LittleInch,
Many thanks for your response.
We are planning to use a float switch or level switch in discharge line of main pump, when water present in that discharge line of main pump, will send signal to a remote operated valve placed at air line of LVRP so that it closes.

Not concluded yet. We are now thinking of using a external vacuum pump for trying the system before doing any modifications on pipes(since modification is a huge rework).
Many thanks GeorgeVerghese
Air vent height is approximately 13.706 m and top most point of suction line from pump level is 8.226 m. Air vent is provided for the tank

Many thanks for your responses.
we normally test all these tanks for its structural strength, hydraulically by filling tanks till top of the vent (alternate tanks covering all tanks boundaries)
Dear ax1e and katmar,
Many thanks for your feed back.
Due to unavoidable circumstances we had to route this pipe as it is. Some critical rooms are arranged below the valve manifold rooms for this pump. Hence pipe had routed in such a way.
Can I use an external priming pump to clear this...
Scenario
In one of the ships, ballast system for the vessel has routed with an inverted U in pump suction line. This is not an avoidable situation due to space constraints and room arrangements in the vessel.
Refer drawing TANK802P-SUCTION LINE.pdf, here this is typical line from one tank, the...
