As a new concept of high speed marine transportation, the Techno Super Liner is expected to realize and also her safe long-term navigation should be assured previously. On the other hand, a modern domestic mariner with an one-man bridge operation system is under developped to achieve comfortable accommodation for mates and highly economic performance. The new navigation support system for one-man operation is also expected to assure safe long-term navigation and to have sufficient support aids to reduce the operator load. In this paper we assess the safety of the long-term navigations of a high speed large cargo ship and a one-man operated modern domestic tanker using a maneuvering simulator. These navigations are assessed from the view of safety mergins for the long-term watch. As the results, both of the high speed large cargo and the modern domestic tanker can be operated safely in long-term navigations by the one-man bridge operation system. The main function of the support system for the high speed cargo operation is a collecting the imformation about the navigation environment, and the main function for the modern domestic tanker is a planning the collision avoidance maneuver.
