The evaluation method of LNG seafarers' competency based on the FSPA

In order to ensure the safety and efficiency of the transportation of LNG carrier, and for the lack of evaluation method of LNG seafarers' competency, the evaluation index system of professional competency of LNG seafarers has been established. By using the questionnaire data that obtained from the adoption of intuitionistic fuzzy entropy method dealing with the importance of index, the objective index weight is obtained. Then on the basis of the obtained index weight, the fuzzy set pair analysis method is used to evaluate the professional competency of LNG seafarers in an objective and comprehensive manner. The verification result shows that this method effectively overcome the influence of the subjective component on the evaluation in the evaluation process results; The full consideration of the uncertainty of objects and the adoption of diversity parameter measuring this uncertainty make the evaluation results more rational and scientific.
