...-layered soil specifically in cases of penetrating through soft soils by simulating the possible squeezing accompanied by the back-flow phenomenon, which happens for the soft soil during the installation. The considered analysis criteria have been explicated. The results provided an effective expectation...

... Abstract For an open pipe pile installed on the North Sea to serve as the foundation for an offshore gas production platform the capacity was determined in various ways. First the Cone Penetration Test data obtained at the location were used to simulate the vibro driving process...

... corresponding to the Garn Formation base. After the productivity results from Z-3-H well came in at the low end of expectations, it was evaluated and decided to change the well profile of the Z-2-H well from vertical reservoir penetration to a horizontal profile; to have two penetrations with a minimum of 150m...

... Abstract A computer program has been developed to simulate the landing of suction piles on the seabed. The procedure is based on the dynamic analysis procedure outlined in DNVGL-RP-N103 ( DNVGL 2017 ) and calculates the pile motion as it penetrates the soil using a time integration scheme...
