PT&P custom designed and fabricated a 27′ x 16′ x 21′ structural frame to be placed on the sea-bed for an offshore rig. This assembly will be used as an undersea cable support frame, capable of withstanding a load of 600 Kilonewtons (68,000 lbs for each pad). It is constructed of 8 tube-steel, a 10 channel, and a steel plate. The frame will remain stationary on the sea-bed and is designed to endure heavy wave action when lowered to or raised from the sea-bed.

Finite element analysis of the lifting lug on the structure was performed to verify load conditions.  A trial fit-up of bolted sections was also conducted to ensure the structural frame will assemble easily before being placed in position.
