Firewater and deluge systems are safety-critical elements vital to the continuous operation of any offshore asset, industrial plant, or energy facility. These systems must function immediately and reliably to control fires and limit their escalation.
Over time, however, the untreated or chlorine-treated seawater used in these systems causes severe internal degradation. Corrosion, scale deposits, and marine fouling accumulate inside the pipework, leading to flow restrictions and blocked nozzles.
We provide specialist internal pipe cleaning and descaling services that significantly improve deluge flow paths in a cost-effective and efficient manner. Our non-invasive techniques restore your system’s integrity without the extreme costs and downtime associated with full pipe replacement.
Deluge systems are normally kept ‘dry’, meaning water is only introduced downstream of the valve during a fire or a wet test.
The primary cause of corrosion and subsequent blockages is the long-term exposure to the seawater that pools in the pipes after these mandatory wet tests. Because there is no airflow to dry the pipes, this stagnant moisture creates a highly corrosive environment. Furthermore, microbial films can form within hours in stagnant untreated seawater, creating locally aggressive environments that lead to severe under-deposit pitting corrosion.
Routine cleaning removes these deposits, preventing catastrophic system failure during an emergency operation.
Don’t let stagnant seawater compromise your emergency readiness. Schedule an assessment to identify and eliminate blockages before your next mandatory test.
We have refined our methodology and advanced tooling to safely descale all types of open-ended pipework without harming the parent material. We specialize in the internal cleaning of:
Whether your facility is an offshore oil & gas platform, FPSO, or onshore industrial plant, our multi-skilled operatives can undertake all work scopes quickly and safely.
Whether you operate an offshore platform or an onshore industrial plant, our multi-skilled team is ready to restore your flow rates safely.
Replacing a highly corroded pipe network is a standard recommendation by many contractors, but it is often unnecessary. If an internal inspection reveals blockages, but the pipes have not yet reached the end of their technical lifespan, cleaning is a far superior and sustainable solution.
Facility managers often worry that chemical or mechanical cleaning might damage older pipes. Extensive research funded by the Health and Safety Executive (HSE) concludes there is no evidence that cleaning mechanically sound deluge pipework results in damage.
Electrochemical testing demonstrated that metal loss from proprietary cleaning solutions over a 24-hour period was exceptionally minimal (around 10 microns), meaning it is highly unlikely to cause perforation unless the pipe is already severely wasted.

Ready to extend your testing cycles, minimize plant downtime, and lower your carbon footprint? Fill out the form below to see how much you can save by choosing cleaning over replacement.
No. Extensive testing shows no evidence that cleaning chemicals will cause perforation of otherwise mechanically sound pipes. Metal loss during the cleaning cycle is negligible.
The major cause of blockages is corrosion products, primarily driven by long-term exposure to seawater pooling in the pipes following mandatory wet testing.
Yes. Experience has shown that cleaning is cheaper than replacing the piping network. It also eliminates the significant costs and operational disruption associated with installing scaffolding and removing large sections of pipe.
If specific sections are too degraded, replacement and repairs are undertaken. We can replace the system with like-for-like materials immediately or upgrade to the latest composite wrap repair technology for rapid and effective leak repair.
Do not wait for a failed wet test or an emergency to discover your deluge system is compromised. Our rapid internal and external inspections provide key information on where problems are most acute.
