20-JUL-20064. DESIGN BASIS
Fire protection system consists of fire water main distribution system, water and foam protection system, portable fire extinguishers, fixed fire extinguishing systems (i.e. CO2, dry chemical systems), fire fighting
vehicles and hazard detection and monitoring system.
The fire protection system intends to control and/or extinguish fires by a private fire brigade and no external fire fighting sources will be readily available.
The fire protection system is designed based on the assumption that there will be a single major leak of flammable liquids or gases at a time in the plant and fire will not occur simultaneously at different places.
4.1 General System Description
Fire protection of plant equipment is designed considering effectiveness of the following extinguishing and cooling agents.
4.1.1 Desalinated Water as Fire Water
Water is normally used as a diluting, cooling and fire extinguishing agent.
As a cooling agent, fire intensity can be controlled by applying water to equipment exposed to heat radiation by fire due to its outstanding heat absorption characteristic. Additionally, water can extinguish Class A fire such as wood, paper and textile fire.
Water shall not be applied onto LNG / LPG spill because it will accelerate the vaporization speed of the liquid and enlarge the fire.
4.1.2 Foam
Two (2) types of foam are being employed: Aqueous film forming foam (AFFF) for the low expansion foam and Synthetic foam for the high expansion foam.
The low expansion foam is applied to extinguish flammable or combustible hydrocarbon liquid fires by smothering and cooling the liquid surface to prevent re-ignition. AFFF agents will be used for the low expansion foam system and are synthetic concentrates based on fluorinated surfactants and foam stabilizers. The foam produced forms a barrier against air and oxygen as well as develops an aqueous film on the liquid surface to halt vaporization. For this plant, AFFF concentrates are available for proportioning to a final concentration of 3 percent by volume with either fresh water or sea water.
The high expansion foam is applied to LNG fires by suppressing the vaporization speed and controlling the intensity and size of the fire developed. Synthetic foam agents suitable to the high expansion foam equipment will be used and are composed of hydrocarbon surfactants. The foam produced develops a stable frozen foam layer that insulates the LNG and blocks radiation feed back to the fuel by excluding additional air. For this plant, the synthetic foam concentrates are diluted to a final concentration of 3 percent by volume with either fresh or sea water.
Both AFFF and synthetic foam concentrates are compatible for use with the dry chemical powder for hydrocarbon liquid fires and LNG fire.

20-JUL-20064.1.3 Dry Chemical Powder
Dry chemical powder is applied to extinguish small spill hydrocarbon fires and fires on flammable solids. Class BC type dry powder is used in plant outdoor area suitable for hydrocarbon and LNG fires. For this plant, the Class BC type dry powder shall be a potassium bicarbonate based agent, which is called Purple K and used for the portable and wheeled fire extinguishers, fixed dry chemical system and the triple agent fire truck.
Class ABC type dry powder is used inside the buildings. For this plant the Class ABC type dry powder shall be a monoammonium phosphate based agent, which is called Foray and used for the portable fire
extinguishers.
Dry powder agents extinguish a fire primarily due to the interaction of the particles to stop the chain reaction that takes place in flame combustion. It shall be noted that after the application of the dry chemical agent, re-ignition of flammable material after the flame knock down may occur, if the ignition sources are not cooled down or removed.
4.1.4 Carbon Dioxide
The mechanism by which carbon dioxide (CO2) extinguishes fire is by reducing the concentration of oxygen
(smothering) and the vapor phase of the fuel or both in the air to the point where combustion stops.
Carbon dioxide is used for the total flooding fire suppression systems for the sealed under-floor cableways in the Local Control Rooms (LCR) and Main Control Building (099-B-1001), gas turbine enclosures and emergency diesel generator enclosures.
Wheeled CO2 extinguishers are installed near the main substation and main control building. Portable CO2
extinguishers are installed inside buildings where electrical rooms are located.
The discharge of CO2 in fire extinguishing system creates serious hazard to personnel such a suffocation and
reduced visibility during and after discharge period. Pre-discharge notification should be provided to prevent personnel from being exposed to an atmosphere made hazardous by CO2 discharge.
4.1.5 Fire Water Capacity 4.1.5.1 Fire water storage
(1) Utility Area Fire Water Source
The fire water storage tank shall be the Desalinated Water Tank (064-TK-1001). Net working capacities are as follows:
(a) 4160 m3 (4160000 L) : Four (4) hours fire water
(b) 8282 m3 (8282000 L) : One (1) week plant consumption excluding potable water demand The total fire water capacity is based on the requirement of fire water demand at the rate of 1040 m3/hr (17333 l/min) for a minimum of four (4) hours continuous fire fighting operation.
(2) Sea Water Intake Area at the LNG Loading Deck and Trestle Area Fire Water Source
The fire water source shall be sea water in the sea water intake and used as a back up fire water source during emergency operation when Utility Area fire water source is not available. The sea water back up system can supply a total of 1040 m3/hr (17333 l/min) equivalent to the rated capacity of two (2) sea water supply pumps.

Automatic high expansion foam system is provided for each spill impounding basin in the LNG Process Train 1 and 2, LNG Loading Deck and LNG Storage Tanks. The foam supply system mainly consists of atmospheric foam concentrate tanks, balanced pressure proportioning system, foam distribution piping, foam generators and deluge valve system.
6.14.1 Foam Proportioning System
The balanced pressure foam proportioning system comprises of atmospheric foam tanks, foam proportioner, water driven foam pump and necessary control system that will produce 3% foam solution by mixing synthetic foam concentrate into water flow at the proportioner. A balanced pressure foam proportioning skid is provided at each area.
1% to 3% Synthetic foam concentrate is employed for the high expansion foam system.
A deluge valve system, which is of hydraulic operated Viking deluge valve Model J – 1 with electric release, is provided for each high expansion foam system. This type of deluge valve shall be automatically activated upon receipt of a signal from the cryogenic spill detector or 2oo2 alarm signals from flame detectors. In case, that one of the flame detectors is faulty, the fire detection by one (1) flame detector will automatically activate the high expansion foam system.
Automatic activation via cryogenic spill detector will result in an LNG spill alarm (TAL) in the HDMS VDU in the MCB (099-B-1001) and Fire and Emergency Station (082-B-1001). While, activation of the flame detector will result in a fire alarm indication in the HDMS VDU in the MCB (099-B-1001) and Fire and Emergency Station (082-B-1001).
Upon automatic activation of the high expansion foam system, actuation alarm (PAH) from the pressure switches (PSH), downstream of the deluge valves will be available in the HDMS VDU in the MCB (099-B-1001) and Fire and Emergency Station (082-B-1001).
High expansion foam system can be remotely opened and closed from the HDMS Operation Board in the MCB (099-B-1001) by hand switch activation of the deluge valves. Deluge valves can also be closed and opened manually via emergency release valve at the deluge valve trim.
During a foam discharge operation, once the required foam depth of 0.6 m over the LNG liquid surface is achieved, the system shall be operated manually and intermittently by local on – off switch located near the spill containment basin to maintain the foam depth.
After automatic activation, the deluge valves will be automatically closed overriding the flame or LNG spill detection to prevent premature depletion of the foam concentration and safe guard against expanded foam over flowing from the LNG spill basin in cases where the operators are not aware of the automatic foam discahrge. The approximate time to close for each system will be as follows:
(1) LNG Process Train – 1 : 60 seconds (2) LNG Process Train – 2 : 60 seconds (3) LNG Loading Deck : 90 seconds (4) LNG Storage Tank (071-TK-1001) : 90 seconds (5) LNG Storage Tank (071-TK-1002) : 90 seconds
