Shore power jv will improve air quality
The Swiss-based power technology group ABB and the Italian shipbuilder Fincantieri are
to collaborate on the construction, marketing and supply of high-voltage shore connection
(HVSC) system that will provide electricity to vessels in port, the so-called cold ironing
system.
Shore-based electrical supplies are seen as a significant step to improving the air quality
around ports as ships will no longer have to run auxiliary engines that operate
refrigeration, lighting and cooling and heating systems while the vessel is docked.
According to the two companies involved a large cruise ship in port for 10 hours can
consume up to 20tonnes reducing the CO
2
emissions by some 60tonnes annually, the
equivalent output of 25 European cars.
Swedish ports, including Gothenburg, Stockholm, Helsingborg and Pitea, have seen CO
2
emissions cut by 6000tonnes a year as a result of using shore based power connections,
according to the Swedish Environmental Research Institute IVL.
"ABB successfully delivered the world’s first shore connection to the port of Gothenburg
in January 2000," said Veli-Matti Reinikkala, head of ABB's Process Automation
division. Giorgio Rizzo, head of Fincantieri’s ship repairs and conversions business unit
added: “We are pleased to have contributed, together with ABB, to this initiative, setting
out to protect the environment, which is also a priority objective for shipowners, our
customers.
The new shore connection systems to be developed by ABB and Fincantieri will meet all
current international standards, and can be installed on ships while under construction,
docked for maintenance or even out at sea.
