3 Who is Fjord Line? Norwegian owned company - management of the ships from Denmark. All ships flying Danish Flag & Registered in DIS.

4 - Present lines and ships MS Bergensfjord Year around route Passangers (840) Cars/Cargo (350/0, 150/45) Build 1993 HSC Fjordcat Summer route only Passangers (676) Cars/busses (220/4) Build 1998 Rute West Bergen/Stavanger-Hirtshals 3 weekly roundtrips Bergen/Hirtshals 4 weekly roundtrips Stavanger/Hirtshals Rute South Kristiansand Hirtshals Up to 3 daily round trips May - September only

5 March 2010 Fjord Line ordered 2 identical Ro-Pax Vessels Which will be serving two routes between Norway & Denmark Delivery spring & autumn 2013 from Bergen Group Fosen Vessel was prepared for LNG with DF engine etc. June 2012 decided to go for pure LNG solution as fuel.

6 Vessel Data (Design/Installations) New build 87 Delivery: April 2013 In traffic: May 2013 New build 88 Delivery: August 2013 In traffic: September 2013 Yard: Bergen Group Fosen Yard Length: 170 meter Width: 27,5 meter Cruise speed: 21.5 knots Max speed 24.5 knots Max pax: Crew cabins 67 (100 beds) Passengers cabins 306 (1188 beds) Cargo capacity: 3900 tons Cargo Lane meters: Up to 1650 meter (4,5 meter free height) Cars/trailers capacity: 600/115 Conference capacity: approx. 350 persons (488 m2) Shopping area: 600 m2 Engines: 4 Engines output: kw app. 30,000 HP Powered by LNG LNG capacity 2 x 300 m3

7 The LNG Solution onboard 2 x LNG 6 bunkers line to TCS & LNGTanks One cold flare mast with pipes from all gas compartments

8 The LNG Solution onboard - 4 x Rolls-Royce B35:40V12PG engines each rated at 5400 kw - 2 x 300 m3 LNG tank inkl. TCS with max. Pressure of 8 barg (30 days) - 2x Gas valve unit compartments - Rolls-Royce ACON Gas monitoring safety system inerface with SAM Plantinium IACMS

9 Gas fuelled propulsion system Tank room with PBU vaporiser, fuel vaporiser and fuel heater normal operation Fuel heater - vaporisation and heating Fuel Vaporiser PBU Vaporiser Fuel heater GRU Fuel Vaporiser PBU Vaporiser

10 Safety onboard Gas from Gas Regulating Unit (GRU) Prechamber gas Gas dangerous area Main gas supply 1. Double walled Gas Supply pipes from LNG tank to combustion chamber 2. Gas detection in outer pipe system (ventilated 30 times per hour) 3. Block and bleed valves stops all gas supply to the engine, if unexpected stop occurs 4. Gas detection system above the engine according to class requirement.

13 Gas fuel bunkering process Liquefied Natural Gas (LNG) is bunkered by pressure from : 1) land based stations or 2) tanker trucks or 3) coastal tankers or 4) future bunker barges Top filling (spray) line & Bottom filling line Bunker station LNG fuel tank

14 LNG bunkring Permanent Risavika Stavanger

18 Gas Consumption: Pure Gas vs. Dual Fuel 18 Specific Fuel Energy Consumption (kj/kwh) SFC DF engine SFC SI lean burn gas engine Engine Load (%) 100 % load - 7,7 % diff. 50 % load - 16,1 % diff.

19 Core Technology Status Gas Engines, compliant with the current IMO II legislation and IMO III from 2016 Rolls-Royce Engine nett GHG (CO2-CH4 slip) reduction is 22% NOx curves NOx (g/kwh) IMO Tier I (2000) IMO Tier II (2011) B35:40 gas IMO Tier III Rated Engine Speed

20 Better engine room environment Clean engine - crankcase after running hrs on LNG More or less no oil vapours No oil spill/sludge Reduced fire risk

27 Summary Marine Gas engines represents well proven technology. LNG is available increased demand will ensure even better distribution network. Dual fuel engines are the choice when enough LNG cannot be carried to complete the voyage. Where the application allows single fuel marine gas engines: More efficient Less expensive in terms of operating and life cycle cost. Lower emissions, Less complex engine supporting systems. Green profile for the ship owner marketing tool. Lower lube comsumption Lesser or no sludge No oil spil during bunker operation Better working environment for engine crew

28 Fjord Line have received financiel support From EU / Ten-T programme Norwegian Nox Fund
