We provide mechanical, civil, structural, pipeline, process piping, instrumentation, electrical, construction engineering, and drafting. CCI's engineering services are tailored to fit client’s specific needs.


Pipeline Fitness for Service is a comprehensive analysis of a pipeline’s current and future integrity based on accepted industry methods. The program provides our clients a clear plan for inspection, repair, and mitigation actions, which, when scheduled and completed, ensure safety, reliability, and regulatory compliance. 

  • Data Review and Anomaly Identification

  • Immediate Integrity Assessment

  • Future Integrity Assessment

  • Long-Seam Crack Assessments 

  • PHMSA Compliance

  • Hydrotest Procedures and Validation

  • FEA Corrosion Modeling

  • Remediation Plans

Our engineers use hydraulic simulation to calculate pressure drop and flow distribution through gas and liquid piping systems. The analysis includes expected temperatures, pressures, and volumes flowing through the pipeline, as well as environmental conditions and restrictions along its path. 


Advanced simulation capabilities include transient phenomena such as surge/water hammer calculations.  These methods allow capacity determination and optimal flow characteristics of existing and proposed piping systems as well as the sizing of pipes, pumps, and control valves.


There is a wide array of engineering that goes into supporting pipeline operations throughout an asset’s lifespan. We are experienced with design, modification, testing, repairs, and regulatory support for a wide variety of pipeline assets. Engineering support for pipelines includes:

  • Hydraulic Simulation

  • Design, Permitting and Installation Technical Support

  • Flow Reversal Design and Evaluation

  • Pig Trap Modifications Upgrades

  • Complex Pipeline Abandonments (Land and Marine)

  • Pipeline Relocations and Re-routes (Land and Marine)

  • In-Line Inspection and Data Evaluation (Smart Pigging)

  • Hydrotest Design
