(16) Drawworks National Oilwell offers four basic drawworks concepts from its Dreco line which provide some of the most advanced drawworks in the industry:. AC ELECTRIC DRAWWORKS AC electric drawworks offer a unique compact three shaft design ideal for offshore applications where space and weight are of primary importance. Since AC electric motors have wider speed range it is possible to eliminate one gear ratio from the drawworks without decreasing the overall performance of the machine. Primary and dynamic braking is provided by the AC electric motors thus eliminating the need for an auxiliary brake. The regenerated power is pumped back into the main power supply increasing the overall rig efficiency.. • The mechanically driven PSD line • The DC electric chain driven E/UE line • The AC electric chain driven AC line • The AC electric gear driven line which includes the Active Heave Drilling (AHD) drawworks. In addition to the standard Dreco line, National Oilwell manufactures custom drawworks designed to the requirements of our customers.. “SMALL FOOTPRINT” With less transmission parts and no auxiliary brake, the footprints and weights of these drawworks are reduced by up to 30% when compared to a conventional drawworks. Fail safe spring applied disc brakes are utilized for parking and emergency only.. PSD DRAWWORKS Power Shift Drive drawworks utilize a diesel engine and an Allison automatic transmission to provide smooth mechanical power to the drawworks. The drawworks package is small, light and easily adaptable to most small rig packages. All these drawworks are available with mechanical catheads, sand reels, hydromatic brakes and torque tube rotary drives. As another option, these drawworks can be provided with a two speed chain transmission and a DC electric drive.. GEAR DRIVEN DRAWWORKS SSGD DRAWWORKS The AC electric powered Single Speed Gear Driven drawworks offers a design unique to the industry. By overpowering a drawworks with AC motors, we are able to create a single shaft, single speed drawworks with hoisting performance comparable to a conventional drawworks. The result is a simple design with few mechanical parts, a small footprint and light weight. These drawworks require minimal maintenance, are entirely self-contained and completely enclosed. Fail safe spring applied disc brakes are utilized for parking and emergency only.. E/UE DC ELECTRIC DRAWWORKS The E/UE DC electric drawworks provide the industry a machine that matches the others for hoisting capability but with a smaller footprint and less weight. This is achieved by mounting the auxiliary brake on the jack shaft rather than the drum shaft. The drive ratio between the drum shaft and the jack shaft allows a smaller auxiliary brake to be used to achieve the same performance as on a conventional drawworks. This drawworks line is available with mechanical catheads, sand reels, electric or mechanical auxiliary brakes and torque tube rotary drive. Additionally, the drawworks can be equipped with band brakes, disc brakes or a combination of both.. Dimensions, weights, and other specifications for all drawworks are on pages 18 and 19..

(17) Drawwworks. FASTER SPEEDS. ACTIVE HEAVE DRILLING A NEW STANDARD IN TECHNOLOGY FOR SEMI-SUBMERSIBLES AND DRILLSHIPS. With the larger diameter drum, increased hoisting capacity and the enhanced controls, this drawworks will improve operational performance. It will allow for faster tripping, running of risers and setting of the BOP.. Combining the latest technology in controls and design, National Oilwell and Hitec have introduced an innovative product that has proven to be a cost effective solution to drawworks operations. This Active Heave Drilling (AHD) now eliminates conventional overhead motion compensation machinery and allows the Drawworks to provide the active heave along with the hoisting process utilizing regenerative braking.. FEWER MOVING PARTS The ADH drawworks is powered by a single speed, single shaft, direct gear drive system allowing for fewer moving parts. This drawworks has no clutch and gearshift and the mechanical disc brakes are used for parking and holding the load only.. Combined with the capacity of the drawworks, this control system allows for regenerative braking and wave heave compensation to provide a efficient and smooth operation. This system will increase the "drilling operational window" by allowing drilling programs to continue in heavier seas than normal.. Model. Description. AHD-750/1000 Max Hoisting Capacity. ELIMINATES STANDARD MOTION COMPENSATORS, REDUCING WEIGHT IN DERRICK With the reduction of overhead heave compensation equipment weight is removed from the derrick and the center of gravity is reduced further to the drill floor. Added cost savings are seen not only the operation of this system but in the cost of the design and fabrication of the Drillship or Semi with the reduction of overhead weight..

