A STUDY ON FUNCTIONAL REQUIREMENT IN SHIP ORERATION

为了提高船舶运行安全，国际海事组织根据船舶安全运行功能要求的概念，提出了《国际安全管理规则》。本研究的主要目的是从船上调查研究人类和安装操作系统的船舶的功能需求。在这个项目中，研究人员和幸运的是，有很好的机会设计和建造一艘新的沿海货船，具有集成的操作系统和测量船舶运动、环境状况、人类任务等的记录系统。第一年，船舶建造成功，船舶性能和仪器有效性；第二年，对船舶运行进行了详细的测量和船舶操作人员的听力研究，建立了船舶运行详细测量结果的数据库。在机舱和驾驶台的监控/操作控制台，也对机械操作的详细方面进行了调查。研究了操作者和安装了操作系统的船舶的功能，得出结论：安装了操作系统的船舶可以在一个人的控制下安全运行；此外，为了研究船舶在港口区域的操纵情况，利用虚拟现实系统开发了新的操纵模拟器，并成功地验证了该虚拟现实模拟器的有效性。

To improve operation safety of ships, the International Maritime organizatio proposed the International Safety Management Code, being based on the concept of functional requirement for ship safety operation. The main aim of the present research is to study on functional requirements for human and ship with operating systems from the on-board investigation.In this project, the investigators and fortunately a great opportunity of designing and constructing a new coastal cargo ship with the intergrated operation system and also the recording system to measure ship movements, environmental situations, human's tasks and so on. In the first year, the ship was successfully constructed and the ship's capability and the effectiveness of the instrumentation.In the second year, detailed measurements of ship's operation and hearing studies for ship's operators were carried out and the data base of detailed measurement results of ship operations. In the engine room and the monitoring/operating console in the bridge, detailed aspects of machinery operations were also investigated. The funcitons of human operators and the ship with operating systems were investigated and it is concluded that the ship with the developed operating systems can be safely operated under one man control.Besides, to investigate maneuvering aspects of ships in port area, the new maneuvering simulator was developed by use of virtual reality system and the effectiveness of such a virtual reality simulator was successfully confirmed.
