2.8. Offshore Drilling Rigs
The rig is the mechanical equipment for drilling oil and gas wells with a power-driven, lifting, rotating, drilling fluid circulation system and other auxiliary operations. For offshore drilling mechanical equipment, the structure, design calculations, and use of the equipment is essentially the same as for land. Therefore, there's no need to elaborate on these factors here. Here, we only do a brief introduction to the special problems of the offshore drilling rig.
2.8.1. Special Requirements of the Offshore Drilling Rig
When designing or selecting an offshore drilling rig and taking into account ease of use, the special requirements of the offshore drilling rig are summarized in the following
