1 1 Building an LNG driven vessel LNG developments at Meyer Werft Viking Grace 18_09_2013 Berufsbildung

2 2 Meyer Werft Papenburg MEYER WERFT is a company with tradition, which started operations in Papenburg on the Ems in For more than 200 years ships of most different types have been built by the experts working for this family-owned company. In 1975 the yard moved its premises to a location on the periphery of Papenburg. Here, cruise ships were built for the first time

3 3 NEPTUN Werft Neptun Werft a 100% daughter is located near Rostock LNG Feeder Tanker build in 2012 at Neptun

4 4 Alternative Fuels First studies on alternative fuel were done in 2008 Meyer Werft participate on research projects GasPax and BunGas Alternative fuels LNG Temperature -161 C relativ storage Volume HFO 1,0 LNG 1,9 Methanol 2,6 Hydrogen 4,6 Methanol Bio-Fuels Tank Hold Space Type C Hydrogen Temperature -253 C The ratio is even higher with Type C Tanks

5 Virtual Vessel Main Particulars Study on a generic Cruise ship 5 Gross Tonnage: 63,000 GT LOA: 238 m Breadth: 32.2 m Passengers/ Crew: Crew Engines: Dual fuel (2 x 6 MW; 2 x 8 MW) Fuel: 2x1000 m3 LNG/ 800 m3 MGO Class notation: EC0, RPS, SRTP

6 6 General arrangement Vent mast LNG-Tank MGO-Tank GVU s Bunker Station Gas handling room Tank Room

7 7 Storage Tank Type In GasPax it was decided to use a LNG Tank with submerged pump - Low storage pressure - Bunkering without disturbance on gas supply - Handling of huge amount of LNG for propulsion (14 m³/h) - BOG storage capacity Vaporizer LNG Storage Submerged pump

8 8 LNG tank installation Tank rooms underneath accommodation (deck 0 to 2) Minimum distance to hull B/5 (IMO IGF) Access of spaces only via man hole from gas handling room Tank rooms with dry air, no permanent ventilation Tank rooms are protected against overpressure caused by an unlikely leakage of LNG or NG Tank connections only inside tank domes, which penetrate the bulkhead towards the GHR Dome is deigned on the same pressure rating than Tank Pressure relief valves installed according to IGF requirement Gas Handling Room Tank Room Tank Dome

9 9 GHR Schematic Machinery Space Access to gas tight GHR via Air-Locks Air-Lock CH4 GHR Output 5 bar g BOG Compressor Air-Lock Tank pressure BOG Engine CH4 GVU Master Gas Valve Gas M CH4 Liquid LNG Water- Glycol Cycle Tank Safety valve Gas tight duct with gas pipe to GVUs Gas heater LNG Vaporizer Tank Connection LNG Tank 2 bar CH4 vent Tank Hold Space

10 10 Ventilation and vent mast Vent mast LNG All ventilation of rooms with gas equipment (GVUs, GHR) is lead through double walled venting duct Ventilation of gas dangerous spaces is 30 air changes per hour Vent mast outlet 10m above uppermost deck

11 11 Bunkering Logistic Future development of LNG Supply Chain LNG Import Export Terminal LNG Feeder Vessel LNG Intermediate terminal Truck or Bunker Vessel Receiving Vessel Today in most EU countries LNG Import Terminal Truck Receiving Vessel Supply chain at some North Sea area LNG small scale Terminal Receiving Vessel Supply chain with certain number of ships and frequent bunkering. LNG Import - Export Terminal LNG Bunker Vessel Receiving Vessel Supply chain with high Bunker demand

12 Open Bunkering Station Bunkering and Vapour return LNG Basin - Natural Ventilation - Gas monitoring - restricted area - Drip Tray and LNG Basin Drip Tray Water Curtain Small leakages are accumulated in the basin and will vaporize in short time In case of a more serious leak the drip tray will guide the LNG overboard A water curtain will protect the hip hull

13 Bunkering Station LNG bunkering Oil bunkering Control room Air Lock Bunkering station with drip tray and Air Lock Double walled piping lead up to the Tanks Automatic shut off valves Nitrogen connection for purging purposes Protection of ships hull against cold spills Gas detection and fire extinguishing systems Safe areas around bunkering station - Ventilation via Vent Mast - Gas Monitoring - Air Lock -Drip Tray will guide LNG overboard -LNG station in cryogenic Temperature resistant steel

14 Draft of an LNG Bunker Barge Draft of a bunker barge by Meyer Werft. Bunkering by Hose transfer between Barge-Receiver Barge with 5000 m³ LNG Max bunker flow rate 500 m³/h (adapted to the need of a cruise vessel)

15 LNG Feeder Vessel MW has build more than 47 tankers, most of them to transport Ethylene and LPG. In 2012 Meyer has delivered the Coral Energy, a m³ LNG feeder vessel. Propulsion by Wärtsilä DF Motor. BOG to Wärtsila Engine BOG and LNG is used to deliver the energy to the Wärtsilä Motor.

16 Retrofitting of a vessel For ships which operate in ECA Areas Investment is quite high and a perspective of the LNG price development is difficult to get. Scrubbers move the problem. Fixed installation Various LNG supply systems on the market Marine Service GmbH LNG container stack

17 LNG perspective Technology to use LNG on new buildings is developed Energy supply for propulsion is approved New buildings of vessel in ECA zone Retrofitting of vessel in ECA zone is at first New buildings of world wide operating vessels
