NOV 18-15M NXT Ram BOP 11003908-001 manual
BOP Configuration
The 18¾-15M NXT Double ram BOP is configured with an 18¾”-15,000 psi API studded top and flanged bottom, with six 3 1/16”-15,000 psi side outlets, and is equipped with doors utilizing pipe rams (various sizes), hydraulic ram operators with automatic locking, and XT™ door locking system (see Figure 2-1 on page 2-2).
Single, double and triple ram BOPs use ram blocks with rubber face seals to close around or shear and seal the drill string. When the rams are closed, the ram blocks slide on skid plates in the BOP cavity. Wellbore pressure pushes the ram block assemblies upward, and a seal is effected between the ram block rubber top seal and the seal seat insert. Ram block lateral side movement is guided by the cavity side pads (see Figure 2-2).
The UltraLock II (B) operators are used to close the ram assemblies on drill pipe and close off the wellbore pressure. The 14” UltraLock II (B) operators require a hydraulic pressure of 1,500 psi (103 bar) to accomplish sealing the wellbore pressure to the rated working pressure of the preventers. The 14” UltraLock II (B) operators are located on either side of the NXT body (see Figure 2-1 on page 2-2). When the rams are hydraulically closed, the
UltraLock II (B) operators automatically lock the rams in the closed position, and require opening hydraulic pressure to open them. The UltraLock II (B) operator is a multi-locking device, making it ideal for closing on variable ram assemblies.Although 1,500 psi (103 bar) hydraulic closing pressure is all that is required to seal off the wellbore to the rated working pressure of the preventers, the UltraLock II (B) hydraulic closing pressure, at the owner’s discretion, may be increased to a maximum of 3,000 psi (304 bar), if necessary
This locking system has been designed to increase the capabilities of Shaffer blowout preventers by providing a low maintenance and adjustment-free locking system while maintaining compatibility with all pipe ram assemblies that the BOP can accommodate.
The UltraLock II (B) locking system will lock on any pipe size within the range of the pipe ram assembly being used. Blowout preventers that are equipped with the UltraLock II (B) locking system are locked automatically in the closed position each time the piston assembly is closed. The preventer will also remain locked in the closed position, even if closing hydraulic pressure is lost or removed. Note that hydraulic opening pressure is required to unlock and reopen
the preventer.
