Deluge Testing and Verification

Full Spectrum Deluge Testing and Maintenance Services

Deluge verification is the testing and maintenance of deluge systems to ensure compliance to design and performance criteria.

Johnson Controls provide the best range of services and expertise to meet the desired standards on Deluge verification comprising:

  • Surveys and inspections
  • System refurbishment and upgrades
  • Wet performance testing
  • Dry performance testing
  • Hydraulic calculations
  • Chemical pipework cleaning

We have a comprehensive team of experienced, highly trained engineers to carry out this specialised work worldwide.

Our unique 5 Year Inspection Test Maintenance (ITM) Deluge Resilience Programme saves clients on average 15%+ by using innovation such as Boroscope inspections and HSE compliant dry testing schedules to reduce long term impacts of corrosion to your system, in turn providing significant cost savings.

Johnson Controls: The power behind your mission.

The majority of firewater systems utilised within the offshore industry are of carbon steel construction. Due to the harsh and corrosive conditions, Iron Oxide, Calcium Carbonate, Salt and Marine fouling will deposit inside the pipework, eventually reducing the capacity of the pipework and blocking nozzles.

Regular flushing of the deluge systems and removal and cleaning of nozzles are only considered a short term solution. By increasing deluge flushing to wash out loose corrosion particles and flakes, corrosive seawater will deposit more marine fouling and salt on the pipe wall. Although this cannot be seen from the outside, an irreversible corrosion process will gradually block the deluge distribution system.
In the event of a fire on an offshore installation, a deluge system with blocked pipework and/or nozzles will hinder both the speed and volume of water released through the deluge system, distributing only the volume of water that the pipework can accommodate. This can be at a potentially under-performing flow rate that the now altered parameters allow.

As a result the deluge system will fail to cool the platform’s process vessels and will not be able to offer platform personnel a safe escape route.

Johnson Controls has been providing deluge verification services as part of our Healthcare Support Programs for over 20 years. We are consistently asked to provide on-going maintenance and testing post verification with the aim of ensuring greater reliability and availability of your safety critical systems, plus preventing expensive pipework replacement.

 

The absence of on-going maintenance could result in part(s) of your system being beyond economic repair. By extending the life of your current firewater system, we provide substantial cost savings against the cost of total replacement and the downtime this incurs.

Deluge Performance Testing

The HSE’s Information sheet No 1/2010 states: It is noted that deluge testing offshore is generally being carried out as required. However, some flow measurements are not being recorded effectively and data recorded is not being analysed to provide the best information for use in optimising maintenance and performance.”

The identification of these safety issues is done through Wet Performance Deluge Testing and to compare the test results with the platform’s Safety Performance Standards including Noding Isometric Drawings, Hydraulic Calculations, P&ID’s. The test results will give clear evidence of the deluge system’s condition and will be used to plan the future maintenance strategy which could be:

Carrying out remedial work such as pipework cleaning or (partly) replacement:

• To continue wet performance testing
• To implement dry performance testing

Our team of highly qualified engineers will discuss the options available to you and provide recommendations based on Industry Standards and your safety case.

Why Johnson Controls?

We constantly review and improve our best practise guidelines in line with industry standards, with the aim of ensuring your assets are in the best possible condition in the event of a worst case scenario. As industry leaders in life safety and asset integrity, we are dedicated to protecting what matters to you most; your people and your assets.
