HAZOP Studies & Process Hazard Analysis EPCM Services
Tundra Engineering provides structured HAZOP studies and process hazard analysis (PHA) services as part of our integrated EPCM delivery model for oil and gas facilities across the global energy industry. Our multidisciplinary teams combine process, mechanical, controls, and operations expertise to identify credible deviations, evaluate safeguards, and reduce operational risk from early design through facility start-up.
By embedding formal hazard reviews into the engineering workflow, we help operators proactively manage process safety risks while minimizing late-stage design changes and costly rework. Our approach ensures that hazard identification, operability review, and risk mitigation remain aligned with real operating conditions and regulatory expectations throughout the project lifecycle.
Structured HAZOP & PHA Methodology
Effective hazard analysis requires a disciplined and well-documented methodology. Tundra Engineering facilitates comprehensive HAZOP and PHA workshops tailored to project phase, facility complexity, and regulatory requirements. Our teams prepare detailed process narratives, P&IDs, and cause-and-effect documentation so participants can focus on credible deviations and practical safeguards.
Our process safety review capabilities include:
- Hazard and Operability Studies (HAZOP)
- Hazard Identification (HAZID)
- Layer of Protection Analysis (LOPA)
- Safety Integrity Level (SIL) assessments
- What-If and overpressure risk evaluations
Each session is led by experienced facilitators who understand real-world operating constraints, including startup, shutdown, and brownfield tie-in risks common across oil and gas facilities. Recommendations are captured in structured action registers that integrate directly into downstream engineering and project controls.
EPCM Integration & Cross-Facility Risk Management
Unlike stand-alone studies, Tundra Engineering integrates HAZOP outcomes directly into the broader Engineering, Procurement, and Construction Management (EPCM) execution framework. This ensures identified risks are engineered, tracked, and closed prior to commissioning rather than remaining as unresolved study items.
Our teams routinely support greenfield developments, brownfield modifications, and Management of Change (MOC) programs where process risk must be managed alongside ongoing operations. We also coordinate closely with related systems such as Oil Battery EPCM Services to ensure upstream treating, vapor handling, and custody transfer facilities remain properly safeguarded as projects evolve.
For organizations seeking a single accountable partner across both analysis and implementation, Tundra Engineering delivers practical process safety support aligned with real project execution requirements.
Compliance, Operability & Lifecycle Assurance
Process hazard analysis delivers the greatest value when it supports long-term operability and regulatory compliance. Tundra Engineering structures each HAZOP engagement to align with applicable process safety expectations while maintaining focus on production reliability, maintainability, and safe facility operation.
Our lifecycle approach supports periodic revalidation, ongoing asset integrity programs, and continuous improvement initiatives. By combining rigorous hazard analysis with disciplined EPCM execution, operators gain improved visibility into process risks while maintaining confidence in evolving operating conditions.

Whether supporting a new facility, brownfield upgrade, or ongoing risk management program, Tundra Engineering delivers practical, execution-focused HAZOP services tailored to each client’s risk profile.
What is a HAZOP study in oil and gas projects?
A HAZOP study is a structured process hazard analysis used to identify potential deviations, safeguard gaps, and operability risks in oil and gas facilities. It helps project teams improve process safety, validate design assumptions, and reduce operational risk across the EPCM project lifecycle.
When should a HAZOP or PHA be performed?
HAZOP and PHA reviews are typically conducted during FEED, detailed engineering, and Management of Change (MOC) stages. Performing studies early allows operators to address hazards proactively, strengthen safeguards, and avoid costly design changes later in the project lifecycle.
How does EPCM integration improve HAZOP outcomes?
Integrating HAZOP within the EPCM framework ensures identified risks are tracked, engineered, and closed before commissioning. This coordinated approach improves contractor alignment, supports regulatory compliance, and helps oil and gas facilities maintain safe, reliable long-term operations.
