7.0 Scope
This technical proposal provides a description of the 170k 2-leg snubbing unit that is truck mounted. It is designed for use in a variety of operations utilizing a crane or workover rig to rig up/down. The model described within this proposal is designed and built to the highest standards. This snubbing unit is completely assembled, cleaned, inspected and tested following this specification.

8.0 Snubbing Jack
This jack assembly is designed to push (snub) and pull (lift) pipe into and out of a dead/pressurized wellhead utilizing three (3) hydraulically operated 170k, 7-1/16” slip bowls. This assembly is designed to be used as both a Stand-Alone snubbing unit, and a Rig Assist snubbing unit. This assembly is designed to work in conjunction with the Annular BOP and 2 x BOP stripping rams. This assembly will consist of the following components:

- Jack Plate
- Passive Rotary
- Traveling Snubbing Slip Bowls
- Control Panel(s)
- Upper Work Platform
- Stationary Snubbing Slip Bowls
- Stationary Heavy Slip Bowls
- Jack Cylinders
- Annular Preventor
- Upper stripping Ram
- Bleed off/ Equalize Spool
- Bleed off/Equalize Plug Valves (1” ID)
- Lower Stripping Ram BOP

8.1 Jack base
50. This assembly is designed so that the Annular can be split for changing elements in the Annular.
51. This assembly will be the main support structure for the hydraulic cylinders, workbasket, Annular BOP and Stationary Snubbing Slip bowl.
52. The jack base will have one (1) manually extendable ladder assembly

8.2 Passive Rotary System
53. The primary design of the rotary is to allow the snubbing unit to perform drilling/milling operations in both snub/lift situations. This Passive Rotary system works in conjunction with a power swivel if required.
54. All hydraulic hose connections are integrated quick disconnector type.
55. The passive rotary allows the unit the ability to set tools requiring rotation in pipe heavy or pipe light mode.

8.3 Jack Cylinders
56. The two (2) jack cylinders will be custom made and have a 6” (15.24cm) bore x 4” (10.16cm) rod x 10’ (3.05m) stroke.
57. The cylinders can produce a combined push (snub) force of 85,500 lbs. (38,555 kg.) and a combined pull (lift) force of 170,000 lbs. (77,110 kg.) These assemblies will be mounted to the jack base assembly.
58. Anti-wear bands on packing glands and pistons.
59. 3,000 Psi maximum working pressure
60. Hydraulic braking system for both lift and snub.

8.4 Jack cylinder control valve
61. This valve assembly will consist of a “Husco” 6400 pilot operated split spool control valve which controls the up and down motion of the jack cylinders.
This valve will be plumbed to include a high speed (regen)/low speed circuit on the up stroke of the jack cylinders. This allows the operator to run the jack cylinders at a higher speed on the up stroke. The regen selector will be in the workbasket under the operator’s console.
62. The hydraulic flow lines from the Husco valve to the jack cylinders will be steel piping. All other hydraulic flow lines on the snubbing jack assembly will be hydraulic hoses.
63. Counterbalance valves in up and down control circuits to control over running loads.
64. The split spool valve assembly will be mounted to the jack base assembly.
65. The “Husco” 5000 A62 pilot operated control valve will be mounted in the operator panel.

8.5 2-1/2-Gallon Annular BOP Accumulator (Surge bottle)
66. The purpose of this assembly is to prevent overpressure of the Annular BOP control circuit. The nitrogen charged accumulator will compress when an upset on a pipe joint passes through the Annular BOP. Assembly mounts on the jack base.
8.6 Slip bowls
