A greenfield ethylene complex - one of the three largest in the world at the time - approached the final commissioning phase with substantial capital exposure and binding contractual deadlines. The project was executed by a major international EPC joint venture.

Stratum Advisory conducted an independent operational readiness assessment covering contractual obligations, commissioning preparation, infrastructure integration, documentation completeness, and handover prerequisites. The review identified critical infrastructure integration gaps that threatened schedule adherence and created material, financial and reputational risk for investors.

The project was in its final phase, which included commissioning, start-up, ramp-up, performance testing, and contractual handover. Two major international EPC contractors executed through a joint venture - one European, one Asian - with process responsibilities divided between hot and cold process areas.

Construction quality was high and process systems appeared technically ready for start-up. However, capital exposure was substantial and contractual schedules were directly linked to commercial production obligations and product pricing. Any delay in commissioning or failure in contractual handover would result in financial penalties and reputational consequences.

Stratum Advisory was engaged to conduct an independent, cross-functional readiness review covering contractual obligations, commissioning preparation, operational integration, documentation status, and prerequisites for contractual handover.

The assessment covered:

• Progress on completion of critical process units and supporting infrastructure
• Readiness of auxiliary infrastructure and utility systems
• Coordination between EPC contractors and project governance structure
• Readiness of operational organization for asset handover
• Potential investor exposure to additional capital expenditure

The assessment confirmed that technical execution was strong but revealed significant organizational and infrastructure bottlenecks that could materially impact commissioning timelines.

The core risk was not technological failure but contractual and commercial exposure rooted in infrastructure integration delays.

Initial assessment confirmed high construction quality and technical readiness. However, detailed contract analysis revealed that full project execution - including successful contractual handover - was sole responsibility of the EPC joint venture.

A critical integration gap emerged. Upstream and downstream infrastructure - including raw materials storage, product storage, and distribution systems - were progressing under investor responsibility with no synchronized integration oversight relative to core process facilities.

Field assessment and joint walkdown confirmed:

• Upstream infrastructure approximately 35% complete
• Downstream systems approximately 45% complete
• No synchronized integration control
• Approximately 300 specialists mobilized on site generating multi-million monthly overhead costs
• Infrastructure completion estimated at 9–12 additional months
• Escalating litigation and penalty risk

Under these conditions, safe and contractually valid start-up was not feasible. Schedule adherence became unrealistic and commercial exposure escalated immediately.

Based on the assessment, a set of operational and organizational measures was defined to stabilize the project and protect investor capital.

Operational measures included:

• Redefinition of completion priorities on critical infrastructure systems
• Clearer separation of responsibilities between project and operational organizations
• Enhanced coordination between process sections
• Disciplined CAPEX control during project close-out
• Transition of the asset into controlled preservation mode
• Structured monitoring of infrastructure progress under the responsibility of the investor
• Preparation for phased re-commissioning & start-up with a realistic timeline

At the time of assessment, approximately 300 engineering specialists were mobilized on site, roughly 70% international experts. Maintaining full mobilization for an additional 9–12 months was economically unfeasible.

Key organizational measures recommended:

• Demobilization of international specialists in non-critical areas
• Retention of a smaller focused local technical oversight team
• Definition of clear criteria for phased re-mobilization when infrastructure milestones are verified
• Structured commercial dialogue among all parties to prevent dispute escalation

The recommended measures were executed. Demobilization and cost control initiatives proceeded. The asset transitioned to controlled preservation mode, significantly reducing ongoing costs while maintaining technical integrity.

Investor infrastructure completion progressed under structured oversight. The project transitioned from uncontrolled risk exposure to managed stabilization.

Key outcomes:

• Significant reduction in ongoing cost exposure
• Mitigation of escalation into formal dispute
• Preservation of long-term project viability
• Protection of EPC partner reputation

In large-scale petrochemical projects, operational risk often arises not from construction quality but from contractual fragmentation and infrastructure integration blind spots.

When upstream and downstream systems operate outside coordinated control, schedule certainty becomes illusory. Infrastructure synchronization is fundamental to commissioning readiness.

An independent operational review enables investors to identify systemic risks and implement corrective measures before entering the critical commissioning phase. Strategic restructuring of mobilization and risk posture protects capital, preserves reputation, and secures long-term asset integrity.
