Annular Blowout Preventers

Hydril 's complete line of annular blowout preventersis based on more than 55 years of applicationexperience in all BOP types, sizes, and pressure ranges.There is a Hydril Annular BOP to meet most operationalrequirements in the petroleum industry today, both on thesurface and subsea.

Hydril designs are durable for dependable and efficientoperation. A standard annular BOP will strip drill pipe andtool joints. The packing unit life is reduced when used forstripping operations. It will also close off the annulus or openhole to full working pressure.

The Hydril Annular BOP provides quick, positive closingaction with simplified controls to keep drilling fluids in thehole when a blowout threatens. The universal seal offfeature of the annular blowout preventer permits closure andseal off on drill pipe, kelly, tool joints, or tubing and wirelineas well as the open hole. Maintenance of the BOP is easy,rapid, and economical with the use of standard tools.

The Low Alloy Steel Pressure Vessel represents Hydril's50 years of experience in producing BOPs to provideoptimum strength and stress distribution control. Full-spectrum testing meeting or exceeding API require-ments ensures that the desired safety factors and reliabilityare provided in each unit.

Finite Element Analysis of the body design is themost advanced, in-depth technique of pressure vesseldesign analysis and ensures a structurally sound bodyconfiguration.

Shell (Hydrostatic) Testing of the BOP body meets theAPI accepted industry standards to provide a safe, reliableblowout preventer.

API 16A is the latest API specification covering drillthrough equipment. Hydril is licensed to manufactureBlowout Preventers to these exacting standards. In addition,Hydril preventers may also be certified by such certifyingauthorities as Det Norske Veritas (DNV), American Bureauor Shipping (ABS), or Lloyds of London.

Operating Chambers are Pressure Tested to ratedworking pressure of the BOP or 3000 psi, whichever isgreater. This ensures strength, reliability, safety, andthe ability to over-pressure the chambers in well-controlsituations.

Stainless Steel and Inconel-lined Ring Grooves are available as options.

HYDRIL GX® ANNULAR BOP

The GX . . . the field proven flagship preventerof Hydril's fleetThe GX offers extra performance and serviceability whileretaining the field proven features of Hydril annular BOPs.

The GX delivers extended operating service with fewpacking unit changes, with a design that is simple and easyto maintain in both surface and subsea operations.

The GX will close on virtually any drill stem member orseal off the open bore. Operating volumes are lower, resulting in faster closing times and smaller accumulatorrequirements. Packing Unit fatigue and stripping life havebeen increased beyond previous industry levels for equiva-lent sized Annular BOPs.

The GX allows full control of packoff tightness duringstripping operations, regardless of wellbore pressures.

The structural design, quality and testing of the GXcontinues Hydril's state-of-the-art advances.Here are the field proven Hydril features the GX provides:

■ Simple design – only 2 moving parts, thus fewer areasare subjected to wear meaning less maintenance anddowntime.

■ Proven operating principle provides full packing unitseal off at maximum working pressure on open hole, casing, drill pipe, tool joints, kelly or tubing.

■ Long piston design for optimum stability and reliable

operation.■ Latched Head for fast and easy access to packing unit

and seals.■ Opening Chamber Head to prevent inadvertent

contamination of the hydraulic system during packing unitreplacement.

■ Four large pressure energized lip seals are used fordynamically sealing piston chambers.

■ Replaceable Wear Plate eliminates metal to metal contact between the packing unit inserts and the BOPhead,making field repair fast and economical.

■ State-of-the-art structural design, quality and testingfor optimum reliability.

■ Stainless Steel Lined Connection Ring Grooves forcorrosion resistance.

■ Meets NACE MR-01-75 Material Standards for resistanceto sulfide stress cracking.

■ Fabricated from quench and tempered low alloy steelsuitable for service in both low and high temperature applications.

Balanced PistonPiston stability is assured by Hydril's time proven longpiston design with contact points providing a length-to-diameter ratio approaching 1. This design eliminatesany tendency to cock and bind during operations withoff-center pipe or unevenly distributed accumulationsof sand or cuttings.The GX piston is completely balanced. The opening

and closing chamber areas are of equal size. Thisequalizes the hydrostatic forces exerted on the pistonby the control fluid column in subsea operations. Theresult is a BOP that util izes a constant closingpressure regardless of water depth or mud weight.This piston design is such that the closing pressurerequirements are virtually independent of well borepressures.

