CHAPTER 9 SHIP AVAILABILITIES, REPAIR ACTIVITIES, AND SHIP TRIALS When you have read and understood this chapter, you should be able to answer the  following  learning  objectives: l Describe the kinds of ship availabilities. intermediate  maintenance  activities  (SIMAs),  ship repair  facilities  (SRFs),  naval  shipyards,  and  private l Explain the difference between alterations and shipyards. repairs. . Identif y and explain the purpose of the kinds of .  Identify  and  explain  the  functions  of  inter- ship  trials. mediate  maintenance  activities  (IMAs),  shore A  ship’s  effectiveness  depends  on  its  ability  to function well; therefore, we have to keep it in prime condition. That means that the ship’s crew routinely handles  normal  maintenance  and  repairs  and  that  we have a dependable system for those the ship’s crew cannot  handle. This  chapter  deals  mostly  with  those  jobs  the  ship’s crew cannot handle and which are done by the following repair activities, which we will explain in greater detail in this chapter: l An intermediate maintenance activity (IMA) is a repair  ship  (AR),  destroyer  tender  (AD),  or  submarine tender (AS). .   A   shore   intermediate   maintenance   activity (SIMA)  is  based  on  land  and  offers  services  similar  to those of an IMA. l A ship repair facility (SRF) is similar to a naval shipyard but on a smaller scale and is usually based outside  the  continental  United  States. . A shipyard is any full service naval shipyard or a civilian shipyard contracted for Navy work. The  engineering  department  officers  and  enlisted supervisors have an interest in nearly all of the work a repair activity does on their ship. You should be familiar with the procedures that will ensure the best job within the   funds   available.   This   chapter   will   help   you understand  what  happens  when  a  repair  activity  works on your ship. TYPES OF AVAILABILITIES An  availability  is  the  period  of  time  a  ship  is assigned to undergo maintenance or repair by a repair activity. Only the authority granting the availability can change  the  allotted  period  of  time.  However,  a  repair activity  may  recommend  a  completion  date  to  the granting  authority  or  request  an  extension  of  time  to complete work already underway. There are several types of ship availabilities that we will define in the next paragraphs.  For  example,  restricted  and  technical availabilities differ in whether the ship is or is not ready to carry out its mission. l l A restricted availability (RA) is used to complete specific items of work in a shipyard or SRF; the ship is NOT available to perform its mission during that time. A technical availability (TA) is used to complete specific items of work in a shipyard or SRF; the ship IS available to perform its mission during that time. Other types of availabilities identify the type of work to be done and where it will be done. . A regular overhaul (ROH) availability is used to complete general repairs and alterations in a naval shipyard  or  other  shore-based  repair  activity.  The 9-1
