Functional Safety Consultancy

Safety you can demonstrate, from design to decommissioning.

Independent functional safety expertise for oil & gas, rail, nuclear and manufacturing. We cover the entire safety lifecycle, from SIL determination through to assessment and sign-off, with the rigour and follow-through your safety case depends on.

What We Do

The full safety lifecycle, handled properly.

Every service below feeds the same goal: safety instrumented functions that are correctly specified, verified against realistic data, and maintainable for the life of the plant.

Lifecycle

Safety Lifecycle Coverage

Support at every stage of the safety lifecycle, from concept and design through operation, modification and decommissioning, aligned to recognised functional safety standards.

Specification

Safety Requirements Specifications

SRS documents built on our pre-developed templates, capturing every safety function clearly and consistently so nothing is left ambiguous at handover.

Verification

SIL Verification

SIL verification using the Reliability Block Diagram (RBD) approach, giving a transparent, auditable demonstration that each safety function achieves its target.

Risk Assessment

LOPA

Layer of Protection Analysis with calibrated tolerable risk targets, determining a defensible required SIL level and risk reduction factor for each scenario.

Hazard Study

HAZOP

Structured hazard and operability studies to systematically identify deviations, causes and consequences before they become incidents.

Support

Engineering Virtual Assistance

Remote engineering support and administration, keeping documentation, registers and project records moving while your engineers stay focused on the plant.

Who You'll Work With

Led by experience, not a rota.

Our principal consultant, Andrew Young, has spent his career delivering functional safety across oil & gas, chemical and industrial installations, supported by our wider engineering and administration team.

Standards

IEC 61511 Throughout

Safety systems and functions designed, verified and assessed in line with IEC 61511, across every phase of the process safety lifecycle from FSA stage 1 through to stage 4.

Assurance

Assessment and Audit

Functional safety management plans, gap analysis, hazard assessments at stages 2, 3 and 7, What If analysis and Basis of Safety reporting, plus direct support for clients during HSE interventions.

Delivery

From Paper to Plant

SRS production for a wide range of safety functions, including bespoke software SRS for Emerson DeltaV configurations, through to validation, commissioning and proof testing documentation.

Long Term

Beyond Handover

Failure data recording, functional safety KPIs, extended useful life assessment and management of change, so the safety case stays sound years after commissioning.

People

Competence and Training

Internal and external competence training, from basic functional safety awareness through to hands-on use of lifecycle management tools.

Team

Backed, Not Alone

Andrew leads every engagement personally, with engineering and administrative support behind him, so documentation, records and follow-through never lag behind the site work.

SIF Management

Your safety functions, in a hierarchy you already know.

We manage safety instrumented functions using a familiar structure, so your data mirrors how your plant is actually organised.

Level 01 Site
Level 02 Plant
Level 03 SIS
Level 04 SIF
Living Failure Data

Element data that keeps itself honest.

Through SIFED, our SIF Element Database, element failures and population changes are recorded and reviewed as they happen, not left to drift until the next audit.

  • Record failures as they occur. Element failures and population changes are captured against the assets they belong to.
  • Review with context. Failure history sits alongside the element data, so trends are visible rather than buried in spreadsheets.
  • Automatic propagation. Any change in failure rate is automatically pushed into downstream records, so your SIL verification always reflects reality.
  • Tag management built in. Element and tag data is managed together, letting you reuse proven element data across your assets instead of re-entering it.
