DR I L L I NG S Y S T E M S DirectDrive Top Drives Fully integrated systems with purpose-built AC electric motor and gearbox-free design. LEWCO DirectDrive Top Drives High Torque Performance LEWCO™ DirectDrive™ top drives from Cameron are manufactured for high performance and reliability in drilling applications. The drillstem of the patented LEWCO DirectDrive top drive is directly coupled to the purpose built AC electric motor, which eliminates the need for a gearbox, along with the bearing, gearing, maintenance and lubrication problems associated with the gearbox. The result is a low-maintenance, high-performance, high-reliability top drive designed for high torque, severe duty drilling applications, such as directional drilling. A Fully Integrated System Available in 500, 750 and 1000 ton load ratings, LEWCO DirectDrive top drives are built to improve drilling efficiency, performance and reliability. The simple, innovative design of the LEWCO DirectDrive top drive reduces the number of complex components, while its redundant speed-sensing capability helps enhance operational reliability. Built tough to withstand the most demanding drilling applications, each LEWCO DirectDrive top drive is designed, manufactured and tested to API (8C PSL1 and Q1) standards, with third party certifications available from industry recognized organizations including ABS and DNV, as well as hazardous area certifications such as ATEX. The system includes: • Thread compensator system • • Through-shaft design AC drilling motor Infinitely positionable pipe handling system and link tilt • ual valve IBOP well control D system • Electrical/control service loop kit • Derrick termination kit • Flexible top drive dolly • Elevator links • Integrated disc brake system • Integrated open loop motor cooling system • 2 Infinitely positionable rotary head system with locking clamps and rotary union DR I L L I NG S Y S T E M S OEM AC Motors The OEM™ AC motor used in the DirectDrive top drive possesses a unique set of characteristics that make it well suited to drilling without a gearbox in a wide variety of both land and offshore applications. These characteristics include: • eliable high-torque/low-speed design well suited for demanding R applications which require more torque, such as directional drilling • Inverter duty motor with Class H insulation system and high-quality formed coils, which allow for greater slot fill, increasing the copper content of the motor and its efficiency over the entire operating range • obust frame, large-diameter hollow shaft and oversized premium R bearings • Hazardous area rating availability and wide ambient temperature range LEWCO DirectDrive Top Drive Specifications Model DDTD-500 DDTD-750 DDTD-1000 Hoisting capacity 500 short tons 750 short tons 1000 short tons Drilling capacity 500 short tons 750 short tons 750 short tons Continuous torque 42,500 ft-lbs 0 - 115 rpm 72,000 ft-lbs 0 - 116 rpm 94,000 ft-lbs 0 - 112 rpm Intermittent torque 80,000 ft-lbs 0 - 115 rpm 100,000 ft-lbs 0 - 116 rpm 130,000 ft-lbs 0 - 112 rpm 930 from 115 - 240 rpm 1575 from 116 - 240 rpm 2075 from 112 - 240 rpm Static brake capacity 35,000 ft-lbs 57,000 ft-lbs 65,000 ft-lbs Pipe clamp capacity 80,000 ft-lbs 110,000 ft-lbs 110,000 ft-lbs 3” 4” 4” IBOPs, remote-actuated upper and manual-actuated lower 15,000 psi 15,000 psi 15,000 psi Hook weight 43,500 lbs 65,000 lbs 105,000 lbs 23.8 ft 28 ft 31.3 ft 7 ft x 5 ft 8.2 ft x 5 ft 9.4 ft x 6.8 ft DirectDrive variable AC motor performance1 Continuous horsepower Mud passage @ 7500 psi Stack-up height Width x depth All specifications are subject to change.
