A STUDY ON FUNCTIONAL REQUIREMENT IN SHIP ORERATION

为了提高船舶的操作安全性，国际海事组织提出了《国际安全管理规则》，该规则是以船舶安全操作的功能要求为概念的。本研究的主要目的是从船上调查中研究操作系统对人和船的功能需求。在这个项目中，研究人员幸运地获得了设计和建造一艘具有综合操作系统和记录系统的新型沿海货船的机会，该系统可以测量船舶运动，环境情况，人员任务等。在第一年，该船建造成功，船的能力和仪器的有效性。第二年开展船舶作业详细测量和船舶操作人员听力研究，建立船舶作业详细测量结果数据库。在机舱和驾驶台的监控/操作控制台，还对机械操作的详细方面进行了调查。通过对人工操作人员和安装了操作系统的船舶的功能进行研究，得出了安装了操作系统的船舶可以在一人控制下安全运行的结论。此外，为了研究港区船舶的机动问题，利用虚拟现实系统开发了新的机动模拟器，并成功验证了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.
