Recently, there are many sea bridges which is under construction or planned to connect the island with the land in coastal sea. From the viewpoint of navigation safety, it would be the best to build the main span of bridges as wide as possible. But it may not be possible due to geographical or economic reasons.
To construct the bridge on the navigation route, consideration factors for navigation safety must be investigated and examined from the viewpoint of ship maneuverability preferentially.
In this study, the FMSS(Full Mission Ship handling Simulator) of the Korea Maritime University(KMU) was utilized as a tool of analyzing the data acquired from ship's maneuvering. It provides a unique opportunity to check the ship handler's subjective stress level and to collect detailed data including the ships' tracks of passing under the sea bridge. In addition, the assessment of the navigation safety for a ship passing under the sea bridges is evaluated from the proximity, control and subjectivity.
In the conning ship handling simulator, experienced masters and pilots conducted the modeled vessels along the designed channel and under the sea bridges.
This study aims to prepare safety assessment for approaching navigation and safety review in passing under the sea bridge according to the procedures. Examination factors such as environment, a ship type and the bridge with width were arranged accordingly about 6 sea bridges and then analyzed with comparison and assessed synthetically as using the results of simulation.
Further researches on maneuvering ships in various condition will be necessary for making individual rules for each special case.