(20) Drawworks Disc Brakes. The Universal Disc Brake System consists of three major components: the discs, the hydraulic system, and the caliper assemblies.. IMPROVED BRAKING RELIABILITY FOR DRILLING RIGS.. THE DISCS.. As drilling depths increase and hookloads get heavier, conventional band brakes are often taxed to their limits. The National Oilwell Universal Disc Brake offers these advantages over conventional band brakes.. The system uses two hardfaced discs machined from alloy steel with an internal water jacket. Disc thickness is three inches. Disc diameter is normally four to five inches greater than the band brake rim.. GREATER HOLDING POWER. The disc brake has significantly. Both braking surfaces on each disc are hardfaced with a weld overlay.. greater resistance to fade than a band brake, and requires less mechanical input force by the driller to control the heaviest loads.. The hardfacing increases disc life and minimizes surface grooving.. LESS DOWNTIME. Change out of brake pads is easy and fast. Unlike most band brakes, there is no need to worry about kinking or other damage during removal and installation. Also, access for maintenance is on the front side of the drum shaft.. THE HYDRAULICS. The hydraulic power unit consists of:. RELIABLE OPERATION. Conservative power ratings, redun-. • A stainless steel hydraulic reservoir.. dancy, and auxiliary back-up systems all assure reliable operation.. • An electrically-driven, variable-displacement, internally pressure-. ACCURATE CONTROL. The brake control system, coupled with. compensated hydraulic pump.. the hydraulics, provide a high degree of control.. • A pressure relief valve.. NO BRAKE HANDLE "KICK-BACK". Dragging brake bands. • Two pressure reducing/relieving valves.. of conventional brakes can cause severe and dangerous brake handle kickback. This cannot happen with disc brakes.. • Four piston type accumulators.. EASE OF REMOTE CONTROL. The brake can be controlled from positions remote from the traditional driller's position without complicated mechanical systems.. • An emergency air-driven pump and two air-piloted hydraulic. LESS NOISE. Significant noise reduction for drilling in noise. • Nickel plated steel block manifold.. valves.. sensitive environments.. In a typical installation, the variable displacement pump is set to maintain maximum system pressure, while the relief valve will open at approximately 200 psi above the maximum pressure. This protects the system in the event of a pump malfunction.. PROVEN. This braking system is being used successfully on a number or rigs.. ADAPTABLE. The disc brake system replaces band brakes, upgrading your present drawworks.. The two primary accumulators, isolated from each other by check valves, supply pressure to the two main valves at the driller's brake handle.. EASY TO RETROFIT. The system is simple to install on existing National Oilwell drawworks.. 20.

(21) Drawworks Disc Brakes. Main (Service) Caliper. Emergency Caliper. The hydraulic accumulators are used to improve response time and provide a short term back up pressure supply in the event the electric and air pumps fail.. Main (Service) Caliper. UNIQUE CALIPERS. THE MAIN SERVICE CALIPER ASSEMBLY. Depending on the size of the drawworks, there are four to six service brake calipers.. SPRING-SET PARKING/EMERGENCY CALIPER. In addition to the hydraulically-actuated calipers, each disc brake system includes two spring-set, hydraulically-released calipers.. Each caliper consists of a stainless steel piston that operates in a hardened stainless steel bushing contained in a stainless steel cylinder, two lever arms, and two brake pad assemblies. Changing pads or replacing calipers requires only a few minutes.. These calipers use a hydraulic piston to compress a stack of Belleville disc springs. During normal operation, hydraulic pressure keeps the springs compressed and the parking brake released.. The cylinders are designed to operate at maximum system pressure however, the normal operating pressure is much less.. However, in the event of complete loss of hydraulic pressure, electrical failure, or by operation of a manual valve, the springs extend and set the brake. Not only do they act when pressure is lost unexpectedly, but they may also serve as a parking brake when the rig is idle for extended periods or while undergoing maintenance. A crown protection device can be installed in the system, which when tripped, activates the calipers.. 21.

