Integrated Approval System For Penetrations of Pipe Through Structural Parts
After modelling the 3D Structural and Piping model of the ship, the
Penetrations module in the ShipConstructor suite provides a full
approval mechanism starting with
the proposal of placing a penetration, through sign-off by the
specialist, to the final implementation. It comes with numerous control
functions such as:
- User Permissions
- Standardization
- Approval Process
- Revision History
User Permissions:
Each user working on a project receives permissions assigned by the
project manager, preventing users from working on the product model
outside their expertise.
Standardization:
Penetrations are defined in the catalog, assigned to pipe sizes and grouped into specs.
Approval Process:
The process is database controlled and enforces all parties to do
their job at specific times. A revision log is generated automatically.
Revision History:
Penetrations may be changed after approval, which starts the approval process over again.
Case Study
How does it work and why do I need Penetrations manager?
The piping department routes pipe for a specific
system, using structural, outfitting and other drawings in the area of
his interest as a background. Penetrations may be detected through
plain visual inspection or using the built-in sophisticated
interference function. The piping detailer selects a pre-defined
penetration package associated with the system-spec from the piping
catalogue. During this process the penetration object is created in the
product model drawing and a related penetration record is created in
the database. Both items remain linked at all times. At this point the
status of the penetration is set to ‘Pending Approval’.
Now the penetration control department checks the penetrations,
modifies as required and sets the status to ‘Approved’. Other options
allow the penetration to be rejected, or returned to the piping
department for modification.
It is usually the structural department that finally implements the
hole into the structure. This is not the end of the story as often
requirements change and the process may have to start all over again.
All the while, the database keeps an automatic revision log of all
modifications, recording the user, action, date, time and reason.
The penetration approval process is fully integrated into the
ShipConstructor product model, and includes notifying the
NC-department, if a part requires re-nesting due to a penetration
change.
