One discipline. Every critical industry.
Our solutions are engineered for the unique pressures of each environment — from reactor cooling lines to subsea pipelines and buried water basins.
Oil & Gas
On- and offshore transport lines, flare lines and storage tanks.
Nuclear & Energy
Cooling lines, reactor vessels and high-pressure injection.
Chemical Plants
Cooling-water lines and essential processing infrastructure.
Water Companies
Pipelines, underground basins and water-flow infrastructure.
Marine & Subsea
Subsea pipelines, offshore platforms and marine structures.
Underground Infrastructure
Buried pipelines, cellars and basin integrity.
It isn’t just rust.
It’s alive.
Microbiologically Influenced Corrosion is metal loss driven by living microorganisms. Hidden inside biofilms, they reshape the chemistry at the metal surface — concentrating attack into deep, localized pits while the surrounding steel still looks healthy.
It remains one of the least understood — and most misdiagnosed — forms of corrosion, which is exactly why it has caused so many high-profile failures worldwide.

Know your adversaries
Sulfate-Reducing Bacteria
Anaerobes that breathe sulfate and exhale corrosive hydrogen sulfide — the most notorious driver of MIC on pipelines, tank floors and offshore steel.
Acid-Producing Bacteria
Excrete organic acids that concentrate beneath deposits, attacking the metal surface directly in a classic under-deposit mechanism.
Iron-Oxidizing & -Reducing Bacteria
Build mound-like tubercles and dissolve protective oxide films, opening the oxygen-starved galvanic cells that drive aggressive pitting.
Methanogenic Archaea
Methane-making archaea that can pull electrons straight from steel — a recognized direct electron-transfer corrosion pathway.
The 5-step integrity process.
From the first analysis to the final inspection, we manage the entire asset lifecycle — predicting the threat, engineering the defense and proving it holds.
Analyse
We examine the asset — basins, flow lines and field coupons — to identify the corrosion cells and mechanisms in play.
Predict & rank risk
Predictive modelling and risk assessment quantify the threat and rank it across your infrastructure.
Engineer the solution
We select the most cost-effective, cutting-edge defense — coatings, CP, composite repair or monitoring — fit for purpose.
Apply & protect
Certified teams deliver the fix with no welding, no cutting and no production interruption.
Monitor & inspect
Continuous monitoring and regular inspection keep the asset compliant with end-user and international standards.
Three tracks. One standard of mastery.
From microbial corrosion to cathodic protection and ASME-compliant composite repair — small-cohort, hands-on programs that end in recognised certification.
Who should attend
Engineered protection, delivered on site — from the Netherlands to Angola.
Watch HydroSeal Global in operation across the Middle East and Africa: onshore pipelines, marine structures, storage tanks and water infrastructure — from field inspection to live, no-shutdown composite repair.
From the classroom to the wellhead.
Real assessments, real assets, real training — on platforms, pipelines and storage systems across our regions of operation.
Guided by engineering authorities.
Our leadership is built from NACE-certified Fellows and PhDs who have helped rewrite the standards for corrosion prevention on a global scale.

Less corrosion. Lower emissions.
Industry across Africa and the Middle East carries some of the world's highest emissions intensity — and corrosion is a hidden contributor. Leaks, flaring, unplanned shutdowns and premature asset replacement all burn carbon. By monitoring assets continuously, specifying the right material and coating systems, and training the people who operate them, we cut emissions and raise productivity at the same time.
Monitor, don't react
Fiber-optic detection and predictive inspection catch loss of containment before it becomes a leak — or a flare.
Right system, longer life
Engineered coatings, cathodic protection and composite repair extend asset life and avoid the heavy carbon cost of replacement.
Competence cuts carbon
Certified operators run plants more efficiently — turning training into lower emissions per barrel, tonne and megawatt.
Corrosion already costs the world an estimated 3.4% of GDP every year — and managing it well is one of the most overlooked levers for industrial decarbonization.
Build the expertise to stop corrosion before it starts.
