drawworks. 1. n. [Drilling] The machine on the rig consisting of a large-diameter steel spool, brakes, a power source, and assorted auxiliary devices. The primary function of the drawworks is to reel out and reel in the drilling line, a large diameter wire rope, in a controlled fashion. The drilling line is reeled over the crown block and ...

The Active Heave Drilling (AHD™) drawworks set new drilling standards for compensation, accuracy, improved wireline life, workable load range, and rig safety by ...

drawworks with hoisting performances comparable to a conventional drawworks. The result is a simple design with few mechanical parts, a small footprint, and lightweight. These drawworks require minimal maintenance and are entirely self-contained. Automated Drawworks Systems (ADS) Specifications – NOV DSCG

A drawworks is the primary hoisting machinery component of a rotary drilling rig. Its main function is to provide a means of raising and lowering the traveling block. The wire-rope drill line winds on the drawworks drum and over the crown blockto the traveling block, allowing the drill string to be moved up and down as the drum turns. The segment of drill line from the drawworks to the crown block is called the "fast line". The drill line then enters the first sheave of the crown block and ma…

LDW drawworks have technically advanced features to increase drilling performance, safety, and reliability. The combination of cost-effectiveness and operational efficiency with small footprints, less weight, and reduced noise and vibration adds to the advantages of these solid machines.

The drawworks have however large footprints, i.e., 48-ft (14.6 m) long, 12-ft (3.5 m) wide, and 17-ft (6 m) tall, and weigh more than 340,000 lbs (170 ton) driven via six AC motors, each producing 1500 hp continuously. The main DMC advantage is when handling larger (subsea BOP or casing) loads. It is important to note that DMC systems must be ...

In both the land and offshore markets, NOV offers a full line ...

Drawworks Traveling Block Compensation (DMC) As DSC and CMC “passive” compensation systems are the most ideal deepwater floating vessel compensating system, drawworks -based motion compensation systems (DMC) were developed to actively and more precisely compensate vessel heave over a much larger range of hook loads and different wave trains.

A drawworks is the primary hoisting machinery component of a rotary drilling rig. Its main function is to provide a means of raising and lowering the traveling block. The wire-rope drill line winds on the drawworks drum and over the crown block to the traveling block, allowing the drill string to be moved up and down as the drum turns.

23.02.2015 · Drawworks and Accessories: Operation and Maintenance Safety. The driller is in direct supervision of his men for their tour. It should be noted by all crew members that they are to report any breakdown or failure to their driller as soon as possible. Each breakdown or failure of a system (guard) on the drawworks could be a safety hazard.

Conventional rigs use the motion of the drawworks taking in or feeding out wire rope that is passed through a series of pulleys (sheaves) on the crown ( ...

The driller should know or learn as quickly as possible the limitations or capacity of his men. · A smooth running, well-maintained drawworks ...

The drawworks is a part of the system that rotary drilling rigs use for hoisting, or lifting, the drill stem and casing out of the hole.
