11-19. Which, if any, of the following casualty control phases is concerned primarily with complete repairs of the casualty? 1. Phase 1 2. Phase 2 3. Phase 3 4. None 11-20. Prevention of secondary damage effects to engineering plants is an objective considered  to  be  a/an 1. limited  corrective  action 2. emergency restoration 3. complete   repair 4. split-plant   operation 11-21. What is the primary reason for main- taining a split-plant condition on a ship? 1. To  simplify  damage  control procedures 2. To simplify normal maintenance procedures 3. To minimize the possibility of overall casualty to the engineering plant 4. To minimize mechanical fatigue in each  separate  plant Question 11-22 is to be judged True or False. 11-22. 11-23. A ship's engineering plant which is split into two or more independent systems  will  NOT  provide  insurance against damage to the engineering plant. If  the  ship's  fuel  oil  system  is  in split-plant  operation,  bow  does  the after fuel oil service pump operate? 1. It  takes  suction  from  the  after service  tanks  and  discharge  to  the forward  main  engines 2. It  takes  suction  from  the  after service  tanks  and  discharged  to  the after  main  engines 3. It  takes  suction  from  the  forward service  tanks  and  discharge  to the  after  main  engines 4. It  takes  suction  from  the  forward service  tanks  and  discharge  to  the main forward main engines 11-24. 11-25. 11-26. 11-27. 11-28. Each ship's diesel-electric generator plant can operate independently and carry its own connected load. This type of setup is known as 1. segregation 2. duplication 3. split-plant 4. flexibility   and   adaptability Which of the following is a component of a diesel-electric drive installation and is designed for split-plant operation  only? 1. Cooling system 2. Main  diesel  engines 3. Propulsion   generators 4. Starting  air  compressor Which of the following methods for locking the main shaft of a diesel-electric drive ship can NOT be used  while  the  ship  is  underway? 1. The  energizing  of  the  electrical propulsion circuits 2. The setting up of a jury rig to hold the  main  shaft  stationary 3. The  using  of  brakes  to  hold  the  main shaft   stationary 4. The  using  of  a  jacking  gear specifically  designed  for  that purpose Formulating   engineering   casualty procedures pertinent to a specific type of  propulsion  plant  is  the responsibility of which of the following personnel? 1. Type  commander 2. Squadron   commander 3. Engineer   officer 4. Commanding   officer What is the first consideration to keep in mind in the event of casualty to propulsion   machinery? 1. Immediate  suspension  of  the operation  of  the  damaged  plant 2. Prevention  of  further  damage  to  the plant  and  its  auxiliaries 3. Speedy  restoration  of  the  damaged plant 4. Immediate  isolation  of  cross- connected   plants 69
