...” is not suitable to predict the real pipe embedment; and soil stiffness plays an important role in pipeline behavior on the seabed. The illustrative examples and comparison with a previous work demonstrate the widespread applicability of this model. Moreover, the solution process of this model is easy and fast, so...

Porto; Diego Foppa; Cipriano José de Medeiros, Jr. This paper presents a numerical based study on the undrained load capacity of a typical torpedo anchor embedded in a purely cohesive isotropic soil using a three...

...M. R. Emami Azadi In the present study, the influence of various scenarios of supply ship collisions, namely, bow, stern, and also broad-side impacts on a jacket-pile-soil system, is investigated. In the previous study of ship impact on an eight-leg North-Sea jacket platform by Amdahl and other...

...M. R. Emami Azadi In the present study, the influence of spud-can-soil modeling and parameters on the reliability index of jack-up platform is investigated. Neka platform is studied as a case, which is a three-leg drilling jack-up type platform located in water depth of about 91 m in the Caspian...

...-type) boundary condition. Actually, we shall consider a nonlinear eigenvalue problem. Locally, at TDA, riser flexural rigidity and soil interaction play important roles and may affect the dynamic curvature. Extending and merging former analytical solutions on touchdown point (TDP) dynamics...

...Edward C. Clukey; Charles P. Aubeny, Assistant Professor,; James D. Murff, Visiting Professor, A plastic limit formulation was previously developed for estimating caisson uplift in cohesive soils under general conditions of vertical, horizontal, and inclined loading. The formulation considers...

... for the wave-induced seabed response in a porous seabed have been only concerned with the soil response after wave pressure penetrate into seabed. In this paper, employing a complex wave number, the whole wave-seabed interaction problem will be re-examined. Based on the new closed-form analytical solution...
