location with draft < 6 feet• Submersible barge
ballasted until lower hullrests on soft bottom
• Mud barge also available

Moored vs Dynamically Positioned (DP)Ships and Semis
• No “drive off” risk for moored rigs
• More fuel consumption for DP rigs, high horsepower needed for thrusters (5000-25,000 HP)
• Shorter rig up/down time for DP rigs, allowing fastmoving to avoid hazards
• In general, lower water-depth limit for moored rigs

• Need for heave compensation• Previously done with bumper subs - now use
of passive and active heave compensators

Rig Systems and Components
• Power System
• Hoisting System
• Rotating System
• Circulation System
• Well Control System

5 primary systemsassociated with drilling rig

21
Power System
• Engines: internal combustion engines provide shaft power • Transmission:
– Mechanical - engine shaft power to compound for distribution
– Electrical - engine shaft power to electrical generators &then distributed through silicone controlled rectifier (SCR)that converts AC electrical power to DC for variable speedmotors
7/28/2019 Rig Equipment Presentation
http://slidepdf.com/reader/full/rig-equipment-presentation 22/72
22
Hoisting System
• Drawworks, crown and traveling block -- Deliver hoisting power
to the hook
• Mast/derrick and substructure -- Provide a structural reaction tothe hoisting forces and setback. Setback is the amount of pipeweight that can be vertically racked while the maximum hookload is being carried.
7/28/2019 Rig Equipment Presentation
http://slidepdf.com/reader/full/rig-equipment-presentation 23/72
23
Hoisting System-Hydraulic
• A new type of hoisting system has recently been employed ona few new semis and drill ships. The concept is known as aRam Rig or Hydra Lift Rig. Both concepts use hydrauliccylinders to move the load up and down.
7/28/2019 Rig Equipment Presentation
http://slidepdf.com/reader/full/rig-equipment-presentation 24/72
24
Hoisting System
• Hook, links & elevators -- Provide a force path from the
drill stem to the rotary drill line• Rotary swivel -- Provide for the rotation of the drill stem
with respect to the hook, while providing a force path tothe hook and a fluid path to the drill stem
• Maximum hook load = heaviest string of casing (typically)
7/28/2019 Rig Equipment Presentation
http://slidepdf.com/reader/full/rig-equipment-presentation 25/72
25
Rotating System
• Rotary table -- Deliver rotating power to the drill stem throughthe kelly & associated bushings, usually gear driven from a sideshaft.
• Kelly is typically a 40’ long, square or hexagonal shaped, thick
wall pipe, with a valve (kelly cock) that can be closed to preventbackflow.

Rotating System
• Top drive - Hangs from thehook. Motor providestorque to the drill stemthrough a drive shaft.
• Advantages:1) Rotate while tripping
out2) Can add 3 joints at a
time3) Making up or breaking
out pipe easier

Circulating System - Mud Pits
• Mud pits -- Hold drilling andcompletion fluids
• Various pit sizes – Slug Pits - 30-100 bbls to mix
small batches of fluid- usuallydirectly hooked to hoppers and
mixing lines – Active pits - 100-1000 bbls holdsfluid regularly circulated throughwell
– Reserve pits - 100-1000 bblsholds fluid for reserve use on
well. On land may be earth pit – Sand Trap/Treatment Pits -
usually series of 3 pits wheremud initially returns from solidscontrol equipment. Pump to andreturn from secondary solids
control such as desanders,desilters etc..

http://slidepdf.com/reader/full/rig-equipment-presentation 28/72
28
Circulating System - Mud Pumps
• Mud pumps – 2-3 pistonpumps (often with centrifugalbooster pumps) to circulatemud
• Larger pump cylinder liner for
higher flow rate and smaller liner for higher pressure
• Typically need high flowratefor surface hole and highpressure for production hole

Circulating System - Solids Control
• Shale shaker, desander, desilter & centrifuge -- Provides for theremoval of drilled solids from the drilling fluid upon return fromthe well bore annulus
• Component selection depends on mud weight, mud cost,equipment cost, and disposal cost

Circulating System - Other Mud Treatment
• Gumbo Chain - for handling high volumes of soft-gumboshales- mostly used in GOM top hole sections
• Degassers - for removal of gas from mud stream post solids

Circulating System - Drilling Riser
• As a return mud flow path fromwell at sea floor
• Typically consisting of slip joint,riser joints and LMRP (lower marine riser package) for floaters
• Casing often used as riser for platform drilling
• Riser weight supported bybuoyancy can and tensioner
• Low pressure riser for floatingdrilling and high pressure riser for platform drilling, dual risersfor extreme conditions
• Kill/choke lines attached to riser and booster line used to assistcuttings transport
