Because of complex ocean environment, underwater vehicles are facing many challenges in navigation safety and precise navigation.

Aiming at the requirements of underwater navigation safety, this paper presents an evaluation method of underwater ocean environment safety situation based on Dempster-Shafer (D-S) evidence theory.

Firstly, the vital ocean environment factors which affect the underwater navigation safety are taken into account, and a novel basic probability assignment (BPA) construction method of ocean environment factors is proposed according to their characteristics.

Then, a new transformation method of BPA to decision-making probability is put forward to deal with the uncertainty degree.

Furthermore, the super-standard weight is applied to preprocess the BPA, and D-S combination rule is used to acquire the evaluation result by fusing the preprocessed BPA.

Ocean environment safety situation index is obtained by quantizing the evaluation grades.

Finally, experimental results show that the method proposed has the superior practicability and reliability in actual applications.
