4-16 Fuel Transfers -Cont'd.
a.
Direct Feed from Associated Pipeline to the Contaminated Fuel Module
When fuel coming from the associated pipeline is off specification, normally during the passage of the interface as
determined by the sampling procedures outlined in para. 42. 4a, feed is cut to the contaminated fuel module as follows:
1.
Prior to the anticipated arrival of the interface, open valves V2CF and VSCF.
2.
When the sample results indicate action is required, promptly open valve V 1CF.
3.
Promptly dose the valves V1JM (HD or HM) to the switching manifold as may be in service at the time.
4.
Feed is cutback to the switching manifold when and as described in para. 14-16.5b.
5.
At an appropriate time, usually after a transfer to the contaminated fuel tanks is completed, the contents of off
specification fuel can be pumped out of the contaminated fuel tanks as follows:
a)
Open valvesV3CF and V4CF to pump out tank T1CF or valves V6CF and V7CF to pump out tank T2CF.
b)
Connect the 3inch coupling to the tanker-truck.
c)
Open V8CF.
d)
Start the pump PICF and pull suction from the tank while opening V1OCF.
e)
When pump out is complete, dose V 10CF and immediately shut down P1 CF.
f)
Close valves V3CF and V4CF or V6CF and V7CF as the case may be.
b.
Cut Feed to the Switching Manifold
Prior to this step, the valving in the route to the appropriate storage tank must be opened in accordance with the
appropriate procedure described in para. 4-16.d or e.
1.
Open valve VIHJ and promptly dose VICF. The switching manifold will now be pressurized and fuel will be
flowing in the route selected.
2.
Close valves V2CF and VSCF.
c.
Feed Switching Manifold from the Tanker-Truck Receipt Manifold
As with feed from the associated pipeline in 416. 5b, the valving in the route to the appropriate storage tank must be
opened in accordance with the applicable procedure described in para. 16. 5Sd or e.
