The grid power solution and the frequency converters typically represent the costliest elements on the shore side.Cable reel and connectorsOn the ship side the following will have to be installed:.Frequency and voltage convertors/transformers.On the land side, the high power cold ironing system consists of the following:

Depending on the energy source, it may also contribute positively to the climate driving effects of ship operation, but as an isolated initiative, it is generally not considered to be among the most cost effective climate initiatives. Shore power may potentially eliminate the local noise and air pollution related to ship activity in a port. Still, cold ironing may be regarded as a mature technology that has been in regular use since the 1980s. Consequently, relatively few vessels and ports are capable of making use of shore power, even though the environmental upsides are considerable. This may include upgrading the grid capacity, frequency converters and complex high power connectors. To serve these vessels with shore power, dedicated and relatively costly installations are required, both on land and on board the vessels.

These vessels are capable of making use of normal grid voltage and frequency, and replace the energy from the generators with the shore power with only marginal investments.įor the larger vessels with higher power requirements (100 kW up to 10 to 15 MW) it gets a bit more complicated. Shore power has been used extensively for many years for vessels with moderate power requirements typically less than 50 to 100 kW. Pawanexh Kohli (Own work) Shore power can be installed for all types of vessel and for all ages with need for power in harbour, and has been used for years especially for smaller vessels, but also some larger passenger vessels.įor smaller vessels to draw power from the land based mains supply when docked is not a new phenomenon.
