ENGINEMAN  1  &  C the basis of what the inspection discloses, it may be necessary to recommend repairs, alterations, changes,  or  developments  which  will  ensure  the material readiness of the ship to carry out the mis- sion for which it was designed. In addition, the material  inspection  determines  whether  or  not proper procedures are being carried out in the care and  operation  of  machinery  and  equipment. Administrative procedures and material records which are inspected include maintenance records and routine tests, and inspections. Preparation  for  the Material Inspection At an appropriate time prior to the date of the inspection, the chief inspector will furnish the ship  with  advance  instructions.  These  instructions will  include: The   requirements   prescribed   for   material readiness are as follows: 1. Established routines for the conduct of in- spections   and   tests,   schedule   for   preventive maintenance,  and  a  system  which  will  ensure timely and effective repairs. 1. List of machinery and major equipment to be opened for inspection. The limit that a unit of machinery or equipment should be opened is that  which  is  necessary  to  reveal  known  or probable  defects.  The  units  selected  to  be opened should be representative and, in case of a multiple-shaft ship, should not disable more than one-half of the propulsion units. Proper con- sideration must be given to the ship’s operational schedule  and  safety. 2.  Adequate  material  maintenance  records, kept in accordance with current directives that give the history and detailed description of the condi- tion of the machinery and the equipment. 2. List of equipment to be operated. Auxiliary machinery such as the anchor windlass, winches, and steering gear are normally placed on this list. 3.  Planned  and  effective  utilization  of  the ship’s facilities for preservation, maintenance, and repair. 3. Copies of the condition sheets. These are checkoff  lists  which  are  used  for  the  material inspection. 4. Correct allocation of necessary work to the following categories: (a) the ship’s force, (b) the tenders  and  repair  ships,  and  (c)  the  naval shipyards or other shore repair activity. 4.  Any  additional  instructions  considered necessary by the type commander or other higher authority. The scope of the material inspection is similar to that of the inspection made by the Board of Inspection  and  Survey.  (These  inspections  are discussed later in this chapter.) These inspections should  be  thorough  and  searching,  and  cover,  in detail, maintenance and repair rather than general appearance. The   distinction   between   ad- ministrative  inspections  and  material  inspections should be readily recognized, and there should be as little duplication as possible. Examination of the  material  maintenance  records  and  reports should be made to determine the material condi- tion of machinery and equipment. General ad- ministrative   methods,   general   appearance, cleanliness of compartments, and cleanliness of machinery are not part of this inspection, except in  cases  where  they  have  a  direct  bearing  on material condition. Each  department  must  prepare  work  lists showing the items of work to be accomplished and the  recommended  means  for  accomplishment (shipyard, tender or repair ship, or ship’s force during an overhaul or upkeep period.) The items are arranged in the recommended order of impor- tance and numbered. A list of the outstanding alterations is also made up for the inspection. Work lists usually consist of 5 by 8 cards, with one repair or alteration item on each card. The work  list  should  include  all  maintenance  and repair items, because if material deficiencies are found during the inspection they will be checked against the work list. If the item does not appear on the work list, a discrepancy in maintaining the required records will be noted by the inspector. The composition of the inspecting party for the material inspection is similar to that of the administrative.  inspection  party. CONDITION  SHEETS.—Condition  sheets are made up in accordance with the needs of the different material groups. The engineering depart- ment is primarily concerned with the machinery, the electrical, the damage control, and the hull 2-46
