Fuel scarcity has remained persistent in the Nigeria polity even as a net exporter of petroleum. This challenge has been subjected to various policy reforms by different administration to curb the menace in Nigeria as both privately and publicly managed marine terminal operators are constantly retooling to mitigate fuel scarcity and implement the fuel subsidy reforms of government. The aim of this study is to evaluate and compare the relative performance of 3 publicly and 3 privately managed marine terminals in the execution of RPEA and DSDP reforms of government over the period of 2012 to 2020. Data Envelopmental analysis model was adopted to analyse their relative efficiencies over time. The result revealed that the 3 publicly managed maritime terminals were efficient once respectively under OPA/RPEA (Jonathan’s tenure) while the publicly-managed maritime terminals were efficient both during OPA/RPEA (Jonathan’s tenure) and DSDP (Buhari’s tenure). The study shows that the privately managed marine terminals performed more efficiently in the process of fuel availability in Nigeria.
