Jack-Up DerricksA variety of Jack-Up derrick designs are offered by MH Pyramid,which typically range from 800,000 lbs to 2,000,000 lbs statichook load. MH Pyramid has an in-house engineering group,capable of supplying a multitude of Jack-Up derrick designs,sizes, capacities and features.

These Jack-Up derricks can be designed with the ability to makeinfield moves with partial setback, while accommodating a vari-ety of other customer-supplied equipment. The capability ofdesign flexibility is our main strength.

The Vertical Beam-Leg Bottleneck Design arranges the derrickwith vertical legs extending from the drill floor to above rackingboard elevation before sloping inward to the top of the derrick.This design expands the setback capacity, while improving drillervisibility, and increasing productivity.

Straight Tapered Leg Design is common for many MH PyramidJack-Up derricks. This features straight tapered legs fabricatedwith angles or beams. In this design, all four legs of the derrickgradually slope inward from the base to the top of the derrick.This design occupies less space on the rig and reduces weight.

Custom Derrick Geometry allows MH Pyramid to design andfabricate custom designs for Jack-Up derricks. With CustomDerrick Geometry, whatever the customer specifications require,MH Pyramid can create it. This custom geometry includesAsymmetrical derricks, derricks with an offset well center tomaximize racking capacity, and derricks with a straight taperon the fastline side with vertical legs on the other side. Thisflexibility allows the customer to decide which design would pro-vide the most optimal scenario.

Standard DerricksOver the years, MH Pyramid has fabricated and delivered wellover 100 standard derricks worldwide to the oil industry. Stan-dard derricks are suited for Jack-Ups and Fixed Platforms, whereprice is a major concern. MH Pyramid Standard derricks relyon a proven, simple design to reduce weight and size for thestructure on the drill floor. This reduced weight allows the con-tractor to put focus on some other portion of the drilling rig toprovide the most optimal solution, in order to increase productiv-ity and profitability.

Standard derrick designs feature straight legs from the drill floorto the crown block. This design reduces weight on the rig, whilemaximizing strength and durability in the process. MH Pyramidstandard derricks are field tested and proven reliable over manyyears on rigs all over the globe.

MH Pyramid offers a wide array of land rig packages and op-tions. These packages include the Fast Moving Land Rig, mul-tiple mast and substructure combinations and desert trailer rigpackages. All of these structures are custom designed in ac-cordance to customer specifications and requirements. Work-ing closely with our customers and other involved drilling equip-ment suppliers, MH Pyramid is able to achieve a successfulstructural integration of drilling components.

Fast Moving Land RigDesigned to accompany the latest in modern technology, theMH Pyramid Fast Moving Land Rig (FMLR) generates fast rigmoves, quick rig-up and rig-down time, decreased transporta-tion loads and improved safety.

The FMLR can be transported in as few as four truck loads,which is a vast improvement over the industry average of triplethat amount. With a rig-up time of two days, the FMLR cuts theindustry average of four days in half. The mast and substructureare raised simultaneously using hydraulic raising cylinders. Theuse of these cylinders creates a faster swing-up time and adecreased safety concern, because it does not rely on drawworkspower and wire lines as a raising system. Safety is also im-proved by setting the drawworks at truck bed height and allow-ing the mast to pin at a height of 3 feet above the ground.

MH Pyramid creates an optimal safety environment with this rigdesign. By reducing the time and resources needed for trans-port and rig-up, MH Pyramid also promotes productivity, therebyenhancing performance and profitability of the rig.

The FMLR is designed to work in conjunction with the latest inmodern controls. This has the ability to adapt to the latestindustry drilling control systems, remote-controlled drawworks,other remote systems and utilizing AC power to drive the rig.As the latest addition to the vast range of rig designs for MHPyramid, the FMLR creates a superlative solution, encompass-ing the best of all worlds into the design, creating the optimalsolution for the next generation of land rigs.




Swing-Up Mast and SubstructureWith the rising industry emphasis on safety and maximizingeffectiveness, MH Pyramid designed the “Swing-Up” mast andsubstructure. Self elevating, Swing-Up masts and substruc-tures are designed to provide a safer, more stable and durablemast and substructure. This is accomplished through state-of-the-art engineering and design principles.

Rig-up is accomplished at truck bed height, eliminating the needfor a crane. All components may be assembled using a ginpole truck. Using the drawworks power, only two lifts are re-quired. First, the mast and setback structure are simultaneouslyraised to the vertical position. Then the drawworks, rotary, floor-ing and doghouse are elevated to operating floor height. Bothlifts utilize reliable sheave and wireline erection system.

Triangular side frame structure allows the drilling loads and vi-brations to be transmitted directly to the bottom boxes. Thisresults in a more stable drill floor. This structure has a large drillfloor, free of A-frames. MH Pyramid masts have no A-frames orA-frame spreaders. Some land rigs require the mast to be pinnedto the A-frame at a high level above the drill floor, creating asafety concern. MH Pyramid masts pin 6 feet above the groundfor easy access and improved safety

Cantilever Mast w/ Box on BoxSubstructureStandard cantilever masts with box on box substructures areavailable in various configurations to handle a broad range ofdrilling capabilities. The box on box substructure is the productof recent design improvements, which allows for maximum flex-ibility, reduced rig-up and rig-down time. These added capabili-ties make this assembly available more quickly and economi-cally than ever before, saving the customer valuable time andresources.

