The single point mooring system of oil tankers adopts solitary point arrangement，so there are no land facilities to rely on.In case of an accident，only motor ships are used for emergency protection.Therefore，the configuration for fire-fighting and oil spill emergency facilities of the most credible accident is crucial.According to the Code for Fire Protection Design of Oil and Gas Chemical Terminals，combined with the characteristics of single point mooring，this paper introduces the concepts of pool fire and safety protection distance.It also put forward the allocation requirements for fire boats.For the characteristics of no fixed oil boom during loading and unloading operation，it is proposed that self-configured oil spill emergency facilities should meet the requirements of Class I protection capacity.The calculation method and minimum configuration requirements of oil spill emergency facilities are provided by comparing the Guidelines on the assessment of ship-source oil's response capability and the Requirements of safety operations for oil tankers at single point mooring.