(22) Drawworks Disc Brakes DUAL BRAKES FOR GREATER SAFETY. This is actually a dual braking system. The hydraulic circuits for the driller's side and the off-driller's side service caliper assemblies are completely independent.. ADDITIONAL BACK-UP. The air-operated back-up hydraulic pump supplies hydraulic fluid at approximately the maximum system pressure to operate the brake in the unlikely event of a primary pump failure.. ACCURATE CONTROL. The driller can control the main service brakes to a fine degree. Sensitive operations are accomplished with ease.. ELECTRONIC REMOTE CONTROL PACKAGE. With the growing trend to remove the operation of the drilling function to enclosed areas and driller’s cabins, National Oilwell can now offer the ability to electronically control the drawworks functions. Whether use of an existing band brake or with a disk brake system, the interface of the drawworks controls can be safely operated through the electronic control package.. ELECTRONIC JOYSTICK CONTROLS. Safely remove the driller from harsh environments and offer precise control of all of the drawworks functions.. TOUCH SCREEN, MENU DRIVEN. With the provision of electronic driller’s control screen, every function and operation of the drawworks is displayed for ease of operation and can also provide warning signals to prevent dangerous conditions and limits.. The automatic drilling system is designed to relieve the burden of constant actuation of the controls by the driller.. SYSTEM COMPATIBLE. The National Oilwell electronic remote control package can interface with other rig floor systems to provide a reliable, safe and integrated system. With the installation of the National Oilwell electronic drawworks controls, the driller can be assured the operation of the drawworks is performing to the safe design limits and capabilities of the equipment.. CREW SAFETY AND OPERATION LIMITS. When the Energy Monitor System is in operation, the preset limits of safe operation are continuously monitored. If ever these limits are approached, the Energy Monitor System warns the operator of approaching limits. The system automatically applies braking functions when these limits are exceeded to bring the equipment safely under control.. TOTAL PACKAGE. With the addition of the Energy Monitor and Autodriller System a complete package which provides not only operator interface, but additional safety features to maintain safe and reliable operation in harsh environments.. AN IMPORTANT OPTION. To take full advantage of the benefits afforded by the Universal Disc Brake System, National Oilwell offers an integrated PLC based Energy Monitor and Autodriller System. This system ensures that the maximum kinetic energy of the traveling equipment is not exceeded, while monitoring the position of the traveling equipment within preset limits of travel. It also provides precise control of bit weight when drilling.. 22.

(24) Power Swivels PATENTED DUAL LOAD-PATH.. National Oilwell Power Swivels are the result of the company's long history of building rugged efficient drilling machinery products. The following six basic models offer numerous configurations to meet rig designs and anticipated drilling conditions.. Below: Casing and tripping loads are carried separately from drilling loads. They do not pass through the swivel stem, swivel bearing, or API rotary shouldered connections. The Dual Load Path isolates the main swivel bearing and stem from the high stresses, impact loading, and fatigue that are associated with tripping and casing handling activity.. All current design models have the following basic design features. Features of specific models are found on page 27.. AVAILABLE MODELS DC OR AC MOTORS Model. Drilling load capacity.

