TANK PROTECTION SYSTEMS

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?

TANK PROTECTION SYSTEMS

• Lightning strike

• Electrical storms

• Frictional sparking

• Static discharge

• Uncontrolled hot-work

• Overfilling

• Outside sources (bund area/neighbouring tank)

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

Foam Systems

• Principle: covering the surface

• Environmental issues

• Burn-back < > application rate

• Different philosophy than early response

• Different ways of application

TANK PROTECTION SYSTEMS

Oil & Gas:

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

• Tankpit coverage

• Bladder-tanks / Mixingunits
