Cathodic Protection Systems

At OAJ & Company Investment Limited, we provide specialized Cathodic Protection (CP) and corrosion mitigation services designed to safeguard critical steel assets across the oil, gas, maritime, and marine infrastructure sectors. Metal corrosion poses a severe threat to structural integrity, operational safety, and asset longevity. Our engineering team utilizes advanced electro-chemical techniques to convert metal surfaces into protective cathodes—effectively stopping corrosion before it starts.

We design, install, monitor, and maintain both Galvanic (Sacrificial) Anode Systems and Impressed Current Cathodic Protection (ICCP) configurations, along with precision reference electrodes tailored for offshore marine vessels, submerged pipelines, storage tanks, and coastal structures.

Our Cathodic Protection Capabilities

Our Cathodic Protection Capabilities

1. Site Surveys & Field Diagnostics

Before system design or deployment, our engineers conduct comprehensive technical surveys to assess environmental conditions and existing corrosion levels.

• Soil & Water Resistivity Testing: Evaluating environmental aggressiveness around pipelines, vessel hulls, and buried infrastructure.

• Structure-to-Electrolyte Potential Surveys: Mapping potential profiles to identify active corrosion hotspots.

• Pre-Design Assessment: Gathering precise field data to specify exact current requirements for long-term protection.

2. Turnkey CP Engineering, Installation & Supervision

We deliver end-to-end Cathodic Protection solutions tailored to client specifications and international corrosion standards (NACE/AMPP).

• System Design & Material Sourcing: Custom engineering of Sacrificial Anode Systems (aluminum, zinc, magnesium) and Impressed Current (ICCP) systems (anode beds, transformer-rectifiers, and cabling).

• On-Site Installation & Supervision: Certified technicians manage structural attachment, post-weld joint protection, and cabling setup for offshore vessels, offshore platforms, jetties, and underground pipelines.

• Commissioning & Baseline Testing: Energizing systems, setting rectifier outputs, and validating system performance against industry protection criteria.

3. Failure Analysis & System Audits

When existing corrosion protection fails or unexpected material degradation occurs, OAJ provides root-cause diagnostic assessments.

• Root-Cause Failure Investigation: Investigating structural pitting, coating disbondment, stray current interference, or premature anode consumption.

• Remedial Engineering: Designing targeted retrofit and rehabilitation solutions to restore full corrosion control to compromised assets.

• Periodic Monitoring & Compliance Maintenance: Routine potential monitoring and transformer-rectifier checks to ensure ongoing asset protection.

Applications We Protect

• Maritime & Offshore Assets: Ship hulls, marine oil vessels, barges, tugboats, and ballast tanks.

• Energy Infrastructure: Underground and subsea oil & gas pipelines, offshore platform jackets, and storage tank bottoms.

• Port & Coastal Structures: Steel sheet piling, jetties, wharves, and marine concrete reinforcements.
