  • Why Marine Frequency Converter
  • There are a growing number of luxury cruise liners and fast car carrying vessels calling at international ports and naval vessels berthing at foreign locations.  Many of the port and harbour operators are now offering vessels the opportunity to “plug into”the local city power supply grid on the dockside so the vessel can turn off its engines while at port. Here there is the problem, many countries have their own local power distribution grid voltages, the American continent has a frequency of 60Hz and most of the other countries of the world have a power distribution frequency of 50Hz.
  • When a vessel berths in a port the propulsion engines are turned off but would normally continue to run its diesel engine driven generators to power all of the on board auxiliaries such as air conditioning, heating, lighting, battery charging, communications center water pumps and other utility services. The auxiliary power diesel generators produce noise; vibrations; exhaust smoke; air pollution; toxic gases; and CO2 emissions, as well as consume vast amounts of unpleasant smelling diesel fuel. They incur costly maintenance and the inevitable need for replacement parts as necessary for all internal combustion engines.
  • BWPS shore frequency converters offer a solution to this issue. By shutting down the vessel’s engine driven auxiliary power generators and connecting to our shore to ship frequency changers there is no smell, barely any audible noise to disturb passengers or neighbouring vessel on board personnel, no vibration smoke or fumes, no CO2 emissions or costly diesel fuel or oil.
  • These fixed shore power frequency converters are designed for use on the public supply grid networks of 50Hz or 60Hz with 3 phase standard input voltages of 208V, 400V, 415V,460V or 575V. The output voltage and frequency will be according to the needs of the ship with voltages and frequencies similar to the input.
  • BWPS shore power converter can be manufactured in sizes of 60kVA to 4000kVA in an indoors type of enclosure for installation in a substation or power distribution room. We can also supply the shore power converters in an all-weather outdoor enclosure which is able to withstand the harshest environmental condition for installing on the dockside or mooring berth.
  • The shore frequency converters provide a galvanic isolation between city grid power pick up point and the on board vessel power distribution network. The converters will regulate and condition the dockside power and will eliminate spikes, dips and other voltage surges and instability problems often encountered on feeder networks connecting simultaneously to a number of vessels.
