Safety Engineering
Functional Safety Services
Independent functional safety engineering and assurance for oil and gas facilities — from hazard identification through to SIL assessment, SIS design, and safety lifecycle management.
Our Expertise
Protecting People, Assets, and the Environment Through Rigorous Safety Engineering
Hokol Energy Enterprise provides specialist functional safety services that help operators and project teams demonstrate that their safety instrumented systems and protective layers meet the required risk reduction targets. Our safety engineers work across the full IEC 61511 safety lifecycle — from initial HAZOP and LOPA studies through SIL determination, SIS design verification, and pre-startup safety reviews. We bring independent, technically rigorous assurance to every engagement, ensuring that safety-critical systems perform as intended when they are needed most.
Our Functional Safety Capabilities
HAZOP & Risk Assessment
Facilitation and documentation of HAZOP studies, What-If analyses, and quantitative risk assessments — identifying process hazards and establishing the risk reduction requirements for each scenario.
LOPA & SIL Determination
Layer of Protection Analysis to determine the required Safety Integrity Level for each Safety Instrumented Function, ensuring the SIS design targets are correctly established and documented.
SIS Design & Verification
Review and verification of Safety Instrumented System design — logic solver selection, sensor and final element specification, architecture assessment, and SIL verification calculations.
Functional Safety Assessment
Independent Functional Safety Assessments at key lifecycle phases — confirming that the safety lifecycle has been followed and that the SIS is fit for purpose prior to startup.
Safety Lifecycle Management
Development and maintenance of the functional safety management system — safety plans, competency management, MOC procedures, and periodic proof test and revalidation programmes.
Pre-Startup Safety Reviews
Structured pre-startup safety reviews (PSSR) and safety critical element verification to confirm that facilities are safe to commission and operate before first introduction of hydrocarbons.
Our Functional Safety Process
A four-phase approach aligned to the IEC 61511 safety lifecycle — from hazard identification to operational assurance.
Hazard Identification & Risk Assessment
HAZOP facilitation, consequence analysis, and risk assessment to identify all credible hazard scenarios and establish the tolerable risk criteria against which protection layers are evaluated.
SIL Determination & SIS Specification
LOPA or risk graph studies to determine required SIL targets, followed by development of the Safety Requirements Specification defining the functional and integrity requirements for each SIF.
Design Verification & FSA
Independent review of the SIS design against the SRS, SIL verification calculations, and Functional Safety Assessment to confirm the design meets all safety lifecycle requirements.
Operational Safety Assurance
Pre-startup safety reviews, proof test procedure development, and ongoing safety lifecycle support — ensuring the SIS continues to meet its SIL targets throughout the operational phase.
