II - LOADING & OIL MEASUR3MEMT PROCEDURE
Preliminary Steps
In loading a tanker, usually two, sometimes possibly only
one, of the large oil tanks will be draYm on. _ Thus there vail
always be at least one tank which will not be involved in a
loading and which may at the time be receiving oil from the field.
Prior to loading, a short test run will be made, during which
oil will 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 amount of stirring up, as
it were, of oil in the tank involved and tends to equalize any
temperature differences. -^t this time new charts will ce placed
on the recording pressure gauge and flow meter,^the instruments
wound and set at the correct time and the pens inked. The
remote throttle control will be tested and any other tests 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 used in this loading,
and water drained from the loading tanks; and before gauges are
taken the proper valves at the tanks will be closed and sealed,
as explained below.
Gauging and Sampling
When all is in readiness to commence loading, oil in the
shipping tanks will be gauged, sampled and tested for temperature
in accordance with the accepted practice, as will the Dilge water
"tank in C8.S0 it contains oil whicti is to 00 run# IiTiin.6dia.t6ly aitsr
loading is completed and the pumps are stopped, the tanks are
again gauged, and tested for temperature.
The various factors upon which computation of the amount of
oil shipped depends are recorded at the time they are determined,
namely the "It.ir-'h" and "low" gauges 5 and the thermome oer, u^ciro
meter and centrifuge tube readings. Reading of the steel gauging
tapes, and of the instruments referred to, is a comparative ^
simple matter, and when the Shaikh's representative is Present to
check the measurement he need only be concerned to see that tne
readings are correct, and correctly recorded. Tne correctness
of these data being assured, correctness of the result is assured.
Computation of the'gross amount of oil withdrawn, determined from
difference in gaugee in conjunction with volumetric tables lor
