The use of Diesel Generators (DGs) and gas turbines to power oil rigs is characterized by pollution due to the emission of harmful gases like carbon dioxide, very high noise levels, high maintenance costs, and the inability to start the platform if the DG fails. Offshore wind energy generation system provides a viable alternative means of powering the
oil rig and can also be integrated to operate in parallel with gas turbines. However, offshore wind energy might fail if not properly designed due to the high variability of wind resources. Hence, the objective of this work is to design offshore Wind Turbine Generator (WTG) energy generation system, DG, and hybrid DG-WTG for the
black start of an offshore oil rig. The designed
energy systems are simulated using HOMER Pro. Furthermore, the performance of the simulated systems was evaluated using the electrical production, unmet load, and emission profile as the performance metrics. The results of the hybrid DG-WTG powered
black start revealed that ۱۵۰kW DG generated ۳۲۲,۰۷۱kWh/yr representing ۶.۷۷% of the total generation and ۱.۵MW WTG generated ۴,۴۳۴,۶۳۲kWh/yr representing ۹۳.۲% of the total generation. The comparison of the emissions from DG and DG-WTG revealed that ۲۹۴,۰۵۸kg/yr, ۱,۹۴۵kg/yr, ۸۰.۹kg/yr, ۹.۰۲kg/yr, ۷۲۰kg/yr, and ۶۸۸kg/yr of CO۲, CO, UH, PM, SO۲, and NO, respectively, were released into the atmosphere by DG-WTG which is very low compared to ۹۶۹,۱۲۹kg/yr, ۶,۱۰۹kg/yr, ۲۶۷kg/yr, ۳۷kg/yr, ۲۳۷۳kg/yr, and ۵۷۳۹kg/yr of CO۲, CO, UH, PM, SO۲, and NO, respectively, released into the atmosphere by DG. The sensitivity analysis revealed that while the electrical production of ۱۰۰kW and ۵۰kW DGs decreased with an increase in WTG height, the electrical production of ۱.۵MW WTG increased with an increase in WTG height. It was further revealed that the higher the WTG height the smaller the quantity of the emission released into the atmosphere.
