8.1 MAINTENANCE
GENERAL
The Oil Discharge Monitor and Control System is an assembly of components forming a complete
system. It comprises a mix of pneumatic, electronic and mechanical components. Once a control
system is functioning correctly there is no test, or tests, which can be applied to guarantee
successful operation for a stated period of time.
Random failure of components can occur and such random failures can never be forecast. In
consequence, satisfactory operation, in the way the system was designed to operate, is the only test
to apply. This involves frequent operation of the monitor, especially if the monitor is shut down for
long periods.
A test run, once a month, will ensure that the monitor will work correctly when it is required.
Dirt, corrosion and to a lesser extent wear are the enemies of control. This means that clean
conditions must be maintained in the area of the monitoring equipment.
Pneumatic and hydraulic components require little maintenance.
The various moving parts in the system should be free from friction and in good working order.
Oil should not be applied to pneumatic components.
Connections should be tight. Loose connections do not only waste air but produce unsatisfactory
operation and performance.
One of the greatest problems with pneumatic systems is the maintaining of a supply of clean, dry air
at a constant pressure. Moisture, oil or foreign particles carried into the system from the air supply
will cause problems. Pneumatic valves and controllers operating with clean dry air require virtually
no maintenance.
SAFETY PRECAUTIONS:
MAKE SURE THAT ALL SAFETY REQUIREMENTS AS DESCRIBED IN SECTION 4.1
ARE MET BEFORE ANY WORK IS COMMENCED.
NOTE:
If any work is carried out on the monitor, the following precautions should be taken
before any work is commenced:
Thoroughly clean the outside of all fittings, pipes and components, and surrounding
structure before any work commences.
When pipe lines are disconnected fit dust caps to pipes and unions, mask any
exposed surfaces and make certain that foreign matter cannot enter the system.
If flushing pipes, use a clean inert solvent, from a clean container.
