Ageing effects and CPT based design methods for driven piles in sands.
Igoe, David (2014) -
A Comparison of Soil Structure Interaction Models for Dynamic Analysis of Offshore Wind Turbines
Fitzgerald, Breiffni; Igoe, David (2020)This paper compares the dynamic response of an OWT structure where the below ground pile-soil behaviour is modelled using (i) the conventional API ‘p-y’ approach and (ii) the ‘PISA’ approach. A nonlinear aero-elastic code ... -
Examination of the reduction in natural frequency of laterally loaded piles due to strain-dependence of soil shear modulus
Igoe, David (2022)Society’s transition to low-carbon energy sources has resulted in significant expansion in offshore wind tech- nology. Most offshore wind turbines (OWTs) are founded on large-diameter steel tubular piles driven into ... -
A field investigation into the mechanisms of pile ageing in sand
Igoe, David (2021)The design of axially loaded piles has been an area of focus for the offshore industry in recent years. A number of studies report substantial increases in the shaft capacity of piles driven in sand, known as pile ageing. ... -
Field measurements of the base resistance of pipe piles in medium dense sand
O'Kelly, Brendan; Igoe, David (2008) -
Field tests using an instrumented model pipe pile in sand
O'Kelly, Brendan; Igoe, David (2010) -
Foundation damping for offshore wind turbines on monopile supports: a review
Igoe, David (2021)Today, an important challenge for offshore wind energy is to design efficient and reliable offshore wind turbines (OWTs). The overall damping of OWTs plays an important role in the design process as it limits the amplitude ... -
An investigation in axial cyclic loading on aged piles in sand
Igoe, David (2021)In recent years, there has been a significant push to develop optimized pile designs in the offshore industry, driven by the growth of offshore wind. One of the largest remaining uncertainties governing axial pile design ... -
An investigation into the use of push-in pile foundations by the offshore wind sector
O'Kelly, Brendan; Igoe, David (2013)This paper presents the results of a field test performed to study the effects of installation method on the load?displacement response of piles used to support the offshore wind turbines. An instrumented open-ended model ... -
PISA: New Design Methods for Offshore Wind Turbine Monopiles
Igoe, David (2017)Improved design of laterally loaded monopiles is central to the development of current and future generation offshore wind farms. Previously established design methods have demonstrable shortcomings requiring new ideas and ... -
Shaft capacity of open-ended piles in sand
O'Kelly, Brendan; Igoe, David (2011) -
Soil properties at the UCD geotechnical research site at Blessington
O'Kelly, Brendan; Igoe, David (2012) -
The effect of geotechnical uncertainty on the preliminary design of large diameter monopiles
ICASP14; Igoe, David; Reale, Cormac (2023)The offshore wind industry has evolved over the past decade with significant technological advances. These have been driven by the need for offshore wind energy to provide cost-competitive renewable energy. The economics ... -
The use of in-situ site investigation techniques for the axial design of offshore piles
O'Kelly, Brendan; Igoe, David (Taylor & Francis, 2012)
