. Supervise the maintenance of the damage control log  that  contains  violations  of  the  prescribed  material condition of readiness. Log entries must include the name and rate of the person requesting the authority to violate  a  prescribed  condition.  They  must  also  include the time of the violation, the type of fittings involved, the estimated duration of the violation, and the actual time the material condition of readiness is restored. . Determine the status of fuel and ballast tanks that were empty or filled during the watch and enter the information,   including   the   number   of   the   tanks concerned, in the rough log. . Make hourly reports to the OOD concerning the watertight integrity of the ship. .  Make  sure  the  ship’s  draft  is  recorded  (taken,  if in   port,   otherwise   computed)   daily   during   the 0400-0800 watch. Do it before entering or leaving port and  before  and  after  replenishment  (fueling, provisioning, or rearming). l Make sure damage control patrols sound all voids and  cofferdams  once  each  watch  and  report  results. .  Notify  the  OOD,  DCA,  and  weapons  (deck) department officer when the fire alarm board indicates that the temperature of any magazine is above 105°°F. . Maintain custody of the master key for repair party  lockers  and  make  sure  it  is  issued  only  to authorized personnel. . Make sure material condition Yoke is set before sunset.  Normally,  at  the  end  of  the  working  day (approximately 1700) the damage control watch officer asks the OOD to have all divisions check the setting of material condition Yoke and makes reports to the DCC. The damage control watch officer initiates the necessary follow-up  action  to  ensure  compliance  by  divisions failing to make reports. The  damage  control  watch  officer  reports  directly to  the  OOD  on  matters  affecting  watertight  integrity, stability, trim, or other conditions that adversely affect the  safety  of  the  ship.  He  reports  to  the  DCA  for technical  control  and  matters  affecting  the administration  of  his  watch. The Damage Control Watch Figure 1-7 shows the damage control condition IV watch  organization.  Enlisted  personnel  for  the  repair division  normally  man  the  damage  control  patrol (sounding and security) watches. The sounding and security watch reports to the damage control watch officer. Chief and first class petty officers of the repair division in some ships augment the watch personnel assigned the duties of the damage control watch officer. The Engineer Officer of the Watch The EOOW is the officer on watch in charge of the main propulsion plant and of the associated auxiliaries. On some smaller ships, the EOOW may be a senior petty officer. He is primarily responsible for the safe and  efficient  performance  of  the  engineering department  watches  (except  damage  control)  associated with the equipment in his charge. The engineer officer determines  if  an  officer  or  petty  officer  of  the engineering  department  is  qualified.  If  so,  the  engineer officer  assigns  him  to  the  watch.  The  engineer  officer or, in his absence, the MPA is authorized to direct the EOOW  concerning  the  duties  of  the  watch  when  such action is considered necessary. The EOOW has the following  responsibilities: . Make frequent inspections of the engineering department machinery (boilers, engines, generators, evaporators, and auxiliaries) to make sure they are operated according to current instructions. Make sure required logs are properly kept; machinery and controls are properly manned; all applicable inspections and tests are  being  performed;  and  all  applicable  safety precautions  are  being  observed. . Frequently monitor IC circuits in use to make sure required circuits are properly manned, circuit discipline is being maintained, and correct message procedures  and  terminology  are  being  used.
