The NIDEC ASI dream is to develop new technologies to reinforce freight links and easecargo flow between land and sea. The main shore connection’s concept is to transfer the

ship load to the shore plant and back without any blackout.The automation system is fundamental to the whole process of allowing the ship’s power

requirement, supplied from its main diesel generators, to be switchedto the shore supply and back again.

Shore Connection Technologies

Large container vessels, LNG tankers, ferries and cruise ships require vast quantities ofelectric power (typically 1 to 5 MW and currents of over 300A) to support heating, air

conditioning and necessary auxiliary ship's systems.

Ships and cruise liners generate large volumes of toxic smokestack exhaust when in port tounload and load cargo, container or passengers. Environmental issues are key priority for

the shipping industry and port authorities.By turning off engines and plugging into shore electricity, toxic ship emissions are reduced

to zero at the port.

NIDEC ASI has realized its dream to reduce toxic ship emissions at the port.

Our ship-to-shore solutions will help ships to make use alternative maritime power systemsthat effectively eliminate the production of greenhouse gases while in port, as well as

reducing noise emissions and saving on fuel costs.