(25) Power Swivels NATIONAL OILWELL POWER SWIVEL ADVANTAGES:. PATENTED SPRING-MOUNTED ROLLER SYSTEM. Two-stage cantilever leafspring design is standard on both dual guide track and monotrack installations. Wheel trucks distribute forces symmetrically about the centerline. This reduces guide track fatigue failure which occurs in other systems. Bending moment is also reduced on the drive stem and IBOP’s.. • 10% to 30% reduction in drilling time. Fewer pipe connections when drilling ahead.. • More efficient control of directional drilling tools with fewer connections and reduced time required for resetting tool orientation.. • Reduced reaming time using triple lengths of pipe and faster setup for back reaming.. • Maintenance friendly design reduces downtime 30% compared to other designs.. • Better control of mud circulation, with the ability to circulate drill. IBOP ASSEMBLY.. mud while tripping in/out, reducing the risk of stuck pipe.. The upper IBOP has two rotary vane actuators or annular piston type air actuators which provide direct torsional operation. This eliminates binding and overhung moment. The actuator installation eliminates stress-risers of grooved IBOP bodies.. • Significant reduction of time required to reconnect to drill pipe and re-establish well control.. • Efficient tool joint make-up with accurate control of torque for improved drill pipe life.. ROTATING & LINEAR SIDE SKIDS. With the popular patented rotating side-skid option (available with dual guide track applications) the swivel can be rotated to the side in less than 10 minutes, when a standard hook is used. With the Power Swivel off to the side, tripping proceeds faster, with less equipment wear and with lower power requirements. Most routine swivel maintenance can be performed while tripping proceeds, virtually eliminating down-time. For mast applications, or where space is limited, a linear side-skid arrangement is also available.. MAKE-UP / BREAK-OUT SYSTEM. The Power Swivel uses controlled AC or DC motor torque for makeup / break-out of the drill pipe connection. Non-rotating pipe-grabs are powered by a self-contained air-over-hydraulic system. No separate hydraulic power system is required.. PIPE-HANDLING ASSEMBLY. Below: The four-position link kick-out allows for retracting elevators while drilling. The handling ring assembly rotates a full 360 degrees continuously and is lockable.. GEAR BOX & TWO-SPEED TRANSMISSION DESIGNS. All gear boxes have fully supported input shafts providing the most accurate gear mesh for long, trouble-free, running life.. MOTOR MOUNTING. The DC or AC drive motor is foot mounted above the washpipe and mud lines, driving through a shaft with crown-tooth couplings. This greatly reduces sensitivity to alignment, and isolates motor shaft and bearing from over-hung loads.. 25.

(26) Power Swivels PATENTED JOINT LOCKING CLAMPS.. "MONO-TRACK" GUIDE SYSTEM. Patented joint locking clamps assure retention of proper make-up torque relative to Power Swivel stem and IBOP connections. Unintentional break-out or over make-up is prevented.. The PS-350/500, shown at left, the PS-500A, and the PS2-500A are available with a single Mono-Track guide system. It fits most land cantilever masts. It reacts drilling torque into the lower portion of the mast or A-frame. Torque reaction into the upper portion of the mast is eliminated. The mono-track is available for use in mast applications on land rigs and platform rigs.. COMPREHENSIVE CONTROL CONSOLE. The stainless steel purged cabinet includes: RPM meters, torque/amp meters, drilling controls, pipe handling controls, indicator lights, & alarms.. PS-650/750 POWER SWIVEL BLOCK. The PS2-650/750 is available with a special Power Swivel Block. It is available as a direct replacement for standard traveling equipment. It provides the shortest length block and Power Swivel combination. This allows for operation in smaller masts and derricks.. Safety interlocks and safety controls protect the system. Make-up and break-out are automatically controlled. Damage to tool joint threads during spin-in is prevented. Controls provide separate adjustable drilling and make-up torque limits as well as precise control of break-out operations..

Various design models may have different hood capacities; always check with your National Oilwell representative before heavy applications are hung.. SHEAVES All National Oilwell sheaves feature our unique Bearing Retention System, a simple but effective method of preventing a sheave from “walking” off the bearing. The system consists of snap rings which are inserted into grooves machined into the bore of the sheave, one on each side of the bearing cup. A thinner version of a standard seal completes the system.. • API #8C. • DnV approved for UKDOE, NMD and NPD requirements. • Fabricated from top quality materials. • Full penetration welds at hubs. • Rims compression fit to webs before welding. • All welds fully inspected. • Stress relieved after welding. • Grooves hardened to Rockwell C35. • National Oilwell bearing retention system. • Three coat epoxy paint system. • Common sizes stocked.. 29.
