053-7 Wyo. Code R. § 7-2
(a) Every rig shall be equipped with the number and size of guy wires as recommended by the manufacturer. In the case of truck or trailer mounted rigs where no manufacturer's recommendations are made, appropriate guy wires shall be used. Exception: This rule does not apply when the manufacturer does not recommend the use of wind guys and the following conditions are met:
(b) Every guy wire recommended by the manufacturer shall be utilized according to the manufacturer's specifications.
(c) Where the number, size and utilization of guy wires are recommended by the derrick manufacturer, anchors shall be used to secure the guy wires, except when other means or methods of anchoring the guy wires are recommended by the manufacturer which are at least as effective as these Rules and Regulations.
CLARIFICATION OF SECTIONS 2.(c) (ii) and 2.(c) (iii)
Individual anchors installed, reinstalled or relocated prior to September 25, 1970 will be tested in accordance with Section 2,(c) (ii) (A) and Figure 2a. Individual anchors installed, reinstalled or relocated September 25, 1970, or later, will be installed and tested in accordance with Section 2.(c) (ii)(B) and Figure 2b. This means that the installation of a single anchor subsequent to September 25, 1970, would not require the remaining anchors at the same well site to be tested and installed according to Section 2.(c) (2)(B) and Figure 2b, until such anchor(s) has been installed, reinstalled or relocated. If there is any doubt that individual anchors were installed before September 25, 1970, such anchor's record will indicate this information, and will be tested in accordance with Section 2.(c)(ii) Figure 2b.
- (iv) No derrick shall be rigged up on a work site unless the anchors have been installed and tested in accordance with this subsection.
- (v) All anchor testing units shall be certified by the State of Wyoming Workers' Safety OSHA Division.
- (vi) Guy wire anchors and drilling unit placement.
- (A) Guy wire anchors shall be positioned in accordance with Figure 2a or 2b of this Chapter.
- (B) The well operator shall provide a visible marker in such a position that a straight line through the marker and through the well head will form an angle with a line through any anchor and the well head which complies with the minimum angle requirements as follows:
*Minimum Angle Distances From Well Centerline

*In the use of Figure 2b, if any anchor in the pattern falls within Sector "C", the minimum angle on all anchors is 22.5°. One or more anchors located in Section "B", with the remaining anchors in Sector "A", requires the minimum angle to be 30° on all anchors. In the use of Figure 2a, the minimum angle of any anchor is 22.5°. A field determination of the minimum angle can be found by measuring these distances in convenient units such as feet, yards or paces in reference to the well centerline, the anchors and the longitudinal axis of the unit. (Example: With a single anchor in the pattern located in Sector "C", a person could take twenty four (24) paces from the well head on an imaginary line which bisects the two (2) adjacent anchors between which the unit will be placed. At this point there would be placed a marker or a stake. He would then take ten (10) paces to the left and turn so he was aligned with the well head. If anchors "A" and "C" (Diagram A) are "outside" his alignment, these anchors would be satisfactory. Going back to the center marker, he would repeat this procedure to the right. If anchors "B" and "D" are outside his alignment, the center marker is satisfactory. If alignment to either the left or right was not satisfactory, the center marker or stake would be moved to the left or right as needed and the alignment rechecked until the center marker is located properly.)
- (I) The visible marker shall be placed on a direct line from the well head which passes through the center marker at least 100 feet from the head.
- (C) The drilling unit operator shall center his unit in line with the marker and the well head.
- (D) Where there is provided a readily visible and clearly defined pad for the positioning of the unit which will maintain the required minimum angle from the longitudinal axis of the unit and well to any anchor, the use of the marker in Section 2.(c) (vi)(A)of this Chapter is optional.
- (vii) Guy wires shall not be any closer than ten (10) feet from power lines, and in no case shall a guy wire be extended above or below a power line.
- (viii) Installation, testing and maintenance of guy wire anchors shall be the responsibility of the party issuing the contract for the drilling.
- (ix) All chains, boomers, clamps and tensioning devices that will remain in the working guy line shall have as much strength as the guy line. Those chains, boomers, clamps and tensioning devices not of sufficient strength shall be bypassed by continuing the guy line through or around the anchor, then back to the guy line again. The guy line shall be properly secured with at least three (3) U-bolt clamps of proper size, or their equivalent.
- (A) A fairlead (sheave) may be attached to the eye of the anchor and used to pass the wind guy back to itself.
- (x) A thorough inspection of all guy wires in use shall be made at least once a year and shall be visually inspected prior to each rig-up, and a full written, dated and signed report of the guy lines' conditions kept at the rig where readily available for inspection by department personnel. All inspections shall be performed by a competent person authorized by the employer to perform such inspection. Defects such as those specified in Chapter 5, Section 6.(b)(i) through (ix) of these rules and regulations shall require the guy line(s) to be removed from service.

ANCHOR ELEVATION ADJUSTMENT CHART
Directions for the use of Figure 3. After determining the elevation difference between the well bore ground level and the anchor ground level, find that difference on the chart at "Anchor Elevation Above or Below Well Ground Level". Follow that difference line horizontally until it meets the vertical line which represents the actual distance from the well head or bore to the anchor. Then follow the slanted line, either up or down as applicable, until "0" (Well Ground Level) is reached. Read vertically down and find the "Horizontal Distance From Well - Feet". This adjusted distance is then applied to Figure 1 to determine the required pull test according to the Sector in which the anchor is located. (Example: An anchor located ten (10) feet above well ground level 100 feet from the well head or well bore, using Figure 3, requires the same pull test as though it was 110 feet from the well head or well bore. An anchor fifteen (15) feet below well ground level eight (80) feet from the well head or well bore would require the same pull test as though the anchor was seventy (70) feet from the well head or well bore.)
