Petrochemical

In the petrochemical industry, long-term profitability depends on three critical factors: technical design excellence, absolute control of industrial risks, and the ability to decarbonize existing assets without compromising production flows.

Thanks to solid expertise in complex project management and multidisciplinary engineering, ZEnergy Consulting supports operators and major contractors in achieving their strategic milestones. Whether conceptual feasibility studies, FEED (Front End Engineering Design), detailed engineering, or heavy modernization of offshore and onshore installations, we convert your complex technical challenges into major economic opportunities, in compliance with the most demanding international standards (ASME, API, EN).

Discover below how our cross-functional, results-oriented approach secures your investments (CAPEX/OPEX) and accelerates your operational transition.

🚀 Our Approach: Value-Driven Transversal Engineering

Optimizing or decarbonizing a petrochemical infrastructure cannot be done in silos. Our approach is based on the convergence between technical excellence, risk management and financial performance (CAPEX/OPEX).

1. Native Multidisciplinary Integration

We ensure smooth and continuous coordination between teams Process (process dynamics simulations, material balances, Flow assurance), Piping (flexibility calculation according to ASME B31.3 / EN 13480 codes), Structure And Industrial Safety. Each design change is immediately analyzed through the prism of its overall impact on the system.

2. Risk Management & Rigorous Compliance

In severe or high-risk environments, safety dictates performance. We integrate risk management into the heart of the design process from the initial phases. By leading and facilitating international regulatory reviews (HAZID, HAZOP, LOPA, SIL, HIPS), we secure the integrity of your assets and operators while ensuring full regulatory compliance.

3. ROI-Focused Engineering (Design to Value)

Each technical solution proposed is arbitrated according to its real economic impact. We don’t just design compliant systems: we optimize designs to minimize manufacturing and installation costs (CAPEX), minimize the duration of production downtime (shutdown) and maximize energy efficiency to reduce future operating costs (OPEX).

4. Innovation & Pragmatic Energy Transition

We transform environmental constraints (reduction of greenhouse gases, flare closure) into opportunities for operational gains. By combining new technologies (such as the integration of innovative ejectors) and proven rehabilitation methodologies (such as composite pipeline lining), we extend the life of your existing infrastructure at a fraction of the cost of a new installation.

🏆 Real Impact: Coordination Successes

🌊 World First: Underwater Pipeline Repair by Internal Lining (Total)

The Challenge: Propose an innovative solution to rehabilitate an underwater crude oil transfer pipeline between two offshore platforms in Denmark, in order to avoid the extremely costly construction of a new line.

Coordination: As project manager, I led the conceptual feasibility study by coordinating a multidisciplinary engineering team. We validated the mechanical resistance of the composite liner under creep conditions (lifespan of 20 years), carried out advanced safety analyzes (HAZID, HAZOP, HIPS) and precisely quantified the budget envelope for the work.

The Results: A world technological first would make it possible to extend pipeline life by 20 years, of reduce the duration of production shutdown by 6 months and generate a overall saving estimated at several tens of millions of euros compared to the installation of a new line.

🚢 FPSO Decarbonization Modification Projects (detailed engineering)

The Challenge: Recover flare gases from the FPSP vessel to reduce greenhouse gas emissions. Closure of the flare changed all of the vessel’s process parameters, requiring a complete reassessment of existing equipment, piping and safety valves.

Coordination: As Engineering Manager of the project, I managed the detailed engineering by synchronizing the Process, Piping, Structure and Industrial Safety teams. I also participated directly in equipment design studies and risk reviews (HAZID, HAZOP, SIL).

The Results: Delivery of a complete and secure technical file, allowing the successful integration of the new gas recovery loops while guaranteeing the compliance and profitability of the asset.

📉 Feasibility Study for the Reduction of Greenhouse Gases by Closing the Flare of an Offshore Platform

The Challenge: Validate the technical and economic feasibility of flare closure on an offshore platform in Denmark, under strong space and existing equipment constraints. The project required the integration of innovative ejector technology to recover the hydrocarbons usually burned.

Coordination: As Engineering Manager of the project, led a team of multidisciplinary experts (Process, Safety, Structure, Economics). Participated in HAZID risk analysis and overall system optimization to overcome platform constraint bottlenecks.

The Results: Drafting of a feasibility report which made it possible to secure approval from Total headquarters and the release of a budget of tens of millions of euros. The study demonstrated possible profitability: a payback period of a few years over the asset’s remaining 10-year lifespan.
