Due to the many variables involved in the process, it still remains challenging to quantitatively evaluate the maintainability of vessel equipment. In this context, a new model, by employing the fuzzy comprehensive evaluation method based on analytic hierarchy process, was proposed to help evaluate vessel equipment maintainability. The evaluation index of vessel equipment maintainability was determined with special focus on factors influencing the maintainability. Then the method was applied in self-developed system that aims to quantify maintenance of vessel equipment and analysis the process of maintenance work, and it was subsequently verified by the practical examples. Results show that maintenance determined using this method are consistent with that observed within actual condition. This further certifies that this method can reasonably and effectively quantify the maintainability of vessel equipment.
