13-3.2.1 General Electrical System Safety. The maintenance and operation safety
aspects of the high-voltage distribution system, substations, vaults, and low-voltage
cables in duct lines is covered in previous sections.
13-3.2.2 Specific Shore-to-Ship Electrical System Safety. This section covers
connection of portable power cables to shore electrical outlet assemblies and ship
electrical buses. Connection is a divided responsibility as shown in Table 13-1. Follow
the Standard Operating Procedure (SOP) established by the Shore ES. An example of
the SOP for a typical vault substation arrangement to ensure that energizing the ship is
accomplished safely is shown in Figure 13-15.
