Hydrotests & Support for Commissioning

Ensuring Pipeline Integrity Through Rigorous Testing and Commissioning Hydrotesting and commissioning are vital components of our comprehensive engineering services at Liu Engineering. These processes validate the design, installation, and overall integrity of pipelines and facilities, ensuring that they are fully prepared for safe, long-term operation.

Why It Matters
Hydrotesting and commissioning are not merely procedural steps; they are critical for verifying the integrity and longevity of your pipeline system. Liu Engineering’s commitment to excellence in these areas means that every project is validated through rigorous testing and detailed documentation. This level of care not only minimizes the risk of future failures but also supports robust asset management and operational efficiency.

Hydrotest Design and Planning
Our hydrotest services begin with detailed planning and design. We develop comprehensive test plans tailored to each project’s specific requirements:

• Hydrotest Objectives:  Clearly defining test parameters, including the pressure levels, duration, and acceptance criteria for each section of the pipeline.
• Water Source and Disposal Management:  Coordinating the sourcing of test water and environmentally responsible disposal or treatment post-test.
• Test Equipment and Instrumentation: Specifying the necessary instrumentation to accurately monitor pressure, flow, and other critical parameters during the hydrotest.
• Safety and Emergency Protocols:  Developing rigorous safety protocols and contingency plans to protect personnel and equipment during testing.

On-Site Hydrotest Supervision
Liu Engineering provides hands-on supervision during hydrotesting to ensure that all procedures are followed precisely. Our experienced engineers are present on-site to:
• System Balancing and Calibration: Fine-tuning the system to ensure optimal flow, pressure control, and integration of all monitoring systems.
• Monitor Test Execution: Continuously monitor test conditions, ensuring that the pipeline is subjected to the required pressures and durations.
• Record and Document Results: Meticulously document test data, including pressure curves, leak detection, and any anomalies observed during the test.
• Implement API Procedures: Ensure that all testing procedures align with API standards, giving pipeline operators confidence in the system’s safety and performance.

Commissioning and Start-Up Support
After successful hydrotesting, our commissioning services guide the transition from construction to full operational status. Key commissioning activities include:
• Pre-Startup Inspections: Comprehensive inspections to verify that all components of the pipeline and facilities are installed and functioning as designed.
• Plan for pipeline packing and purging per API guidelines.
• Final Code Compliance Reviews: Coordinating with regulatory bodies to secure final approvals and certifications.
• Training and Handover: Providing detailed operation and maintenance manuals, along with training sessions for operator personnel. Specialized Pipeline Commissioning Services In addition to hydrotesting, Liu Engineering has extensive experience in commissioning pipelines in accordance with API procedures. We have successfully commissioned projects that include:
• Commissioned Pipelines and API-Compliant Purging: Implementing purge protocols that remove contaminants from the system prior to start-up.
• Gas Distribution Pipelines: Designing, constructing, and commissioning gas pipelines that operate upto 100 psi MAOP, ensuring reliability and safety in distribution networks.

Project Success Stories
Our portfolio features numerous success stories, including projects in the Pittsburgh area where we have supported both gas and water pipeline installations. By meticulously planning and executing hydrotests and commissioning activities, we have helped clients achieve safe and efficient operations while maintaining strict regulatory compliance.
