Marine And Shipyards

A yard supplies dozens of vessels that were built for different grids. Conversion equipment on the dock removes the argument about whose frequency is correct.

Pain Points

  • Vessels in for fit out or repair need 60 Hz while the yard runs at 50 Hz
  • Yard supply must present an IT system with neutral insulation to the vessel switchboard
  • 400 Hz is needed for some naval and offshore equipment
  • Running gensets in a dry dock is unacceptable for fire and fume reasons

What The Specification Has To Deliver

  • Selectable output frequency
  • IT system output
  • Stable voltage during heavy stepped load
  • Robust enclosure in a wet dock environment

FAQ

Questions Buyers Ask

Can one converter serve vessels on both 50 Hz and 60 Hz?

Yes. Output frequency is selectable at 50 Hz, 60 Hz or 400 Hz with 0.01 accuracy.

Does the output present an IT system?

Yes. The output system is IT with neutral insulation, which is what most vessel switchboards expect.
