Engineering Services – Process Safety & Process plants

Introduction

Engineer Hub provides independent engineering support for industrial gas installations, PtX systems, and process plants. The focus is on technically robust, standards-compliant solutions that are practical to build, operate, and maintain.

The services combine:

• ATEX and explosion safety expertise
• Operational experience in PtX, Power plants and natural gasinstallations
• Design review from an operations perspective
• Compliance support aligned with IEC and EN standards

The objective is not only to ensure regulatory compliance, but to ensure that installations are logical, operable, maintainable, and safe in real-life conditions.

1. ATEX & Hazardous Area Classification

Full Hazardous Area Classification (HAC) studies in accordance with IEC 60079-10-1, including calculation-based zoning and ventilation assessment.

• Identification of sources of release
• Grade of release determination
• Leak rate modelling
• Ventilation effectiveness assessment
• Zone determination (Zone 0, 1, 2)
• Hazardous Area Register preparation
• ATEX zoning drawings review
• Independent third-party HAC review

Deliverables can include complete HAC documentation, zone registers, calculation files, and engineering justification reports suitable for permitting authorities.

2. Explosion & Process Safety Support

• Explosion Risk Assessment support
• Input to Explosion Protection Document (EPD)
• FERA (Fire & Explosion Risk Assessment)
• Fire & Gas detection philosophy support
• Ventilation adequacy review
• Hydrogen dispersion engineering input
• Compliance gap analysis

The approach is structured, standards-based, and suitable for regulatory submission or internal technical governance.

3. Risk & Safety Studies (HAZID / HAZOP)

Structured risk studies to identify hazards early, challenge design assumptions, and define practical risk reduction measures.

• HAZID facilitation and reporting (early project phases, site and interface risks)
• HAZOP support (node definition, deviations, causes, consequences, safeguards, recommendations)
• Operations-focused HAZOP input (maintainability, isolations, access, start-up/shutdown, human factors)
• Action tracking, close-out support, and recommendation quality checks
• Integration with ATEX/HAC findings where relevant

Deliverables can include a structured study report, action register, and engineering input for design updates and permitting packages.

4. Operational Procedures & Safety Systems

Development and review of operational safety procedures tailored to hydrogen and industrial gas installations.

• LOTOTO (Lock Out Tag Out Try Out) procedures
• Permit to Work systems
• Confined Space Entry procedures
• Hot Work control procedures
• Gas testing procedures
• Isolation philosophy and boundary definition
• Start-up and shutdown procedures

Procedures are written with practical field usability in mind, ensuring they are workable for operators and technicians.

5. Operations-Focused Design Review

Engineering review from an operations and maintainability perspective.

• Piping layout review
• Access and maintainability assessment
• Valve positioning logic
• Isolation strategy review
• Drain and vent placement review
• Instrument accessibility evaluation
• Practical constructability assessment

The focus is on identifying design elements that may technically function but are impractical, unsafe, or inefficient in daily operation.

6. Hydrogen System Engineering

• Electrolyser system integration support
• Buffer vessel and pressure system review
• Purge and inerting strategy development
• Hydrogen piping specification review
• Interface review between legacy and new systems
• Support during permitting processes

Special focus is placed on hydrogen installations where flammability, dispersion behaviour, and regulatory requirements demand higher technical rigor.

7. Independent Technical Review

Independent review of third-party engineering deliverables, including:

• ATEX documentation
• HAC registers
• Vendor design packages
• Risk assessments
• Process safety documentation

This service is particularly valuable during project execution phases where objective technical validation is required.

Working Method

• Structured and standards-based methodology
• Transparent engineering assumptions
• Calculation-supported conclusions
• Clear documentation suitable for audits
• Defined scope and boundary conditions

Engagement Models

• Fixed-scope project delivery
• Hourly technical advisory
• Independent peer review
• Long-term technical support agreements
