... and torque installation requirements necessary for offshore applications are large and must be reduced. By using centrifuge and Discrete Element Method (DEM) modelling this work demonstrates that the geometry and installation of helical piles can be optimised to reduce those installation requirements, while...

.... They aim to predict how the jack-up vessel's spudcan footings will penetrate the seabed when vertically loaded during installation. A typical LPA will involve derivation of a load-penetration relationship for a given footing geometry and a given set of soil conditions. Subsequently, considering the vessel...

... ABSTRACT: Pile driveability predictions require information on the pile geometry, impact hammer and the soil resistance to driving (SRD). Current methods to predict SRD are based on databases of long slender piles and have been shown to provide poor predictions when applied to geometries...

... to withstand lateral (and upheaval) buckling load coming from the pipeline. The available solutions for lateral resistance have been developed for buried pipelines under a flat seabed, and consequently do not take account of the geometry effect relevant to rock berms. They have also been mostly developed...
