Analytical Study of the Integration of Renewable Energy Systems in Nigerian Offshore Platform Power Management

Offshore oil and gas production platforms rely almost exclusively on hydrocarbon-fuelled gas turbine and diesel generator systems for power generation, contributing to greenhouse gas emissions and fuel logistics costs. This study analytically investigates the technical feasibility and economic viability of integrating renewable energy systems, specifically solar photovoltaic and wind turbine installations, into the power management systems of fixed offshore platforms operating on the Niger Delta shelf. A techno-economic analysis methodology was employed, combining energy demand profiling from operational records of two representative shallow-water production platforms with irradiance and wind resource data from offshore meteorological stations in the Gulf of Guinea. Hybrid power system simulation was performed using established energy simulation software to model renewable energy penetration levels and storage system sizing. Economic assessment was conducted using discounted cash flow analysis. Results indicate that solar photovoltaic integration at a penetration level of between twenty and thirty percent of platform electrical demand is technically feasible within the physical constraints of existing platform topside areas, with an estimated payback period of between six and nine years at current diesel fuel costs. Wind resource is found to be variable but supplementary to solar during cloud cover periods. The study contributes the first quantitative techno-economic case for renewable integration on Nigerian offshore platforms.
