Subsea Tee Design Optimisation

The FEA team were asked to perform an FE analysis of a high pressure pipeline tee in accordance with DNV OS-F101 which demanded careful mesh distribution with no tetrahedral elements. The project included design optimisation of the internal and external blend radii to eliminate any stress concentrations.

External pressure and fluid drag from currents and wave action were also applied to the connecting pipeline to establish the extreme operational conditions.

The project was completed successfully and on time and the success of achieving the tight timescales provided by the customer resulted in a good client/relationship motivating the customer to award our engineers with further projects.
