The paper describes a study of procedures on risk assessment of liquefied gas tankers. The study consists of : a) a proposal of a simple analysis method for the assessment, b) assumption of essential failures and human errors, and their probability involved, and c) an example of the assessment applied the proposal to a 70,000m^3 Ref. LPG tanker. Concludedly, following formula is proposed for safe design of liquefied gas tankers ; P_i⪇A. C_i^<-n> or C_i⪇(P_i/A)^<-1/n> P_i is probability of accident(i) per year. C_i is coefficient of accident effect and takes 100 for the maximum accident assumed, such as collision in a harbour, and reasonably decreases by risk level in each accident. A is 5×l0^<-5> to 10^<-6> and n is 0.7 for Ref. LPG, LNG. Ethylene tankers.
