An FPSO (Floating Production Storage and Offloading) is often described as a floating refinery. It is a vessel-type offshore facility that extracts crude oil in deep-sea fields, processes it onboard, stores it in large hull tanks, and transfers it to shuttle tankers for transportation. FPSOs are engineered to withstand harsh offshore environments and continuously changing sea conditions. All piping and tubing systems must maintain crude oil integrity, and every component must endure rough seas and extreme external forces without failure. Hwasein Bolt Industry contributes to offshore plant reliability and safety by supplying high-quality fastening solutions designed for these demanding marine environments.
