Block diagrams represent the main arrangements and inter relationships between either different systems or different modules within one system.
They create a general overview of the entire plant.
Units within a plant, shown in blocks, are connected by cables with their corresponding ship cable numbers voltage and number of cores.
Block references consist of: unit reference number, for instance =A1.0 and relative manufacturer’s diagram number (9-A-0050-00).
Cable reference, as a part of ship diagrams, consists of: the cable’s cores, cable type and the number of Incorporated cords.
Any onboard modifications to electrical equipment should be red-lined on the ship’s drawing for future reference.
