MSC Software Technology Tradition in Shipbuilding

Sesam Patran-Pre from DNV is developed by MSC UK and sold by DNV

Tribon Access is a toolkit in Patran as an interface with AVEVA’s Tribon CAD system. It is developed and sold by MSC UK.

NAPA (Finnish ship design software) is providing an interface with Patran/Nastran based on Patran PCL.

Lloyds Register was a pioneer with MSC Nastran and more recently MSC UK developed a panel buckling t lkit i P t f th

toolkit in Patran for them.

The Simulation Process- How often do we …

• Try to find a model or analysis from a program we worked on a couple years ago?

• Takes too long to find it• Can find results but not the model or assumptionsCan find results but not the model or assumptions• Can’t find it at all• The person left the company or moved to another program

• Give someone the wrong model to start their analysis?

• Want to pass on the experience and best practices of senior analysts to younger engineers?

Ship System Scenario

• AEGIS Missile Guidance Program has a request for re-work on the Digital Processing Board (DPU) tied g g ( )to the MK 99 Fire Control System RFA Driver Box.

• Customer requested that work needs to be qcompleted in a very short time (less than 1 week).

MSC Software Technology For Shipbuilders8

As a Manager – Where do you Go?• AEGIS Program started by NAVSEA in 1977 32 years

ago.

• Started at Raytheon 30 years ago.• Lot’s of employees, contractors, &

subcontractors involved

• Where do you start?• Can we use an older analysis?• Where is the analysis?• Where is the analysis?• Who did the analysis?• What process was used?• Was analysis is needed to be repeated?• What assumptions were used?
