(a) Four (4)
crown-to-ground guys of at least five-eighths (5/8) inch diameter, 6 x 37
class, improved plow steel or steel of higher breaking strength shall be used
on every rig up. Exception: This rule does not apply when the manufacturer does
not recommend the use of wind guys and the following conditions are met:
(1) no one is in the mast during operation,
(2) no rod, tubing, etc. is racked
in the mast,
(3) outriggers are
utilized, and
(4) the mast height
is 60 feet or less.
(b)
Two (2) racking boards-to-ground guys of at least nine-sixteenths (9/16) inch
diameter, 6 x 37 class, improved plow steel or steel of greater breaking
strength shall be used in every rig up where tubing is in the board.
(c) A thorough
inspection of all wind guy
anchor lines in use shall be made at least once a year, and shall be visually
inspected prior to each rig up. All inspections shall be performed by a
competent person authorized by the employer to perform such inspection. Wire
ropes with any of the following defects shall be removed from service as wind
guy anchor lines:
(i) When three (3) broken
wires are found in one lay of 6 x 6 wire rope;
(ii) When six (6) broken wires are found in
one lay of 6 x 19 wire rope;
(iii)
When nine (9) broken wires are found in one lay of 6 x 37 wire rope;
(iv) When eight (8) broken wires are found in
one lay of 8 x 19 wire rope;
(v)
When wire ropes not described herein are found to have four (4) percent of the
total number of wires composing such wire broken in one lay;
(vi) When marked corrosion appears;
(vii) When corroded or broken wires at end
connections are noted;
(viii) When
end connections are corroded, cracked, bent, worn or improperly applied;
or
(ix) When evidence of kinking,
crushing, cutting or unstranding are noted.
(d) All chains, boomers, clamps, and
tensioning devices remaining in the working guy lines 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.
(i) Fairlead (sheaves) at least in strength
to the anchor may be used in the eye of the anchor.
(e) Guy line anchors, including expanding
anchors, pipe anchors, concrete anchors, or other
approved techniques shall be
used, except that temporary, moveable or driven stakes shall not be used.
Locations of all anchors shall be marked with an appropriate marker that
extends a minimum of 24 inches above ground level.
Exception: This
rule does not apply when the manufacturer does not recommend the use of wind
guys and the following conditions are met:
(i) no one is in the mast during
operation;
(ii) no rod, tubing,
etc. is racked in the mast;
(iii)
outriggers are utilized; and
(iv)
the mast height is 60 feet or less.
(f) Anchor placement and pull tests.
(i) With respect to anchors installed,
reinstalled or relocated on or before September 24, 1970, anchors shall be
proof-tested along an angle that approximates the wind guys working plane
within the anniversary or 12th month prior to the use of the anchors. EXAMPLE:
An anchor pull tested in January 1992 shall be usable through the last day of
January 1993, likewise an anchor tested on June 10, 1994 is good through June
30, 1995. Such tests will be at the poundage determined by the anchor's
location (per Figure 5a) within Sector A, B, or C, and computed according to
the appropriate sector curve on Figure 4a. If either of the two front anchors
fall in a sector which requires a higher test pull, both front anchors shall be
tested as if they were located in the sector requiring the higher pull test. If
is frozen at the time of the test and anchors are to be used again when the
ground is not frozen, the anchors must be retested before use. If any anchor is
more than three (3) feet above or below the well ground level, Figure 6 shall
be used to determine the adjusted distance for which the pull test requirement
will be established using Figure 4a. Anchors to be used for singles derricks
only shall be proof-tested to 10,000 lbs. and must be located within Sector A,
B, or C of Figure 5a.
(ii) With
respect to anchors installed, reinstalled or relocated on or after September
25, 1970, anchors shall be proof-tested along an angle that approximates the
wind guy's working plane within the anniversary or 12th month prior to the use
of the anchors. EXAMPLE: An anchor pull tested in January 1992 shall be usable
through the last day of January 1993, likewise an anchor tested on June 10,
1994 is good through June 30, 1995. Such tests will be made at the poundage
determined by the anchor's location(per Figure 5b) within Sector A, B, or C,
and computed according to the appropriate sector curve on Figure 4a. If any
anchor falls in a sector which requires a higher test pull, all four (4)
anchors shall be tested as if they were located in the sector requiring the
higher pull test. If ground is frozen at the time of the test and anchors are
to be used again when the ground is not frozen, the anchors must be retested
before use. If any anchor is more than three (3) feet above or below the well
ground level, Figure 6 shall be used to determine the adjusted distance for
which the pull test requirement will be established using Figure 4a. Anchors to
be used for singles derricks only shall be proof-tested on 10,000 lbs. and must
be located within Sector A, B, or C of Figure 5b.
