Lockdown Sleeve 36" Wellhead Housing
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.
Features • Wellhead housing designed for 15,000 psi and 8.8 million lbs of end-load carrying capacity at the bottom internal landing/load shoulder profile

Conductor Wellhead Systems 36" Conductor Wellhead and Running Tools The 36" Conductor Wellhead is the starting point for the primary conductor string. It has a prep on the ID for the 18 ¾" Subsea Wellhead. • Internal profile provides locking groove to lock and preload 18 ¾" Wellhead to 36" Conductor Wellhead • Handled with, and can be run with, the Conductor Wellhead Running Tool • Run with Cam-Actuated Dril-Ahead (CADA) Running Tool Dril-Quip’s standard Conductor Wellhead Running Tool is primarily used as a handling tool for the 36" housing joint. • Anti-rotation pins mate with slots in conductor housing, ensuring running tool does not rotate within conductor housing • Cam-actuated lock/unlock mechanism releases running tool from housing via right-hand rotation of drill string and locks running tool with left rotation
• Lock/unlock indicator provides visual confirmation of tool status • Tool has removable plugs on top; the tool can be used to install the 36" string Dril-Quip’s Cam-Actuated Dril-Ahead (CADA) Tool incorporates the same design features as the standard Conductor Running Tool. • CADA Running Tool allows drilling ahead using detachable mandrel integral to the CADA Tool • J-lug sleeve allows CADA Tool’s inner mandrel to be detached or “jayed” out of sleeve so the 26" hole can be drilled without recovery of CADA Tool • Shear pins trap CADA Tool to 36" Conductor Wellhead during the drill-ahead operation

28" Supplemental Casing Hanger System Dril-Quip’s 28" Supplemental Casing Hanger System provides a method to install a secondary conductor string inside an adapter integral to the primary conductor below the wellhead. The 28" Supplemental Casing Hanger System provides an annulus access and ROV monitoring system. Dril-Quip’s 36" x 28" Supplemental Adapter assembly provides a positive stop landing shoulder for the 28" Casing Hanger. • Load shoulder in Adapter ID captures split lock ring on the Casing Hanger for a positive lock between the two components • 4" ports and annulus venting valves provide annulus access to the 28" and 22" annuli
• Flat faces and tapped holes on Adapter OD for slope indicator’s mounting brackets • There is a sealing area on the ID of the adapter for the 28" supplemental casing hanger • Available in a variety of sizes The 28" Casing Hanger Running Tool runs and lands the 28" Casing Hanger into the 36" x 28" Supplemental Adapter. • Cam-Actuated Running Tool for easy right-hand rotation release • Two methods for filling casing are: ball valve arrangement or auto-fill check valves that allow sea water to fill the casing while running

18 ¾" Wellhead System Running Tools Mechanical Rigid Lockdown Running Tool
18 ¾" Subsea Wellhead Running Tool Dril-Quip’s 18¾" Wellhead Running Tool has a left-hand make-up, right-hand release, cam-actuated locking design. An indicator rod is used to determine lock/unlock status. The running tool is unaffected by hydrostatic pressure and has ample exhaust and fill ports. The Wellhead Running Tool is used to handle the 18¾" wellhead and when running the wellhead with the Mechanical Rigid Lockdown Tool.
Indicator Plate
18 ¾" Mechanical Rigid Lockdown Running Tool The 18 ¾" Mechanical Rigid Lockdown Running Tool allows the running, installation and cementing of the 18 ¾" Rigid Lockdown Wellhead System and 22" casing on drill pipe in one trip.
Features • Operates in conjunction with the 18 ¾" Housing Running Tool and runs the 18 ¾" wellhead equipped with the rigid lockdown system
18 ¾" Standard Wellhead Running Tool
Actuating Sleeve
• Upward drill pipe pull functions master linkage to activate the rigid lockdown mechanism on the 18 ¾" wellhead • Lockdown is verified with position indicator plate on the OD of the outer sleeve • Drill pipe overpull at wellhead creates preload between conductor and 18 ¾" wellhead • Can create a preload up to 2 million lbs
18 ¾" Rigid Lockdown Wellhead
The mechanical advantage of the system is such that for 175,000 lbs of drill pipe pull 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 assembly or left in the wellhead. The illustrations below depict the Wear Sleeve and Selectable Wear Bushing assemblies in the wellhead for: 1. Drilling out for 18" Casing with the 18 ¾" x 17" Wear Sleeve 2.

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.
