Position Purpose

The Senior Pipeline Integrity Engineer plays a vital role in supporting the Transmission Integrity Management Program (TIMP) and Distribution Integrity Management Program (DIMP) to ensure the continued safety, reliability, and regulatory compliance of Unitil’s natural gas transmission and distribution infrastructure. Working under the Manager of Integrity Management, this position is responsible for conducting engineering analyses, risk assessments, and technical evaluations to maintain the integrity of pipeline assets in compliance with 49 CFR Part 192 and applicable state and federal regulations.

The Senior Pipeline Integrity Engineer executes pipeline integrity assessments, performing system modeling, analyzing threats and risks, and developing mitigation plans to ensure proactive integrity management. This includes supporting inline inspections (ILI), direct assessments, corrosion monitoring programs, Maximum Allowable Operating Pressure (MAOP) reconfirmation, and integrity-related capital projects. The role also requires coordination with operations, regulatory compliance teams, and contractors to implement best practices and maintain compliance with integrity management regulations, such as PHMSA’s MEGA Rule.

As a key technical resource within the Integrity Management group, the Senior Pipeline Integrity Engineer ensures that engineering principles are applied to maintain pipeline safety and operational efficiency. The individual in this role must have extensive experience of pipeline materials, stress analysis, and corrosion mitigation techniques. Additionally, the Senior Pipeline Integrity Engineer is responsible for preparing technical reports, supporting regulatory audits, and contributing to continuous improvement initiatives within the company’s integrity management programs.

Principal Accountabilities

1. Pipeline Integrity Assessment & Compliance (30%): Assist in performing integrity assessments for both TIMP and DIMP, ensuring compliance with 49 CFR Part 192 and state regulations. Support inline inspection (ILI), pressure testing, direct assessments, and other methodologies to identify potential threats such as corrosion, stress corrosion cracking, and mechanical damage. Conduct technical evaluations of assessment results and recommend mitigation actions.
2. Risk Analysis & Data Review (25%): Conduct pipeline risk assessments using industry-standard methodologies, including ASME B31.8S. Analyze data from inline inspections, GIS systems, historical failure records, and operational reports to determine pipeline integrity risks. Contribute to maintaining a robust risk model for transmission and distribution systems.
3. MAOP Reconfirmation & Material Verification (20%): Support the Manager of Integrity Management in reconfirming MAOP in accordance with 49 CFR 192.624. Perform material verification, record traceability (TVC compliance), and pressure testing strategies to ensure regulatory compliance. Maintain documentation of MAOP validation efforts.
4. Corrosion Control & Mitigation Strategies (15%): Support corrosion monitoring programs, including cathodic protection system evaluations, close interval surveys, and internal corrosion direct assessments (ICDA). Review pipeline coatings, corrosion inhibitor programs, and pipeline maintenance practices to ensure longevity of assets. Work with corrosion control personnel and contractors to develop mitigation strategies.
5. Regulatory Compliance & Audit Support (10%): Assist in preparing integrity management documentation for PHMSA and state regulatory audits. Support responses to regulatory inquiries and ensure integrity programs remain in compliance with new and emerging regulations. Maintain organized records of integrity assessments, risk evaluations, and mitigation activities.
