Core products and services

Core Products and Services

Impressed Current Cathodic Protection and Monitoring System

By injecting protective current, the structure to be protected is rendered cathodic, effectively mitigating seawater corrosion. Based on real-time monitoring data, the protection current is adaptively adjusted to reduce maintenance costs and ensure the long-term safety and stability of offshore engineering facilities.

Digital Twin–Based Health Management System

By leveraging digital technologies to process and fuse multi-source sensor monitoring data, an intelligent digital twin model is constructed. Through virtual–physical mapping, real-time status and early-warning information of offshore structures are fed back, enabling intelligent condition diagnosis and smart operations and maintenance of these structures.

Cathodic Protection Numerical Simulation Software

Based on boundary element methods and numerical simulation techniques, this approach enables prediction of potential distributions, optimization of anode layouts, and assessment of corrosion protection performance, thereby shortening design cycles and reducing costs. It is widely applied in marine engineering for corrosion protection, enhancing structural safety and economic efficiency.

Marine and Offshore Engineering Construction Services

Equipped with multi-disciplinary construction personnel specializing in welding, installation, coating, electrical instrumentation, and other trades, we are capable of undertaking prefabrication and installation of special-material pipelines, as well as the fabrication of titanium alloy components—providing comprehensive construction services required for large-scale shipbuilding and offshore engineering projects.
