- Sam Stanier graduated from The University of Sheffield with an MEng (Hons) degree in Civil Engineering in 2007. Following this he joined the Geotechnical Engineering Group at The University of Sheffield as a postgraduate student, investigating the use of transparent synthetic soils and Particle Image Velocimetry (PIV) techniques to assess the failure mechanics of geotechnical structures non-intrusively. Upon award of a doctorate in Geotechnical Engineering in 2011 Sam joined the Centre for Offshore Foundation Systems at UWA.
- Key research
- Punch-through risk assessment for jack-up rigs - On arrival at COFS in 2011 Sam worked on the prediction of the performance of jack-up foundations (Spudcans) in multi-layered soils (largely sand-over-clay and clay-sand-clay stratigraphies). Punch-through of jack-up foundations – the so called crème-brulee effect where a strong thin layer above a soft thick layer of soil fails – is the single largest cause of jack-up loss worldwide. Sam and UWA-COFS colleagues and students Mark Cassidy, David White, Yuxia Hu, Dong Wang, Pan Hu and Shah Neyamat Ullah have extensively used the drum centrifuge at UWA in conjunction with large deformation finite element modelling (RITSS and CEL) to tackle the problem of predicting punch-through risk from typical site investigation data. The research has led to methodologies to predict the peak resistance during punch-through and the punch-through depth, which can be used for site-specific assessment prior to jack-up deployment.
- Offshore in-situ testing methods (RIGSS JIP) - Since 2014 Sam has been the lead researcher on the RIGSS (Remote Intelligent Geotechnical Seabed Surveys) JIP project funded by Benthic, Fugro, Total, Shell and Woodside ($1M AUD over three years). The JIP is developing novel tools for in-situ testing such as shallow penetrometers, free-falling penetrometers and in-situ scour erosion test devices (see www.rigss jip.com for further details). Sam’s research has focussed on development of the shallow penetrometers. These tools are designed to mimic pipelines and other shallowly embedded infrastructure and can measure soil strength, consolidation characteristics and interface friction properties - in a single test - at very low stress levels (<5 kPa).
- Image-based deformation measurement (GeoPIV-RG) - In 2015 Sam, along with co-authors Justin Blaber (Georgia Tech., USA), Andy Take (Queen’s University, Canada) and David White (UWA) released a new version of the popular MATLAB -based geotechnical image measurement software GeoPIV. The new version of the software – called GeoPIV-RG - allows the subsets of the analyses to rotate and deform leading to an order-of-magnitude increase in measurement precision over the previous generation of software. The software is currently being used in over 60 academic and consulting institutions around the world, by over 180 researchers. GeoPIV-RG can be downloaded for free at www.geopivrg.com.
