Sentence examples for rock berm from inspiring English sources
To verify the accuracy of the proposed analytical method, model tests were carried out by using three scaled Hall anchor models and dragging them through rock berm.
The movement of a Hall anchor in rock berm is interpreted based on the equilibrium conditions for resisting and driving moments acting on the anchor.
The good agreements indicate that the proposed method is accurate enough to calculate the minimum buried depth of pipeline in rock berm during pipeline design.
An analytical method is proposed in this paper to calculate the maximum embedded depth of a dragged Hall anchor when passing through rock berm and to thus define a minimum buried depth of pipelines in rock berm to prevent pipelines from being damaged by dragging anchors.
The comparisons between the two studies show that the average value of their differences for the stable embedded depth of a Hall anchor in sand and in rock berm are only 1.7%and2.7%7%, respectively.
Spans that are found to be critical with respect to VIVs are usually corrected by placing rock berms below a pipe to shorten the span lengths and increase the natural frequency of the spans.
In addition to the cost implication of placing a large number of rock berms on the seabed, the main disadvantage of this approach is that feed in of expansion into the spans is restricted.
It is, therefore, advantageous with respect to minimizing buckling that the number of rock-berm free-span supports is kept to a minimum.
To this end, physical model tests were carried out and data were analyzed to characterize rock toe berm stability in very shallow water and with a bottom slope m = 1/10.
Glentress is brilliant for families with a great atmosphere, breathtaking views and fun terrain including the rock drops and berms of Spooky Wood, and wooden beams and obstacle tests at Ewok Village.
Based on test results, a new formula was developed with three parameters to estimate the nominal diameter (Dn50) of the toe berm rocks: water depth at the toe (hs), deep water significant wave height (Hs0), and deep water wave length (L0p).
