Integrity Management Solutions


Our Integrity Management team has expertise including In-Service Pressure Testing, planning, design, and execution, as well as Direct Assessment, and Direct Examination.  The group also provides In-Line Inspection execution and management and IM program development.

The Integrity Management team also includes a large Corrosion Control group of NACE-Certified Technicians to ensure all testing, assessments, surveys, and inspections meet and exceed industry requirements. Capabilities of the Corrosion Control team include Annual Survey, Close-Interval Survey, AC/DC Interference Testing, DCVG & ACVG Surveys, Coating Conductance Testing, general site inspection, coating application inspection, and specification writing and review.


LSC conducts Direct Assessment projects using External Corrosion Direct Assessment (ECDA), Internal Corrosion Direct Assessment (ICDA), and Stress Corrosion Cracking Direct Assessment (SCCDA) methods. LSC’s Integrity Management Team works closely with our Corrosion Control Team to plan and execute the pre-assessment, indirect inspection, and post-assessment steps. Our Non-Destructive Examination (NDE) Technicians execute the direct examination step. LSC’s engineers evaluate existing data, interpret results, and recommend appropriate actions through each step of each iteration in the ongoing ECDA process. Our approach balances long-term system integrity with cost-effectiveness.


LSC routinely performs direct examinations of clients’ excavated pipelines in the field, primarily through visual, magnetic particle, and ultrasonic testing (including shear wave and Phased Array techniques).  In addition, our NDE Technicians assess coating defects, perform basic coating inspection, collect samples for MIC testing, and measure soil resistivity, pH, and pipe-to-soil potentials.


LSC’s Integrity Management Team provides clients with a full range of services related to the Integrity Management Programs required by 49 CFR Parts 192 and 195 from the review & revision of a client’s existing program to full development of a comprehensive written Integrity Management Program (IMP) for hazardous liquids, natural gas transmission, or natural gas distribution.


LSC plans and executes pressure tests for several pipeline operators using both hydrostatic and pneumatic techniques. In addition to performing pressure tests as an integrity assessment method on existing pipeline systems, we perform pressure tests as part of commissioning for new mainline, station, and facility piping.


LSC reviews records and written programs in preparation for regulatory audits. We participate in inspections, aid in responses to inspection findings, and update written programs following an inspection. In addition to Integrity Management Programs, we provide this service for inspections related to Operations & Maintenance, Operator Qualification, Public Awareness, Damage Prevention, Control Room Management, and Drug & Alcohol programs.


LSC’s Integrity Management Team provides a wide range of ILI services tailored to each project.  Whether anomaly evaluation at a dig site or full-scale project management of an ILI run, we do it all.  Our services range from planning and execution of the run, raw data review, and dig selection to field examination and repair method evaluation.

LSC offers comprehensive corrosion control services based out of our Duluth and Minneapolis offices.  Our Corrosion Control Team of motivated engineers and NACE-Certified Technicians is committed to accurate data collection, professional client representation, and proficient documentation and report generation. Our corrosion control experience includes applications for submerged metallic pipelines, above-ground and underground storage tanks, compressor and pump stations, lift stations, municipalities, and mining facilities.

Corrosion control is a vital management plan to sustain the integrity of the pipeline and/or structures.  We understand that a successful corrosion program typically depends on a combination of control procedures including: proper materials selection for the application, coating, cathodic protection, stray current bonds, dielectric insulation, vigilant construction practices and corrosion inhibitors. Our Coatings and Cathodic Protection Teams evaluate, develop, recommend, and implement these methods.

By successfully implementing a corrosion control plan, we ensure clients can protect, maintain, and monitor their equipment.



  • Installation and restoration-to-service planning
  • Cathodic protection system maintenance
  • Stray DC interference testing, mitigation, and bond inspection
  • AC corrosion modeling and mitigation
  • Annual test point survey
  • Close-interval survey
  • DCVG, ACVG, and current attenuation surveys
  • Soil resistivity and terrain survey

We understand coatings are the first line of defense against corrosion.  Protective coating systems maintain the integrity of new structures while mitigating corrosion on existing facilities.

Our experienced inspectors, designers, managers and engineers offer a wide range of services to assess and manage our clients’ needs.  Our NACE-Certified Coating Inspectors provide on-site inspections utilizing state-of-the-art technology, test equipment, and instrumentation.

We provide competitive, high-level service to ensure compliance with technical and organizational specifications.  We implement corrosion control programs that will ensure the integrity of our clients’ assets.

Our team provides integrity solutions to meet corrosion control needs. We develop a fundamental cathodic protection and prevention system to extend pipeline life. To ensure these systems operate as designed, we monitor and evaluate processes, provide design services, and support installation and commissioning to deliver comprehensive cathodic protection systems.

Our engineering resources include a strong cadre of cathodic protection system experts in design, maintenance, and remediation of a wide array of cathodic protection systems. Our technicians routinely perform Close-Interval Surveys (CIS), Direct Current Voltage Gradient (DCVG) surveys, Alternating Current Voltage Gradient (ACVG) surveys, annual test point surveys, bond inspections, AC/DC interference surveys, and other related field work to meet and exceed industry requirements.