Contoured angular tapers on the piston bowlcompress and displace the reservoir of feedablerubber in the back of the packing unit. This designassures optimum rubber feeding and closingefficiency. Movement of the piston to the open positionallows the packing unit to relax to full open bore.

StrippingThe design of the GX effectively controls

posit ioning of the inserts. Whenstripping, the inserts remain fixed as the rubber f lows in and out, al lowingthe alternating diameters of pipe and tool joints to pass through the closed packing unit.

This results in a dramatic increase of the GX packing unit stripping life – to approximately

twice that of similar sized annular BOPs.

Extra Packing Unit LifeThe heart of any annular BOP is its packing unit – andthe GX is no exception. Its packing unit has a greatlyincreased reservoir of high-quality feedable rubber.Because the reservoir of feedable rubber is larger, theGX permits continuous rubber feeding as the boresurface wears.

The packing units reinforcing flanged steel insertsare driven by the rubber during closure and quicklyreach a fixed position where they form a steel ring tosupport the rubber from upward motion under wellborepressure.

Once the inserts reach their fixed position, rubbercontinues to flow inward, effecting a positive seal offon the drill string or the open bore.The rubber is primarily in compression and is there-

fore resistant to tears, cuts and abrasions. The steelinserts stabilize the rubber and control the flow patternto minimize rubber stress.Packing unit life due to routine testing at full working

pressure has been increased beyond previous levels.Because Hydril Company LP manufactures all its ownpacking units, rigid quality control is assured and fieldperformance enhanced.

More Precise ControlTool joints can be stripped through the closed packingunit while a full seal is maintained on the pipe.

The GX packing unit design permits precise controlof packoff tightness, regardless of wellbore pressures.This allows a slight dril l ing fluid leakage to beachieved during stripping operations to providelubrication, optimize pull through forces and prolongpacking unit life.

The result is the ability to strip long strings of pipeand tool joints in or out of the hole at higher wellborepressures.

The GK Annular Blowout Preventer was designed especiallyfor surface installations and is also used on offshoreplatforms and subsea. The GK is a universal annularblowout preventer with a long record of proven, qualityperformance.Only Two Moving Parts (piston and packing unit) on the

Hydril Annular BOP mean few areas are subjected towear. The BOP is safer and more efficient, requiring lessmaintenance and less downtime.A Long Piston with a length to diameter ratio approaching

one eliminates tendencies to cock and bind duringoperations with off-center pipe or unevenly distributedaccumulations of sand, cuttings, or other elements. Thisdesign enhances the ability of the packing unit to reopen tofull bore position.The Conical Bowl Design of the Piston provides a simple

and efficient method of closing the packing unit. With thepiston serving as a sealing surface against the rubberpacking unit, there is no metal-to-metal wear on the sealingsurface and thus longer life results.A Field Replaceable Wear Plate in the BOP Head serves

as an upper non-sealing wear surface for the movement ofthe packing unit, making field repair fast and economical.Maximum Packing Unit Life is possible with the provision

for measuring piston stroke. This measurement indicatesremaining packing unit life without disassembly and ensuresthe longest and safest use of the packing unit.

Two Choices of Packing Unit Rubber Compoundspermit more flexible applications.

The Screwed Head Design of the GK BOP is a simple,efficient, and strong method of connecting the head to thebody for safe operation with no loose parts to be lost downthe hole or overboard.The Latched Head Design is available on the GK, 13-5/8"-

5000 and larger BOPs. It provides fast access to packingunits and seals for minimum downtime with no loose parts tobe lost down hole or overboard.

Large Pressure Energized Seals are used fordynamically sealing piston chambers to provide safeoperation, long seal life, and less maintenance.

Piston Sealing Surfaces Protected by Operating Fluidlowers friction and protects against galling and wear toincrease seal life and reduce maintenance time.

