9 SYSTEM DESCRIPTION CHAPTER 2: TOP DRIVE SYSTEM DESCRIPTION INTRODUCTION AND GENERAL SPECIFICATIONS The HMIS top drive is designed for use on small drilling rigs and workover rigs. The HMIS top drive is powered using an independent hydraulic power unit. To create the optimum power supply system required for each of its top drives, TESCO combines industry proven prime movers with its own series of hydraulic pump drives and filtration equipment. The HMIS top drive is powered using one of the following power unit configurations: 475 hp prime mover with a two-pump drive (Detroit Diesel Series 60)-most common 460 hp prime mover with a two-pump drive (Caterpillar 3406B) Metric unit conversions (in brackets) have been provided for convenience only. All product specifications use the original imperial units unless indicated otherwise. Note: All weight values are approximate.

12 TOP DRIVE SYSTEM DESCRIPTION SYSTEM DESCRIPTION Gearbox The gearbox couples one hydraulic motor to the gear train. The motor is a bi-directional hydraulic vane type, and it has pressure ratings of 4,000 psi (27.6 MPa) continuous and 4,500 psi (31.0 MPa) intermittent. The HMIS top drive system is configured with a standard gear ratio of 2.19:1. An optional 1.64:1 gear ratio is also available. The gearbox houses gear reduction and forced lubrication systems as required for the unit. The integral drive hub is internally splined to accept the integrated swivel and quill. Load Collar and Load Nut The load collar and load nut transfer loads from the elevator links to the quill. Mudsaver Valve The mudsaver valve is a double-ball crank valve that acts as a mudsaver. It replaces the upper and lower Kelly cock. The valve does not descend below the rotary table, except in emergency situations, and it is always easily accessible. The mudsaver valve actuator can be operated remotely from the driller s panel.! Caution: The actuated upper ball valve is not for well control; it functions solely as a mudsaver. The manual operating lower valve is for well control. Ensure that the valve selected can fit into the existing casing. Pipe Handling The pipe handling abilities of the HMIS include the following: Elevator Link Tilt Cylinders: These allow extension and retraction of the elevators 35 forward from the vertical position and 55 backward from the vertical position. Grabber (back-up wrench): The grabber acts as a back-up tong for making or breaking connections at any point in the mast. The grabber will accommodate tool joints from 2-3/8 in. to 5 in. OD. Counter-Balance The top drive features an automatic thread feed compensation for make up and break out operations. TESCO CORPORATION, TON HMIS 475HP REV 2 6

13 SYSTEM DESCRIPTION TOP DRIVE SYSTEM DESCRIPTION Swivel The HMIS top drive features a drilling swivel with an integrated one-piece quill. This configuration offers the following advantages: no connections from the swivel bearing to the top of the mudsaver valve increased reliability/reduced maintenance decrease in the overall length and weight of the top drive readily available replacement parts Top Drive Power Supplies The top drive motor is powered by two axial piston pumps, which are located on the rear of the prime mover. All top drive robotic functions are powered by an auxiliary hydraulic system, which is located on the prime mover module. Handling Frame The top drive is shipped in its own handling frame. This frame allows you to transport and handle the top drive by using standard rig moving equipment. POWER UNIT The HMIS Top Drive power unit consists of the following: prime mover module, which includes the pump drive and filter manifold, the oil reservoir and cooling system, and the auxiliary system components hose storage reel Prime Mover The prime mover is a skid-mounted diesel engine (Detroit Diesel Series 60). Prime movers are equipped with a fuel day tank, an air starter, standard instrumentation packages, and appropriate safety and emergency shutoffs. Pump Drive and Filter Manifold The pump drive/filter manifold is skid-mounted and includes the following equipment: variable displacement, bi-directional axial piston pumps (two) flow meters and temperature gauges a series of hydraulic oil filters hot oil shuttle (to assist with oil cooling) auxiliary hydraulic pump and motor The auxiliary hydraulic equipment includes the following: a gear pump (2,000 psi, 7 gal/min; MPa, 26.5 liters/minute) 10 hp (7.46 kw) explosion-proof electric motor associated filters and controls REV 2 250TON HMIS 475HP TESCO CORPORATION,

14 TOP DRIVE SYSTEM DESCRIPTION SYSTEM DESCRIPTION Hydraulic Oil Reservoir/Cooler The hydraulic oil reservoir/cooler is skid-mounted and contains the hydraulic oil storage reservoir and cooling system components. All reservoirs are equipped with a level gauge, temperatures gauges, and return oil filters. Cooling System Components The cooling system components provide cooling for hydraulic oil used by the power and auxiliary hydraulics systems. An air/oil heat exchanger (controlled by a thermostat) cools the hydraulic oil before it is returned to the tank. Figure 2-2: HMIS power unit configuration 1.

15 SYSTEM DESCRIPTION TOP DRIVE SYSTEM DESCRIPTION TORQUE ARREST SYSTEM The torque arrest system is typically shipped in the second standard sea container. It consists of the following components: extend frame torque bushing extend arms extend hydraulic cylinders torque track T-bar torque beam, torque beam clamps, stabilization devices, and all required rig up items Extend Frame and Extend Arms The extend frame is pinned to the top drive. It allows you to extend the top drive away from the torque track. Torque Bushing The torque bushing is attached to the extend frame. Ultra High Molecular Weight (UHMW) inserts reduce friction as the top drive moves along the torque track. No lubrication is required. Torque Track The torque track, in conjunction with the torque beam and T-bar, transfers reactive torque to the lower section of the derrick and the substructure.the track is suspended from the crown by a cable hanging assembly, and is mounted with a simple clamp anchoring arrangement. Track components can be configured to fit most mast heights. Torque Beam, Torque Anchor and T-bar The torque beam is mounted on the rig, typically to the lowest strongback. It is then connected to the torque track via a T-bar. An offset torque anchor beam and post is available for use on service rigs. This torque anchoring system compensates for the 3.5 lean of the service rig mast REV 2 250TON HMIS 475HP TESCO CORPORATION,

17 SYSTEM DESCRIPTION TOP DRIVE SYSTEM DESCRIPTION SERVICE LOOP The hoses are spooled onto the hose reel prior to shipping. Power (Closed-Loop) Hydraulic Hoses two 225 ft. (68.58 m) x 1-1/2 in., 5,000 psi (34.5 MPa) hoses (one supply, one return); these supply closed-loop hydraulic oil from the pump drive module to the top drive motor Auxiliary Hydraulics one 225 ft. (68.58 m) x 3/4 in. R2, 2,000 psi (13.8 MPa) hydraulic hose; this supplies hydraulic oil from the pump drive module to the top drive robotics system Case Drain one 225 ft. (68.58 m) x 1-1/4 in. 1,625 psi (11.2 MPa) hydraulic hose; this returns auxiliary hydraulic oil and motor case drain flow from the top drive to the hydraulic oil reservoir Control Cables The 225 ft. control cable is spooled onto its own cable reel. The 160 ft. control cable remains attached to the main electrical panel on the power unit and hangs from a cable hook during storage. one 225 ft. (68.58 m) 37-conductor cable: this cable connects the driller's panel to the top drive one 160 ft. (48.77 m) 37-conductor cable: this cable connects the driller's panel to the main electrical panel on the power unit DRILLER S PANEL The driller s panel is a stainless steel enclosure that is mounted on the drill floor during installation procedures. It contains all controls, indicators, mounts, gauges and connectors required to operate the top drive. There is an optional air-purge system available for the driller s panel. All controls are electrically activated hydraulic (24 VDC) non-earth ground REV 2 250TON HMIS 475HP TESCO CORPORATION,
