 Outfitting: One-way interface from AVEVA Marine to other CAD system
Other CAD SYSTEM

9. In recent years, some troubles in production process have
occurred due to “insufficient production planning”.
We needs to improve production planning
 to start as early as possible
 to be more accurate information
JMU’s Objectives (1) problem to be solved

10. Purpose of production planning
 man-hour estimation
 cost estimation
 process planning
 finding bottlenecks on manufacturing process
JMU’s Objectives (2) about production planning
Reasons for “insufficient production planning” …
 necessary information could not be provided enough in time
 accuracy of information, especially welding length, is not good
Necessary information for production planning
 shape / size of hull block
 weight of hull block
 numbers of parts
 paint area
 cutting length
 welding length … and so on

Utilization of 3D-model in JMU (3)

19. 3D-model is created by using AVEVA Marine in basic design stage.
We call the model “basic design model.”
3D-model is utilized for production planning.
Key points are :
- enough accuracy for the necessary information
- when to provide the information
Recently JMU has been achieved early start of production planning,
and been seeing improvement in production process.
Summary of current situation in JMU

20. Current and Future issues (1)
 prepare the 3D-model even earlier
 Increase the accuracy of the 3D-model
Improvement in progress
JMU needs to enhance functions of AVEVA Marine by customization.
Three examples will be shown here.
1. Landing Helper
2. Scheme Filter
3. Easy Bracket

21.  JMU enhanced functions for shell stiffener landing.
 Previously JMU has been preferred interactive method to batch method.
 Because the flow of stiffener landing in AVEVA Marine is similar with
a process of basic designer’s thinking.
 However, JMU needs to define stiffener landing more effectively.
Customization Example (1) Landing Helper

Current and Future issues (2)

22. Customization Example (2) Scheme Filter
 JMU enhanced scheme function.
 For modification of 3D-model, scheme function is very useful.
 In order to shorten modeling period, JMU needs more powerful function
for updating model information, especially scantling.
 Because first input scantling is always initial or tentative information.
 For example, in one project, JMU needs update more than 50,000 structural members.

Current and Future issues (3)

23. Customization Example (3) Easy Bracket
 JMU enhanced function for definition of brackets.
 For basic designers, bracket definition in AVEVA Marine seems to be
the most time-consuming operation.
 In order to shorten modeling period, JMU needs to improve “bracket definition.”

Current and Future issues (4)

24. Conclusion
 Early provided 3D-model
- improved production planning
- first step of “Front End Loading”
- possibilities for future improvements in manufacturing
 AVEVA Hull Structural Design
- support enough details
- suitable workflow for basic designers
- customizable for improved productivity
We will continue!
