Ocean mining activities have been ongoing for nearly 70 years, making great contributions
to industrialization. Given the increasing demand for energy, along with the restructuring of …

The paper presents an overview of recent developments in geotechnical analysis and
design associated with oil and gas developments in deep water. Typically the seabed in …

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 T-bar penetrometer is extensively used in offshore field investigation and laboratory
testing to evaluate the undrained shear strength of soft clay because of its reliability and …

The paper outlines the processes that determine pipeline embedment in softsediments
typical of deep water, and describes quantitative methods forassessing the contribution to …

Offshore developments for hydrocarbon resources have now progressed to water depths
approaching 3000 m, with geotechnical design increasingly focused on soft sediments in the …

This paper summarizes best practice cost-effective geotechnical design of high pressure
high temperature (HPHT) pipelines, with an emphasis on HPHT lines in deep water, that are …

A ball penetrometer provides an efficient method for accurately assessing the undrained
shear strength of soft marine clays. However, evaluating the undrained shear strength in the …

The significant influence of the riser-seabed interaction on the fatigue performance of steel
catenary risers is now widely accepted. Most design, however, is still carried out using linear …

The interaction between the seabed and unburied pipelines is one of the key uncertainties
associated with deepwater and/or high pressure, high temperature (HPHT) pipeline design …
