Offshore and Marine Fire Suppression Nozzles

Protection of offshore drilling platforms, well heads, tanker vessels, and other marine environments


Marine applications include deluge, foam, and water wall systems where the nozzles are subject to extreme weather conditions and exposure to seawater.

Selecting a Marine Fire Nozzle:

Important factors to consider:

  • Size & shape of target object or area
  • Applicable design specifications and requirements
    • Required protection type:
      • Extinquish, containment, or cooling
    • Required flow rates/coverage densities
    • Allowable run-down
  • Potential wind drift
  • Nozzle material requirements
    • BETE is able to manufacture nozzles in a wide range of materials suitable for off-shore and marine applications
  • Available nozzle mounting locations
  • Available pressure drop (∆P) across the nozzle
    • ∆P = supply pressure at nozzle inlet - process pressure outside nozzle
  • Our experienced engineers can help determine which nozzle will perform as required with your design details
    • BETE is pleased to offer assistance in selecting nozzles and materials to meet the detailed specifications, required nozzle performance (K-factor (flow vs pressure), pattern / coverage, droplet size, etc.) and documentation requirements associated with approved water spray deluge systems
    • However, as a nozzle manufacturer, BETE Fog Nozzle Inc. cannot assume responsibility for the design of life/safety systems

Common Marine Fire Nozzle Uses and Industries:

  • Offshore platforms and drilling rigs
  • Well heads
  • Engine rooms
  • Storage compartments
  • Magazine compartments
  • Ship decks
  • Cargo and tanker vessels
  • Fuel storage tanks
  • Water walls
    • Flare booms
    • Escape routes