The Operating Chambers are Tested to Full BOPWorking Pressure to ensure strength, reliability, and theability to over-pressurize the chambers in emergencies.Meets NACE MR-01-75 Material Standards for resistance

The GK BOP has been developed especially for use onsurface installations but it is also used subsea. Standardoperation requires both opening and closing pressure. Sealoff is effected by hydraulic pressure applied to the closingchamber which raises the piston, forcing the packing unitinto a sealing engagement. Any normal closing unit havinga separate pressure regulator valve for the annular BOPand sufficient accumulator volume can be used to operatethe GK.

The GK is designed to be well pressure assisted inmaintaining packing unit seal off once initial seal off hasbeen effected. As well pressure further increases, closureis maintained by well pressure alone. Exceptions are the GK7-1/16"-15,000 and 20,000 psi which are not well pressureassisted and closing pressure must be maintained on theBOP to assure seal off. (Refer to the operators manual forclosing pressure curves.)

Stripping OperationsDuring well control operations, drill pipe can be rotated andtool joints stripped through a closed packing unit, whilemaintaining a full seal on the pipe. Longest packing unit lifeis obtained by adjusting the closing chamber pressure justlow enough to maintain a seal on the drill pipe with a slightamount of drilling fluid leakage as the tool joint passesthrough the packing unit. This leakage indicates the lowestusable closing pressure for minimum packing unit wear andprovides lubrication for the drill pipe motion through thepacking unit.The packing unit life is reduced when used forstripping operations.The pressure regulator valve should be set to maintain the

proper closing chamber pressure. If the pressure regulator

valve cannot respond fast enough for effective control, anaccumulator (surge absorber) should be installed in theclosing chamber control l ine adjacent to the BOP –precharge the accumulator to 50% of the closing pressurerequired. In subsea operations it is sometimes advisable toadd an accumulator to the opening chamber line to preventundesirable pressure variations with certain control systemcircuits.

ScrewedHead

Hydril's new Compact GK Annular BOPs are lighter andshorter than previous models. They are designed for use onsurface installations, both drilling and workover applications.The new compact models incorporate the following featuresthat have given the GK a long record of proven and qualityperformance.Only Two Moving Parts (piston and packing unit) mean

few areas are subject to wear. The GK is safer and moreefficient, requiring less maintenance and less downtime.The Long Piston has a length to diameter ratio approach-

ing one. This eliminates tendencies to cock and bind duringoperations with off-center pipe or accumulations of sand,cuttings, or other elements that are unevenly distributed.Conical Bowl Design of the Piston provides a simple and

efficient method of closing the packing unit. With the pistonserving as a sealing surface against the rubber packing unit,no metal-to-metal wear occurs on the sealing surface, result-ing in longer life.Field Replaceable Wear Plate in the BOP Head serves as

an upper non-sealing wear surface for the movement of thepacking unit, making field repair fast and economical.

Maximum Packing Unit Life is possible with the provisionfor measuring piston stroke. This measurement indicatesremaining packing unit life without disassembly and ensuresthe longest and safest use of the packing unit.Two Choices of Packing Unit Rubber Compounds per-

mit more flexible applications.Screwed Head Design is a simple, efficient, and strong

method of connecting the head to the body for safe opera-tion, preventing loose parts from falling down the hole oroverboard.Large Pressure Energized Lip Seals dynamically seal the

piston chambers, allow safe operation, provide long seal life,and require less maintenance.Piston Sealing Surfaces Protected by Operating Fluid

lowers friction and protects against galling and wear toincrease seal life and to reduce maintenance time.Operating Chambers are Tested to Full BOP Working

Pressure to ensure strength, reliability, and the ability tooverpressure the chambers in emergencies.Stainless Steel Connection Ring Grooves are optional.NACE MR-01-75 Material Standards for resistance to sul-

fide stress cracking are standard.

HYDRIL MSP™

DIVERTERS/BLOWOUT PREVENTERS

Hydril MSP-2000 psiThe MSP Annular Blowout Preventer is applicable to subseaor surface installations requiring a 2000 psi universalblowout preventer. As proven by its many field installations,it will deliver long, dependable service life. This BOP willseal off drill pipe, kelly, tool joints or tubing and wireline orcompletely shut off the open hole to full rated pressure.The following outstanding features of the MSP BOP make

it qualified to meet the industry's need for simple and reliableblowout protection. A helicopter lift model of the MSP21-1/4–2000 is also available.The Screwed Head Design of the MSP BOP is a simple,

efficient, and strong method of connecting the head to thebody for safe operation with no loose parts to be lost downthe hole or overboard.The Latched Head Design which is optional on the MSP

21-1/4–2000 BOP provides fast, positive access to thepacking unit and seals for minimum maintenance time.Only Two Moving Parts (piston and packing unit) on the

Hydril Annular BOP mean few areas are subjected to wear.The BOP is thus a safer and more efficient mechanismrequiring less maintenance and less downtime.

