We have an external fire protection network in a marine port that has been served by 2 main electrical-driven fire pumps.
The proposed solution on this project is to utilize two main end-suction-type fire pumps using the seawater as a water supply source.
The seawater is near the seashore at a lower elevation than the fire pump base.
To overcome the low pressure of the Net Positive Suction Head, a vacuum priming pump is installed on the suction line to get enough pressure to prime the fire pumps.
Considering this whole assembly is not listed nor approved, and there is no space for a water storage tank, what feedback might you have about the non-listed solution?
We can't provide an extended platform here with a vertical shaft turbine pump, so I'm at a loss for solutions. Thanks in advance.