(g) No oil or gas
well servicing unit shall
be rigged up on a work site unless wind guy anchors have been installed and
tested in accordance with this section. Exception: This rule does not apply
when the manufacturer does not recommend the use of wind guys and the following
conditions are met:
(1) no one is in the mast
during operation,
(2) no rod,
tubing, etc. is racked in the mast,
(3) outriggers are utilized, and
(4) the mast height is 60 feet or
less.
(h) Wind guy
anchors and servicing unit placement.
(i)
Wind guy anchors shall be positioned in accordance with Figure 5a or
5b.
(ii) 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:

* In the use of Figure 5b, 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 Sector "B", with the remaining anchors in Sector "A",
requires the minimum angle to be 30° on all anchors. In the use of Figure
5a, the minimum angle of any anchor is 22.5°. A field determination of the
angle can be found by measuring these distances in convenient units such as
feet, and/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", one could take 24 paces from the well head on an
imaginary line which bisects the two adjacent anchors between which the
servicing unit will be placed. At this point there would be placed a marker or
a stake. One would then take 10 paces to the left and turn so as to be aligned
with the well head. If anchors "A" and "C" (Diagram A) are "outside" the
alignment, these anchors would be satisfactory. Going back to the center
marker, one would repeat this procedure to the right. If anchors "B" and "D"
are outside one's 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.)
(A) 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 well.
(iii) servicing unit operator shall center
his unit in line with the marker and the well head.
(iv) Where there is provided a readily
visible and clearly defined pad for the positioning of the servicing unit which
will maintain the required minimum angle from the longitudinal axis of the unit
and the well to any anchor, the use of the marker in h.(2) is
optional.
(i) Each
well
site shall have available at such
well site in an accessible, weatherproof
container, or in a field office within a five (5) mile radius of the
well, an
Anchor Record. Such Anchor Record shall state the date the anchor was
installed, prior to, or subsequent to September 24, 1970, the date of any
relocation or reinstallation of any anchor at the
well site after September 24,
1970, each anchor's pull test (sector) from Figure 5a or 5b, and the date,
total amount of such pull test, and identification of the tester. This rule
does not apply when the manufacturer does not recommend the use of wind guys
and the following conditions are met:
(1) no
one is on the mast during operation,
(2) no rod, tubing, etc. is racked in the
mast,
(3) outriggers are utilized,
and
(4) the mast height is 60 feet
or less.
(i) Each anchor shall be pulled and
held for a period of two (2) minutes after all movement (creep) has
stopped.
(ii) The anchor record
shall state "FOR SINGLES DERRICKS ONLY" if the anchors are only tested to
10,000 pounds.
(j) All anchor testing units shall be
certified by the Workers' Safety and Compensation Division.
(k) Wind guys from crown or tubing (racking)
board shall not be any closer than 10 feet from power lines, and in no case
shall a wind guy be extended above or below a power line.
(l) Installation, testing and maintenance of
guy line anchors shall be the responsibility of the well operator. The well
operator shall not permit erection of doubles derricks on anchors proof-tested
for singles derricks.
(m) Employers
shall not erect any doubles derricks on anchors proof-tested for singles
derricks.
(n) Gin pole operations
shall be performed in accordance with 1910.181, Wyoming Occupational
Health and Safety 1910-General Rules and Regulations.
(o) Guying of masts in accordance with
manufacturer's recommendations when such guying patterns meet or exceed the
requirements as set forth in Figure 5a and 5b shall be permitted.
ANCHOR ELEVATION ADJUSTMENT CHART
Directions for use of Figure 6:
After determining the elevation difference between the well
ground level and the anchor ground level, find that difference on the Figure
designated "Anchor Elevation Above or Below Well Ground Level". Follow that
difference line until it meets the vertical line which represents the actual
distance from well head to the anchor. Then follow the slanted line, either up
or down as applicable, until "0" (Well Ground Level) is reached. Read
vertically, and read the "Horizontal Distance from Well Feet". This adjusted
distance is then applied to Figure 4 to determine the required pull test
according to the Sector in which the anchor is located. (Example: An anchor
located 10 feet above well ground level 100 feet from the well head would,
using Figure 6, require the same pull test as though it was 110 feet from the
well. An anchor 15 feet below well ground level 80 feet from the well head
would require the same pull test as though it was 70 feet from the well
head.)
