The number of active sailors is reducing constantly because of aging of active sailors and the rack of appeal for young people. Additionally, optimization of logistic and recession of heavy industries make work conditions of sailor worse. Therefore, we cannot stop the reduction of active sailors and the shortage of active sailors will become a serious problem to keep safe marine transportation. As a solution, a navigation support system (NSS) with advanced automated function is introduced. However, as sailors should act main role of safety navigation, the NSS should be accepted. To get acceptance from them, the support system should reduce task load, establish acceptable human machine interface and. etc. In this paper, first, we discussed the support ways for ship navigation based on human factors. Secondly, we proposed the method to evaluate operational safety of human machine systems with "Level of Safety". Finally, a navigation support system aiming at one person bridge operation(OPBO) is introduced. To develop the NSS, a series of simulator experiments were held in an open sea and in a narrow channel. From the results of the experiments and interviews to active sailors, sailor's demands to the NSS for OPBO were obtained. There are two major demands to the NSS. One is reliable automated function. The other is an effective man-machine interface for the NSS not to disturb watch for other ships. The NSS was designed based on these demands. It adopted many automated functions such as an Electronic Chart Display and Information System (ECDIS), a TRACK PILOT, etc. The NSS also adopted a unique man-machine interface, "Speech Communication". The NSS is well accepted by active sailors and 3 systems were delivered now.
