The unsaturated permeability coefficients are often used to solve geotechnical problems associated with unsaturated soils. But it is very difficult to measure. However, the unsaturated permeability coefficients can be predicted by the Soil-water Char

In this paper, finite element (FE) analyses are performed with the commercial software Abaqus to investigate the turbidity-flow-induced behavior of a pipeline crossing the bottom of a deep-water canyon. A general hybrid geotechnical-fluid dynamics ap

In recent years the residual curvature method (RCM) has been used to provide buckle initiators to control and mitigate the global buckling of pipelines. Through the appropriate planning of these controlled buckles, an acceptable design of the pipelin

The interest in the adequacy of shallow foundations to withstand the forces in the subsea realm is growing. Subsea structures such as PLETs and PLEMs often experience significant torsion loads in addition to vertical, horizontal and moment loads whic

This paper investigates High Pressure and/or High Temperature (HPHT) design of a pipeline across an escarpment with significant seabed undulations and elevation change from drill center (DC) to riser touch down point (TDP). The pipeline has a tendenc

Abstract The interest in the numerical modeling of a deepwater pipe-in-pipe system (PiP) at a free span location is growing. In a free span, the inner pipe bends substantially due to internal pressure and temperature and possibly contacts the outer p

Abstract High pressure/high temperature (HP/HT) pipelines may significantly expand and contract longitudinally during operational heating and cooling cycles, resulting in global buckle formation at naturally occurring locations with high out-of-strai
