A STUDY ON FUNCTIONAL REQUIREMENT IN SHIP ORERATION

为了提高船舶的营运安全，国际海事组织提出了基于船舶安全营运功能要求概念的《国际安全管理规则》。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要求。在这个项目中，调查人员幸运地获得了设计和建造一艘新的沿海货船的大好机会，该货船具有集成操作系统和记录系统，以测量船舶运动、环境状况、人的任务等。在第一年，第二年，进行了船舶操作的详细测量和船舶操作员的听力研究，并建立了船舶操作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。研究了操作人员和船舶的功能，结果表明，采用所开发的操作系统的船舶可以在单人控制下安全操作，并利用虚拟现实系统开发了一种新型的船舶操纵模拟器，以研究船舶在港区的操纵情况，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.
