Who is Fjord Line? Norwegian owned company - management of the ships from Denmark. All ships flying Danish Flag & Registered in DIS.
- Present lines and ships MS Bergensfjord Year around route Passangers (840) Cars/Cargo (350/0, 150/45) Build 1993 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 HSC Fjordcat Summer route only Passangers (676) Cars/busses (220/4) Build 1998
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.

YearTonnes of NOx and and The Environmental Agreement (NOx Fund in Norway when trading domestic). The Environmental Agreement on NOx was signed on the 14th of December 2010 by 15 business organisations and the Ministry of the Environment. The agreement is an extension of the the Environmental Agreement on NOx for the period The Environmental Agreement - and the Participant Agreement - constitutes the framework for the efforts of the Business Sector’s NOx Fund. Through this Agreement, the Business Organisations shall facilitate concrete reductions of the nitrogen oxide gases harmful to the environment. Undertakings which sign the Agreement will be exempt from paying NOx tax in return for their commitment to the obligations laid down by the Business Sector’s NOx Fund whose primary task is to provide funding for NOx reducing measures. The Agreements are important contributions to meet Norway’s commitments in the Gothenburg Protocol for 2010 and the future NOx commitments Norway will receive in In addition, the work ensures improved calculations on NOx emissions. The Environmental Agreement In total, the Business organisations shall facilitate emission reductions stipulated in the Agreement to 16,000 tonnes of NOx, as well as maintain the effect of the obtained emission reductions for the entire period. The Agreement has for this period both yearly and two-year goals to fulfil. Norwegian domestic regulations

Gas fuel bunkering process Top filling (spray) line & Bottom filling line LNG fuel tank Bunker station Liquefied Natural Gas (LNG) is bunkered by pressure from : land based stations or tanker trucks or coastal tankers or future bunker barges
Safety onboard Gas from Gas Regulating Unit (GRU) 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. Prechamber gas Main gas supply Gas dangerous area
Clean engine - crankcase after… running hrs on LNG More or less no oil vapours No oil spill/sludge Reduced fire risk Better engine room environment

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