By eliminating most of the traditional diagonal bracing, this newsubstructure can accommodate accessories, such as wind-walls, tool rooms and change rooms. This space-saving designreduces the number of individual structures needed on-site,thereby enhancing the efficiency of used space and materialsover conventional designs. The open box concept also reducesinterference with flowlines, BOP accessories and required main-tenance. Durability, however, has not been sacrificed in thismodel. By design, this is much less susceptible to damagethan any previous model, thereby reducing downtime and maxi-mizing production.

The procedure for erecting this rig configuration eliminates theneed for complicated mast foot ramps. This, in turn, saves thetime consuming and dangerous work of bringing the mast upthe ramps to drill floor height. Instead of cranes, gin-pole trucksare utilized to bring the mast into horizontal position from theground level, reducing the overhead cost of the rig.


Desert Trailer RigsMH Pyramid designed Desert Trailer Rigs for the purpose ofextremely fast rig moves under harsh desert conditions. Theserigs utilize the latest in design techniques to move the mast,substructure and associated drilling equipment. The design ofthese rigs is based on a wheel mounted single or double trailer,fast rig-up and rig-down times (3-1/2 hours maximum), quickmoving and the ability to be towed either forwards or backwards.

The mast, drawworks, rotary table, hydraulic power unit andsubstructure are completely contained on a single trailer withadditional room for customer’s doghouse, air receiver, changehouse or compressor package and drill line spool.

A 22 foot high working floor substructure allows the rig to bemoved on and off wells with up to a 23 foot high by 12 foot wideChristmas tree. The rig affords a 19 foot clear working heightunder the rotary support beams. Built in hydraulic screw jacksallow for fast leveling of the substructure.

This design allows the capability of extremely fast rig moves,which not only increases the effectiveness and profitability ofthe rig, but also increases the safety factor in the harsh desertconditions. The trailer is lowered onto high floatation tires byretracting the hydraulic jacks, which are retracted further to pickup the bearing pads. The rig may then move off the well.

The trailer can be pulled by a truck at the drawworks end withthe mast erect or by a truck at the mast crown with the mastlowered and scoped in. This unit is adaptable to either me-chanically driven or electrically driven drawworks.

Rig Moving EquipmentCustomized rig moving packages are designed for “new-build”structures or retrofitted for existing structures. Rig moving equip-ment are highly specialized and designed according to the typeof rig package to be moved, the environment and other cus-tomer requirements. Working with the customer, the staff ofexperienced engineers at MH Pyramid will take all factors intoconsideration and determine the safest and most efficient rigmoving system design to meet the customer specifications,showing flexibilty and determination to increase the effective-ness and profitability of the customer, as well as itself.




Lift and Roll Rig Skidding SystemThe MH Pyramid Lift and Roll Rig Skidding System transportsthe mast, substructure and setback along an in-line well pat-tern, while the rig is in vertical drilling position. The Lift and RollRig Skidding System is able to skid in X or Y direction, whichmeans from drillers to off-drillers side or from drawworks to V-door side. This added flexibility increases operating efficiencyand reduces downtime needed for infield moves.

The Lift and Roll Rig Skidding System consists of the following:

• Four 200 ton hydraulic lifting jacks• Eight 20 ton rig push/pull skidding jacks• Four 200 ton hardened roller assemblies for straight-

line motion and with vertical guides.• Four roller bases to support the rig on the location foun-

dation and support for the rollers• One set of substructure modification and support mate-

rial to add to the substructure bottom boxes.

The system comes complete with a control console, which in-cludes independent control valves for jacking and independentcontrol valves for skidding. Valves are included to control BOPhandling equipment. The control console has quick discon-nects and hoses included to connect the hydraulic power unitto the rig. The versatility of this control console promotes greatereffectiveness of the operator, which enhances the productivity ofthe rig. An electric power unit for rig skidding and BOP handlingis also included. A skid mounted power unit with reservoir, pumpand hose bracket completes this assembly.

Casing Stabbing BoardMH Pyramid Casing Stabbing Boards are designed for safe travelwithin the drilling structure and is known for long, proven opera-tion service time in environments encompassing the globe. Thecasing stabbing board has a mono-rail track, which providessmoother carriage travel, better visibility and a greater freedomof movement, promoting efficiency of the rig. The boards areadjustable from 23 feet to 47 feet above the drill floor and de-signed to be mounted in a customer specified location. Thedesign allows for carriage to be manuually locked into any posi-tion for added safety.

Casing stabbing boards come with an ABS man riding certifiedwinch with two automatic brakes to control travel. A deadmantype control stops carriage travel when the operator releasesthe safety pull-cord. A dual over-speed device stops the car-riage in the event of wireline failure. The casing stabbing boardincludes a full body harness, that attaches to a retractable over-head safety block by cable.

Space requirements for the system is reduced by the counter-weight carriage platform that folds to storage position when notin use. The carriage platform provides a safe place for the op-erator to stand when carriage is in the stored position.
