Development of the database for damages of ship structures by using multimedia

本文利用多媒体技术对船体结构损伤数据库(案例库)进行了研究。数据库建设的目的是促进船舶设计、维修人员、船东和监管机构等不同角度对结构损伤信息的沟通和共识，具体而言，对各种损伤信息进行系统分类，并利用多媒体技术构建数据库。作为一种多媒体技术，使用了船体结构和损伤的三维计算机图形、船体结构的漫游、损伤的图像等。其次，开展了支持船舶维修管理的船舶结构损伤信息系统的研究。利用多媒体技术和面向对象的数据库技术，构建了单壳油轮原型系统。并研究了建立此类损伤信息系统所需的损伤分析方法。

In this this study, the research on the database (the case database) of damages of ship hull structures is carried out by using the multimedia technology. The objective of the construction of the database is to promote communication and common understanding of information on structural damages within the different standpoint such as ship designers and repair persons and shipowners and supervision organization, etc. Concretely, various damage information was systematically classified, and the database by multimedia was constructed. As a multi-media technology, three-dimensional Computer Graphics of the ship structures and damages, walk-through in ship hull structure, images of damages, etc. are used. By using such technoloty, it is possible to construct the database which can be easily understood by users.Second, the research on the information system for damages of ship structures, which supports the maintenance or management of ships, is carried out in this study. By using the multimedia technology and object oriented database, the proto-type system for a single hull tanker is constructed. Also, the necessary analysis method about damages was studied for the construction of such damage information system.
