This paper elaborates on a model that was developed to predict the extent of pile run and velocity of pile and hammer during a drop fall. The model includes an approach that allows for assessment of effects from liquefaction during...

...), and for the near-field case (with mudmat) were estimated. Then, a bearing capacity analysis was performed in the same finite element program using the generated excess pore pressure stress field for the near-field case. The 2D SRA results showed that liquefaction (excess pore pressure ratio equal or greater than...

In addition to detailed cyclic plasticity models for describing progressive generation of pore water pressure, a number of experimental models have been developed based on results of cyclic triaxial tests. Such tests mostly considered isotropic...

Additional units from Petronas and ENI are under construction. The challenge with integrating elements of onshore LNG production...

... peoples as well as terrestrial flora and fauna. FLNG facilities also have the potential of serving multiple offshore fields over the life of the facility, thereby reducing the minimum size field that can be economically monetized. Three major decisions for FLNG topsides are pretreatment, liquefaction...
