Abstract: The stability and reliability of the power system of a Floating Production,Storage and Offloading （FPSO） unit play a crucial role in the safe production of offshore oilfields. By applying typhoon-resistant generators and emergency start-up chargers to the FPSO,during the typhoon evasion period,the FPSO can maintain power supply for monitoring and communication systems,etc. The duration of power outage during typhoon evasion has been reduced from the original 60 hours to 15 minutes. After adding the emergency start-up chargers,the start-up success rate of emergency generators during post-typhoon recovery has increased from 70% to 95%,ensuring the rapid restart of offshore oilfields.

Key words: FPSO, typhoon, generator, emergency start-up charger, monitoring, communication, storage battery
