Enerdrill Ground Pressure: This was an unusual job as the client wasn’t sure where to go for help. The gas drilling company, Enerdrill, were taking their rigs to a new site and were required to present calculations to show the pressure that the rigs would apply to the ground for safety reasons. I used the equipment weights and operating loads and SpaceGass (structural analysis program) to determine at what points on the ground the loads would be applied. I then used Inducta (another structural analysis program) to model a slab on the ground to determine the bearing pressure. Enerdrill were thrilled with the structural calculations and I enjoyed the challenge!
