The SS-15 BigBore II-H Subsea Wellhead System is Dril-Quip’s next generation wellhead
system designed for deepwater, deep well
applications. The BigBore II-H System features higher load carrying capacity and higher
temperature ratings. It has been designed to
facilitate the drilling of wells that penetrate
shallow water flow zones and require several
casing strings to accommodate small pore
pressure/fracture-gradient differentials.
The BigBore II-H Subsea Wellhead System
allows an additional 18" casing string,
hanger and seal assembly to pass through
the 18 ¾" wellhead with the BOP stack and
riser in place. This accommodates drilling and
running a large bore diameter casing string
through shallow pressurized water sands
with complete BOP control and with drilling
returns back to the drilling vessel.

The mechanical advantage of the
system is such that for 175,000
lbs of drill pipe overpull at the
wellhead, a preload of 2,000,000
lbs is created between the
low-pressure and high-pressure wellhead housings.
After lockdown, the tool is stroked down to the start
position and jayed back to the right. Cementing
operations can commence at this time.
Once cementing is complete, the tool is rotated to the
right five turns to release from the wellhead and the
Rigid Lockdown Tool is retrieved with a straight pull.

Wear Sleeves and Wear Bushings
Wear Sleeves and Wear Bushings protect the bore sealing areas in the 18¾" wellhead for each phase of the drilling
operation. The BigBore II-H Wear Sleeves and Wear Bushings are installed when the bottom hole assembly is run,
eliminating the need for an extra trip. The Wear Sleeve is a bore protector that is carried to the wellhead on a bit
sub and is installed just above the bottom hole assembly. It is always retrieved when the bottom hole assembly
is retrieved. The Selectable Wear Bushing is a bore protector that is run on a bit sub with adapter sleeve above
the bottom hole assembly. The Selectable Wear
Bushing may be retrieved with the bottom hole

after removal of the Nominal Bore
Protector. The seal element activator
sleeve can only be released when
the split release ring engages the
minimum ID in the wellhead or
wear bushing.
Dril-Quip’s Special BOP Test Tool allows
testing of the BOP stack with the Nominal Bore
Protector installed.
Features
• Allows pressure testing on top of the Nominal Bore Protector without transferring load
to the top of the Protector
• Seal activation mechanism does not allow
premature activation of seal element
• Alternative BOP Test Tool capable of running and installing Nominal Bore Protector
and test in one trip
BOP Isolation

Features
• Allows for BOP Tests when
Nominal Bore Protector is
removed (requires BigBore II
Wellhead Housing Adapter,
as shown)
• Tests on wear bushings (after
Wellhead Housing Adapter
is removed)
• Alternative BOP Test Tool capable of landing on wear sleeves
Special BOP Test

Special BOP
Test Tool
on the
Wear Sleeve
• Tests BOP while isolating casing
hanger and seal assembly from
test pressure
• Can be landed on top of casing
hanger with wear bushing
removed (seal assembly is
isolated from test pressure)
• Seal activation mechanism does
not allow premature activation of
seal element
• Through-bore tool eliminates
possibility of over-pressuring
casing
• Ample flow-by area facilitates
running and prevents swabbing
when tool is retrieved
• 4 ½" API IF box up and 4 ½" API
IF pin down

18 ¾" Lockdown Sleeve
The Lockdown Sleeve lands on the production casing
hanger and locks the casing hanger and seal assembly
to the wellhead housing. This prevents cyclic movement of casing hanger and seal assembly from thermal
pipe expansion and annulus pressure build-up.
Features
• Profile on upper end of the Lockdown Sleeve is used
for attachment of the running tool
• Lockdown mechanism on upper OD of Lockdown
Sleeve is activated by the running tool
• Lockdown mechanism is adjustable based on the
reading obtained by the lead impression tool
and can accommodate a casing hanger landing
up to 3/8" high
Lockdown
Sleeve
Running
Tool
• Lockdown function operates via actuation sleeve
that drives out a lockdown ring into the lockdown
groove profile in the 18¾" wellhead housing
• Metal-to-metal seal on lower end of Lockdown
Sleeve is mechanically trapped in place and is
used to seal off the upper bore of the uppermost
casing hanger
• Seal has been successfully tested to 15,000 psi with
gas per API 6A PR-2 requirements with zero leakage
at 300º F
Lockdown
Sleeve
• Lockdown Sleeve’s upper ID seal surface is lined
with Alloy 625 for corrosion resistance
• Lockdown Sleeve interfaces with the subsea tree’s
stab sub to isolate the VX cavity and production
hanger pack-off
• Lockdown capacity – 3.2 million lbs
Lockdown Sleeve Seat Protector
The Lockdown Sleeve Seat Protector is
a wear bushing device used to prevent
damage to the seal area and lockdown
mechanism of the lockdown sleeve.
• Run and retrieved with the 18¾"
Multi-Purpose Tool and lockdown
Sleeve Seat Protector running/
retrieving adapter
Seal
Assembly
• Seat Protector’s minimum ID
matches the minimum ID of the
Lockdown Sleeve
• Upper funnel allows for easy guidance of downhole tools.

