Cathodic Protection
Full Lifecycle Solutions — From Design to Long-Term Performance
From Design to Assured Performance
JST provides complete cathodic protection (CP) solutions — from feasibility and design through installation, commissioning, monitoring, and long-term maintenance.
We combine corrosion engineering expertise with proven technologies — working in partnership with leading industry specialists including Cosasco, GPT, Dairyland Electrical Industries (DEI), Borin Manufacturing Inc., Metalnastri, BAC Corrosion Control Ltd, and Deepwater Corrosion Services.
We don’t just install CP systems — we engineer, implement, and verify solutions that perform where it matters: in the field, over time, under real operating conditions.

End-to-End Delivery
A disciplined, phased approach from initial assessment through long-term asset protection.
Survey & Data Collection
Assessment of structure condition, coating performance, environmental conditions, and interference to define protection requirements.
Design & Engineering
Development of CP systems tailored to asset and operating conditions, including:
- Impressed Current Cathodic Protection (ICCP)
- Sacrificial Anode Cathodic Protection (SACP)
- Groundbeds and anode systems
- Electrical isolation and interference control
- Monitoring and test systems
Utilising proven technologies from

Metalnastri
Anode systems and earthing materials

GPT
Isolation joints, flange insulation systems

Dairyland Electrical Industries
Decouplers, grounding, and protection devices

BAC Corrosion Control
Specialist CP technologies and controls

Deepwater Corrosion Services
Offshore CP installation and subsea execution
All integrated into engineered protection solutions.
Installation, Commissioning & Testing
Deployment of CP systems including anodes, transformer rectifiers, cabling, and test facilities, with verification of protection criteria.
Monitoring, Inspection & Verification
Validation of CP performance through:
- CIPS and DCVG surveys
- Performance testing and system checks
- Integrated corrosion monitoring systems (Cosasco, Borin Manufacturing Inc.)
Offshore & Subsea Execution
Delivery of offshore CP installation and retrofit solutions through specialist execution partners including Deepwater Corrosion Services.
Operation, Maintenance & Optimisation
Ongoing monitoring, adjustment, and optimisation to ensure sustained protection and long-term asset integrity.
Engineered for Performance
Our work is defined by cathodic protection performance. We don’t aim to meet expectations — we engineer, implement, and verify CP systems that perform under real operating conditions.
Our reputation is built on results: Proven delivery. Sustained protection. Long-term client trust.
