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.

No. 2
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.

No. 3
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.

No. 4
“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.

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 2006.
The time frame for completion is approximately one
year.

•
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.