Back to Front Feedable Rubber on the Packing Unitenables the packing unit to close and seal on almost anyshape in the drillstring or close off the open bore and to striptool joints under pressure. This safety feature permits confi-dent closure of the BOP at the initial indication of a kick with-out the delay of locating the tool joint.The Conical Bowl Design of the Piston provides a simple

and efficient method of closing the packing unit. With thepiston serving as a sealing surface against the rubberpacking unit, there is no metal-to-metal wear on the sealingsurface and thus longer equipment life results.A Field Replaceable Wear Plate in the BOP Head serves

as an upper non-sealing wear surface for the movement ofthe packing unit, making field repair fast and economical.

Hydril MSP 29-1/2-500 psiThe MSP 29-1/2"-500 psi, developed for use on surfaceinstallations, is a large bore annular type diverter whose 29-1/2" bore permits hole to be drilled full bore with diverter protection. Its large bore permits the setting of large sizesurface casing without removing the diverter. Thus it isalways ready for venting gas flows. Utilizing computerizedfinite element techniques, the original design of the MSP 29-1/2"-500 has been revamped to provide a unit made upof fewer parts to reduce cost. This unit may be ordered foruse in standard service (temperate climates) or for use incold environments such as the North Sea, Siberia, andAlaska where low temperature metallurgy may be required.

This MSP provides an effective means of rerouting the flowof shallow, low-pressure gas. The MSP 29-1/2"-500 can beused either as a diverter or a 500 psi annular BOP.

Only Two Moving Parts (piston and packing unit) on theHydril Annular Diverter mean few surfaces are subjected towear. The Diverter is thus a safer and simpler mechanismrequiring less maintenance and less downtime.

Back to Front Feedable Rubber on the Packing Unitenables the packing unit to close and seal on almost anyshape in the drillstring or close off the open bore and striptool joints under pressure. This safety feature permits confident closure of the MSP-29-1/2"-500 at the initial indica-tion of kick without the delay of locating the tool joint.

The Conical Bowl Design of the Piston provides a simpleand efficient method of closing the packing unit. With thepiston serving as a sealing surface against the rubberpacking unit, there is no metal-to-metal wear on the sealingsurface and thus longer equipment life results.

The MSP Diverter/BOP has been developed as a simple,reliable unit for moderate pressure drilling service, remedialwork, and well servicing. It can be used on surface and subsea installations. MSP 21-1/4"-2000 operation requiresboth opening and closing pressure. The MSP 29-1/2"-500requires only closing pressure. Seal off is effected byhydraulic pressure applied to the closing chamber that raises the piston, moving the packing unit radially inwardinto a sealing engagement. Any normal closing unit having aseparate regulator valve for the annular BOP and sufficientaccumulator volume can be used to operate the MSP.

STRIPPINGCylindrical pipe sections can be rotated and standard sizetool joints can be safely stripped though the closed blowoutpreventer packing unit. The pressure applied to the closingchamber should be low enough to allow a slight leakage ofdrilling fluid as the tool joint passes through the closed packing unit. The drilling fluid lubricates and cools the packing unit, reducing wear caused by rotation or strippingof pipe. Overall packing unit life is reduced when used instripping operations.The operation/maintenance manual for the specific MSPmodel provides specifications and functional guidelines.

Operation as a DiverterWhen using the MSP as a Diverter during top hole drilling,the primary purpose is to divert well flows away from the rigand personnel. This application avoids shutting in the well,but instead permits routing of the f low to a safe distance on the down wind side of the rig.In this application, the MSP is attached directly to the drive

or conductor pipe. Vent lines typically are installed directlybelow the diverter. The lines should be sized in accordancewith API standards to prevent excessive well bore backpressure buildup. This may be accomplished by using aHydril drilling spool between the diverter and the conductorpipe.

