Engineering calculations for anchors

06 September 2019 Who can help me out with contacts or information that can broaden my knowledge on anchoring engineering calculations for surface diverter/panic lines?

“Anchors should be installed and placed based on spacing from engineering calculations or guidelines for the expected forces to be encountered. All anchors must be appropriately engineered for the potential static and dynamic forces in the case of a failure.

Deadmen anchors normally have 3-4 expandable wings with a pointed-end structure that bites into the soil for maximum grip. Clamped-stakes anchors are made of two stakes that are connected together via a clamp fitted around the pipe that is being secured. Stakes alone do not suffice as anchors.

Concrete block anchors must be designed to straddle or bolt onto the flowback iron and must be of sufficient weight to prevent movement of the anchor in case of a line failure.

Helical anchors consist of one or more helix-shaped bearing plates attached to a central shaft, which is installed by rotating or "torqueing" into the ground. Each helix is attached near the tip, is generally circular in plan, and formed into a helix with a defined pitch. Helical anchors derive their load carrying capacity through both end bearing on the helix plates and skin friction on the shaft.“
