Damage Control Rapid Plotting Tip 001
NSTM Changes
(Standard Symbology for Damage Control Manual Casualty Reporting and Plotting)

079-B-1.1 MANUAL PLOTTING TECHNIQUES. Damage reports received at DC repair stations are to be recorded, plotted and forwarded to DCC. The overall ship's survivability status is illustrated by the plot maintained in DCC; there, it is imperative that DC repair stations rapidly forward information which affects the status of the ship in any way. Plotting techniques are illustrated below. All damage will be plotted on the DC subdivision plates to summarize the damage in each compartment. Examples of plotting are listed below:

  1. Line Method
    1. Draw a diagonal line from the affected compartment and connect a horizontal line to it.
    2. Write the compartment number along the top of the diagonal line and the compartment noun name under the diagonal line.
    3. Plot along the horizontal line using it as the base of all Circles.
    4. Continue closing in the Circle when updating the same piece of damage (instead of plotting each update separately).
  2. Box Method
    1. Draw a diagonal line from the affected compartment.
    2. Write the compartment number along the top of the diagonal line and the compartment noun name under the diagonal line.
    3. Plot damage in the box.
    4. Connect diagonal to a large box.
  3. Column Method
    1. Draw a diagonal line from the affected compartment.
    2. Draw a horizontal line connected to the diagonal line.
    3. Plot damage along the horizontal line.
