- Downward drilling force
- Hinge force
- Wind force
Each step has been done sequentially on this bolted-rig to consider the stress carefully.
Modal analysis was also performed to check the natural frequencies of the structure. Each element were modeled with beam188 and the joint connections were MPC184.
Stress analyses due to several boundary conditions have been performed on an oil digging rig to evaluate the effects of operational forces on the rig structure.
