analogy that has been used is if all the sulphur in the world's oceans were to be removed, it would form a layer around the earth about 1.7M thick. All the sulphur in all the known oil reserves would add only another 10 micron (0,01mm) to this layer. From 2009 EGCSA - Exhaust Gas Cleaning Systems Association (
