Guide for High Voltage Shore Connection GUIDE FOR HIGH VOLTAGE SHORE CONNECTION NOVEMBER American Bureau of Shipping Incorporated by Act of Legislature of the State of New York Copyright ? American Bureau of Shipping ABS Plaza Northchase Drive Houston TX USA CForeword Foreword It is envisaged that the e ?ect of increasingly stricter air emissions legislation implemented through mainly local air quality controls will see an increasing number of vessels installing high voltage shore connection HVSC in the near future Shore power supply facilities have adopted high voltage rather than low voltage by necessity in order to keep the physical size of related electrical equipment such as shore connection cables manageable Inevitably high voltage would otherwise introduce new risks to ship ? s crew and the shipboard installations if necessary safety features were not built into the HVSC system or safe operating procedures were not put in place Accordingly the requirements of this Guide have been developed with the primary focus on the safety of operating crews as well as for the security of the shipboard equipment It should be noted that the requirements in this Guide have been developed in consideration of the joint e ?ort by IEC ISO and IEEE to establish an international standard for Cold Ironing ?? High Voltage Connection Systems which at the time of the issuance of this Guide is under development The applicable edition of the Rules for Building and Classing Steel Vessels is to be used in association with the subject Guide This Guide becomes e ?ective on the ?rst day of the month of publication Users are advised to check periodically on the ABS website www eagle org to verify that this version of this Guide is the most current We welcome your feedback Comments or suggestions can be sent electronically by email to rsd eagle org ii ABS GUIDE FOR HIGH VOLTAGE SHORE CONNECTION CTable of Contents GUIDE FOR HIGH VOLTAGE SHORE CONNECTION CONTENTS Application Objectives Classi ?cation Notation Plans and Data to be Submitted De ?nitions Alternative Arrangements System Design Shore Power Compatibility Capacity Grounding Circuit Protection Short-circuit Level Compatibility Overvoltage Protection Protective Device Coordination Protection of Transformer Load Transfer Failure Recovery Strategy Safety Interlocks HVSC Circuit Breaker Control HVSC Emergency Shutdown Harmonics Monitoring and Alarms Equipment Design General Protection Against Moisture and Condensation Air Clearance Creepage Distance Shore Connection Switchboard Onboard Receiving Switchboard Cable Management System Shore Connection Plugs and Receptacle Transformer HV Cables ABS GUIDE FOR HIGH VOLTAGE SHORE CONNECTION iii C Installations Equipment Locations Voltage Segregation HV Cable Installation Storage Maintenance Plan Operation Manual Tests HV Switchboard HV Transformer HV Cable Reel Slip Ring Cable Test After Installation TABLE- TABLE Air Clearance AC Withstand Test FIGURE FIGURE FIGURE FIGURE FIGURE Example for Ungrounded LV Ship ? s System Example for Grounded HV Ship ? s System where NGR Value is Compatible with the Ship ? s Design Ground Current Range Otherwise Isolation Transformer may be Required Example for Ungrounded Ship ? s System e g Oil
