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: 10kV/6kV@50Hz, Shipside: 400V@50 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 medium-

voltage 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


SIPLINK – the flexible and reliable network coupling for shoreside power supply


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.


SIPLINK – Shore to Ship connection

All components from one source: Siemens AG

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

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


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


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.

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


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
