2 Ship to shore connection Nordlandkai Lübeck, Germany First commercially operated ship to shore connection in Germany Pilot project together with paper company StoraEnso (Finland) as part of the New Hansa Project Shoreside connection for three paper ferries (Shoreside: Shipside: Hz ) ships are already equipped for shoreside connection in Finland Siemens installed the matching connection point at the berth and set up the connection to the mediumvoltage system of the Lübeck municipal utility. Siemens modernized the Finnish on-board relay technology and created a modern software solution using programmable SIPROTEC multifunctional relays Page 2 09/2012 GER IC LMV MV

3 SIPLINK the flexible and reliable network coupling for shoreside power supply Page 3 09/2012 GER IC LMV MV

4 Qualified planning, project handling and services for your shoreside power supply We assist you with the planning and implementation of your shoreside power supply system, from the initial idea to the commissioning. We draw up a detailed cost / benefit analysis together with you in order to find the optimal solution for your needs. Our experienced project managers ensure that the project is implemented on schedule and with the right quality. And in any of 150 countries, we can be quickly on the spot with a service team should you need assistance with the start-up or modernization of your shoreside power supply system.

5 SIPLINK Shore to Ship connection All components from one source: Siemens AG Local grid connection 2. Harbour substation 3. Transformer 4. Voltage and frequency adjustment and power flow control (SIPLINK) 5. Cable connection to ship Advantages of SIPLINK Ship to Shore connection: Flexible connection to all kind of board grids independently of voltage or frequency One cable connection (MV) instead of several LV connections Galvanic separation of shore grid to board grid in order to keep the respective protection schemes and avoid galvanic corrosion Page 55 09/2012 GER IC LMV MV

16 Thank you for your attention Onshore Power Supply Mobile:

17 Shore to Ship connection with Siplink Benefits Environmentally Friendly Reduction of emissions, noise and vibrations Saves Money Saving of costs for fuels and lubricants Increase of maintenance intervals (savings due to longer service life) Longer useful life of on-board generators Increases Productivity Opportunity to maintain and repair the generators and secondary diesel engines during laying time on port Increase of maintenance intervals (savings due to longer service life) high availability because of less maintenance no shutdown ( black ship ) during the take-over process Page 17 09/2012 GER IC LMV MV

18 Benefits of static converters No increase of short circuit capacity (shore and offshore) Less maintanence needed in comparison to rotating equipment (high availability) Reactive power compensation is built in (within power limits), power factor cos = 1 is achievable on shore side Synchronization easier and faster No inrush-current when switching on (for 4Q units) Output frequency alternatively 50 Hz or 60 Hz (adjustable) No extensive foundation needed Page 18 09/2012 GER IC LMV MV

19 Basic preconditions for a Medium Voltage Onshore Power Supply System Simple plug-in connection from the shore side with interlocking to prevent the plug-in connection from being opened during operation. Personal safety is guaranteed by a safe interlocking system. Connection is automated, so that people without special training can operate it safely. Mooring personal must be able to make the connection. Automatic start-up of the on-shore power supply released by the ship when the plug-in connection is ready. The ship keeps the command over the shore side power supply. It controls start and stop and synchronisation. Control of different frequencies from the shore side to the ship side (50 60 Hz) for different kinds of ships. Page 19 09/2012 GER IC LMV MV

21 Connection The connection between the on-board network an the on-shore power supply is implemented by an industrial plug-in connection proven for years. This plug-in connection has to be standardised generally in order to ensure the same preconditions for the on-shore connection of the ships in all ports. The system is designed to allow the on-board personnel to take the necessary actions by themselves and WITHOUT interruption of power supply when the load is taken over by the on-shore connection. Start and Shut down step by step Page 21 09/2012 GER IC LMV MV

22 Economic Background Theoretically, one kg of MDO generates about 5, practically 3,5 kwh At an MDO price with a sulphur content < 1% of about 106 ct each kwh generated on board costs about 20 ct According to the present market prices for electrical power, the on shore kwh prices are up to 50 % lower, depending on day/night power The calculation for kwh generated on-board out of MDO also have to consider losses for ancillary components as cooling pumps, fans, fuel heating, fuel pumps, etc. and maintenance for diesels. The use of heavy bunker reduces the output to 2,9 3,1 kwh due to losses for fuel heating Page 22 09/2012 GER IC LMV MV
