Built the economic case for consolidating eight OECS ports into an Eastern Caribbean Port Authority, with the OECS Port Committee and the Antigua and Barbuda Port Authority.

Result

Eight-port consolidation case

An economic model for consolidating eight OECS ports, a Heads of Government strategy deck and a Prime Ministerial brief, and the OECS Ports Network / Trade Logistics Strategic Blueprint for the ECCB Growth and Resilience Dialogue 2026.

Phase 1 (delivered, winning the retained Phase 2 mandate): capital-structure analysis comparing blended-led, grant-led and equity-led scenarios, a Cabinet briefing gap analysis and a revised 15-page Cabinet briefing. Phase 2 (in progress, from July 2026): engaging DFC, USTDA and EXIM (including a USTDA feasibility-grant application), designing the UK FCDO Investment Incentive Agreement route, re-testing affordability, scoping grant-funded gap-closure studies, and building the Full Business Case.
