There are many .31 holes for installation and stabilization of an offshore drilling one-column base, which alternately lower and extend the casing string, immerse in the strings of the wet bottom of the string with the help of water rigs, which are also well-known for uplifting the base TDv6 into the ground by the sea: blows on its upper end with an ebaby projectile

The main fragility of the Moes' storms and columnar bases is a decrease in the warmness of Bneogia, either from shells or from the top of the column to its tower. due to bending of the column. Coome Toto, used for marine single-bearing bases, pipes have large diameters and thickness

In this way, the well-known one-way drilling single support bases (MBOF) C2.33 are not very effective due to energy losses and low impact efficiency. The complexity and cost of working with such devices is quite high, while the reliability of the work of such MBOOs is not sufficient C31.
