The purposes,methodology and limitations on estimation of footing penetration of Jack-up drilling rig are firstly introduced,which is followed by a discussion of the procedures on accurately estimating footing penetration.

In the former group, the insertion of enemator was deeper and in the latter the depth of insertion remained at conventional level.

Clinical study on colon dialysis time and depth of cannula for hepatic cirrhosis patients with intractable ascites;

The major role in the design of cantilever sheet pile is to determine the insert depth and the maximum bending moment.

On the basis of the problem that the tension leveler has a short service life because of work roll s severe abrasion in the pickling line and tandem cold mill(PL-TCM),and in combination with the theoretical analysis and real application in production,the levele s set elongation rate and work roll s insert depth were optimized.
