The effect of soil type on the behaviour of a tolerably mobile subsea foundation Open
Tolerably mobile subsea foundations may be used to replace conventional fixed mudmat foundations for pipeline infrastructure and are designed to slide on the seabed along with the connected pipeline, in order to accommodate thermally induc…

Calibration of strain-softening constitutive model parameters from full-field deformation measurements Open
Many offshore geotechnical problems—such as cyclic T-bar penetration and lateral buckling of pipelines—are affected by the tendency of fine-grained soils to strain-soften due to remoulding. Careful calibration of the constitutive model par…

Low‐cost digital image correlation and strain measurement for geotechnical applications Open
Particle image velocimetry (PIV), or digital image correlation (DIC), is a widely used technique to measure soil displacements and strains in small‐scale geotechnical models. Arrays of single‐board computers (SBCs) produced by Raspberry Pi…

Observations of the Effects of a Clay Layer on Suction Bucket Installation in Sand Open
Suction buckets are becoming established as a viable foundation solution for offshore wind turbines. In sand, suction-induced seepage flow reduces effective stresses at the skirt tips, which decreases penetration resistance. However, layer…

Observations during suction bucket installation in sand Open
Suction buckets represent a viable solution as foundations for offshore wind turbines. Installation in sand is relatively straightforward, albeit with limited understanding of the resulting changes in soil state. This paper describes an ex…

The parkable piezoprobe for determining <i>c</i><sub>v</sub> and strength – modelling and interpretation methods Open
The parkable piezoprobe is a site investigation tool for measuring the coefficient of consolidation, in situ offshore, at shallow embedment depths. The device applies a similar bearing pressure to subsea infrastructure so it reaches a comp…

Enhancement of bearing capacity from consolidation: due to changing strength or failure mechanism? Open
Bearing capacity of shallow foundations is higher following preload (or self-weight)-induced consolidation because the soil strength changes, and perhaps because the failure mechanism changes. Previous studies have illustrated this effect …
