1 Standardization of Shore connection Systems Thomas Hartmann Dept. MPE, Germanischer Lloyd Head Office Hamburg, Germany December 2006

2 Current Regulations LV-shore power: Current classification societies rules and regulations for shore connections deal with low voltage shore power supply only during repair or maintenance. December 2006 No. 2

3 Current Regulations Personal safety: Personal safety of the shore-side personnel is regulated by domestic regulations of the port country. Personal safety onboard is governed by flag state requirements. December 2006 No. 3

4 Current Regulations System requirements: Shore side requirements concerning power quality, installation and operation are regulated by national law and possibly by special requirements of the power utility company, port authorities and port operators. The requirements for the electrical installation onboard a vessel are defined by the rules and regulations of the relevant classification society. December 2006 No. 4

5 Uncharted Areas Ship and shore side installations are designed according to different standards. Responsibilities and liability issues with regard to personal safety when establishing and operating a shore connection are unclear. The operator of the vessel has no influence on the shore side installation and vice versa. December 2006 No. 5

6 IACS - The International Association of Classification Societies IACS has decided to close this gap for ship installations with a unified requirement by creating a working group UR for shore connections for systems with voltages above 1 kv up to 15 kv. DNV, ABS, BV and GL have delegated experts to this working group. The working group will start under the chair of GL with an initial meeting in the fourth quarter of The time frame for completion is approximately one year. December 2006 No. 6

7 IEC International Electrotechnical Commission In May of 2005 a working group of NSMT (Normungsstelle für Meerstechnik) formed with the goal to present a draft to the technical committee TC18 of IEC. Members of this working group are ship-owners, system and component suppliers, port operators and classification societies. A draft paper (committee draft, CD) is expected by the beginning of next year. December 2006 No. 7

8 ISO International Standard Organization ISO TC8/SC3 conducted a kick-off meeting in September of 2006, creating a working group with the aim to start with the development of a ship-to-shore electrical connections for ocean going vessels. December 2006 No. 8

9 The Scope of Future Standardization On shore installations Interconnection systems On board installations Type and routine tests December 2006 No. 9

10 On shore installations System frequency 50/60 Hz Voltage level 11kV Lightning protection Short circuit limitation to 16kA/ 1 sec Interlocking with grounding switch December 2006 No. 10

11 Interconnection systems Standardization of the Plug and socket Cable Cable handling system Communication cable, plug and socket Communication protocol Interlocking / Staff safety December 2006 No. 11

12 On Board Installations Protection of the ship network Equipment onboard has to be protected by its own protection devices Protection of the ship s installations must be guaranteed Shore connection switchboard Interlocking with grounding switch Main switchboard Shore connection switchboard with protection M December 2006 No. 12

13 Type and Routine tests Type tests Plug & socket Shore connection cable Cable handling device Routine tests Workshop tests Dock trial Commissioning test for each new port of call December 2006 No. 13

14 Challenges December 2006 No. 14

15 Challenges The ship owner: Cable reel belongs to port infrastructure December 2006 No. 15

16 Challenges The ship owner: Cable reel belongs to port infrastructure The port authority: There is no space December 2006 No. 16

17 Challenges The ship owner: Cable reel belongs to the port infrastructure The port authority: There is no space Classification: The protection of the cable reel is shore side December 2006 No. 17

18 Challenges The ship owner: Cable reel belongs to port infrastructure The port authority: There is no space Classification: The protection of the cable reel is shore side Utility company: No HV-plugs in my installations December 2006 No. 18
