Section 2 Letourneau LDW 750K AC Draw works Item Qty Description 2.1 1 LDW 750K AC Draw works, Direct Gear Drive

For Use with Two (2) Letourneau Power Systems AC Motors

Hoisting Capacity: 750,000 lbs. on 12, 1-3/8” dia. drilling lines.

POWER: Two (2) each Letourneau TT1150 AC Vector Motors; Continuous rating of the motor is 1,500 HP and intermittent rating for draw works duty is 2,200 HP. Supply voltage: 575 VAC, 3 phase, 40 Hz base speed, 6 pole, max speed of 2300 rpm. Includes 20 HP, 460 V, 60 Hz, 3 Ph., 40oC ambient electric blower motor with filter and IP44 exhaust cover.

Main Drum: Bare tube is 27” dia. x 56-1/4” long; Lebus shell provides grooving for 1-3/8” Dia. wire line. The drill line clamp is located in the off-driller’s side drum flange. Rubber turn-back rollers are provided on each drum cover.

Braking System: The draw works is designed to raise, lower and hold the hook load with the electric drive motors. The motors provide sufficient torque capacity to control rated loads at rated speeds without overheating during normal pipe and casing handling operations. Friction disc brakes are supplied for emergency stopping should the motor power fail. The emergency brakes should not be used to stop or hold the load in normal operation. The disc brake system consists of two (2) heavy duty solid discs manufactured from abrasion resistant steel, securely attached to its hoisting drum flange with high strength steel bolts, and four (4) spring applied, air released brake calipers with two (2) calipers on each disc.

Air pressure of 105 psi is sufficient to completely release the calipers. Two calipers will hold the maximum rated load capability of the draw works. This provides a safety factor of 2 for the disc braking system. This safety factor is in line with the requirements of internationally known certification authorities.

Operating levers connect the actuator to the brake shoes. This separates the actuator from the heat of the disc and brake shoes. An adjustable clevis on the actuator adjusts the clearance between the disc and the brake shoes. Proper adjustment compensates for brake shoe wear and maintains the capability of the caliper.

The shoes are guided by sliding surfaces to ensure they do not drag when released. Centering bolts are used to equalize or shift the air gap. When set, the shoes freely float on guide pins to ensure equal lining wear.

The actuators and the levers are connected via a toggle link which compensates for reduced spring forces

Main Dynamic Braking is accomplished by the AC Motors through dynamic braking resistors powered through the AC Drive System.



Page 12 of 62

Emergency Braking is provided by caliper type disc brakes operating on two (2) air cooled discs. The brake discs are mounted on each end of the main drum. Four (4) caliper disc brakes are provided for emergency stopping, parking and holding of a suspended load. The calipers are spring applied and air released. The brake discs are air cooled and are not satisfactory for continuous dynamic duty. Brakes may be used as a crown and floor saver for emergency stopping during the hoisting and lowering operations. When the brakes are used for parking or suspending a load, the operator must assure that the air pressure in the calipers is reduced to zero (0) and the brakes are holding properly before removing power from the draw works motors. Emergency Lowering Controls: Manual release is provided for safety should the need arise to lower the load by manual methods. Manual release consists of an emergency air tank and manual pressure control valve which is mounted at the draw works. The emergency tank is charged from the main rig air system with protection to prevent loss of charge should the main system pressure fail. Motor Control and Energy Management System: To be provided by others. ENERGY MANAGEMENT SYSTEM is required to limit motor speed. Bearings: All bearings are spherical or cylindrical roller type. Lubrication: Drum shaft bearings are grease lubricated. The gearbox is lubricated with pressurized oil supplied by two (2) 10 HP, 460 volt, 3 phase, 60 Hz, electric motor driven gear pumps. One pump is the primary pump and the other pump is used as a backup. Water cooled lube oil heat exchanger mounted on main skid. Four (4) 1 KW, 460V, 3 phase immersion heaters mounted in gearbox sump to keep oil temperature at a minimum of 100oF. Draw works Frame and Skid: The draw works frame is constructed from fabricated steel plates. All bearings are mounted in bearing housings that are bolted to the main frame. Covers are provided over all rotating members. All draw works equipment is mounted on a single, heavy duty oilfield type skid. Lifting provisions, tailboard ends, are provided at each end of the skid Draw works Guards: Guards are provided around disc brakes to limit the amount of contamination of the discs and caliper assemblies. Drum Encoders: Two HS35 intrinsically safe encoders are included driven from output shaft of gearbox with additional room to mount 1 more HS35 encoder. Requires intrinsically safe barrier to be provided by control supplier. Design Temperature: Minimum design temperature is 32o F (0o C) per API 7K Paint: Draw works to be painted Le Tourneau Blue.

5 1 Electronic Mud Pump Pulsation Dampener and Pressure Control



Page 40 of 62

The Mud Pump Electronic Pulsation Controller module is a user friendly system that takes input from piston position sensors on each pump and calculates pump speed and phase difference between piston positions. With two (2) or three (3) Mud Pumps on line, the controller gives the same control input for the speed of the Mud Pumps until the speed reaches approximately 15% of the base speed. Then the module starts modulating the speed reference of the follower mud pumps to obtain synchronizing speed with the lead mu pump. At the same time, depending on a preset phase difference setting, it will provide a phase shift between the Mud Pump piston strokes; so that the overall effect will be like a single multi-piston Mud Pump. This will reduce the amount of ripple by at least 50% or more resulting in a greater continuous output pressure. The system also allows the Driller to set a pressure limit on the standpipe. If the pressure limit is reached, the system automatically throttles back the pumps to prevent the pop-off valve from opening.

