Installation of Impressed Current Cathodic Protection (ICCP) System for Buried Pipeline

Overview

A major pipeline operator sought to enhance the corrosion protection of a critical buried steel pipeline through the installation of a new Impressed Current Cathodic Protection (ICCP) system. The objective was to provide long-term corrosion control, improve asset integrity, and extend the operational life of the pipeline in accordance with industry standards and the client's integrity management strategy.

The project involved the complete engineering, procurement, installation, testing, and commissioning of a new ICCP system designed to deliver effective cathodic protection along the pipeline route.

Planning

• Pipeline route assessment.
• Soil resistivity investigations.
• Groundbed sizing and location selection.
• Preparation of construction drawings and installation procedures.
• Development of commissioning and monitoring plans.

Execution

• ICCP System Installation
• Anode Groundbed Installation
• Transformer Rectifier Installation
• Pipeline Bonding and Connections
• Test Station Installation
• System Testing and Commissioning

Operational Challenge

• Protecting the entire pipeline length from external corrosion.
• Achieving industry-standard cathodic protection criteria.
• Operating efficiently under varying soil conditions.
• Providing long-term service with minimal maintenance.
• Supporting future integrity management activities.
• Minimizing construction impact on surrounding facilities and operations.

Outcome

• Successful installation and commissioning of a new ICCP system.
• Achievement of required cathodic protection criteria.
• Enhanced protection against external corrosion.
• Improved pipeline integrity and reliability.
• Reduction in future corrosion-related maintenance requirements.
• Establishment of long-term corrosion monitoring capability.
• Improved operational safety and asset sustainability.
