Offshore structures play a significant role in extracting non-renewable resources such as crude oil and natural gas. However, these facilities that drill, explore, extract, store and process petroleum and natural gas create environmental hazards and are not cost-effective. Therefore, to produce cleaner energy and mitigate anthropogenic pollution into the environment, the world is shifting towards Renewable Energy Resources (RES) and policies. This is largely subtended by the Paris Agreement and efforts of the United Nations Framework Convention on Climate Change where more countries are becoming receptive to the need to stabilize global Greenhouse Gas Concentrations. In this study, the use of renewable energy for powering an offshore structure is evaluated to determine its feasibility and practicality in real world applications. The site used was an unmanned platform with an average load of 10 kW for each hour per day, with 2.4 kWh energy per day and a peak load of 18 kW per day. The system was modeled and analyzed using the HOMER Pro software. A diesel /photovoltaic (PV) based hybrid system was designed for an unmanned offshore natural gas platform to replace the sole diesel-based electric generation. The Homer Pro simulation software was used to evaluate and select the most cost optimal PV system for the site. This optimal PV system was then compared with the business as usual diesel generator scenario using the same software. The parameters like net present cost (NPC), cost of energy (COE), renewable fraction, and diesel fuel consumption were considered to analyze the technical and economic aspects of the system. From the analysis of the results, it was found that the PV system has high initial capital but has a low net present cost as compared to diesel generation. The HOMER Pro suggests that the 4.8kW of the solar/diesel hybrid system for a 10kW average load as an optimized model because of the low NPC comparatively.
