N. Boukpeti, Auteur ; D. J. White, Auteur ; M. F. Randolph, Auteur |This paper considers a simple one-dimensional model of a submarine slide at a steady state. From equilibrium relations, the distributions of shear stress, velocity and strain rate across the slide thickness are determined analytically for two ra[...]

H. E. Acosta-Martinez, Auteur ; S. Gourvenec, Auteur ; M. F. Randolph, Auteur |Environmental and buoyancy forces impart overturning moments and potentially direct uplift to offshore foundation systems. Shallow skirted foundations are an attractive design solution, as negative excess pore pressures developed within the soil[...]

M. S. Hossain, Auteur ; M. F. Randolph, Auteur |Installation of independent-legged jack-up rigs in sea-bed sediments where a strong layer overlays weaker soil can lead to catastrophic ‘punch-through', with potential leg buckling or toppling of the unit. Although approximate methods of analysi[...]

M. S. Hossain, Auteur ; M. F. Randolph, Auteur |This paper presents results of large deformation finite element (LDFE) analyses that investigate the penetration response of deep-penetrating spudcan foundations in stratified soil comprising a strong clay layer overlying weaker clay. Such stren[...]

W. Chen, Auteur ; H. Zhou, Auteur ; M. F. Randolph, Auteur |The influence of the installation method on the soil flow pattern, resulting external radial total stress changes, and final external shaft friction after consolidation has been investigated for caissons in soft clay by means of centrifuge model[...]

H. Zhou, Auteur ; M. F. Randolph, Auteur |The influence of the shaft on the resistance of a ball penetrometer was examined using a large deformation finite-element approach. A range of ball–shaft diameter ratios between infinitely large (no shaft) to 1 were examined in terms of resistan[...]

H. E. Low, Auteur ; M. F. Randolph, Auteur ; T. Lunne, Auteur |It has been reported in the literature that net cone penetration resistance is normally higher than the penetration resistance measured using full-flow cylindrical (T-bar) or spherical (ball) penetrometers, and also that the ball penetration res[...]

R. S. Merifield, Auteur ; D. J. White, Auteur ; M. F. Randolph, Auteur |The as-laid embedment of an on-bottom pipeline strongly influences the resulting thermal insulation, and the resistance to subsequent axial and lateral movement of the pipeline. Reliable assessment of these parameters is essential for the design[...]

Z. J. Westgate, Auteur ; D. J. White, Auteur ; M. F. Randolph, Auteur |Reliable prediction of the embedment of untrenched subsea pipelines is of increasing importance as hydrocarbon developments progress into deeper waters, located further from shore. Pipeline design issues such as hydrodynamic stability, lateral b[...]

H. E. Low, Auteur ; M. Landon Maynard, Auteur ; M. F. Randolph, Auteur |The Burswood clay is a lightly overconsolidated and sensitive silty clay of high to extremely high plasticity. In two extensive characterisation studies, a wide range of in situ tests were carried out at the Burswood site, including full-flow pe[...]

M. F. Randolph, Auteur ; D. J. White, Auteur ; Y. Yan, Auteur |Axial pipe–soil resistance is an important aspect of deep-water pipeline design, since it influences the longitudinal and lateral buckling responses under thermally induced expansion and contraction of the pipeline. Experimental evidence has sho[...]

J. D. Murff, Auteur ; D. A. Wagner, Auteur ; M. F. Randolph, Auteur |Penetration of a pipe into cohesive soil is an important consideration in offshore pipeline engineering, especially as such penetration affects on-bottom stability of the pipeline. If the soil is described as a perfectly plastic cohesive materia[...]

M. J. Cassidy, Auteur ; C. Gaudin, Auteur ; M. F. Randolph, Auteur |Suction-embedded plate anchors (SEPLAs) have been developed to answer the growing need for anchors to withstand significant vertical loading. The concept combines the advantage of suction caissons (known penetration depth and location) and ‘drag[...]

M. D. Richardson, Auteur ; C. D. O'Loughlin, Auteur ; M. F. Randolph, Auteur |This paper describes a series of centrifuge model tests designed to assess the increase in capacity of dynamic anchors due to setup in normally consolidated clay. The tests involved measurement of the vertical capacity of 1:200 reduced scale mod[...]
