Basic preconditions for a
High Voltage Onshore Power 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.

Economic Background
Theoretically, one kg of MDO generates about 5, practically 3,5 kWh
At an MDO price with a sulphur content < 0,1% of about 65 US ct
each kWh generated on board costs about 13 € 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 – and is not allowed any more in Europe

Connection
The connection between the on-board network and the on-shore power
supply is implemented by an industrial plug-in connection proven for
years.
This plug-in connection should 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
SEEMLESSLY, WITHOUT
interruption of power supply when the load is taken over by the
onshore power system.

Data Communication Shore <-> Ship
Need for standardization:
• Plug and socket
• Voltage
• Communication
• Safety related via 3 pilot wires included in Power cable
• Informative via fiber optic cables
• Is counterpart available and still alive?
• Starting informations and start command from the ship
• Running alarms
• Stop command from the ship and stop informations

”SIPLINK for Shipyards“
Customer:
Country:
Project:
Date:
Flender Werft AG
Germany
Flender Shipyard
2002
Requirements
Ship construction in Germany: Optimal energy flow between the
shipyard and on-board networks.
Solution
Scope of Supply
1 MVA Island-network power supply for
50/60 Hz ship networks
Reverse power supply from the 50/60 Hz
ship generators into the shipyardnetwork 450V; 50 Hz
Exchange of active power between both
networks in case of peak-load
Reactive power compensation & load
tests of the ship-generators
22
September 2009
SIPLINK showed here what highly modern energy management can
do: whether 50 or 60 Hz is used, this innovative technology
regulates the supply of on-board power from the shipyard network
– and simultaneously ensures that the shipyard network can make
any necessary compensation. In the other direction, it feeds energy
freed up from on-board generator testing into the shipyard
network. This enables testing on-board generators with differing
power factors.
Highlights
Intelligent energy flow between the shipyard and on-board
networks

Solution for SIHARBOR: shoreside power supply
Nordlandkai Lübeck, Germany
Customer:
Country:
Project:
Date:
Stadtwerke Lübeck
Germany
SIHARBOR Lübeck
2008
Requirements
As part of the New Hansa Project, the shore Nordlandkai Lübeck had to
be equipped for a shore to ship connection.
The three ferries TransPaper, TransPulp and TransTimber of Swedish
shipping line TransAtlantic were already operable for the connection.
Solution
Siemens installed the matching connection point
at the berth and set up the connection to the mediumvoltage system of the Lübeck municipal utility.
Scope of Supply
Shoreside power connection
for three ferries
Shoreside: 2,5 MVA/6kV@50 Hz
Shipside: 400 kV@50 Hz
Also, Siemens created a modern software solution using programmable
SIPROTEC multifunctional relays at the shore site.
Highlights
The system installed in Lübeck is the first commercially operated shore
to ship connection in Germany. It is a pilot project together with the
paper company StoraEnso.
