a U.S. civil service employee or a local employee, as are their  lower-level  supervisors.  These  shop  masters  are assistant repair superintendents who supervise all work done in their specialties whether in their shops or on the ships. (NOTE: Some fleet activities have a ship repair department, or SRD, rather than a repair division.) The  assistant  superintendent  who  is  responsible  for hull  work  is  also  responsible  for  drydocking.  The  actual drydocking is supervised by a docking officer who is usually   an   ED   officer   with   special   docking qualifications.  Navy Regulations and the Naval Ships’ Technical Manual require that the docking officer take responsibility for the ship when it starts to cross the sill of the drydock, and give responsibility back to the ship’s CO when the ship clears the sill on the drydock on its way out. We will discuss docking in more detail later in the  chapter. Shop Division This division maintains and supports the equipment and structures in the shops. It is headed by a shop superintendent, usually a LCDR, who may be an ED officer   or   line   officer.   The   division   also   handles production  methods,  safety,  stores,  and  housekeeping. In  a  naval  shipyard,  this  division  would  also  be responsible for industrial supervision, but the repair division  handles  it  in  an  SRF.  The  shop  superintendent usually   has   a   junior   officer   as   assistant   shop superintendent  and  safety  officer. Ship Superintendent The repair superintendent also supervises a group of officers called ship superintendents. They are junior ED  officers  or  line  officers  whose  duties  parallel  those of  the  ship  superintendents  in  IMAs,  SIMAs,  and  naval shipyards. When a ship is assigned an availability, the repair  superintendent  assigns  a  ship  superintendent  for that ship. The ship superintendent gets copies of all work requests that are sent to the ship and the shops to help them keep track of all work in progress on the assigned ship. The ship superintendent is liaison between the ship and the repair superintendent. He directs all work on the ship and coordinates all work done in the shops. He coordinates all tests, changes in work requests, ordering of material, and sign-offs of work orders for his assigned ship. NAVAL  SHIPYARDS Naval shipyards are under the control of the Naval Sea  Systems  Command  (NAVSEASYSCOM).  Each ship in the active fleet is assigned a home yard and a planning yard. The home yard is the naval shipyard at which a ship usually gets its regular overhaul. CNO assigns  the  home  yard  based  upon  the  geographic assignment   of   the   ship   and   NAVSEASYSCOM recommendations. NAVSEASYSCOM assigns the planning yard One naval shipyard or other activity is assigned as a planning yard for each ship type. The planning yard provides design services and keeps up-to-date tiles of working drawings and selected records and data. The planning yard usually does the design work for the class of ship assigned and provides the required drawings to each of the other shipyards working on ships of the class. The planning yard also may handle central procurement of material. Shipyard management is responsible for all phases of naval shipyard activity. The line of authority and control  passes  from  the  shipyard  commander  through the  heads  of  departments,  divisions,  and  offices  to  the administrative units. See the  U.S. Navy Regulations  and Navy Department directives for additional information on naval shipyard management and organization. Figure 9-2  shows  the  organization  of  a  typical  U.S.  naval shipyard. A ship’s engineer officer will be most concerned with the planning and production departments. The planning department prepares plans and orders material, and  the  production  department  is  made  up  of  the  shops that do the actual repair work on the ship. We’ll discuss both in the next paragraphs. PLANNING  DEPARTMENT Before a ship begins an overhaul, the shipyard’s planning department usually receives a copy of the ship’s  worklist  and  the  amount  of  funding,  both approved by the TYCOM. The planning department uses that information to develop preliminary estimates of the work that can be done with the available funds. It sends them to the production department where the production control branch of the repair division uses the estimates  to  schedule  the  workload.  Next,  the  planning department  prepares  requisitions  for  material  requiring long  lead  time,  and  issues  a  preliminary  work  booklet for  repairs.  Figure  9-3  shows  the  organization  of  a typical  planning  department. When a ship is to be overhauled, the shipyard tries to send representatives to inspect the ship before it reaches the shipyard. They check plans against actual conditions  and  make  any  adjustments  before  the  ship 9-8
