Our services
At Dum Spiro, we provide the full spectrum of pipeline pre-commissioning engineering solutions required to ensure your system achieves safe, compliant, and efficient operation from the very beginning. Our services are built on advanced engineering expertise, cutting-edge technology, and rigorous adherence to international standards, mitigating risk and safeguarding your investment globally.
Engineering & Planning
Success in pre-commissioning begins long before execution. Our dedicated engineering team develops meticulously detailed procedures tailored specifically to your project's unique specifications. We ensure every phase is planned for optimal efficiency and compliance.
- Development of detailed pre-commissioning procedures
- Pre-com subcontractor selection and management
- Equipment selection and sizing based on project requirements
- Comprehensive risk assessments and method statements
- Full compliance with API, DNV, ISO, and client-specific requirements
Pipeline Cleaning & Gauging
To protect asset integrity and ensure smooth operation, we eliminate debris and construction residues left inside the line. This phase verifies the physical integrity of the pipeline, confirming it is free from obstructions before testing.
- Mechanical and chemical cleaning to remove debris and construction residues
- Gauging runs to verify the pipeline's internal diameter
- Detection of ovalities or obstructions that could compromise pigging or flow
Hydrostatic & Pneumatic Testing
Verifying the strength and leak-tightness of the pipeline system is critical. We perform controlled pressurisation testing with accurate, reliable monitoring to validate structural integrity under operational stress.
- Controlled pressurisation to verify pipeline strength and integrity
- Accurate monitoring and data logging throughout test cycles
- Professional leak detection and reporting in compliance with standards
Dewatering & Drying
After hydrostatic testing, efficient removal of all water is essential to prevent internal corrosion. We reduce the pipeline's dew point to the required specification, ensuring a dry, stable internal environment.
- Efficient dewatering using high-efficiency swabbing or pigging techniques
- High-volume air or nitrogen drying to achieve specified dew point levels
- Continuous monitoring and data verification of moisture levels
Preservation & Inerting
This final phase prepares the pipeline for immediate use or preserves it during a delayed start-up. We use inert gases and preservation strategies to maintain internal cleanliness and prevent long-term degradation.
- Nitrogen purging and inerting to prevent oxygen ingress and subsequent corrosion
- Maintaining internal cleanliness until final commissioning
- Development of long-term preservation strategies for delayed start-ups
