      <title>DEVELOPMENT OF THREE-DIMENSIONAL MEASURING AND ANALYSIS SYSTEM FOR SHIPBUILDING</title>
      <link>https://trid.trb.org/View/439932</link>
      <description><![CDATA[In process and accuracy control of fabrication and assembly in shipbuilding it is essential to maintain ship quality and construction costs.  Conventional measuring methods using simple apparatus do not always comply with this requirement IHI have developed a three-dimensional measuring and analysis system "MONMOS".  The system indicates immediately the deviation between the measured block shape and objective shape on a CRT display on a personal computer at the construction site.]]></description>

      <title>INFORMATION ACQUISITION SYSTEM AT FABRICATION STAGE BASED ON PRODUCT DEFINITION SYSTEM - COMPUTER AIDED INFORMATION ACQUISITION SYSTEM OF DESIGN AND MANUFACTURING IN SHIPBUILDING (PART 2)</title>
      <link>https://trid.trb.org/View/440604</link>
      <description><![CDATA[The need for Computer Integrated Manufacturing systems (CIM) is recognised in Japanese shipyards.  In a previous paper (see abstract no 90051071) a shipbuilding definition system was discussed and a System of Design and Assembling for Shipbuilding (SODAS) was proposed.  In SODAS, there are systems which include ship design, a system for cutting the designed ship structure into pieces and a system of assembling those pieces to a ship block.  The aim of this paper is to refine the assembling system in SODAS.  Two models are introduced here; one a facility model such as a crane, a lift-magnet and welding machines, the other an operation model in which operation data such as welding condition, and root gap should be managed.  An object oriented language on an engineering work station is also used to represent a ship and a shipyard model.]]></description>

      <title>THE PRODUCT DEFINITION SYSTEM FOR OIL-TANKER - COMPUTER AIDED INFORMATION ACQUISITION SYSTEM OF DESIGN AND MANUFACTURING IN SHIPBUILDING (PART 3)</title>
      <link>https://trid.trb.org/View/441054</link>
      <description><![CDATA[In order to integrate information in the design and manufacturing stage, System of Design and Assembling for Shipbuilding (SODAS) was developed.  This was discussed in a previous report (see abstract no 90051071), focusing on the design of bulk-carriers on the "UNIT" concept.  In a second report (see abstract no 92051025) the activity model and facility model in the assembling stage are introduced.  It was shown that design of the element parts can be easily carried out using the hull structure information obtained in the first report.  In this paper, the design of an oil-tanker model is discussed.  First, it is shown that oil-tanker structures can be parametrically designed using "plane type of UNIT".  It is also shown that it is very important to combine "box type of UNIT" for bulk-carriers and "plane type of UNIT" for oil-tankers in order to make a ship model for any kind of ship.]]></description>

      <title>A DISTRIBUTED PROBLEM SOLVING BASED MODEL FOR SHIPYARD SCHEDULING</title>
      <link>https://trid.trb.org/View/443360</link>
      <description><![CDATA[In this paper, a distributed architecture for scheduling in a shipyard is presented.  The architecture adopts an agent-oriented approach with site agents responsible for the scheduling of work areas.  The site agents carry out local scheduling and through negotiation with other site agents co-operatively perform global scheduling.  Scheduling is viewed as being two-tiered, with the first level involving the assignment of manufacturing work areas and the second being the determination of local resources such as workers and portable equipment which may possibly be shared among a number of work areas.  Due to the distributed nature of the architecture and its inherent flexibility, the model of the physical shipyard (e.g. machines, workers, and work areas) may be easily changed during the scheduling process to reflect actual changes which may occur in the yard.]]></description>

      <title>ACCURACY CONTROL TECHNIQUES FOR SUCCESSFUL SHIPBUILDERS AND SHIP REPAIRERS</title>
      <link>https://trid.trb.org/View/445145</link>
      <description><![CDATA[Accuracy control is a system that regulates the accuracy of a product as it is being assembled.  The system is based on measuring manufacturing processes and statistically analysing the results.  The results can then be used to predict the final accuracy of a product, as well as identify the work processes that contribute most to the amount of variation in achieving that final accuracy.  By adopting this system, the shipbuilder or ship repairer minimised the amount of rework required, particularly at the final erection stage. Accuracy control is also a very useful management tool, as it measures the productivity of the work processes used.  Accuracy control, is not a new concept, Japanese shipbuilders have been reporting significant advances in the quality of hull construction as a result of statistical control of production since the late 1960's.  There are two aims of this paper.  The first is to describe the basic principles of accuracy control.  The second aim is to analysis in detail three advanced measurement systems that can be used to measure assembly dimensions.]]></description>

      <title>FINNISH LASERS IMPROVE SHIPBUILDING EFFICIENCY</title>
      <link>https://trid.trb.org/View/445818</link>
      <description><![CDATA[Research has been carried out in Finland to develop technology and provide an accurate 3D co-ordinate-based dimensional control system that would reveal the deficiencies in production processes. From this research programme emerged a range of robust practical solutions called ACMAN (Accuracy Control MANagement).  The measurement of 3D co-ordinate values of any selected point on a surface is defined by a radial distance and two angles.  To make these measurements, ACMAN 3D co-ordinate meters use advanced optical laser technology.  From one position, distance is measured by the time taken for a short laser pulse to reach the target point and return to the receiver in the instrument.  This new measuring technology provides benefits to the user as measurements can be taken without artificial point targeting and are easy and fast to perform by a single operator.  The largest block assemblies can be efficiently and accurately measured to within 1mm.]]></description>

      <title>A CALCULATION METHOD OF FORCES AND MOMENTS ACTING UPON THE JOINT PART OF A FLOATING STRUCTURE ASSEMBLED ON SEA</title>
      <link>https://trid.trb.org/View/396959</link>
      <description><![CDATA[A method of constructing huge offshore structures is proposed. It involves the assembly and jointing at sea of several unit structures pre-constructed on land. The work must be carried out under the influence of wave, winds and current, making the investigation of the wave-induced vertical bending moment of the jointed part of such a structure very important at the design stage. This article presents a method for calculating the forces at work on this jointed part.]]></description>
