Design practice in offshore geotechnical engineering has grown out of onshore practice, but
the two application areas have tended to diverge over the last thirty years, driven partly by …

The pile leg-mat foundation is a novel composite foundation designed for jack-up offshore
platforms. The seismic response of such foundations in sandy seabeds is an issue that …

In this study, an experimental apparatus was designed and set up a in laboratory to observe
the vertical submerged jet scouring of cohesive beds. The critical conditions for the onset of …

The extraction of spudcan foundation in clay can often be difficult and time-consuming
considering the large pull-out force required to overcome the breakout resistance. This is …

The paper presents an overview of the recent contributions of centrifuge modelling to the
understanding of soil–structure interaction and the development of design and predictive …

In dredging, high pressure water jets are commonly applied to assist the mobilization of soil.
This work considers the excavation of cohesive soil. The key objective is to predict the …

In this paper a visco‐hypoplastic model, which can describe viscous behavior including
creep, relaxation and rate dependency of cohesive soils, is implemented in the form of a …

Retrieval of jack-up rigs at the end of their operations is common practice in the offshore
industry, notably to move the rigs to another drilling location. In some cases the process is …

For a jack-up rig installed in cohesive soil, assessing the extraction force is critical to ensure
the safe and successful retrieval of each spudcan footing. The extraction force depends on …

The effects of consolidation under a footing are generally viewed as beneficial due to the
resulting increased capacity. Consolidation may also be actively sought because it …
