Energieversorgung des Bordnetzes im Hafen – Vorbereitung am Beispiel eines 3400 TEU Containerschiffes
Dipl.-Ing. Heinz-Werner Meyer, TKMS Blohm+Voss Nordseewerke GmbH, Emden
Die zukünftige Nutzung der Landstromversorgung (AMP) während der Hafenliegezeit ist insbesondere auch für Containerschiffe eine wichtige Fragestellung. Die Schiffe sind für weltweite Fahrt konzipiert. In Abhängigkeit von den jeweiligen Charterverträgen und den damit verbundenen Fahrtrouten werden im Laufe der Lebenszeit des Schiffes die verschiedensten Häfen rund um den Globus angelaufen.Aufgrund der derzeit nicht vorhersehbaren Weiterentwicklung der Infrastruktur in den Häfen und fehlender weltweiter Standards sind viele Reeder nicht bereit, die Schiffe bereits während der Bauphase mit AMP-Komponenten auszurüsten, sondern nur darauf vorzubereiten. Anhand der bei den Thyssen Krupp Marine Systems (TKMS) gebauten 3400 TEU Containerschiffen wird an zwei Varianten aufgezeigt, wie eine Vorbereitung für den späteren Einbau von elektrischen Komponenten zur Landstromversorgung aussehen kann. Auf Basis des Bordnetzbedarfs im Hafen werden die elektrischen Komponenten ausgelegt und die Integration an Bord des Schiffes aufgezeigt. Die beiden Varianten – fest eingebaute Komponenten bzw. eine 40’ Containerlösung – werden dargestellt und bewertet.
Shore-based power supply for ships – Examplte for Pre-Installation for Container Ship 3400 TEU

The future application of Alternative Marine Power (AMP) from shore during harbour services is a very important issue for container ships. The ships are designed for worldwide operation and depending on the charter or shiping routes different ports around the world will be used during the lifetime of the ship. Due to the unknwown development of infrastructure for ports and missing standards worldwide, in general shipowners are not disposed to install AMP-equipment from the beginning, often they only order pre-installations. On the basis of the 3400 TEU container ships built at Thyssen Krupp Marine Systems (TKMS) two versions for pre-installation of electrical shore connection components are demonstrated. Depending on the demand of electrical power during harbour operation the components
are designed and integrated in the ship. This is shown for both versions :
Fixed installed equipment and a portable 40’container solution :

At the end of October2008, the SAM project team was able to realise the first complete onshore power supply system (OPS) for successfully supplying container ships with electrical energy in Antwerp (Belgium). OPS – On Shore Power Supply, also known under the name, AMP (Alternative Marine Power), is currently being discussed intensively worldwide, not only among circles of experts.It involves the external supplying of ships with electrical energy while they are
docked. This electricity supply makes it possible for the ships, which currently also leave their diesel generators running for the on-board mains supply, to switch these off. The reduction of the harmful emissions (SOx, NOx respirable dust), as well as material wear and
tear and particularly fuel savings are the distinct advantages of the SAM on-shore power
supply system. SAM has already been supplying various ship-side systems (SAMCon) for several years. In practical operation, these in-shore power supply systems are quickly realisable with
voltages of 6,6 kV (or also 11 kV) with plug-in connections. The SAM system offers nondisrupted
switching of the power supply through fully automated synchronisation of the onboard
and land network. The successful lining of both SAM products carried out in Antwerp the land-side system with the ship-side system, therefore closes the entire functional
chain as a complete system. While in several harbours of the North American west coast,
standardised norms have already been put into operation, with the SAM land connection system, a container ship operation with the onventional 60 Hz operating frequency was able to be supplied with 50 Hz from the European land network while it was docked, for the first time.
