Container power for container ships: as part of a pilot project, a compact power plant running on liquefied natural gas (LNG) supplies shore-side power even to gigantic, 20,000-TEU vessels

Supplying environmentally friendly power to ships during lay times means fewer harmful emissions in port: this is made possible by a newly developed compact generator that has recently been successfully tested on several 20,000 TEU mega-vessels in Hamburg. The mobile power plant is the size of two 40-foot containers and has a tank filled with liquefied natural gas (LNG). This is a natural gas that has been condensed into a liquid by cooling it to approximately minus 160 degrees Celsius.
The compact generator allows ships to switch off the auxiliary diesel supplies they would normally use to generate electricity during lay times. By drawing power from a mobile generator, harmful pollutants like sulphur dioxide, particulate matter and nitrous oxides are considerably reduced and in some cases even eliminated entirely. The “Becker LNG PowerPAC” was developed by Becker Marine Systems, a Hamburg-based technology supplier.
Following completion of the pilot project, which also involved Hapag-Lloyd and the Hamburger Hafen und Logistik AG (HHLA), the power generator could be implemented in numerous other ports. As yet, the potential of LNG for container shipping is far from exhausted: the substance is predicted to have a great future, in particular as bunker fuel for ships.
