Genauigkeit (GSD Marking Triangles)

One of the major shipyard requirements is to reduce the need for additional fitting in the assembly process and thus reduce the production time. One way of doing this is to increase the accuracy in the assembly process, preferably at each step so that the accumulated errors are reduced. An important means to facilitate improved accuracy in both fabrication and assembly is the use of assembly is the use of assembly triangles (GSD Marking Triangles). These are used mainly for alignment in the assembly process, but may sometimes be used also for checking of accuracy after assembly.

The option is an integrated part of the software for marking of hull parts. Profile marking of GSD Marking Triangles is only handled in the Profile Cutting Interface. customization and control of the marking of GSD Marking Triangles is done via logical variables specific to this option. GSD Marking Triangles may be generated both for plates and for profiles and both for parts from the internal structure and parts related to the shell structure. GSD Marking Triangles are possible to mark in the following positions:

• at plate corners

• along profile traces

• along traces of abutting panels.

• along bracket traces

• along ship centerline

• along shell boundary

• at profile ends

• at manually defined positions on plane plate parts

• along the nominal plate edge on developed shell plates

In cases where both the GSD Marking Triangles and the marking trace are available for a marked item, the Nesting System will automatically combine them into one geometry with only one marking start necessary.
