High-pressure annular BOP

DL BOP
The Cameron DL high-pressure annular BOP allows reliable performance in
a shorter height and lighter weight than comparable annular BOPs.
The unique design of the DL BOP does not require wellbore assist. The
annular can close on drillpipe or large tubulars without reducing operating
pressure, which minimizes risk of indention or damage to casing.

Sizes: 7-1/16” to 21-¼”

■■

Working Pressures: 2,000 to 10,000 psi

■■

Dual configurations available for certain sizes

Each packer assembly has passed API 16A qualification testing
Packer with interlocking segments

Functionality
Closing pressure forces the operating piston and pusher plate upward to
displace the solid elastomer donut and force the packer to close inward.
As the packer closes, interlocking-steel reinforcing inserts rotate inward to
form a continuous support ring of steel at the top and bottom of the packer.
The inserts remain in contact with each other whether the packer is open,
closed on pipe, or closed on open hole.

DL BOP—dual configuration

 quick-release top with a one-piece split lock ring permits quick packer
A
changeout with no loose parts involved. The design also provides visual
indication of whether the top is locked or unlocked
Components subject to wear are field-replaceable and the entire
operating system may be removed in the field for immediate changeout,
without removing the BOP from the stack
Twin seals separated by a vented chamber positively isolate the BOP
operating system from wellbore pressure. High-strength polymer
bearing rings prevent metal-to-metal contact and reduce wear between
all moving parts of the operating system
 vailable with a three-inch gas bleed port that runs from the inner
A
diameter to the outer diameter
P ackers for DL BOPs have the capacity to strip pipe as well as close
and seal on any size object that fits in the wellbore. These packers will
also close and seal on open hole at half working pressure
S tripping packers are available and reference information is available
in TC9609 E-24
Popular sizes of the DL BOP are available with high-performance
CAMULAR* elastomer technology annular packer subassemblies
Manufactured to comply with NACE specification MR-01-75 for
H2S service
