Social media is cool. I’m able to keep up with people in the industry, all over the world. The different methods and equipment make for some interesting conversations. I got into a discussion the other night about derrick design, the different rigs and the reasons for the designs, so I thought I’d share a little of what I’ve learned over the years.
Derricks in the drilling industry basically come in two types: internally loaded and externally loaded. Examples of externally loaded derricks would include a standard Smeal rig or an oilfield workover rig. This means that the load is dispersed to the foundation by transmitting and dividing it on the block to the load on guy wires, or hydraulic cylinders. This design is very handy, as it allows you to rig up over most any hole and allows plenty of working room. Guy wires can be either to the ground or back to the rig itself. Most smaller rigs use guys to the front of the unit, and any ground wires are just for wind stability. Pulling power is often limited by the weight of the unit. I’m sure you have seen or heard about situations that lifted the front wheels off the ground. That’s pretty much the limit, and it’s hard on equipment. Downsides include flex and overall capacity. They will flex and move as loads are increased. These derricks can be built very strong, but the engineering challenges get larger on the big units.
Very common in all classes of the drilling industry are internally loaded derricks. Everyone is familiar with Mayhew, Gardner-Denver and Failing rigs, as well as many others. This includes the biggest oilfield rigs. The rotary, and the load, are inside the derrick. Forces are transmitted directly from the block to the foundation, without external guys or support. These derricks are typically vertical and are self-stabilizing, and don’t require any headache or ground wires. This makes for a very strong and compact unit, but sacrifices working room on smaller rigs.
A well-designed derrick will last a lifetime of daily use — and occasional abuse. Since they are over our heads, we should know, understand and maintain our derricks.
Older designs, such as cable tool rigs, are externally loaded, but have such a tried-and-true design that they’re able to handle most of the loads put on them. Eventually, rotary rigs came along and were internally loaded derricks. These are very strong derricks for their size, which is a good thing. On most water well rigs, the drawworks don’t have enough power to damage the derrick. Whether this is a design feature or an economic consideration, it sure is safer. I’ve seen drillers who would ignore the weight indicator (if they had one) and just “give ‘er hell.” With most water well rigs, they run out of clutches or horsepower before they have a train wreck. Oilfield rigs are different. They have the power to do anything the rig will take, and more. That’s why they have weight indicators and crews are trained to use them. When these derricks take a load, several things happen. They will almost always “squat” with a significant load. This can be anything from half an inch to several inches, depending on load, foundation and design. But they usually stay over the hole. In my years as a borehole fisherman, I have been on many stuck pipe jobs. This generally requires that I pull more weight than the rig sees on a day-to-day basis. Sometimes, the company has strict rules but, sometimes, it is up to the people on the rig as to what their iron will stand. It’s not uncommon to pull way over the rated capacity. When I have to do this, I always look very carefully at everything. As I said, when you load a conventional derrick, it will squat when it takes the load. It will also twist a little, but stay over the hole. However, as you increase the load, most derricks will twist a little more in proportion to the load. When the load is released, the derrick will spring back to its original size and shape. This is normal elasticity. At some point, though, as you increase the load, the derrick will not continue to flex or twist. This is the danger zone, and indicates that you have reached the limits of elasticity of the steel. Been there, done that. It’s not pretty. It’s then time to try a different approach.
Usually, a well-designed derrick will last a lifetime of daily use — and occasional abuse. Since they are over our heads, we should know, understand and maintain our derricks. If you crater a derrick — and live through it — you will have a lot of explaining to do.
Newer rigs are built either way, commonly with box tubing and an external load. These are great rigs and very popular. But, while they allow more working room, they do take more maintenance. I guess it’s what you grew up with and what you are used to.
A. PURPOSE. This instruction provides guidelines to Federal OSHA and Plan States compliance officers, 7(c)(1) consultants, employers, and employees on the stability of well servicing derricks.
C. ACTION. Regional Administrators and Area Directors shall provide copies of the attached Guideline on the Stability of Well Servicing Derricks to the appropriate Federal an State personnel and ensure that copies are available for distribution to the public upon request.
