TANK PROTECTION SYSTEMS

Tank Fire Protection


Tank Fire Protection• Fire protection on floating-roof tanks• Detection of tank fires• Waterspray Systems• Foam Systems • Solution: CFI Rim seal fire protection• SK2000 Fire Alarm Panel


Disaster


To late !!


Floating roof tanks• Very economical way of storing large amounts of hydrocarbons-products

• World wide very common application since the 1960’s

• Avoid loss of product by floating roof

• Fire-protection?


• Lightning strike

• Electrical storms

• Frictional sparking

• Static discharge

• Uncontrolled hot-work

• Overfilling

• Outside sources (bund area/neighbouring tank)

• Switch loading (e.g. gasoline – diesel)

HOW TO PROTECT A TANK ??


• How to detect?• Response time?• Intervention time required?• Fire Fighting service available?• Full automatic system?

Criteria for tank fire protection


• Low response time• High failure risk• Intervention needed

Visual detection

Detection of tank fires



Flame Detector (UV-IR)• Fast response time• Intense maintenance• Detection range/field?• Intervention needed


Heat Detection Cable• Good response time• Less maintenance• Sensitive structure• Intervention needed



Heat detection installed on Rim Seal


Pneumatic Heat Detection Plastic tube Poly Flo• Good response time• Less maintenance• Sensitive structure• Intervention needed


Glass Bulb GTD• Good response time• Less maintenance• Robust structure• Intervention needed


Poly Flo installed on Rim Seal

Waterspray Systems

• Cooling-down tanks

• Using slotted nozzles

• Prevention of fire-spread / flash-over


Waterspray Systems

• Deluge-systems

• Manual/automatic activation

Cooling by using stationary systemsApplication ratesTank wall protection

16,7 lpm/m (PGS29)

Using the run down principal2 lpm/m2 (IP19)

Tank roof protection2 lpm/m2 (IP19 – PGS29)

Always remember the stiffeners on the tankshell


Foam Systems

• Principle: covering the surface

• Environmental issues

• Burn-back < > application rate

• Different philosophy than early response

• Different ways of application


Oil & Gas:

• Foam over the top by split jet nozzle or foam-chamber

• Tankpit coverage

• Bladder-tanks / Mixingunits

Foam System for fixed roof tank


Foam Systems Tank Pit


Floating roof tanksApplication rate :12,2 lpm/m2

Depending on the height of the foam-dam Foam generator every 12,2 or 24,4 meters

Coneroof tanksAlways calculate a full surface fireApplication rate :4,1 lpm/m2

Tank pitApplication rate :4,1 lpm/m2

Above mentioned value’s are based on NFPA11 – IP part 19 – PGS29


• Fire-testing and R&D on this application/system from 1963 with the use of Halon 1211 (BCF)

• From 1999 with CFI for Rimseal

• Several tests for various customers

• Systems installed on over 3500 tanks in 120 different countries
