Onshore Power Supply


Bookmark and Share

Because there is no international standard in place, only a few vessels are currently equipped to use OPS technology and the systems in use differ in their technical solutions, voltages, power and frequency. Ships with OPS equipment onboard cannot therefore be connected to all the terminals equipped with OPS.

To solve this problem, the international standardization organizations (IEC/ISO/IEEE) are preparing new standards for high-voltage shoreside power supply. The new standard is expected in early 2011 and will deal with the parameters mentioned.

Frequency as a challenging issue

One challenge is that different parts of the world use different electrical frequencies. In addition, onboard frequencies also differ. Once the IEC/ISO/IEEE standards have been finalized, all parties will be in a position to use mutually compatible technologies. This will expedite developments owing to lower costs and increased compatibility between shoreside installations and onboard equipment.
