In loading a tsnker, usually two, sometimes possibly only
one. of the large oil tanks ^ill be drawn on. Thus tliere will
always be at least one tank which will not be involved in a
loading end which may at the time be receiving oil from the field#
Prior to loading, a short test run will be made, during
which oil vail be drawn from one of the tanks and returned to
the same tank via the circulating line. the purpose of this test
is primarily to warm up the pump engines at idling speed, to
examine the piping for any possible leaks, and, to note pump
pressures etc.- generally to ascertain that the plant is in
proper operating condition. It also permits a certain of
itirrinr up , as it were, of oil in the tanlc involved ami tends
to "equalise any temperature differences. -t this timenew
charts will be placed on the recording pressure gauge ^na flow
meter, the instruments wound and set at the correct time and the
inl ed. The remote throttle control will be tested and any
other t ^ts made to satisfy the operator that the entire system
is in order.
During or prior to this test the incoming oil ^stream from
the field will be diverted to a tank not^to be in this
loading, and water drained from the loao ing tanks f
gaugesare taken the proper valves at the tanls will be closed
and sealed, as explained below.