The Hydril SXV Spool, described on page 38 of this catalog provides integral venting without external valves.

If valves are to be used in the diverter system, standardsset forth in API RP64 (Recommended Practice for DiverterSystems Equipment and Operation) should be followed.

Operation as a BOPWhen using the MSP as an Annular Blowout Preventer, it

may be hooked up as shown (above, right). In this mode,well control operations can be conducted within the MSP'sworking pressure range

In either mode, pressure applied to the closing chamberraises the piston closing the packing unit to effect the sealbetween the packing unit and pipe. Well pressure or testpressure also acts on the MSP 21-1/4"-2000 piston belowthe sealed off packing unit and further increases the closingforce acting on the packing unit. The MSP 29-1/2"-500 isnot wellbore assisted.

In performance tests, itoutlasted other replacement units by a minimum of 5-to-1.The key to this remarkable performance is a revolutionaryasymmetrical insert design which gives the unit dynamics forlonger life and reliability.

Independent tests conclusively showthe Hydril Long Life "LL" unit farsurpasses other replacement units.The GK 13-5/8"-5000 "LL" packing unit was fatigue testedon 5" drill pipe at full working pressure against three othercurrently available replacement packing units for the HydrilGK 13-5/8"-5000 Annular BOP. In this testing, the "LL" Unitoutlasted the other units by a minimum of 5-to-1.

Greater fatigue life means loweroperating costs.Based on list prices for other available GK 13-5/8"-5000replacement packing units, you can save 65% to 70% . . . ormore . . . on packing unit costs with the Hydril Long Life "LL"

Packing Unit. WIth a life expectancy five times that of otherreplacements tested, Hydril's "LL" Packing Unit was shownto provide 3-1/2 times more closures per dollar.

Operating principles continue with LL designThe Hydril "LL" Packing Unit is designed to provide greaterfatigue life without compromising the stripping performanceand operating characteristics of the Hydril GK and GL BOPs.

Hydril tested for quality assuranceAs with all Hydril packing units, the "LL" unit is factory testedin a blowout preventer at its rated working pressure. So youcan be sure of reliable performance, closure after closure.

One of the most important features of Hydril AnnularBlowout Preventers is the packing unit. These reliable unitsare manufactured by Hydril from high-quality rubber materialreinforced with flanged steel segments. Each size packingunit has a large volume of tough, feedable packing materialsufficient to meet most requirements.

The molded-in steel segments have flanges at the top andbottom. These segments anchor the packing unit within theBOP and control rubber extrusion and flow when sealing offwell pressures. Since the rubber is confined and kept undercompression, it is resistant to tears, cuts, and abrasions.In the open position, the inside diameter of the packing unit

is flush with the full bore of the preventer; bits, drill collars, orreamers pass through freely. The packing unit is squeezedinward when closing pressure is applied to the piston. Thebore of the packing unit conforms automatically in size andshape and seals off any part of the drillstring or seals offcompletely if the tools are out of the hole.Hydril manufactures packing units for the annular BOPs at

its own factory. This allows Hydril to maintain rigid qualitycontrol of packing units.

Hydril Packing Units –Fully Factory TestedEach Hydril packing unit is factory tested in a BOP prior toshipment. The packing unit is tested to 50% of workingpressure on open hole and 100% on pipe. The Certified TestSeal on the packing unit ensures that the unit meets theacceptance requirements based on years of experience anddevelopment in designing blowout preventers for reliablewell control.

SelectionBecause of the importance of the packing unit to theoperation of the blowout preventer and to the safety of crewand rig, only genuine Hydril packing units should be used asreplacements for original equipment. All Hydril packing unitsare tested to full rated pressure inside a test BOP at thefactory as part of rigid standard acceptance tests beforebeing furnished to the consumer.

Packing units for Hydril BOPs are manufactured fromcompounded natural rubber or nitrile rubber.Natural Rubber is compounded for drilling with water-base

drilling fluids. Natural rubber can be used at operatingtemperatures between -30°F to 225°F (-35°C to 107°C).When properly applied, the compounded natural rubberpacking unit will usually provide the longest service life. Thisall-black packing unit is identified by a serial number with asuffix "NR".

