Under Sea Vessel Water Supply

 

 

 

 

 

PROBLEM

Providing adequate and continuous flow of fresh water saturated chamber systems and warm water to diving excursion bells.

 

SOLUTION

Develop a water supply system using a high pressure stainless steel high pressure pump to maintain constant pressure and water flow to depths of 1000 feet below sea level.

 

 

SPECIFICATIONS

Pressure .........................65 Kg/cm2 / 63.7 bar / 925
PSI flow .............................40 lpm / 10.5 US gpm
Temperature ...................39°C
Fluid..................................Water/sea water
Duty cycle ........................Continuous
Drive.................................7.5 hp. Electric w/variable pitch pulley regulator and pulsation dampener

 

BENEFITS

  • Portable, compact, lightweight pump.
  • Continuous, dependable flow and pressure.
  • Energy efficient low H.P. operation.
  • Smooth flow - minimum pulsation.

OPERATION

When diving chambers (under sea vessels) are below sea level, it is necessary to keep the water supply pressurized at 10% above external sea water pressure. At 1000 feet, which is the maximum diving depth of the chambers to date, 35 bar is required. A triplex plunger pump, mounted on a barge, can be used to transfer fresh water down to the chamber system. A regulator will maintains 65 Kg/cm2 pressure on the system to provide continuous pressurized fresh water supply to water system of the chambers for showers, drinking and other standard uses.

 

This system can be also used to pump 39°C hot water from the boiler on the barge through a heat radiating system around the individual diving bells. This warm water is also pumped through small veins in the divers wet suits to keep them warm. By using a stainless steel unchromed pump, heated sea water (rather than fresh water) can be used to warm the bells. This is less expensive, because the sea water can be returned to the sea rather than recirculated.

 


These life support chambers are submersed and under pressure for long periods, therefore it is essential that a constant supply of pressurized fresh water be provided. It is also important for the divers at greater depths to be kept warm to aid their mobility and maintain efficiency.
