There were no related papers to study about that training ship's bridge was designed for safety navigation and efficient navigation training. Therefore, at first, on this paper, we grouped domestic training ship's bridge layouts into three classes like as "the front and the rear-type bridge layout", "the twin deck-type bridge layout", and "the single-type bridge layout" by mutually layout type between main bridge and training bridge. Furthermore, we investigated working type of navigation training on each bridge layouts through the questionnaire, and extracted merits and demerits for each bridge layouts to be going on operation and training at the same time. At last, we presented new type training ship's bridge model to improve demerits and to elevate merits above mentioned.

Usually, domestic training ship's bridge was designed for safe navigation and efficient navigation training. In this paper, we grouped domestic training ship's bridge layouts into three classes such as "the front and the rear-type bridge layout", "the twin deck-type bridge layout", and "the single-type bridge layout" by layout type between main bridge and training bridge. Furthermore, we investigated how to operate navigation training according to the type of bridge layout through the questionnaire, and extracted merits and demerits of each bridge layout in combination of normal operation with navigation training at the same time. We presented new type of training ship's bridge model to improve demerits and to elevate merits.

Collision fragility analysis of offshore bridge by ship was performed. Collision velocity and angle were chosen as random variables then collision of 18,000DWT and 30,000DWT ships with bridge was analyzed. Displacement response surface of bridge by ship collision was estimated by varying ship velocity from 2 m/s to 7 m/s. Using the result of reliability analysis, fragility curves of collision was established and risk of offshore bridge to collision velocity as median and log-standard deviation was presented.

A Collapse of bridge by ship's collision to the bridge post may lead a great calamity. This paper investigates on avoiding collision between a ship and bridge by improvement of environmental factors, submitting a counter plan of reducing collision effect by triangular type of collision protecting bar and ship maneuvering skills. Putting up collision protecting bar fences of triangular type around the bridge posts would decrease the collision impact force by 75 percent.

To propose an ergonomic layout on the bridge, this study conducted a usability evaluation on the on-bridge navigational equipment of a college training ship that is in use at present. Through the usability evaluation on the training ship navigators, the possibility of operational errors with navigational equipment, the possibility of readout errors with display devices and even the effect of navigational equipment on navigation were evaluated beyond the scope of existing layouts, which adopt only the importance and usage frequency of navigational equipment. By taking ergonomic variables into consideration, this study suggested an optimized layout for on-bridge navigational equipment using a mathematical programming model.

When designing a ship, ergonomic considerations are crucial when minimizing a navigator's fatigue due to the burden of work, and to appropriately operate the navigational equipment for each given situation by helping the operator to understand the surroundings as well as the physical functions of the ship. However, insufficient consideration of ergonomic elements in the actual design of ship Bridges is lowering the performance of safe navigation and allows for the possibility of operation or readout errors. Consequently, these errors lead to an increase in maritime accidents. Therefore, this study conducted a usability evaluation on the importance of and the usage frequency of navigational equipment, their influence on actual navigation, and the possibility of error upon operation or readout between training ship officers, to derive an optimized layout that includes the consideration of ergonomic factors for on-Bridge navigational equipment, which are currently arranged differently according to their type or size. The optimized layout of on-Bridge navigational equipment was carried out based on the evaluation results, using the Lingo program. Through the process of optimization, revised layouts of on-Bridge navigational equipments(control and display device) were suggested, considering emergency situations(ship collision, stranding, fire and explosion, sinking, etc.) during navigation.

Recently the large sea bridge's construction crossing harbor and main ship's route have been propelled in the domestic so that it is active for the smoothly traffic flow of inland transportation and road user's convenience. However, it can bring about the trouble to ensure marine traffic safety if it is built that sea bridge's construction sets to an economy principle in the extension of the land road system. We're adopting Ship Handling Simulation in representative method for the influence assessment of marine traffic safety and danger elements beforehand. This research attempts to show the problems through the comparison and analysis of the reports relating to the sea bridge construction for 4 organization possessing Ship Handling Simulation. Finally, We offer the necessity of standardization on performing and assessment method of simulations.

A study on theergonomic design of the automated ship's bridge and console layout was carried out through this paper. The goal of this study is to find out the effective and ergonomic optimal design solutions of bridge layout hence to reduce the duty officier's workload and increase the safety of navigation. The conventional bridge layouts and modernized Integrated bridge layouts were compared using several factors. To use human factors, an ergonomic control panel layout system based on constraint satisfaction algorithm wa squoted. And the integrated ergonomic bridge layout was converged and applied to the redesign of the navigational console layout.

The paper describes measurement techniques for an acoustic transfer characteristic of ship's bridge stimulated by a whistle sound The response sounds, according to the opening-shutting conditions of bridge doors for Training Ship ‘SAENURI’, are measured by B＆K 2260D equipment, and then the frequency responses are extracted by B＆K 7830 software. To evaluate the measured transfer characteristic, the 128th order FIR (Finite Impulse Response) filters, containing the different frequency characteristics, are constructed based on the frequency sampling-based design method Using evaluation indexes with six scales, psychological assessments by five subjects are carried out with test sounds which are obtained from convolving the source signal with FIR filters. As results of tests, the test sounds gives $A_S$ 3.3∼4.7 which means the psychological sense of ‘it is almost similar sound as original ones in a real world’, and thus it is clearly seen that the proposed method can be used for the measurement of an acoustic transfer characteristic of ship’s bridge.

A ship can be considered as a large human-machine system and the interaction between worker and system affects the work performed and its efficiency. Inside the bridge of a ship, there exist many auditory signals as well as visual signals. However, only a few studies have been performed related to human recognition to alarm systems in bridge. In this study, auditory icons and abstract sounds are compared to find more effective means of alarm systems. the study result shows tint auditory icons are recognized faster than abstract sounds. This result is expected to be used as a basic data for developing performance criteria of auditory display inside bridge and for designing integrated ship bridge alarm system.
