IntroductionConventional fixed gas fire extinguishing systerns have a iatd |Hlataage; ddayed startof fire extinguishing due to complete evacuatbn of crew from tE gEiE run-In order to solve this problem, ll\4O focused attenti]fr on rder rdst fE fig i€q|stems asa method of suppressing and extinguishing fire at its ealy sfagB d, €rurgh time forevacuation and safety of crew.In contrast with usual spdnkler system, this nraler rist spn l|as a sitifcant suffocatingeffect produced by spraying extremely fine mist r der llich Gart prorire eftctive conholof oil fires.For ships keel-laid on and after 1st July 2002, the instaldbn cJ ttE! sysEns b required inthose areas with a high fire risk, in machinery spaces irdudirg i*enrd combustion mainengines, auxiliary engines, burners for boibrs, incinefab(s, kE{t gas genefators and CO.purifiers.

The main fire extinguishing system must be ready for use when a fire ts Deyond thecontrol of this system.Ship's crews are required to be familiar wiih operation of the fire extinguishjng systernfor entire machjnery spaces as well as this system.

Outline of Hyper-Lp systemThis system mainly consists of a exclusive centrifugal pump, automatic control valves,mist nozzles and control panels.The Hyper-LP water pump dmws fresh water from the hull tank and discharges throughselected distribution valves to the spray nozzles, which spray mist partjctes for at least20 minutes.

7. Rout ine check and maintenanceA) Everyday

1. Make sure sufficient water is available in the fresh water tank.2 l\4ake sure power is prcperry suppried to the operation paners and the starier of

the Hyper-Lp waier pump.3. Press "Lamp & Buzzer Test, button to make sure all the indicating lumps lighted

and the buzzer sound.4. Make sure the drain valve and the test valve are closed.5. Keep the area around the Hyper_Lp water pump clear of any obstructtons whjch

Interfere with the operation.6. lf Hyper-LP Water pump Starter is equipped with following switches, check them

as follows.. Change-over SW: Check that it js turned to. Coil Heating SW: Turn jt on jf condensation

B) Every 6 months1. Conduct functional test of the system as follows.

a. Unplug power supply line inside of the starter panel for Hyper-Lp water pumpso that it won,t accidentally start running.

b. Remove restriction cover on ,,System Stad,,button.c. Press "System Start,'button on operation panels and make sure the following.'Suctjon valve and branch valve of Hyper-Lp water pump are openeo, and"Suctjon Valve Open" lump on main control panel is lighted.

. "Run" lump for Hyper_Lp water pump on majn control panel is lighted.. "Mist Discharge', lumps on main control panel and on alarm ,onnol- p"n",are Iighted.

. Alarms jn protected area and on alarm monjtor panel sound.Reinstate the system after making sure all these.

2. l\,4ake a test run of Hyper-Lp water pump, discharge water from the test ttne.Drain water after conducting the test.

*) Test Runa. Turn off the power of the main control panel, then open manual valve and

automatic valve on the suctjon line manually.b. Open the manual valve for the test line manually.c. Activate the Hyper_Lp water pump from the starter panel manually to check

the operation.NOTE:

. ldling and closed operatjon of the Hyper_Lp water pump are stricflyprohibited. Make sure that water js suppJied when activating the Hyper_Lpwater purnp.

ts expected.

. The electric ball valve provided by Kashiwa automatically closes whenpower is fed.Therefore, DO NOT tum m lhe power for the majn control paner wnenconducting operation test for ItE pump.

Restore the system to the oritird conditjon after conducting test run.Drain water from the test line.

C)Annual ly1. Check and clean the strainer of ttE Flyper-Lp water pump suction line.2. Conduct the test acmrding to'OrS€.d test method,' in final drawings. XX lf onboard test has been corducbd by the shipyard, ',Onboard Test Method',

might not be inserted in final drawirgs- lf that is the case, please contacr us.D) Mist Nozzles

Check and clean the strainers insirre the mist nozzles used for discharging water toprotected areas after operation.Also, cleaning the strainers inside all mist nozzles js recommended durinomaintenance at a dockyard.
