Many organizations such as the IMO (the UN International Maritime Organization) and the EU are focusing on overall reductions of marine pollutions through various means. Progress has been made over the last 15 years despite the massive increase in world seaborne trade. However, there remains the multi-pronged problem of harmful emissions while these vessels must necessarily dock in port.
The best – and at the moment the only – player in town to directly address the problem of environmental pollutants from ships at berth is shore power. There are no feasible alternative solutions currently available or even on the horizon, so to comply with growing legislation both here in the U.S. and abroad, or to get ahead of them, shore power is the best solution for ever-increasing environmental concerns.
Because commercial technology hasn't been around for very long, many companies don't have the experience or expertise to make these conversions and provide the most advanced solid-state technology needed to get the best results.
Noyark is the world's leading manufacturer of solid-state marine frequency converters that enables high-performance power units to convert any conventional electrical power to either 60 Hz or 50 Hz power at the dock.

Buying Guides
Where the load type is inductive in nature, such as motors (fans, pumps, etc), solenoids, and relays, it is essential that high inrush current and short-time overload factors are fully considered
With motors (without a soft start facility) typically drawing on start-up current 5 to 7 times the stated rating of the motor.
A static frequency converter (SFC) is NOT a variable frequency drive (VFD).
Calculate the kVA Rating. 3-phase kVA calculation: voltage x amperage x 1.732 / 1,000; 1-phase kVA calculation: voltage x amperage / 1,000.
Determine the Input (primary) and Output (secondary) Voltage. Input voltage is the voltage of the source electricity that needs to be changed, output voltage is the voltage being supplied by the SFC.
Choose the Right Phase Number. 1-phase power is found in homes and small buildings, while 3-phase power is found in larger commercial and industrial settings.
Determine the Input (primary) and Output (secondary) Frequency. Input frequency is the frequency of the source electricity that needs to be changed, output frequency is the frequency being supplied by the SFC. For shore to ship power conversion, it is commonly change from 50hz to 60hz.
Identify the Load Type. Inductive or resistive, direct start or soft start, what is the maximum starting current, etc.
Choose Suitable Protection Degree. IP20, IP44, IP54, Containerized.
Identify Installation Conditions. It is necessary to know: indoor or outdoor installation; installation site altitude and climatic characteristics; ambient temperature.
