Cold Ironing Power System design requires unique components to supply shore power to ships for “cold ironing” operation. Currently; development of new standards are in progress and operating procedures are being written to maximize electrical safety, standardization of the process and interchangeability from one location to another. This paper describes the power system design including power system protection scheme which should enhance the electrical safety by design. Power system grounding, equipment grounding, and touch potential that can impact personnel safety are described. A very basic outline of the operating procedures and training needed for the operators to maximize electrical safety during cold ironing operation are also included in the paper. In addition, paper provides the current status of the Draft IEC/ISO/IEEE Standards 80005-1 and 80005-2.
