About Marc

Technical director and industrial maintenance consultant with nearly 30 years of experience in critical environments: SEVESO / ICPE refinery, energy, technical infrastructure, retail, and multi-actor industrial sites.

I intervene on issues related to operations, maintenance, reliability, and safety of complex technical installations, with a strong field and process safety culture.

My career combines:
– 9 years in Shell / Petroplus refinery on high-energy installations,
– 14 years of independent technical management within B8 Énergies,
– missions of technical coordination, HV/LV supervision, sensitive project management, and operational arbitration in constrained environments.

I support my clients on:
• maintenance and operational continuity,
• technical supervision and multi-stakeholder coordination,
• compliance and safety of installations,
• industrial risk management,
• technical management of complex projects,
• analysis of degraded situations and resolution of critical issues.

Accustomed to demanding environments: SEVESO, ICPE, ATEX, HV/LV, SSI, SCADA, critical infrastructure, and sites with high service continuity.
