MAJESTIC UNITY

CONVERSION OF H.F.O. SYSTEM TO M.D.O. SYSTEM

Installation of new fuel changeover solenoid valves for M.A.N. generators.
The pneumatic valves are electrically controlled from a locally placed control panel.
All pipes fitted were schedule 80.
All pipes leading to and from the control valves were of the non-return type.
Air supply for the solenoid valves was piped directly from the generator emergency air start bottle.
Solenoid valve supply for indication and control box power supply were taken from the generator 24volt system.
M.D.O. priming pump 440volt supply was taken from the emergency switchboard and routed via emergency stops

In-line relief valve incorporated into new generator fuel system	H.F.O supply & return lines to generator flat

New M.D.O drop line with new constant pressure valve fitted into original piping

New M.D.O. priming pump	New N.F.O inlet filters & supply meter

All new H.F.O. piping was followed with steam tracing & subsequently lagged.

All major pipelines fitted with pressure guages and thermometers where required	Both H.F.O supply and return meters fitted to system
