Process Equipment Update
The data obtained had to be held securely under proper configuration control. This not only allowed the model users to determine the ‘build state’ but also ensured that changes made by suppliers could be incorporated. It also indicates whether the data are: specification values, from calculation or measured from test. The data must be transferred accurately and quickly to the
analysis in a method that avoids the possibility of transcription errors.
Integration with complex database The customer integrated Flowmaster into a complex database to provide the users with an integrated modelling environment tailored directly to their requirements. The database facility provides the ability to store and maintain all the data to aerospace configuration control standards. The database design eliminates data duplication. Finally, a ‘wizard’ was developed that transfers data from the database to Flowmaster eliminating the possibilities of data misuse and transcription errors.
Identifying system failures The UK’s Ministry of Defence (MoD) was experiencing multiple pump and pipe work failures within the sea water fire mains on two
vessels.These failures were attributed to various causes: very high cost of maintenance on pumps; frequent mechanical seal and motor bearing failures; inability to meet system design requirements. Various small targeted initiatives to try and improve system
performance were carried out, however it was recognised by the Marine Auxiliary Systems Integrated Project Team that a more joined up, system wide approach was required to address the route cause of the problems. Designed to mimic current onboard system management
software, a custom interface was developed in Microsoft Excel and fully integrated with Flowmaster, enabling service engineers to run simulations and view results through a familiar software environment. The integration of Babcock Marine’s user interface
enabled engineers to validate the system designs in Flowmaster quickly and
easily.To add clarity to the results, pressure readings were automatically extracted from the Flowmaster model at the actual positions of the onboard remote pressure indication. These readings were superimposed onto the model diagrammatic to give direct correlation with the readings visible on the onboard control programs.
The future Companies will continue to seek greater integration and customisation of all CAE tools and only by providing openness and interoperability will vendors be able to satisfy the market demands. By taking a system wide, integrated approach customised
for their specific users, customers will see real solutions to the industry challenges. n