The system consists of the following:

6 1 Electro-Driller System

“Electro-Drill” is the most advanced and Integrated Automatic Drilling & Traveling Block Safety System. It utilizes PLC and Touch screen Control Technology with software designed to optimize drilling control and drilling safety, complete with reliable sensors and control interfaces. Normal steady drilling functions carried out by the Driller can be performed by the “Electro-Drill” with far more precision, consistency, and safety, due to the fact that all related drilling variables are integrated and interacting simultaneously.

The “Electro-Drill” System can be installed on gear driven Draw works and provides three (3) important functions related to drill penetration & block movement: Auto driller, Kinetic Energy Monitoring & Crown Block/Floor saving.

Like all LeTourneau POWER SYSTEMS equipment, the “Electro-Drill” is designed with high technology hardware and software. The hardware is very powerful that it can cope with different rig types and operation environment, while the software and settings can be changed to meet present and future drilling needs.

AUTODRILLER FUNCTIONS



Page 41 of 62

The “Electro-Drill” is designed to ensure continuous drill penetration by automatically controlling the WOB (Weight On Bit) and/or ROP (Rate Of Penetration).

Interface with the Driller is via a color touchscreen LCD (display) and includes an intuitive, easy to use HMI (Human Machine Interface). All aspects of usage and configuration of the “Electro-Drill” can be carried out at the display, as well as calibration of the various sensor interfaces. The main mode of operation of the “Electro-Drill” is “ROP Mode” where it automatically controls the selected Target ROP to ensure continuous drilling penetration. In unconsolidated formations, a secondary mode of the “Electro-Drill”, “WOB Mode”, allows a maximum drill bit weight to be selected by the driller, and thus irrespective of ROP. In all operational modes a maximum ROP and WOB limit can be set, etc. in order to prevent damage to the well or the equipment.

Block movement, and thus ROP, is detected via a Draw works Mounted Encoder, and the Total Weight/WOB is obtained from the Weight Indicator system or the hook-load sensor.

The “Electro-Drill” can achieve a smooth drilling penetration rate by the control outputs to the VFD motors, according to the settings and the sensor feed-back.

An Emergency Stop Button on the panel will engage the brakes to full-on at any time. The Auto driller On/Off switch allows the driller to release the “Electro-Drill” momentarily from control of the draw works.

7 1 Kinetic Energy Monitoring Functions

The system continuously monitors the position, downward speed and weight hanging on the block, thus the block's Kinetic Energy, and by comparing this to the braking torque/force available will effectively act as a floor saver. The Electric brake is initially applied by the system if it fails to be brought in by the Driller, and secondarily the mechanical brake will be applied to automatically maintain a safe speed and stop the elevator above the drill floor.

8 1 Crown Block Saver Function

Through upward motion of the traveling block, the “Electro-Drill” continuously monitors the position and upward speed of the block and will apply the brakes automatically, thus always ensuring the traveling block does not collide with the crown. Much in the same way as the downwards motion Kinetic Energy functions does, the brake is initially applied by the system to slow the block before the coming to a complete stop. This ensures that the wire lines do not 'jump' the pulleys.

9 1 System Configuration

The “Electro-Drill” System is configured generally with the following components:

(1). Touchscreen Display & Control units. The HMIs are high-brightness touchscreens. Menu select multi-functions and multi-tasking Display & Control Panel. The Display Screen delivers both Auto Driller functions and Kinetic Energy/Floor & Crown Block Saver functions by selecting the



Page 42 of 62

appropriate menu. It is an intuitive and easy to use HMI (Human Machine Interface) Mimic with on-screen instructions, and enables the Driller or the technician to operate and configure the “Electro-Drill”, as well as to calibrate the various sensor interfaces.

(2). Control Electronics Unit. A PLC (Programmable Logic Controller) based unit which provides the interface to the brakes and the system sensors, and also the program for the entire system.

(3). Sensors and Control Interface package. Sensors for the “Electro-Drill” system consist of Block Position Sensors, Drum Movement Encoder, and Brake Pressure Sensor on the Draw works.

It is designed to omit any foaming or steam that can be generated by heat of the mud in the tank. It has a short antenna which emits short pulses. These pulses are reflected back & are received as echoes. It outputs a 4-20mA signal which makes it intrinsically safe. The calibration of the senor is accomplished using a handheld device which uses HART technology. One (1) Trip Tank Sensor: This type of sensor uses radar technology in either C (6GHz) or K (26GHz) band to continuously monitor levels of mud in the tanks. It is designed to omit any foaming or steam that can be generated by heat of the mud in the tank. It has a short antenna which emits short pulses. These pulses are reflected back and are received as echoes. It outputs a 4-20mA signal which makes it intrinsically safe. The calibration of the senor is accomplished using a handheld device which uses HART technology. One (1) Kit, Radar PVT Calibration Two (2) Pump Stroke Sensors (Proximity Type) One (1) Flow Out Sensor: Consists of a paddle assembly, which is inserted and attached to the flow line of the rig. The paddle is activated by the returning flow of mud. As the return flow raises the paddle, the shaft to which the paddle is attached also turns. On this shaft is mounted an asymmetrical cam, and as the cam is turned, the distance between the cam and the proximity sensor mounted on the housing is measured and converted into a signal which can be calibrated for the full length of travel of the paddle. Also mounted on this shaft is a counterweight which serves to bring the paddle back to a vertical position when there is no flow in the flow line, as well as provide resistance to flow in order to stabilize the action of the paddle. This entire assembly is attached to the flow line by utilizing a saddle made of angle iron, which is welded over the opening in the flow line through which the paddle is inserted.
