BOP

• The BOP attaches to the wellhead
• Onshore – located below the rig floor in the cellar
• Offshore (bottom supported drilling unit) – below the rig
• floor on the Texas deck
• Offshore (floating drilling unit) – on the seabed
• It is attached to the wellhead using flanged or collet
• connectors
• Normally installed after setting the surface casing string

Features:

• Seal Element molded with two different styles of inserts to reduce closing volume and increase closing cycles.
• Replacement wear place that eliminates metal to metal contact between the seal element inserts and BOP head.
• A piston design that provides complete balance more reliable operation and ease of assembly.
• A latched head for fast, easy access to the seal element and wear seals.
• An opening chamber head that prevents debris from falling into the chambers when replacing the seal element.
• A bolted inner sleeve that eliminates the need for repair and is field replaceable.