Nitrile Rubber (a synthetic compound) is for use withoil-base or oil-additive drilling fluids. It provides the bestservice with oil-base muds, when operated at temperaturesbetween 30°F to 180°F (-1°C to 82°C). The nitrile rubberpacking unit is identified by a red color band and a serialnumber with the suffix "NBR".

Seals for Hydril BOPs are manufactured from a specialnitrile rubber material which provides long, trouble-freeservice in sealing against oil, gas, or water.Expected H2S and CO2 service does not affect selection of

packing unit material. H2S and CO2 service will reduce theservice life of rubber products, but the best overall servicelife is obtained by matching the packing unit material withthe requirements of the specific drilling fluid.Performance of elastomeric materials can vary significantly,

depending on the nature and extent of exposure to hydrogensulfide. The operator should monitor pressure sealingintegrity frequently to assure no performance degradationhas occurred.

Storage Conditions are important for realizing themaximum life of the packing unit. Packing units should bestored in a cool, dry, dark storage area. Atmosphere, lightand heat accelerate deterioration of rubber goods. It is alsoessential to practice "first-in, first-out" when storing packingunits. Other significant storage factors are covered in theapplicable Operator's Manual.

RAM Blowout Preventers

Designed For Workover Blowout Prevention

The Sentry™ blowout preventor is a ram product designedto meet the special needs of workover operations. It isshorter and lighter than Hydril’s standard BOP’s,but doesn’t sacrifice any of Hydril’s traditional strength and reliability.

There is a Hydril ram-type BOP to meet most operationalrequirements on surface or subsea. Hydril BOPs provide quick, positive closure with simple controls, to keep drilling fluids in the hole when normal orabnormal pressures occur.

• Long life is assured through the use of quality materials and workmanship. Fieldreplaceable seal seats and hinged bonnets provide easy access for ram changes, reducing downtime.

• Flexibility is built inwith a wide selectionof options, includingautomatic or manualram locking, blind, variable, pipe and shearrams, and a choice of positioningfor choke/kill line outlets.

• Preventer integrity is preserved in moving and installa-tion as well as operation in hostile environments because

fluid connections are internal to bonnets.

• Safety and reliability are assuredbecause all Hydril ram BOPs

meet the current revision of NACE.Hydril is alsolicensed to

manufacture to APISpecification 16A, and its

preventers have been certi-fied to all applicable standards, including DNV,ABS and Lloyds of London.

RAM LOCKING SYSTEMSFOR CONVENTIONAL BOP

Hydril Ram Blowout Preventers are available with automaticMultiple-Position Ram Locking. Multiple-Position Locking(MPL) allows the ram to seal off with optimum seal squeezeat every closure. MPL automatically locks and maintains theram closed with the optimum rubber pressure required forseal off in the front packer and upper seal.

Front packer seal wear (on any ram BOP) requires adifferent ram locking position with each closure to ensure aneffective seal off. Multiple-Position Locking is required toensure retention of that seal off position.A mechanical lock is automatically set each time the ram is

closed. Ram closure is accomplished by applying hydraulicpressure to the closing chamber which moves the ram to aseal off position. The locking system maintains the rammechanically locked while seal off is retained even afterreleasing closing pressure. The ram is opened only byapplication of opening pressure which releases the lockingsystem automatically and opens the ram, simultaneously.

How MPL worksThe figure above shows the ram maintained closed andsealed off by the MPL. Hydraulic closing pressure has beenreleased. The Hydril Ram Blowout Preventer with MPL automatically maintains ram closure and seal off. MPL willmaintain the required rubber pressure in the front packerand upper seal to ensure a seal off of rated working pressure. MPL will maintain the seal off without closing pressure and with the opening forces created by hanging thedrill string on the ram.

Locking and unlocking of the MPL are controlled by aunidirectional clutch mechanism and a lock nut. Theunidirectional clutch mechanism maintains the nut andram in a locked position until the clutch is disengaged byapplication of opening pressure.Hydraulic opening pressure disengages the clutch plates to

permit the lock nut to rotate freely and the ram to open.

Hydril Offers A Choice ofAutomatic Multiple PositionLocking or Manual Locking OnRam BOPs.

