1 Where to use Fire Water Hydrants

A Fire Water Hydrant is a manually operated fire protection equipment, intended to be used by trainedfire fighting personnel.Hydrants are simple to use, and can be put quickly in operation.Firewater hydrants are installed along walkways and escape routes in the deck areas of the platform,such that any area can be reached from 2 different hydrants.Hydrants can be made with AFFF or other suitable foam liquid when protecting an area containingflammeable liquids. The foam can be supplied from the platform foam ring main, or from a local foamtank integrated in the hydrant unit. Firewater Hydrants give a flow of 300 450 lpm, depending on thechoice of nozzle, and is a thereby a powerful extinguishing device. The firewater hydrant is used forextinguishing fires directly, but also to provide a heat shield for the personnel to access and closevalves or leakages causing the fire.

2 Technical Description

The standard FPE Fire Water Hydrant consists of the following main components:

* Cabinet* Firewater inlet piping* Firewater isolation valve* Hydrant valves* Hydrant hoses* Nozzles

FPE manufactures Fire Water Hydrants with waterways in titanium, bronze alloys and stainless steel.

The hydrant is made as a unit where the hydrant valves, hoses and nozzles are safely installed in afreeze protected stainless steel cabinet. The two hydrant valves are connected to a common manifold,which has a flanged inlet connection. The hydrant valves are fitted with standard hose couplings. Thecabinets have sufficient space for four off collapsible fire hoses with couplings, and two off fire hydrantnozzles.

A Fire Water Hydrant is used by uncoiling the full length of hose, if needed two off lengths of hose thatwill be connected.The hose is then connected to the hydrant valve in the one end and to one of the nozzles in the otherend. It is important to be aware of the following in order to operate the hydrant safely: Make sure that

the hose lays on the deck in smooth curves. Make sure that the nozzle is closed, and open the hydrantvalve slowly, to fill up the hose with water.When the hose is pressurized, start aiming water in the direction of the fire.

Fire Water Hydrants may be equipped with on- off hydrant valves or pressure regulating hydrant valves,which can be preset to give a desired nozzle pressure.If the inlet pressure to the hydrant exceeds 9 bar, FPE recommends to use a pressure regulatinghydrant valve, in order to be able to control the nozzle safely.

3 Flow capacity for Fire Water Hydrants

FPE Fire Water Hydrants are designed to give a maximum water flow. The flow capacity of the hydrantwith different types of nozzles can be found in the table below.

Fire Water Hydrant

(without pressure regulating hydrant valve)

Configuration 1x15m hose w/ 95GPM nozzle 1x15m hose w/ 125GPM nozzle

Inlet pressure, [Barg] Flow:

6 283 340

7 306 367

8 327 392

9 347 416

10 366 439

Flows are given in Liter per Minute [Lpm]

For hydrants supplied with a pressure regulating hydrant valve, this should be set to give a suitablenozzle pressure.

All nozzles are designed to give their peak performance at a pressure of 100 PSI, approx 7 Barg. Thenozzle pressure should ideally not exceed this level, because of the reaction forces from the nozzle.The flow figures for a Fire Water Hydrant with pressure regulating hydrant valves will therefore beapproximately as the flow rating of the nozzle. If it should be desirable to operate the hydrants at lowerflows and nozzle pressures, this can easily be adjusted.

FPE recommends that the nozzle pressure should not be below 50 PSI, approx 3.5 Barg.
