Abstract: "FPSO +CTV + ordinary tanker" new offloading operation has a double risk of collision and leakage. Existing researches only consider the accident as an orderly occurrence of single event or superposition of potential factors. To solve this problem, FRAM was used to analyze the risks in the CTV transfer operation from the system perspective. First, the human factors, technical factors, and organizational factors having the potential to cause an accident are identified based on common performance conditions of FRAM. Then,functional performance changes were evaluated to determine the key operations and accident evolution process. Finally, prevention and control barriers against accidents were established. The results show that there are 25 kinds of risk factors and 2 key operation aspects in CTV transfer operation, and that the comprehensive quality of the operators, the berthing technology of CTV, and the communication effect between CTV and FPSO are the key factors inducing accidents.

Key words: floating production storage offloading(FPSO), functional resonance accident model(FRAM), cargo transfer vessel(CTV), offloading operation, risk factors, risk control barrier
