Abstract:
Oilfield offshore and onshore drilling rig structures are center part of oil and gas exploration because the rig derrick and mast structures are essential piece of equipment for both onshore and offshore drilling, completion, and services. Different types of offshore and onshore rig derrick and mast structures have reviewed briefly. The major differences and similarities are also discussed. Different types of onshore land drilling rig structures along with design codes and standards are reviewed with more details. Then, the land rig mast structure design base, detailed engineering calculations, and finite element analysis-FEA are addressed based upon the code, standard, and engineering literature. Finally, the onshore design challenges, manufacturing recommendations, future innovative approaches and expectations, and some conclusions are presented.
