Techno-Economic Assessment Power Supply in Offshore Platform by Renewable and Conventional Source

Technical and environmental challenges resulted from an off-design running condition of processes on a platform is an important issue. The weakness of strategies to stop or decrease the amount of the greenhouse gas emission production rate in the Persian Gulf is another important matter of concern which is intensively increasing. Recently, modern methods of energy generation from available renewable potentials near offshore platforms are suggested in the literature. Integration of renewable energy converters with offshore oil and gas platforms can solve both problems with machinery and environment to an acceptable extent. In this study, the economics of an offshore complex installed in the Persian Gulf is subjected to two different power generation systems. The first case defines the present condition in which the total power demand of the complex is supplied by burning the associated extracted natural gas on board the platform in its thermal power plant. The second case considers a wind farm located near Bardekhun in Bushehr province to be connected to the complex power network and shares its renewable source generated power with the platform. The economics and relative emission production of both cases are compared. Wind speed average and wind turbine power generation are considered having uncertainties. Monte Carlo Simulation (MCS) method is used to consider those uncertainties in outcomes. The second case is found obviously more beneficial however there are some conservative assumptions included due to a shortage of data and limitations which makes it more attractive.
