Bastion was contracted to model and analyze three new truss joint configurations for a new semi-submersible deepwater drill rig. The idea behind the truss designs are to have less tubular connections to support the entire deck load thus decreasing the weight and making it easier to inspect.

Bastion structural analysts built three different bar to beam element models and ran over 700 load cases per joint. All models were built using FEMAP and calculated with Nastran solver. All supporting structural analysis was performed ABS code requirements.
