Paper presented at the The Thirteenth ISOPE Pacific/Asia Offshore Mechanics Symposium, October 14–17, 2018
Paper Number: ISOPE-P-18-019
... ABSTRACT Soil permeability is one of key factors in the prediction of the wave- induced seabed response, which will directly affect the design of foundation around marine installations. Most previous studies in the field treated the soil permeability as a constant, although it depends...

... is the fluid density while s is the solid density; k is the Darcy s permeability; g is the gravitational acceleration. The Local RBF method is adopted to discretize the governing equations listed above. First, an approximation function (yi) which either stand for displacement or pore pressure in the u p...

Paper Number: ISOPE-P-14-101
... results indicate that the transient pore pressure is dominant in the upper part of the seabed while the residual component prevails in the lower one. Parametric studies are conducted to investigate the effects of the current velocity, the wave steepness, and the soil permeability on the pore pressure...

... the wave-induced pore pressure and stresses in marine sediment. The new boundary value problem was solved by the Legendre pseudo-spectral method numerically. Based on the new model, we investigate the effects of soil permeability, seabed bottom function on the pore pressures and vertical effective normal...

INTRODUCTION Natural gas hydrates are solid, ice-like crystalline materials that compounds of natural gas and water which can steadily existing under high pressure and low temperature conditions. The natural gas molecules are trapped in the cage-like structure...
