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.

01

Survey & Data Collection

Assessment of structure condition, coating performance, environmental conditions, and interference to define protection requirements.

02

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
