Pipeline baseline assessment

Soil stress and excessive operating temperatures can damage pipe coating and expose pipe to external corrosion. Water and corrosive contaminants in the product stream can cause internal corrosion damage. High operating stress levels in conjunction with environments conducive for stress corrosion cracking can cause cracking failures. Regular pipeline assessment is critical in order to mitigate these issues. our company offers engineering assessment, data analysis and management for baseline assessment and reassessment programs.

Threat Assessment

A threat assessment helps pipeline integrity management professionals identify the types of possible threats to the pipeline system. Our company offers data analysis, management and engineering assessments for identifying and ranking various threats to pipeline integrity. Our survey work is in the pipeline industry and incorporates a full spectrum of survey techniques: • Close interval pipe-to-soil potential surveys (CIS) • DC voltage gradient - (DCVG) surveys • AC voltage gradient - (ACVG) surveys • Electromagnetic surveys - PCM • Sub-meter GPS locating depth-of-cover • Continuous soil resistivity surveys (electromagnetic ground conductivity) • Linear polarization resistance corrosion rate measurements • Stress corrosion cracking (SCC) investigations

Pipeline ROW & Installed Crossing assessment

• We have extensive experience with the remediation of cased pipeline crossings. • We also have experience with inspecting both new construction and maintenance work being performed by pipeline contractors or third party pipeline companies or contractors within or adjacent to your pipeline right of way. • Our technicians can protect your assets by being on site as your representative to ensure that these companies and contractors are in compliance with crossing and proximity agreements and following correct ground disturbance procedures to prevent pipe contacts or other potential damage while these companies are working in, around, and on top of your pipeline and within the pipeline right of way. • Typically third party utilities and contractors do not fully appreciate the scope of the safety certification and documentation requirements needed when they are working in proximity to pipelines.
