... to study the spudcan-soil interaction. The model determines the minimum penetration depth and corresponding bearing capacity to ensure operational safety. The predicted penetration depths using the American petroleum Institution (API) and China University of Petroleum (CUP) theoretical models show errors...

... and numerical analysis results for a finless torpedo anchor. The comparisons showed that the advanced algorithm is able to (i) increase the accuracy of capturing frictional resistance profile along the penetration depth and hence the final tip embedment depth significantly, and (ii) reduce the computational...

... is an important aspect of cable burial risk assessment. There are several variables that influence the penetration depth of an anchor, including the soil type and the characteristics of the anchor (mass, fluke length, and fluke angle). This tool uses a single model to cover different vessel types, and the factors...

Spudcan penetration and extraction will result in additional lateral loads on adjacent piles. The effects of spudcan penetration on pile foundations of the adjacent jacket platform should be evaluated...

Recently, due to the enlargement of the structure load, the utilization of small piles diameter is reaching the limit that causes the increasing of the penetration depth...

... was of crucial importance to the simulation result. When the reef penetrates the bottom of the ship, the failure of the girders occurred firstly, followed by outer bottom and finally the inner bottom. The damage opening size was closely related to the shape of the reef and the penetration depth. The high stress...
