4-62. When  the  supplying  ship  cannot furnish   an   analysis   of   the   fuel   oil it   delivers,   you   should   take samples   from   the   tank   being   filled by  what  means? 1. From  gauge  cutout  valves 2 . With  a  dipper  from  the  tank  or through   sample   connections   on the   tank   piping 3. Collect   oil   that   is   leaking   at fuel   oil   connections 4. Stop   pumping,   break   the connection,    and   collect   the sample 4-63. After   all   fuel   oil   tanks   are   full, you   should   clear   delivery   fuel   oil hoses  by  what  means? 1. Allow  the  remaining  fuel  to gravity   feed   back   to   the   tank 2. Disconnect   hoses   very c a r e f u l l y, drain  them  to  a large   drip   pan,   and   then   cap the   hose 3. Have   the   supplying   ship   take   a back   suction   or   blow   back   the oil   with   compressed   air 4. Align   the   fuel   oil   transfer system   and   transfer   the remaining   fuel   to   a   waste   tank 4-64. Which   of   the   following   is   NOT  a typical   step   used   to   discharge   fuel o i l ? 1. Sound  all  tanks  that  will  be used   to   deliver   fuel   oil 2. Line   up   fuel   oil   systems   and check  fuel  oil  pump  operations 3. Ensure  the  OOD  has  draft readings   taken   forward   and   aft before   and   after   fueling 4. Heat   the   oil   to   produce   a viscosity   of   250   SSU 4-65. Liquid   is   shifted   from   one   place   to another   on   the   ship   to   produce which   of   the   following   effects? 1. Fuel   economy 2. Attainable   speed 3. Crew   comfort 4. S t a b i l i ty 4-66. The   free   surface   effect   within   a fuel   oil   service   tank   is   limited   by which   of   the   following   means? 1. Maintain   as   close   as   possible to   95%   fuel   levels   in   fuel   oil system 2. Flood   the   fuel   oil   service tanks   with   seawater 3. Provide   proper   ballasting throughout   the   ship 4. Ballast   all   unused   tanks   and v o i ds 4-67. The   ballasting   system   on   board   a ship   is   used   for   which   of   the following   purposes? 1. To   reduce   instability   in   case of   damage   or   small   store   of f u e l    o il 2. To   flush   out   tanks   and   voids 3. To   move   liquids   to   calibrate inclinometers 4. To  transfer  fuel  from  one service   tank   to   another 4-68. What   is   meant   by   the   term   “free surface   effect”   with   respect   to refueling? 1. The  amount  of  free  movement  a liquid  has  in  a  tank  or  void 2. The   effect   of   oil   being discharged   on   water 3. The   ability   of   water   to d i s s o l v e    f u e l    o il 4. The   emulsification   that   takes place  when  oil  and  water  are mixed 32