LOW HYDRAULICCLOSING FLUID PRESSURE

LOW HYDRAULICOPENING FLUID PRESSURE

MPL ComponentsThe component parts of the MPL utilize basic mechanismsand proven techniques to achieve reliable and positiveautomatic multiple position locking.

The tail rod is threaded with a fast lead, six path, helicalthread. These threads make three turns per foot.The mating lock nut and clutch assembly screws onto the tail

rod. Tail rod linear motion causes the lock nut to rotate as thepiston moves to close or open the ram.

The clutch assembly permits or prevents lock nut rotation.Preventing lock nut rotation prevents piston motion. The clutchassembly allows unrestrained closing motion. Application ofopening pressure disengages the clutchassembly permittingopening motion.

Incorporated in the MPL is provision for testing the lockingmechanism. Manually operated lockout devices preventopening pressure from disengaging the clutch assembly.Application of opening pressure then simulates opening forcesapplied to the ram thus testing proper functioning of the lock.The lockout device position is visually indicated.

Manual LockingThe manual type lock is shown fully locked. The manual lockcan be set after the ram has been hydraulically closed, toensure retention of seal-off. Clockwise rotation of the tail rodlocks the ram and counter-clockwise rotation unlocks it. Theram can also be closed manually, should failure of thehydraulic system occur. When the ram is open, clockwiserotation of the tail rod closes the ram and locks it. The rammust be opened hydraulically after it has been unlocked.

The screw on the manual lock uses a left hand heavy-dutyacme-type thread and is located within the BOP, where it isprotected from weather, corrosion and external damage. Thethread is protected and lubricated by hydraulic operating fluidfor minimum torque requirement.

Setting of the manual lock, after having closed the ramshydraulically, is facilitated by reducing the closing pressure. Donot reduce the closing pressure when hanging off drillpipe onthe ram blocks. Ram seal is ensured by the wellbore pressure.

HYDRIL VARIABLE RAM

HVR FRONT PACKERS

Each Hydril Variable Ram (HVR)is designed to close and seal on arange of pipe sizes.

Universal Seal OffThe HVR gives a universal seal off feature especially

useful on tapered drill strings and drill pipe that does nothave a constant diameter over its length. Two ram BOPswith HVRs can be used on a tapered string to provide abackup for all drill pipe sizes. This application eliminateshaving one pipe ram for small diameter pipe and one forlarge diameter pipe. If a BOP stack is assembled with ablind or blind/shear ram and two sets of Hydril VariableRams 3-1/2"-6" size, the HVRs will seal on the drill pipe from3-1/2" to 5-1/2", providing the backup seal off capabilityneeded on a tapered string. The HVR is therefore ideallysuited for subsea use by expanding the seal off capability ofone ram assembly within a BOP.

Interlocking I-Beam InsertsThe HVR has a variable front packer with interlocking

I-beam inserts molded into the rubber. These inserts confinethe rubber within the packer and against the pipe thuspreventing extrusion of the sealing element. During seal offon small diameter pipe, the inserts move radially inward tocontact. On large diameter pipe the inserts are displacedinto the front packer. Application of load by the BOPoperator squeezes the sealing element within the confines ofthe inserts and the pipe O.D. This action establishes a steelcontained sealing element. A key feature is automaticadaptation to the pipe size as the ram closes and seals off.

Large Volume ofFeedable Rubber

The ram block upper seal provides a large volume offeedable rubber to deliver a long and dependable servicelife. The HVR operates inside standard Hydril ram blowoutpreventers and utilizes the standard hydraulic operator. Thisdesign permits interchangeability with fixed size pipe rams,casing rams and/or blind rams at any time.

Excellent CompatibilityThe HVR has excellent compatibility with Hydril's proven

automatic Multiple Position Ram Locking Mechanism (MPL)and the Manual Lock Model. The automatic MPL ensures a

positive mechanical lock at all positions of the variable ram. This means the MPL automatically compensates for thedifferent positions the HVR attains when sealing on differentpipe sizes.

Laboratory Tested . . .Field Proven

The Hydril Variable Ram functional reliability has beenproven by extensive field use and testing. HVR field testshave been conducted on wells operated by major oilcompanies. Tests include fatigue testing, which simulatedover a year and a half of service by numerous cyclicoperations and pressure tests of the ram packers.

