Raft deliver LNG tank cooling and car deck drencher-systems. Drencher nozzles are fitted, to provide
sufficient water coverage, prevent radiant heat from spreading and to cool down surfaces
such as steel structures and various equipment.
Car decks are covered with different types of water based suppression systems, depending on the
surrounding conditions and local regulations. Closed car decks are generally covered with low
pressure water mist, while open car decks represents different conditions that require other types
LNG TANK COOLING
The use of Liquified Natural Gas (LNG) as fuel is becoming more and more frequent in the maritime
industry. LNG is highly flammable, which makes the fire protection system crucial consideration
when constructing the vessel.
Drencher and High velocity nozzles placed around the LNG tanks to provide sufficient coverage
of water to cool the surface of the tanks and their surroundings.
Fire protection systems for LNG tanks on open deck:
Provide cooling of the LNG tanks in case of fire
Isolate the fire and prevent its spread
Effectively extinguish any fire in the tank surroundings
