Protecting, Extending and Optimising Energy Infrastructure
Asset-intensive organisations face increasing pressure to operate aging infrastructure safely, justify life extension decisions, and integrate new energy streams such as hydrogen and biomethane — all while demonstrating compliance within regulated environments.
Penspen helps clients understand, quantify, and manage integrity and safety risk across pipelines, pressure systems, and associated facilities.
Our Asset Integrity & Risk Consultancy supports gas networks, transmission operators, bio-methane developers, terminals, storage operators, and wider energy infrastructure owners.
We work alongside engineering, integrity, and operational teams to translate inspection data, operational history, and risk exposure into structured, defensible decisions that protect people, assets, and reputation.
Contact UsOur Capabilities
We assess the condition, performance, and remaining life of pipeline systems to ensure safe and reliable operation across their lifecycle.
- Pipeline Integrity Management System (PIMS) development
- Risk Base Inspection (RBI) studies and inspection planning
- ILI technology selection and inspection strategy studies
- Fitness-for-Service (API 579 / BS 7910)
- Fracture mechanics and defect assessment
- Corrosion growth and remaining life analysis
- MAOP revalidation and uprating studies
- High Consequence Area (HCA) assessment
- Integrity assessment for repurposed pipelines
We deliver robust, defensible QRA studies to support operational decision-making, regulatory engagement, and investment planning.
- Pipeline QRA (onshore and offshore)
- Facility and terminal QRA
- Individual and societal risk modelling
- Hazard Identification (HAZID)
- Consequence and dispersion modelling
- Failure frequency modelling
- Emergency planning zone determination
- Land-use planning assessments
- ALARP demonstration
Our QRA capability integrates inspection data, defect assessments, and operational history into risk models — providing clear visibility of exposure and prioritised mitigation strategies.
As biomethane injection, hydrogen and carbon capture integration increase, we support operators and developers in managing the associated safety and integrity risks. Clients bring us in when they need to:
- support planning consent and regulatory approval
- demonstrate ALARP for injection facilities
- assess risks associated with high-pressure injection
- understand contaminant and gas quality impacts
- evaluate network interface and overpressure scenarios
- integrate and transition biomethane, hydrogen or carbon dioxide safely into existing infrastructure
- provide independent technical assurance
We help clients move from high-level hazard identification to quantified, defensible risk positions that withstand regulatory scrutiny.
We provide integrity assessment and assurance services for pressure systems and associated facilities.
- Written Schemes of Examination (WSoE)
- RBI programme development
- Structural and piping integrity assessments
- Stress analysis studies
- Failure investigation and Root Cause Analysis
- Independent technical assurance
We help clients understand degradation mechanisms and advise on how to extend asset life safely.
- Corrosion management strategies
- Cathodic protection assessment
- Materials degradation analysis
- Hydrogen and CO2 service readiness
- Life extension justification studies
- Integrity reassessment under new operating conditions
We combine deep asset integrity expertise with THEIA, Penspen’s digital integrity management solution, to deliver clearer, faster risk insight for asset operators. Our consultants translate engineering data into decision-ready intelligence that supports more confident operational and investment decisions.
Our approach includes:
- Data enablement and integration – organising and preparing asset, inspection and operational data so it can be reliably analysed and used to support integrity decisions.
- Executive-ready risk insight – turning complex engineering information into clear explanations of what it means for safety, operations and investment decisions.
- Clear visibility of risks across assets – helping operators identify where the greatest integrity risks exist so they can prioritise inspections, maintenance and investment.
This digitally enabled approach moves beyond traditional reporting, providing operators with clearer line of sight between asset condition, operational risk and strategic decision-making.
We engage with operators to support their operational endeavours, such as:
- Integrity programme management
- Embedded operator technical support
- Integrity strategy development
- Inspection interval optimisation
- Risk-based maintenance planning
- Training and knowledge transfer
- Independent technical review and assurance

Why Clients Choose Penspen
With over seven decades of experience in global energy infrastructure, we understand how assets are designed, how they degrade and fail, and how risk should be quantified and managed.
Our strength lies in integrating engineering integrity, materials expertise, and quantitative risk assessment into a single, defensible framework.
Our teams combine practical field understanding with advanced modelling capability — ensuring solutions are technically robust, commercially pragmatic, and regulator-ready.
We support both brownfield and greenfield assets, helping clients move from reactive integrity management to structured, risk-based, and evidence-led decision-making.