HVR RAM ASSEMBLY

No compromise in operating capabilities. Hydril’scompact BOPs provide the same reliability andlong service life the industry has come to expectin its standard size ram BOPs.

• Easy field maintenance: Patented bonnet sealpermits low torque makeup, less time to openbonnet and access ram blocks. Fewer bonnetbolts further reduce maintenance time.

• Reduced downtime: Upper seal seats and bottom wear plates can be replaced in service. Noneed to disassemble the stack, remove it from the rig and ship to an offsite repair facility for time-consuming welding, stress-relief and re-machining. The hydraulic manifold is also field replaceable.

• Increased fluid flow capacity: Hydraulic mani-fold design increases fluid flow capacity throughthe hinge by as much as 40 percent.

• Operating flexibility: Hydraulic manifold installson either side of the BOP, permitting change ofbonnet opening side as required to fit variousstack configurations.

Conversion of Hydril High Pressure Ram BOPs toaccept New Bonnet Seal Improves Seal Integrity andLowers Bonnet Bolt Torque.Based on Hydril's record of providing the newest and mostadvanced designs in blowout prevention equipment, Hydrilhas again met the challenge by developing a new patentedbonnet seal that overcomes bonnet gap problems caused byhigh pressures. Minimizing these gaps currently requires theuse of very high BOP bonnet bolt torques on high pressureBOPs. Seal gap problems become more severe in both coldweather and high temperature applications. Standard highpressure seals tend to loose their preload without internalpressure in the BOP which sometimes causes sealing

difficulties at low pressures, especially in cold temperatures.The results of Hydril's new bonnet seal design improves sealintegrity at both low and high pressures and lowers bonnetbolt torque significantly to 1500 - 2000 ft.-lbs.

Hydril's original bonnet seal consists of a single seal ringinstalled in a groove in the bonnet face (see Figure A).Hydril's new bonnet seal design consists of a set of specialcompound O-rings installed in a seal ring carrier. Conversionof the BOPs containing the original style bonnet seal to thenew bonnet seal requires removal of the bonnet, machininga new cavity for the new seal ring carrier, and installing theseal ring carrier and the O-rings in the cavity as shown inFigure B.

Diverters

Hydril diverter systems are designedfor strength and simplicity to providesafe venting of shallow gas flows.The rugged equipment endures sustained punishment from erosion,impact, thrust and pressure loads.Hydril systems are actuated by a single hydraulic signal. By eliminatingsequencing malfunctions, integralventing substantially reduces the riskof catastrophes. In the past, inoperative valves have caused many

accidents. Hydril diverter systems eliminate all these valvesincluding flowline valves, vent line valve, port/starboardvalves and fill-up valves.

Hydril diverters need no insert bushing and the packing elements can close on any pipe in the bore or on the open hole.

Hydril systems have accumulated years of service on numerous world class drilling rigs. Hydril has developed a variety of diverter systems to cover a wide range of rig configurations, well requirements and environmentalconditions.

Rig Survivability. Massive flows of gas and sand can quickly destroy a rig's diverter system. Hydril diverters arestout and built to endure the brutal blast of fluid, rocks andsand. They are thoroughly tested. Valves, insert cartridges, linkages and sequencing processes that frequently causemalfunction are completely eliminated.

Economical, easily installed and maintained.Quick connects, scope and spacer spools enable easy nipple-up and down. Hydril diverters use dependable annular packing units. They are routinely maintained andhandled in the same way as BOP's on the rig.

Hydril diverter equipment can be tailored to any rig,bottom founded, floating or tethered. Arrangements can bemade to permit diverting at the surface and/or subsea. Fullredundancy of surface-subsea options can significantlyenhance reliability.

Simplicity is derived from the patented integral vent designthat eliminates extraneous valves and interconnections.One command, a hydraulic signal, does it all. Upwardmotion of the piston stops the flow of the well fluid andopens the vent line. Fast response time is ensured, sincethere is no waiting for valve functions. Risk of malfunctionduring component sequencing is eliminated.

Subsea diverting provides safety advantages by dissipating destructive forces into the sea, remote from therig. Surface support is spared from impact and erosion.Safety of personnel and rig is enhanced.
