valve and opening the stripping main suction cutout valve (relock the manifold valves). 3. Align the piping from the flood and drain man- ifold  to  the  suction  side  of  the  motor-driven  stripping pumps. 4. Align the motor-driven stripping pump dis- charge  piping  to  pump  into  the  contaminated  settling tank or overboard (with the commanding officer’s per- mission). 5.  Open  required  valve  on  the  single-valved  strip- ping manifold. 6. Start the stripping pumps, and strip each tank one at a time until they are completely empty of all ballast water. 7. Secure the flood and drain manifold and close all valves in the single-valved manifold. By use of the motor-driven stripping system, strip all storage tanks that are to be used in both the receiving operation and the internal transfer operation before receiving  JP-5  aboard.  Verify  all  stripping  operations were successful by sounding the tanks, using water-in- dicating paste. Strip  the  slack  (partially  filled)  service  tanks,  us- ing the hand-operated stripping system. NOTE Ships planning to replenish in port MUST deballast  tanks  before  entering  port. Internal  Transfer Top off all slack service tanks. This will allow a longer  settling  time  for  the  JP-5  being  received.  Con- solidate  the  fuel  load  by  transferring  from  slack  stor- age tanks to completely fill as many tanks as possible. This will reduce the number of tanks to be filled and will  minimize  the  number  of  tanks  affected  if  con- taminated  fuel  is  received. CAUTION When fuel is to be transferred internally or received aboard, the overflow tank for every nest of tanks scheduled to receive fuel must be empty before fuel can be introduced into any tank in that nest. Filling  Sequence Before receiving fuel, the JP-5 below decks su- pervisor  should  have  soundings  or  readings  taken  on all storage and service tanks. A statement showing the amount  and  location  of  all  JP-5  on  board  must  be submitted to the V-4 division officer. It is the respon- sibility of the JP-5 below decks supervisor to know how much fuel is on board, where it is located, how much more can be received, the order in which the tanks  should  be  filled,  and  the  approximate  duration of  the  receiving  operation. To determine the amount of JP-5 to be received, add the total capacity in gallons of each empty storage tank plus the amount required to top off any slack tanks. In determining the filling sequence, allow for a minimum of six tanks (three port and three starboard) on the line at all times. Knowing in advance the order in  which  the  tanks  will  be  filled  will  assist  in  the assignment of sounding teams, manifold operators, and  the  overboard  discharge  observers. Three  factors  are  involved  in  determining  the  du- ration of the receiving operation: the amount to be received (previously determined), the maximum re- ceiving rate of the particular ship, and the normal pumping  rate  of  the  tanker.  The  latter  two  can  be gained through experience and information recorded in the receiving log. But, if this is the first experience with the tanker, the pumping rate can be obtained in advance via radio messages to the tanker. Personnel  Preparations A fueling watch list should be posted at least 24 hours before the refueling operation. In addition to the posted list, each man should be informed of his station and instructed in his duties. During the instruction period, emphasis should be placed on safety, emer- gency  breakaway  procedures,  and  other  possible  haz- ards.  Assign  only  experienced  and  capable  personnel to actually perform the duties. Limit the number of trainees,  especially  at  the  filling  connections.  Too many people at this station are not helpful and may confuse the operation by getting in the way. When- ever possible, rotate experienced personnel to other stations.  This  not  only  will  give  the  individual  the broadest  training  possible,  but  also  will  produce  a more flexible division. As a rule, fueling stations should be manned 1 hour  before  fueling  time.  The  refueling  stations  to  be manned  and  their  locations  are  as  follows: 1.  Below  decks  office.  This  is  where  the  below decks  supervisor  will  coordinate  the  onload  of  fuel. 4-63
