The transition towards sustainable energy sources is driving innovative solutions in the offshore oil and gas industry. The presentation delves into the integration of a Wind Turbine Generator (WTG) into an existing Floating Production Storage and Offloading (FPSO) vessel to reduce carbon emissions. The technical and operational challenges of this integration are discussed, including load balancing, intermittency of wind energy, transformer energization, motor starting, protection coordination, and maintaining operational reliability. The study utilizes simulations with tools like HOMERPRO, ETAP, and PSCAD to assess the technical feasibility of integrating the WTG and Battery Energy Storage System (BESS) into the FPSO power system. Various studies, including load flow, short circuit, motor acceleration, transient stability, voltage ride through, harmonic analysis, protection coordination, and transformer energization are conducted to ensure the effectiveness and efficiency of the proposed system. There is great potential for reducing the operational carbon footprint of FPSOs by incorporating renewable energy sources and using software simulations to address the complexities and considerations involved in such integration.
