... to prevent hydrate plugging in subsea pipelines, considering system availability. INTRODUCTION In LNG-FPSO, ensuring flow assurance in subsea pipelines under low-temperature and high-pressure conditions is crucial for preventing hydrate plugging. Hydrate plugging during natural gas production can...

... ABSTRACT This paper discusses some problems on flow assurance of LH16-2 oil fields in the South China Sea. The main difficulty of flow assurance is about wax disposition and hydrate formation for the LH20-2 oil field. If these two problems are not solved, wax and hydrate may block the flow...
