Machinery  Repair  Division The  machinery  repair  division  consists  of  the  inside machine shop, the outside machine shop, the boiler shop, and the foundry shop. We will explain each of them in the following paragraphs. INSIDE MACHINE SHOP.—  These  personnel repair or fabricate mechanical parts that require work done on machine shop tools and equipment. They do metal plating and engraving, and they test metals to determine  their  characteristics.  They  also  handle alterations  designated  for  forces  afloat. OUTSIDE MACHINE SHOP.— These  personnel shop test and repair all types of machinery used in naval ships. They also handle alterations designated for forces afloat. BOILER  SHOP.—  These  personnel  shop  test, inspect, and repair boilers of naval ships. FOUNDRY   SHOP.—   These  personnel  pour castings of various metals to produce repair parts and whole items used on the ship. Electrical Repair Division The electrical repair division consists of the electric shop, the gyro shop, the printing shop, and the photo shop. ELECTRIC SHOP.—  These personnel inspect, test, repair, and make adjustments to nearly all electrical equipment,  and  they  also  handle  electrical  alterations designated for forces afloat. Electronics Repair Division The  electronics  repair  division  consists  of  the electronics shop and the calibration shop. ELECTRONICS SHOP.— These  personnel  align and  repair  all  types  of  electronic  equipment,  make  field changes,  and  maintain  an  electronics  publications library. CALIBRATION  SHOP.—  These personnel repair and calibrate most test equipment used on naval ships. SHIP  REPAIR  FACILITIES Most  SRFs  are  located  outside  the  continental United States. They are supervised by naval officers who are assisted by enlisted and U.S. civilian personnel. Other  personnel  are  citizens  of  the  country  where  the SRF is located. An SRF has drydocks and shops that can handle  nearly  all  ship  repair  work.  They  normally handle voyage repairs and overhauls of ships that are based in the area. They do not do new construction. SRF  organization  is  based  on  standard  naval shipyard organization modified for local conditions. Figure 9-1 shows a typical SRF organization. ADMINISTRATION  AND  CONTROL An  SRF  is  under  the  control  of  a  commanding officer,  usually  a  captain.  It  is  part  of  a  fleet  or shore-based  activity  that  exercises  military  command. The   SRF   staff   includes   a   planning   officer,   an administrative  officer,  a  management  engineering officer,  and  sometimes  a  general  manager  for  civilian personnel who acts only as an advisor. An SRF provides logistic support including drydock overhaul, repair, alteration, and conversion of naval ships and service craft, and ships and craft of other U.S. government departments as assigned. They also perform voyage repairs  and  related  work  and  they  install  and  maintain shore-based  electronic  equipment  and  provide  technical assistance  to  assigned  naval  activities. PLANNING AND ESTIMATING (P&E) The planning department is under the direction of the  planning  officer  who  is  a  senior  engineering  duty (ED)  officer.  It  does  all  planning,  estimating,  designing, scheduling,  and  reporting.  It  is  patterned  after  those  in naval shipyards but on a smaller scale. The P&E superintendents’ billets are tilled by ED officers. They include a senior P&E superintendent, assistant  superintendents  for  material  and  finance,  and other related military and civilian positions depending on the amount of work done at the SRF. The planning department is the first point of contact for a customer ship. 9-6
