Research of the coupling effect of span-can penetration and environmental loads on piles

Abstract

Jack-up drilling platform is supported by spud-can foundations penetrated into the submarine soil layer for drilling new wells or work-over of existing facilities. When the jack-up drilling platform is positioned close to the adjacent platform pile foundation, the soil movement resulting from the spud-can penetration can induce significant loads on the piles. Especially when the working jack-up drilling platform suffers an extreme storm, the pile foundation strands the dangerous condition. The paper analysis the conclusions and disadvantages of the current studies, and then presents a new method for the coupling effect analysis of penetration pressing and environment load. Then this paper explains the solution by the example applied in the offshore practice.
