Service Overview

HSE Studies

HSE Studies from Green Vertex cover the full suite of structured hazard and risk assessment methodologies used to design and operate high-hazard facilities safely: Hazard Identification (HAZID), Hazard and Operability Studies (HAZOP), Simultaneous Operations (SIMOPS) assessments, Dropped Object Hazard Analysis (DHA) and Quantitative Risk Assessment (QRA).

Process hazard studies are most valuable when they go beyond a compliance exercise to genuinely change how risk is managed on site. Our HSE specialists facilitate HAZID, HAZOP and quantitative risk studies that produce practical, prioritized recommendations your operations team can actually implement.

What We Offer for HSE Studies

HAZID Studies

Structured hazard identification workshops for new and existing facilities. Brings together operations, engineering and safety perspectives in one session.

HAZOP Studies

Systematic hazard and operability studies of process design and operations. Facilitated using recognized guideword-based methodology.

Quantitative Risk Assessment

QRA studies quantifying individual and societal risk levels. Results are presented as risk contours for straightforward interpretation.

Fire & Explosion Risk Assessment

Assessment of fire, explosion and toxic release risks and mitigation. Considers consequence severity alongside likelihood of occurrence.

Safety Case Development

Development of safety cases and safety reports for regulatory submission. Structured to demonstrate risks have been reduced to ALARP.

Action Tracking & Close-Out

Tracking and verification of study recommendations through to close-out. Ensures identified hazards translate into real operational improvement.

FAQ

Frequently Asked Questions

HSE Studies is delivered by Green Vertex's specialist team using internationally recognized methodologies, covering HAZID, HAZOP, SIMOPS, DHA and QRA. The scope is tailored to your facility, project stage and applicable regulatory requirements in Saudi Arabia and the wider GCC.

Timelines depend on facility complexity and the specific study type. A focused HAZID or SIMOPS review may be completed within a few days, while a full HAZOP or QRA for a complex process facility can run over several weeks. We confirm a firm schedule during project scoping.

Many high-hazard facilities and major projects in the Kingdom are required to demonstrate structured hazard and risk assessment under Saudi regulatory and industry requirements. Our team can confirm the specific obligations that apply to your operation.

Green Vertex combines ISO-certified quality management, experienced process safety facilitators and structured methodologies to deliver HSE studies that are rigorous, defensible and delivered on schedule — backed by responsive client support throughout the project.
