MSC.1/Circ.1430 FIXED WATER-BASED FIRE-FIGHTING SYSTEMS FOR RO-RO SPACES AND SPECIAL CATEGORY SPACES

The system is manually activated.

All systems should be divided into sections. Each section should be capable of being isolated by one section control

valve. The section control valves should be located outside the protected space, be readily accessible without en-

tering the protected spaces and their locations should be clearly and permanently indicated. It should be possible

to manually open and close the section control valves either directly on the valve or via a control system routed

outside of the protected spaces. Means should be provided to prevent the operation of the section control valves

by an unauthorized person. Control valve locations should be adequately ventilated to minimize the build-up of

smoke.

The system should be provided with a redundant means of pumping or otherwise supplying a water-based

extinguishing medium to the system. The capacity of the redundant means should be sufficient to compensate for

the loss of any single supply pump or alternative source. Failure of any one component in the power and control

system should not result in a reduction of required pump capacity of deluge systems. However, systems requiring

an external power source need only be supplied by the main power source.

The system should be fitted with a permanent sea inlet and be capable of continuous operation during a fire using

sea water.

Vertically the applicable area of all decks, including hoistable decks or other intermediate decks, between

reasonably gas-tight steel decks (or equivalent materials), should be included for simultaneous coverage. Decks

with ramps are accepted as reasonably gas-tight decks assuming that the ramps are always in their closed posi-

tion at sea and the ramps and the decks which these ramps are part of are reasonably gas-tight.

All release controls for deluge systems, , water pressure on the discharge side of all pump units, and the posi-

tion indication of all section valves should be available and grouped together in a continuously manned con-

trol station or the safety centre, if provided.

The length of a deluge section (along the lanes) should not be less than 20 m and the width of the section should

not be less than 14 m. Further, the sections need not be longer or wider than the distance between reasonably gas-

tight steel bulkheads (or equivalent materials). The maximum size of a section on any single deck should be 48 m

multiplied by the width of cargo space (measured as distance between tight steel divisions). Vertically one section

can cover up to three decks.

The pump should be sized to cover the two largest horizontally adjacent sections for type C systems.

Centrifugal In-Line Vertical pump

High velocity spray nozzle

The high velocity water spray nozzle is intended for use in engineered fire protec-

tion systems to give exposure protection to capital equipment. The water velocity

and droplet size are engineered to provide good exposure protection of capital

equipment where a significant throw is required or when the nozzle is positioned

Manual zone / isolation valve

The valve butterfly is used in all water based applications where there are a de-

mand for isolation, drain or test valves. It is also used as manual zone valves in sea

water systems.

Resilient seated butterfly valve, wafer. To be installed between two raised face

flanges in accordance with DIN PN 16 standard.

The S31 butterfly valve is type approved by all the major classification societies,

such as DnV, LR, GL, ABS, BV, CCS

Medium velocity spray nozzle

The Thermospray medium velocity spray nozzle is designed to produce a solid

cone of evenly distributed water droplets, the majority of which are less than

0.4mm Ø. The water velocity at the nozzle exit lies between 15 and 25 m/sec when

used within the recommended operating pressure range of 1.4 to 3.5 bar. Above

3.5 bar the droplet size decreases reducing the fire plume penetration and

increasing the risk of spray pattern distortion by wind.

The ‘type S’ range of drencher nozzles offers the very latest in design and perfor-

mance, being both highly compact and durable. Drencher nozzles are open sprin-

kler nozzles which are available with different sizes of orifices (K-factors).

Drencher nozzle

Single stage, in-line, centrifugal pumps.

The suction and discharge flanges are identical and they are on the same axis. Both flanges are equipped with pressure gauge tapings.

Single entry, closed impeller is equipped with rear rings to balance thrust and is dynamically balanced.

Motor is connected to the pump by an adaptor and a flange.

Pump starter cabinet

Pump starter cabinet for water and/or foam liquid pumps used for fixed fire sup-

pression systems.

The pump starter cabinets are supplied with either soft starter or direct on-line

starter (DOL), depending on the motor current consumption.

Included in the cabinet is an isolating transformer for 1 fase control voltage sup-

ply.
