Building Resilient Offshore Supply Chains: Managing Logistics Disruptions and Project Delivery Under Geopolitical and Market Uncertainty

Abstract

Offshore engineering, procurement, construction, and installation projects depend on long-lead equipment, constrained marine access, port availability, and sequential construction interfaces. These dependencies make project delivery highly sensitive to geopolitical uncertainty, market volatility, route disruption, port congestion, regulatory change, and vessel availability. This paper presents an execution-focused framework that was utilized for managing such disruption practically before it becomes a critical schedule or commercial event. The framework integrates marine logistics planning, contract governance, risk allocation, and project controls into one decision process that can be applied by project management teams, contractors, marine logistics providers, and commercial stakeholders. The methodology is based on case-driven offshore EPC execution experience in which disrupted shipping routes, port constraints, and force-majeure type events affected the movement of critical equipment and materials. The paper organizes the response into five connected steps: anticipate, assess, decide, respond, and learn. Each step links operational information, schedule impact analysis, contract entitlement evaluation, and governance escalation. The analysis shows that alternative routing, secondary port options, vessel substitution, revised cargo sequencing, and earlier stakeholder alignment can help maintain execution momentum; however, each mitigation option introduces its own cost, safety, interface, and contractual consequences. The paper therefore emphasizes decision quality rather than isolated logistics recovery. The main contribution is a practical framework for converting disruption signals into timely project decisions. Instead of treating disruption as either a logistics issue or a contractual claim, the framework aligns supply continuity, entitlement management, and schedule protection. The paper concludes that offshore EPC resilience improves when logistics plans include contingency routes, contract provisions are interpreted early and consistently, decision thresholds are predefined, and project controls provide transparent impact visibility. This integrated approach offers a repeatable model for protecting project delivery under geopolitical and market uncertainty.
