Jonathan M. Ross, P.E., is

Director of Engineering of Proteus

Engineering in Stevensville, Md., where he is involved in computer- aided design, engineering and manufacturing for ships and ship- yards in the U.S. and overseas.

This article is based on the paper

Shipbuilding CAD/CAM/CIM:

How World-Class Companies Are

Applying the State of the Art, pre- sented by Mr. Ross and John A.

Horvath (National Steel and

Shipbuilding Company) at the 9th

International Conference on

Computer Applications in

Shipbuilding, October 13-17, 1997.

This paper is largely based on the

Phase I report of the National

Shipbuilding Research Program

Project 4-94-1. Copies of the report may be downloaded from the

Internet (http://www.nsnet.com) or ordered as hard copies from the

Object-oriented database approaches are being used with the intent of developing more expert systems to facilitate the development of designs consis- tent with producibility considera- tions. Hitachi has made productiv- ity studies that suggest only 30 percent of the efforts are con- cerned with actual design work.

The remaining 70 percent are directed toward production of doc- uments, searches for information, inquiries and communications.

Odense performs considerable in- house development work on inte- gration tools between HICADEC and other automation systems used at Odense. Also, the shipyard has developed a host of integration tools for information exchange both within Odense (between design disciplines, materials con- trol, purchasing, production, etc.) and with vendors and subcontrac- tors. On a larger geographic scale, integration between yards and with management locations in cities apart from the shipyards is typical of initiatives in the CIM arena. For example, Odense and

Hitachi maintain an ISDN high performance telephone connection, which is used by Hitachi to access the Odense system and load new versions of HICADEC overnight as necessary. Also, the IHI Kure shipyard is linked to the main office in Tokyo and all manufactur- ing yard LANs are networked together. _Q Circle 230 on Reader Service Card oo > Barnacle Remover

This last application implies the use of a significant degree of intelligence (craftsman "know-how") imbedded into the robot programming and control systems as well as the utilization of interim feedback data for in- process adaptations.

SYSTEMS INTEGRATION

Common to all world-class ship- yards is the move toward greater integration of design, engineering, production, planning, manage- ment and procurement. A fully- integrated approach may be called

CIM (computer-integrated manu- facturing or computer-integrated management). Such an approach is highly reliant upon computer technology. Hitachi's definition of

CIM is the broader computer-inte- grated management rather than the computer-integrated manufac- turing definition. The goal of cur- rent Hitachi Zosen efforts is to integrate the graphical (CAD) data
