PRINCIPLES OF NAVAL ENGINEERING 



DAMAGE CONTROL ORGANIZATION 



In order to ensure damage control training 

 and to provide prompt control of casualties, a 

 damage control organization must be set up and 

 kept active on all ships. 



As previously noted, the engineer officer is 

 responsible for damage control. The damage 

 control assistant (DCA), who is under the engi- 

 neer officer, is responsible for establishing and 

 maintaining an effective damage control organi- 

 zation. Specifically, the DCA is responsible for 

 the prevention and control of damage, the train- 

 ing of ship's personnel in damage control, and 

 the operation, care, and maintenance of certain 

 auxiliary, machinery, piping, and drainage sys- 

 tems not assigned to other departments or divi- 

 sions. 



Although naval ships may be large or small, 

 and although they differ in type, the basic prin- 

 ciples of the damage control organization are 

 more or less standardized. Some organizations 

 are larger and more elaborate than others, but 

 they all function on the same basic principles. 



A standard damage control organization, 

 suitable for large ships but followed by all ships 

 as closely as practicable, includes damage con- 

 trol central and repair stations. Damage control 

 central is integrated with propulsion and elec- 

 trical control in a Central Control Station on 

 new large ships and is a separate Station on 

 older and small ships. Repair parties are as- 

 signed to specifically located repair stations. 

 Repair stations are further subdivided into unit 

 patrols to permit dispersal of personnel and a 

 wide coverage of the assigned areas. 



DAMAGE CONTROL CENTRAL 



The primary purpose of damage control cen- 

 tral is to collect and compare reports from the 

 various repair stations in order to determine 

 the condition of the ship and the corrective action 

 to be taken. The commanding officer is kept 

 posted on the condition of the ship and on im- 

 portant corrective measures taken. The damage 

 control assistant, at his battle station in damage 

 control central, is the nerve center and direct- 

 ing force of the entire damage control organi- 

 zation. He is assisted in damage control central 

 by a stability officer, a casualty board operator, 

 and a damage analyst. In addition, representa- 

 tives of the various divisions of the engineering 

 department are assigned to damage control 

 central. 



In damage control central, repair party re- 

 ports are carefully checked so that immediate 

 action can be taken to isolate damage and to 

 make emergency repairs in the most effective 

 manner. Graphic records of the damage are 

 made on various damage control diagrams and 

 status boards, as the reports are received. For 

 example, reports concerning flooding are mark- 

 ed up, as they come in, on a status board which 

 indicates liquid distribution before damage. With 

 this information, the stability and buoyance of 

 the ship can be estimated and the necessary 

 corrective measures can be determined. 



If damage control central is destroyed or is 

 for other reasons unable to retain control, the 

 repair stations, in designated order, take over 

 these same functions. Provisions are also made 

 for passing the control of each repair station 

 down through the officers, petty officers, and 

 nonrated men, so that no group will ever be 

 without a leader. 



REPAIR PARTIES 



A standard damage control organization on 

 large ships includes the following repair sta- 

 tions: 



Repair 1 (deck or topside repair). 

 Repair 2 (forward repair). 

 Repair 3 (after repair). 

 Repair 4 (amidship repair). 

 Repair 5 (propulsion repair). 

 Repair 6 (ordnance repair). 



On carriers, there are two additional repair 

 stations— Repair 7 (gallery deck and island 

 structure repair) and Repair 8 (electronics re- 

 pair party). Carriers also have special orga- 

 nized teams such as Aviation Fuel Repair, Crash 

 and Salvage, and Ornance Disposal. On small 

 ships, there are usually three repair stations- 

 Repair 2, Repair 3, and Repair 5. 



The organization of repair stations is basic- 

 ally the same on all types of ships; however, 

 more men are available for manning repair 

 stations on large ships than on small ships. The 

 number and the ratings of men assigned to a 

 repair station, as specified in the battle bill, 

 are determined by the location of the station, 

 the portion of the ship assigned to that station, 

 and the total number of men available. 



Each repair party has an officer in charge, 

 who may in some cases be a chief petty officer. 

 The second in charge is usually a chief petty
