Industrial safety and risk management for ENGIE projects

The Challenge

ENGIE has the ambitious mission to accelerate the transition to a carbon-neutral world
and to develop a diversified energy mix in which renewable energies play a key role. To
achieve this ambition, ENGIE continuously invests in both its existing assets and the
development of new ones. Across its various projects, ranging from lifetime extensions
and upgrades to new builds, ENGIE is committed to maintaining the highest standards
in health and safety.

The Solution

Tractebel provides specialized engineering dedicated to the identification, analysis,
quantification and control of industrial risks throughout the entire lifecycle of the
client’s industrial and infrastructure assets from feasibility and concept design through
detailed engineering, construction, commissioning, operation and modification.
Our services are based on recognized engineering methodologies, international
standards and regulatory frameworks, and are delivered by a team of experienced
safety, and reliability engineers working in a multidisciplinary context. These services
include:

• Hazard identification and risk analysis
  HAZID, HAZOP, e-HAZOP/SAFOP, FMEA/FMECA, SWIFT, bow-tie, and qualitative
  risk assessments to systematically identify hazards, assess initiating events,
  evaluate consequences and define preventive and mitigative barriers.
• Major hazard and quantitative risk assessment
  Major hazard (fire, explosion and toxic dispersion) studies, consequence
  modelling, safety distances and Quantitative Risk Assessments (QRA)
  supporting risk-based design and optimization, land-use planning and permitting
  as well as Safety reporting according to the SEVESO-directive.
• Process and functional safety
  Development of process safety strategies, LOPA, SIL allocation, assessment of Safety Instrumented Functions (SIF), and Safety Instrumented Systems (SIS).
• Explosion and ATEX safety
  Explosion risk assessments, hazardous area classification, ATEX zoning drawings, and Explosion Protection Documents (EPD) for both design and operational phases.
• Project and construction safety
  Definition and implementation of project safety management systems, construction site safety coordination, safety audits, and performance assessments using structured methodologies.
• Asset HSE conformity and occupational safety
  Regulatory compliance assessments of installations and work equipment, occupational H&S inspections, gap analysis against European directives (CE compliance), applicable standards and client and third-party requirements, with actionable remediation plans.
• Reliability, availability and maintainability (RAM)
  Reliability and availability modelling, fault tree analysis (FTA), and semi-quantitative and quantitative assessments to support design decisions, operational availability objectives, and maintenance strategies.
• Incident and accident investigation
  Systematic investigation of incidents and high-potential events, root cause analysis and definition of corrective and preventive actions, compliant with international H&S management standards.

The Impact

Our approach combines participative workshops, desktop engineering studies, and advanced modelling with state-of-the-art software tools, ensuring traceable, auditable and reproducible results. Safety requirements are integrated into engineering specifications, procurement documents and project processes, ensuring consistency between design intent, regulatory compliance, permitting and operational reality.
