At Subsea Corrosion Ltd, we provide specialist cathodic protection (CP) and corrosion engineering services for the offshore, marine, offshore renewables, ports, harbours, and inshore infrastructure sectors.

Our experienced engineers help asset owners maximise service life, minimise maintenance costs, and protect critical infrastructure from corrosion. Whether you require a one-off inspection, a complete CP system retrofit, or long-term maintenance support, we deliver practical, cost-effective solutions tailored to your assets.

Our Core Services include:

System Condition Assessments, Reviews & Audits

We assess the condition and performance of existing cathodic protection systems, identifying deficiencies, verifying compliance with industry standards, and recommending improvements to maximise asset protection.

Corrosion Investigations

When corrosion problems arise, we carry out detailed investigations to determine the root cause, assess the level of risk, and develop effective mitigation strategies that protect your infrastructure.

Site Surveys & Field Data Collection

Our engineers undertake comprehensive offshore and inshore inspections, including:

• Dropcell potential surveys
• Impressed Current Cathodic Protection (ICCP) cable inspections
• Transformer Rectifier Unit (TRU) inspections and testing
• Structural and infrastructure corrosion assessments

CP Troubleshooting & Fault Diagnosis

We identify and resolve faults affecting cathodic protection systems, including electrical continuity issues, equipment failures, damaged components, and underperforming CP systems.

Cathodic Protection Retrofit Design

We design bespoke galvanic anode and impressed current (ICCP) systems for ageing structures, life-extension projects, and infrastructure upgrades, ensuring reliable long-term corrosion protection.

Materials Procurement

We supply high-quality cathodic protection materials, including:

• Sacrificial anodes
• ICCP anodes
• Cables
• Junction boxes
• Monitoring equipment

Project Management

From initial planning through to completion, we manage every stage of your corrosion protection project, coordinating engineering, procurement, logistics, offshore operations, and client communication to ensure successful delivery.

Commissioning & Handover

Following installation, we commission your cathodic protection system, verify performance, complete all required documentation, and provide a smooth handover for operational teams.

Operation, Maintenance & Monitoring

Maintaining an effective CP system is essential for long-term asset integrity. We provide ongoing support through:

• Routine CP inspections
• System monitoring
• Performance optimisation
• Compliance reporting
• Preventative maintenance
• Maintenance planning and scheduling

Protecting Assets for the Long Term

Whether supporting offshore oil and gas, offshore wind, ports, harbours, pipelines, or other marine infrastructure, Subsea Corrosion Ltd delivers practical corrosion engineering solutions that improve reliability, extend asset life, and reduce whole-life costs.