F. BACKGROUND. There have been several fatalitites as a result of derrick collapses caused by the failure of temporary anchors in the oilwell drilling and servicing industry. Since OSHA has no applicable standards, in many of these incidences, our field office have attempted to cite under the General Duty clause, section 5(a)(1) of the OSHact. This action, however, may not be adequate in addressing the problem. Therefore, to assist OSHA compliance officers, State compliance and consultation personnel, employers, and employees, in the recognition of the hazard of derrick collapse due to the failure of temporary stability systems, OSHA contracted Sigma Associates, Ltd. to develop guidelines detailing the type of temporary stability systems, type of soils and its holding capacity, methods of installing guywire anchors, integrity determination of the system, actual pull testing, and acceptable parameters in liew of actual pull testing (Appendix A).
SCOPE: To provide a representative basis for determining the availability, capability, dependability, reliability of Stability Systems on Land Based Work-Over Rigs and the recommended practices and procedures for their safe use.
A typical double derrick with load guys in place in Figure 2-1. The sub-structure is in place and the unit properly configured to begin installation of the guying system. From this configuration determination can then be made as to the proper selection, location, configuration and holding capacity of guy anchors. Load guys should meet manufacturers recommendations. In the absence of manufacturers recommendations, the minimum wire rope diameter should not be less than that which is recommended by a representative of a major, oil field recognized, wire rope manufacturer.
The rig location area may grade away from the well bore along centerline II at a maximum drop of 1:20. The cross grades, parallel to centerline I, should be level. The area shall provide a minimum bearing capacity of 6000 psf.
There are several States which have statutorily addressed the installation of Guy Anchors. The State of Michigan, for example, references the American Petroleum Institute Specification, API SPEC 4E. Alaska requires that Derricks be effectively guyed, braced, or otherwise engineered to resist overturning in accordance with generally recognized safe practices in the industry. (Industry practices are discussed in Section 1).
It should be pointed out that zone determination is a function of angle and distance. Zone "D" will be discussed first for only Single Derricks may be located in this zone and they will require a minimum 10,000 pound anchor, anywhere in the zone. (This is not the case in other zones which will be discussed later.) Zone "D" ranges through all four quadrants. Your attention is directed to the Northeast Quadrant. The zones parameters begin at the 22.5 degree radial and end at the 67.5 degree radial using line segment OE as the zero radial . The nearest point of Zone "D" to the Well Head is 35 feet and is located on the 45.0 degree radial. (see Southwest Quadrant). The far point of Zone "D" on the 45.0 degree radial is 50 feet. (see Northeast Quadrant).
The minimum anchor holding capacity required for any other location and/or other than single derricks will be determined by Zone and horizontal distance from the "Well Head".
Using the chart: An anchor in Zone "A" located a horizontal distance of 70 feet from the "Well Head" would require an anchor of what minimum holding capacity? On the chart move along the horizontal legend from left to right until you reach 70 feet. At this juncture proceed vertical until you intersect the curved line for Zone "A", now follow the intersecting horizontal line, left toward the vertical legend. We have now determined that the minimum holding capacity for the anchor, at this precise location, is 20,000 pounds.
Standing at the "Well Head", with the well bore immediately to your back, proceed North (in direction monkey board is facing) 24 paces. (The pace length is not as important as the numerical relationship of the units and the consistency of the unit length. The method will work with any unit of length as long as the same unit is used throughout.) Place a stake or other marker at this location (Bench Reference). Turn West 90 degrees and proceed forward 10 paces. At this location turn your body so that the front portion of your anatomy is approximately parallel to the radial of the guy anchor. If the northwest guy anchor is forward of your right shoulder and the southeast guy anchor is aft to the rear of your left shoulder, it can then be presumed that the radial angles are within acceptable parameters. Repeat the procedure from the bench reference, this time to the east, proceed ten paces. In this orientation the northeast anchor should be forward of the left shoulder and the southwest anchor should be aft of the right shoulder.
