To operate the pump, connect the hose between the pump discharge
connection on the VOSS and to the cargo tanks or the overboard tank.
Perform the following procedures:
(1) Activate the hydraulic power system.
(2) Open the valve to the cargo tank.
(3) Station a lookout at the cargo tanks or overboard tank. Monitor the discharge
and the tank level gauges.
(4) Operate the pump hydraulic directional control valve in "FORWARD" to pump
from the collection well.
(5) Operate the pump hydraulic valve in "REVERSE" to clear the hoses, pump
and to clear debris blocking the pump intake.
NOTE
When pumping heavy, viscous oils, operate the pump slowly to achieve a steady stream of
oil at the discharge of the hose. Gradually increase the speed of the pump while
maintaining a steady flow of oil and hold at that speed for maximum transfer rate. Speed
adjustment can be made at the Parker flow control and also by throttling the directional
control valve actuator handle.
CAUTION DO NOT DEAD HEAD DISCHARGE LINE
ii)
Connect applicable boom system and rigging.
(1) Connect the selected boom to the transition boom ASTM boom-connector.
iii)
Hydraulic control stand
(1) Position a person at the hydraulic control stand to operate the DIP moving
plane and the pump.
(2) The control stand consists of 2 lever controls on the top flat face of the unit
labeled;
(3)
BELT
(forward - neutral - reverse),
(4)
PUMP
(forward –neutral – reverse),
(5) The tuning knobs in front of the levers control the hydraulic flow to each
component.