The LS-15 Liner Hanger System
features field-proven technology that
incorporates the following:
Profile for Locking
Cement Bushing (LCB)
• High strength, high pressure, high
load-carrying capacity
• Metal-to-metal annulus packer seal
for high pressure service
• No hydraulic or mechanical devices
on the hanger body, minimizing
leak paths
Body Lock Ring
One-Piece C-Ring
Hold-Down Slip
(Optional)
• Large slip area and controlled
friction minimizes stress in the
supporting casing
• All hangers are automatically centralized when
C-ring slip is set
• Bypass flow area is the same after setting the liner
hanger slip as in the running position
• Maximizes circulating flow-by areas for efficient
cementing operations
• The LS-15 Liner Hanger System can be sized
and configured to customer specifications

• Standard service for many sizes is 10,000 psi at 400° F.
Higher pressures are achievable and are only limited by the
capacity of the packer mandrel and casing
Rotational Option
With the addition of a rotating bearing assembly, the LS-15
Liner Hanger can be rotated with the slips in the set position
during the cementing operation. This feature can assist in
completing a successful cement job.

The LS-15 System Incorporates
a Unique Hanger Slip Design
Dril-Quip’s proprietary one-piece C-Ring HangOff Slip has been developed to greatly reduce
the amount of hoop stress placed on
the supporting casing by the liner load.
Dril-Quip’s circumferential slip design
distributes the liner load much more evenly
around the casing than conventional multislip segment hanger systems. The C-Ring Slip
also incorporates a method of controlling the
friction between the slip and the hanger body.
One-Piece C-Ring Slip
This “controlled friction” design redirects
hoop load into axial load, drastically reducing the
collapsing load on the hanger body and burst pressure on the casing.
This combination of stress loading permits the LS-15 Liner Hanger
System to hang longer and much heavier liners than possible with
conventional technology.

The liner hanger is run to total
depth with the slip in the

When released from its locked-down
running-in position, the slip will spring
open and come into contact with the ID
of the supporting casing.

Casing
The hanger body is then slacked off
onto the slip. The sharp teeth on the
slip will secure the liner hanger to the
supporting casing. At light loading, the
dull inner slip teeth will not yet grab
the cone as it slides behind the slip.
Hanger
Cone
Casing
As the loading increases and travel progresses, the inner teeth begin to form small
shoulders on the liner hanger slip cone. As
the shoulders increase in size, the downward
travel of the liner hanger is stopped before
loading gets high enough to collapse the liner
hanger body or burst the supporting casing.

LS-15 Running Tool
• The system incorporates high torque capacity for drilldown, wash-down applications and rotation during
cementing operations
• The Running Tool incorporates a port isolation system that
eliminates the possibility of prematurely setting the slip,
or releasing from the hanger while running into the hole

Connection
• The hydraulics to set the liner hanger slip are built into the
Running Tool, not as part of the hanger system, eliminating the need for a hydraulic port through the body of the
liner hanger
• The Running Tool is hydraulically released from the liner
hanger and also incorporates a unique right-hand hydromechanical secondary release
Running Procedures
In order to solve many of the problems encountered during
liner installation, Dril-Quip has simplified the running procedures of the liner hanger for exceptional ease of use.

ril-Quip’s
Cementing Manifold is designed
with a unique head that contains four
pockets at circumferentially placed locations. This
arrangement eliminates stacked-plug launching
heads and their corresponding height requirements, allowing for a more compact design. The
operator can load releasing balls and pump-down
plugs in three of the four pockets easily on the
rig floor. The manifold eliminates the need to
break any connections when loading and launching releasing balls or
pump-down plugs. The
manifold allows circulating the hole through the
fourth bypass pocket
located in the head.
Dril-Quip’s Cementing
Manifold can be made
up in the string prior to
running the liner hanger
for ease of operations,
and can accommodate
rotational torque so that
drilling the liner hanger into position, if required,
is not a problem.
