Dry Deluge Testing


Clearwater Fire Solutions are exclusive UK agents for Siron Dry Deluge Testing. This technology is patented and has been extensively field tested and is used offshore regularly in the Dutch and UK sectors. Siron Dry Deluge Testing offers the client the justification needed to prove to the HSE and regulatory bodies that the deluge system remains in a fit for purpose condition in between mandatory wet testing.

Many operators are stuck in the cycle of repeated wet deluge testing on an increased frequency to meet the nozzle failure rate criteria rate set out in their Performance Standards. This will only exacerbate the build up of corrosion scale within the deluge system and ultimately cause more issues longer term.

With Siron Dry Deluge Testing used as part of a Fire System Integrity Assurance (FSIA) plan the operator can have complete justification to extend the periods between wet deluge testing out to 5 years or more potentially.

Dry Deluge Testing can be used on all material types and has no limit on the size of the system that can be tested. It is suitable for carbon steel, cunifer, duplex, stainless steel, titanium, flexible hose and fiberbond systems. Deluge systems remain live and online throughout the complete process and at no time is any equipment installed that impedes the flow path of firewater to the protected area.

Dry Deluge Testing Dry Deluge Testing

Siron Dry Deluge Testing has been given a Certificate of Attestation by Bureau Veritas Uk Limited. No other method of dry testing is more efficient or more effective for identifying blockages/partial blockages to pipework and nozzles.

It is also the only available method of testing without water that can quickly identify damaged nozzles, a common failure mode that directly affects the density application rates within the protected area.

Siron Dry Deluge Testing (DDT) Key Benefits:

  • Testing is efficient and has no disruption to normal platform activities
  • Preparation time for DDT is considerably less
  • Pipe wall failures are easier to identify
  • Deluge pipework remains dry mitigating corrosion
  • No new corrosion, salt or marine growth will form in deluge pipework
  • Residual firewater from previous wet tests is displaced from the distribution pipework
  • Sump/drain tanks will not overflow due to excessive firewater discharge
  • No freezing of any firewater in water traps throughout deluge system
  • No water ingress protection is required over sensitive instrumentation or electrical equipment
  • No firewater is discharged onto live plant which eliminates risk of unplanned business loss or shutdowns due to water ingress
  • Blocked and partially blocked nozzles are quickly identified
  • Extensively field proven and used in Dutch offshore sector
  • No complicated electronics are used and equipment has small footprint
  • Less bedspace required resulting in cost saving to client
  • Complete platforms can be tested in days rather than weeks
  • Damaged nozzles are quickly identified due to erroneous spray pattern during DDT
  • Does not rely on systems being clean or having up to date hydraulic calculations and isometric drawings
  • Brings a more scientific approach to all previously available inspection based dry testing procedures
  • System is live throughout process and equipment does not impede flow path of firewater to protected area

There is no more efficient or thorough method of verifying that 100% of the deluge system distribution pipework and nozzles are clear of blockages other than using water.

Compared with traditional wet deluge testing clients can consistently realise a 50% time saving and 60% cost saving when utilising Clearwater Dry Deluge Testing as part of a Fire System Integrity Assurance plan. Our leading Integrity Management software package ensures clients of optimal efficiencies and full compliance of their fire protection systems.
