Securing the Flow: Strategic Storage and Corridor Design for Maritime Energy Security under Chokepoint Disruptions
Abstract
Maritime disruption planning requires joint strategic storage and transport capacity decisions under uncertainty. We develop a two-stage stochastic multi-commodity network-design model for national energy security that integrates corridor commitments, port--commodity inventories, storage expansion, and scenario-dependent routing for crude oil, LNG, LPG, and fertilizer. The formulation incorporates decision-dependent probabilities, corridor concentration limits, and mean--CVaR risk, admitting an exact MILP reformulation. In a data-anchored India-inspired case study, stochastic modeling outperforms the expected-value policy by 1.35%, with decision-dependent probabilities worth 0.67%. Service levels are heterogeneous: crude and fertilizer maintain full coverage, while LNG and LPG drop to 34.6% and 33.3% under worst-case scenarios. Storage expansion adds 1,775 capacity units across seven port--commodity pairs and reduces active corridor commitments. Sensitivity analyses demonstrate that dependence alters economic exposure while preserving policy optimality, though cost stresses modify first-stage decisions with a maximum regret of 1.1673%.
