Abstract: The submarine collective escaping capsule is an innovative emergency equipment for lifesaving purposes. Owing to the lack of statistical data，the risk evaluation of submarine collective escaping capsules is difficult to perform through conventional methods. Aiming at the problem，this paper combines two distinct calculating procedures to form an innovative model for risk evaluation. Particularly，the calculation of the risk grade is based on expert weights，and the calculation of the risk probability is based on the fuzzy set theory. Focusing on the key technology of submarine collective escaping capsules，a preliminary risk evaluation is conducted. The results agree with those obtained from similar foreign equipment，which validates the applicability and reliability of the proposed evaluation model.