After the location has been selected and the site prepared, erection of the "DERRICK" and its stabilization system can proceed. Presently the API, AOSC and IADC recommend the following basic procedure, with reference to Figure 5-1:
A survey of 13 drilling contractors operation 193 drilling rigs in northern Canada and Alaska indicated that there is a wide range of experience and operating practices under extremely low temperature conditions. While there is very little precise information available, there have been a sizeable number of failures in portable masts while in the lowering or raising process in winter. Thus the exposure to low temperature failures focuses on mast lowering and raising operations. Based on reports, however, this operation has been accomplished successfully in temperatures as low as -50 degrees F. While the risk may be considerably greater because of the change in physical characteristics of steel at low temperatures, operators may carry on "normal" operations even at extremely low temperatures. This may be accomplished by a program of closely controlled inspection procedures and careful handling and operation. This should reduce damage and impact loading during raising and lowering operations. At the present, there seems to be no widely accepted or soundly supported basis for establishing a critical temperature for limiting the use of these oilfield structures. Experience in the operation of trucks and other heavy equipment exposed to impact forces indicates that -40 degrees F may be the threshold of the temperature range at which the risk of structural failure may increase rapidly. Precautionary measures should be more rigidly practiced at this point. The following recommended practices are included for reference:
If maintained to these tolerances the sags will indicate a pretension of 1000 pounds for crown to ground guywires and 500 pounds for tubing board guywires. this is based on the use of 5/8 inch, 6x19, or 6x37 class, regular lay, ips, IWRC wire rope, installed according to the rigging guidelines set forth in chart depicted in Figure 5-5
The drawing on the following page, Figure 5-4, (SAME AS FIGURE 4-4) is another illustration of the continuing evolution of Rig Stability System engineering and design. It represents the latest API thinking relative to planing and preparing a Rig Stability System.
CAUTION: SOLE EMPHASIS SHOULD NOT BE PLACED ON PULL TESTING OR ALTERNATIVES TO PULL TESTING AS THIS MEASURES ONLY ONE COMPONENT OF THE RIG STABILITY SYSTEM.
The rig contractor should be responsible for the following: a. Insuring that anchor capacities are verified and that anchor spacing and capacity is suitable for the mast guying pattern and anticipated loading.
b. Records of pull testing or records of other methods used to verify temporary anchor capacity should be retained by the rig contractor until the job is complete and the guy wires have been removed from the anchors. The records should indicate the capacity of each anchor, the date of verification, name and phone number of the party responsible for verification, and the soil condition at the time of verification.
OUT OF AN ABUNDANCE OF CAUTION IT IS EXTREMELY IMPORTANT TO POINT OUT THAT THE PREVENTION OF RIG UPSET IS DIRECTLY DEPENDENT ON THE TOTAL INTEGRITY OF THE RIG STABILIZATION SYSTEM. THE SYSTEM INCLUDES ALL OF ITS COMPONENTS AND IS ONLY AS SOUND AS ITS WEAKEST MEMBER.
Our research has concluded, that the latest State-of-the-Art in RIG STABILIZATION is to be found in the pending American Petroleum Institute, Recommended Practice for MAINTENANCE and USE of DRILLING and WELL SERVICING STRUCTURES.

One of the rig crew members who gets his name from the fact that he works on a platform attached to the derrick or mast, typically 85 ft [26 m] above the rig floor, during trips. On small land drilling crews, the derrickman is second in rank to the driller. Larger offshore crews may have an assistant driller between the derrickman and the driller. In a typical trip out of the hole (TOH), the derrickman wears a special safety harness that enables him to lean out from the work platform (called the monkeyboard) to reach the drillpipe in the center of the derrick or mast, throw a line around the pipe and pull it back into its storage location (the fingerboards) until it is time to run the pipe back into the well. In terms of skill, physical exertion and perceived danger, a derrickman has one of the most demanding jobs on the rig crew. Some modern drilling rigs have automated pipe-handling equipment such that the derrickman controls the machinery rather than physically handling the pipe. In an emergency, the derrickman can quickly reach the ground by an escape line often called the Geronimo line.
