Deadline anchor is effective component used together with weight indicator to measure the drilling tools weight and drilling pressure.

    


Deadline Anchor
        Hydraulic cathead systems are used to make up and break out drill pipe and drill collars
        Typically, two hydraulic catheads are mounted and operated in pair. Both are controlled
        from the operator chair in the drilling control room (DCR). The hydraulic cathead system
        can also be hydraulically operated at the common valve cabinet, commonly installed on the
        drill floor. Its hydraulic drive limits the risk of electrical hazards in explosive areas,
        as well as reduces system downtime and maintenance. The common valve cabinet contains the
        hydraulic components, including proportional valves, pressure transmitters and a junction
        box to control and monitor the pull from both hydraulic catheads. One calibrated torque gauge
        is mounted in the valve cabinet beside handles for local operation.

Draw works

A draw-works is the primary hoisting machinery that is a component of a rotary drilling rig. Its main function is to provide
        a means of raising and lowering the traveling blocks. The wire-rope drilling line winds on the draw-works drum and
        extends to the crown block and traveling blocks, allowing the drill string to be moved up and down as the drum turns.
        The segment of drilling line from the draw-works to the crown block is called the "fast line". The drilling line then
        enters the sheaves of the crown block and it makes several passes between the crown block and traveling block pulleys
        for mechanical advantage. The line then exits the last sheave on the crown block and is fastened to a derrick leg on the
        other side of the rig floor. This section of drilling line is called the "dead line".
A modern draw-works consists of five main parts: the drum, the motor(s), the reduction gear, the brake, and the auxiliary brake.
        The motors can be AC or DC-motors, or the draw-works may be connected directly to diesel engines using metal chain-like
        belts. The number of gears could be one, two or three speed combinations. The main brake, usually operated manually by a
        long handle, may be friction band brake, a disc brake or a modified clutch.

        An iron roughneck is a piece of hydraulic machinery used to "handle" (connect and disconnect)
        segments of pipe in a modern drilling rig. The segments can be manipulated as they are hoisted
        into and out of a borehole. This type of work was previously performed manually by workers using
        tongs and was one of the most dangerous jobs in a drilling operation. However, with iron roughnecks
        and modern technology, much of this can be done remotely with minimal manual handling. Automated
        roughnecks became common in deep-water drilling and were later adopted by onshore rigs

        Mechanized Catwalk System

The Mechanized Catwalk System (MCS) simplifies and speeds up pipe handling from the pipe rack to the drill floor. By lifting the pipes to the drill floor, they can be directly picked up by an elevator
Personnel on the drill floor operate the Mechanized Catwalk System by remote control panel, eliminating any risk to their safety.

Mechanized Derrickman System

The Iron Derrickman is the only compact, semi-automated pipe-handling system in the industry that fully eliminates the
        need for rig personnel to handle pipe during tripping operations.

 Unlike other mechanized pipe-handling solutions that push pipe into the racking-board fingers and require roughnecks
        to tail the pipe across the drill floor, the Iron Derrickman system uses industrial robotics to transport pipe
        from the well center to the racking board. The automated system lifts and racks triple stands of pipe, heavyweight
        collars, and drill collars with programmed, sequential movements—creating a completely hands-free tripping operation.

Mud pumps

A mud pump is a reciprocating piston/plunger device designed to circulate drilling fluid under high pressure down the drill
        string and back up the annulus.
A mud pump is a large reciprocating pump used to circulate the mud (drilling fluid) on a drilling rig. It is an important
        part of the oil well drilling equipment.[1]
Classification
According to the acting type
Mud pumps can be divided into single-acting pump and double-acting pump according to the completion times of the suction and
        drainage acting in one cycle of the piston's reciprocating motion.
According to the quantity of liners (piston/plunger)
Mud pumps come in a variety of sizes and configurations but for the typical petroleum drilling rig, the triplex
        (three piston/plunger) mud pump is the pump of choice. Duplex mud pumps (two piston/plungers) have generally
        been replaced by the triplex pump, but are still common in developing countries.

Pipe Guide Arm

The pipe guide arm is designed exclusively for use on deep drilling rigs. It guides the drill pipe or casing from the
        handover position at the V-door to the center of the well, but can also be arranged to move the drill pipe from
        the center of the well back to the handover position at the V-door.
The Pipe Guide Arm is moved via a hydraulic and telescopic cylinder. It is specially designed for rough conditions and
        provides a higher HSE level.
Hands-on manipulation of the tubes is no longer necessary: The pipe guide arm significantly reduces possible accidents
        according to IADC Safety Statistics Report.
The pipe guide arm is suitable for all onshore and offshore rigs.

Topdrive

Tropdrive A device that turns the drillstring. It consists of one or more motors (electric or hydraulic) connected
        with appropriate gearing to a short section of pipe called a quill, that in turn may be screwed into a saver
        sub or the drillstring itself. The topdrive is suspended from the hook, so the rotary mechanism is free to
        travel up and down the derrick. This is radically different from the more conventional rotary table and
        kelly method of turning the drillstring because it enables drilling to be done with three joint stands instead
        of single joints of pipe.
modern topdrives are a major improvement to drilling rig technology and are a large contributor to the ability
        to drill more difficult extended-reach wellbores. In addition, the topdrive enables drillers to minimize
        both frequency and cost per incident of stuck pipe.

    


Topdrive
Traveling block

The set of sheaves that move up and down in the derrick. The wire rope threaded through them is threaded (or "reeved")
        back to the stationary crown blocks located on the top of the derrick. This pulley system gives great mechanical
        advantage to the action of the wire rope drilling line, enabling heavy loads (drill string, casing and liners)
        to be lifted out of or lowered into the wellbore.
