duties. The subboards consist of a captain as senior inspector  and  about  10  other  members,  depending  upon the type of ship that is to be inspected. The president of the  INSURV  board  determines  the  procedures  the board, and any regional board or subboards will follow to conduct trials, inspections, and surveys. Ships  are  presented  to  the  INSURV  board  for builders’  trials,  final  contract  trials,  material inspections, and surveys. A ship being inspected or undergoing trials by INSURV is considered to be on detached  duty  until  the  trial  or  inspection  is  completed. INSURV Material Inspection INSURV  material  inspections  are  conducted according to statutory requirements of Congress. Those statutes specify the material inspection of a U.S. Navy ship (1) upon the ship’s return from a foreign station, (2) at least once every 3 years (if practical), (3) when fitness of the ship for further service is in doubt, and (4) when the ship has been declared unfit and stricken from the Naval  Vessel  Register. OPNAVINST 5420.70 describes the organization of an INSURV board, including the regional boards and subboards.  OPNAVINST  4730.5  establishes  the  policy used  to  conduct  an  INSURV  material  inspection  of  each active  ship  4  to  6  months  before  the  ship’s  next scheduled  regular  overhaul.  INSURVINST  4730.8 provides  detailed  guidance  for  the  preparation  and distribution of INSURV reports. The INSURV board and the type commander agree on the time and place for a material inspection. The inspection starts promptly upon arrival of the board, and the ship must be moored to a pier or dock during the inspection  so  that  machinery  may  be  disabled.  INSURV material  inspections  are  not  normally  scheduled  during regular overhaul or tender availabilities, and repair work  during  an  inspection  should  be  kept  to  a minimum. The ship’s personnel should submit a list of work items to the board conducting the inspection. The list should  include  all  known  or  suspected  work  needed  to bring the material condition of the ship to the required standard. The list should include the following work items: .  Departures  from  CNO-approved  characteristics, contract  plans,  or  specifications .  Incomplete  or  unsatisfactory  tests . Alterations desired Outstanding  field  changes  of  ship  alterations Equipment  required  by  approved  plans Partially  complete  installations Safety  hazards Repairs  required Equipment  that  fails  to  meet  performance requirements,  requires  excessive  maintenance, leaks  excessively,  is  obsolete,  is  in  excess  of actual  needs,  or  is  unreliable  in  operation Work  items  outstanding  from  previous  trials  or material  inspections The ship’s personnel should prepare the list of work items according to INSURVINST 4730.5 and deliver a set to the board when they arrive. After the material inspection, the board members may make changes and assign  classification  and  identification  symbols.  They will  then  forward  copies  of  the  corrected  list,  and  any items  they  have  added,  to  the  ship  and  the  type commander. The  INSURV  board  uses  Arabic  numerals  and combinations  of  lowercase  letters  to  identify  work items   as   to   reference   number   within   the   ship’s departments such as (1, 2, 3) and the department or division of the ship having responsibility of the item. They use the following symbols to identify the ship’s department  or  division  having  primary  responsibility for a work item: nv  .  .  .  .  .  .  .  .  . op  .  .  .  .  .  .  .  .  . wp  .  .  .  .  .  .  .  .  . dk  .  .  .  .  .  .  .  .  . mp  .  .  .  .  .  .  .  . br  .  .  .  .  .  .  .  .  . ax  .  .  .  .  .  .  .  .  . el  .  .  .  .  .  .  .  .  . dc  .  .  .  .  .  .  .  .  . sp   .   .   .   .   .   .   .   . rp .  .  .  .  .  .  .  .  . md   .   .   .   .   .   .   .   . hb  .  .  .  .  .  .  .  .  . av  .  .  .  .  .  .  .  .  . navigation  department operations  department weapons   department deck  division  or  department main engines division boilers/reactor division auxiliaries   division electrical division repair  division  (damage  control and hull structure) supply  department repair  department medical and dental departments habitability air  department 4-11
