The world of BOPs – while it does experience change – does not do so as rapidly as some technologies. This is probably because it is such an essential piece of equipment in the drilling process that experimentation is cautious and incremental. So, while size and weight reductions and improvements in materials continue, BOP design is still based on the fundamental principles of the original ram-type BOP. Presented here are the latest offerings from BOP makers Hydril, Varco, and Cameron.
Varco and Hydril have recently introduced new versions that emphasize speed and ease of ram inspection and change-out. Whatever the cost for retrofitting an existing rig, it's more likely that new designs will be more economical in newbuilds, where the cost of installing the new technology would not likely add all that much to the daily rate.
