Laboratory Test Predictions of the Cyclic Axial Resistance of a Pile Driven in North Sea Soils

Current international guidance recommends that cyclic loading effects are considered in pile design. However, methods for quantifying these effects on axial capacity are not well developed.

Dynamic and Cyclic Pile-Soil Response Curves for Monopile Design

Monopiles remain the most commonly used foundation for offshore wind turbines. Their design is governed by the lateral pile-soil response under operational and environmental loads that the turbine tower will be sub-jected to in its lifetime.

Engineering Behaviour of Mercia Mudstone for Offshore Pile Design

Mercia Mudstone deposits encountered offshore present a challenge for foundation design, due to the variable nature of the mudstone's physical and mechanical properties.

A Practical Constitutive Model for Offshore Foundation Problems Involving, Dense Sands in Partially Drained to Undrained Conditions

Despite significant advances in constitutive modelling within academia over the last few decades, the resulting advanced models are seldom used by practising engineers, particularly at the initial stages of design, due to their mathematical complexity, potential numerical instabilities, slow runtimes, and the often large number of model parameters required.

Borehole geophysics and hydraulic testing aids in determining geotechnical parameters for a nearshore cable tunnel in a fractured sedimentary deposit

Geotechnical design of tunnels requires a level of precision and accuracy in the determination of subsurface parameters that is more rigorous than most applications of geophysical logs.

Tethered BOP stacks: Performance and monitoring

Subsea wells present challenges for fatigue utilisation throughout the life of these high-value assets. New wells may be constructed at seabed locations where soil properties may be unfavourable or uncertain.

Evaluation of the ocean circulation for the Solomon Sea using the Regional Ocean Modeling System (ROMS)

The Regional Ocean Modeling System (ROMS) is a free-surface, terrain-following, primitive equations ocean model and it was implemented to perform a high-resolution 10-year hindcast study of Solomon’s Sea circulation patterns.

Effective harmonic analysis with spectrum filtering technique

A spectrum filtering technique has been introduced to improve harmonic analysis in this study. The impact of site characterization and physical processes have been examined to justify the necessity of applying the spectrum filtering technique following classic harmonic analysis.

Wave slamming impact on offshore wind turbine foundations

This study proposes a new parameter, the wave front steepness parameter, to better describe the wave slamming coefficient.

A novel approach to generating a hurricane database for the Gulf of Mexico based on numerical Weather prediction models

Accurate, reliable and cost effective hindcast databases have become essential tools for the design of offshore and coastal structures. Within the Gulf of Mexico (GoM), many databases exist, which cover operational wave climates, but very few of these fully resolve the complexities of Tropical Revolving Storms (TRS) in terms of both the spatial and temporal resolution.
