Section R. 408.15722 - Derrick and mast foundations and guyingRule 5722.
(1) Foundations shall be capable of safely distributing the gross weight of the derrick or mast under the maximum anticipated hook load.(2) Guyline ground anchors shall be any type that satisfies the requirements of subdivision (a) of this subrule. Soil conditions, terrain, and the use of surrounding land determines the most applicable type of anchor. All anchors shall satisfy both of the following requirements: (a) An installed ground anchor, permanent or temporary, shall meet the pullout requirements for the conditions of service. The anticipated climatic conditions, including wind forces, for the geographic area shall be a prime consideration in determining the anchor pullout requirements and pattern spacing. Anchor breaking strength and pullout safety factors shall be in accordance with API SPEC 4E-1974, entitled "Specification for Drilling and Well Servicing Structures," which is adopted herein by reference in R 408.15721(1) (d).(b) Where soil is corrosive, metal components of permanent ground anchors shall be galvanized or otherwise protected against corrosion.(3) For permanent-type ground anchors, the well operator shall make representative pull tests for the geographical area and size and type of anchor involved. Representative pull tests shall be conducted along the anchor working plane. Records of representative anchor pull tests for the area shall be maintained.(4) Permanent anchors shall be inspected before each use by visually checking. If damage or deterioration is apparent upon inspection, anchors shall be pull tested.(5) Temporary ground anchors shall be of such type and so installed to provide pullout strengths which exceed the maximum anticipated guyline pull for the equipment to be used and the conditions of service. Records of representative anchor pull tests for the area and size and type of anchor shall be maintained.(6) A portable mast, either structure or pole type, that requires the use of external guylines to assure stability shall have the external guylines in place immediately following the raising and telescoping of the mast.Mich.
