Li, Qiang (author), Wang, Xinquan (author), Gavin, Kenneth (author), Jiang, Shengxiang (author), Diao, Hongguo (author), Wang, Kangyu (author)Extensive studies have been performed on the effectiveness of scour protection against scour erosion progression. But there is little research to date evaluating the effect of scour protection on vertical resistance behaviour of monopile foundations. This paper investigates the influence of scour protection on the vertical loading behaviour of...journal article 2024

Li, Qiang (author), Wang, Xinquan (author), Gavin, Kenneth (author), Jiang, Shengxiang (author), Diao, Hongguo (author), Wang, Mingyuan (author), Wang, Kangyu (author)Scour leads to the loss of soil around monopile foundations for offshore wind turbines, which affects their structural safety. In this paper, the effect of scour on the lateral behaviour of monopiles was extensively investigated using finite element analysis, and calibration and comparison were undertaken using centrifuge tests. Piles with three...journal article 2024

Baron, Edward A. (author), Mendoza Cabanzo, Carlos (author), Bento, Ana Margarida (author), Matos, Jose C. (author), Calçada, Rui (author), Gavin, Kenneth (author)Europe’s historic masonry arch bridges are culturally and economically significant, but their long-term safety must be ensured. Scour effects are the most common cause of collapse, so it is necessary to carry out structural assessments to mitigate the risk and prevent potential failures. In this study, a metamodel-based method was used to...journal article 2024

Tott-Buswell, Jacques (author), Prendergast, Luke J. (author), Gavin, Kenneth (author)Monopiles are the most common Offshore Wind Turbine (OWT) foundations due to their simplicity in design, fabrication, and installation. However, large new-generation turbines have led to significant changes in monopile dimensions, necessitating extensive finite element analyses and ground investigations to meet design requirements. While Cone...journal article 2024

Duffy, K. (author), Gavin, Kenneth (author), Korff, M. (author), de Lange, Dirk (author), Roubos, Alfred (author)Three driven precast, four driven cast-in-situ, and four screw injection piles were installed and tested in dense to very dense sand at a site in the Netherlands. Each pile was instrumented with two types of fiber optic sensors and tested under axial compression. Through these tests, a comparison could be made of how different installation...journal article 2024

Tolooiyan, Ali (author), Gavin, Kenneth (author), Dyson, Ashley P. (author)Accurate determination of the load-penetration behaviour of spudcan footings is vital in predicting the performance of offshore structures. Often, insufficient site investigation data is a limiting factor in assessing spudcan penetration, with the selection of suitable parameters typically derived from triaxial tests or Cone Penetrometer Test...journal article 2024

(author), Gavin, Kenneth (author), Giardina, Giorgia (author)Regional-scale assessment of the damage caused by earthquakes to structures is crucial for post-disaster management. While remote sensing techniques can be of great help for a quick post-event structural assessment of large areas, currently available methods are limited to the detection of severely-damaged buildings. Furthermore, remote...journal article 2024

Tolooiyan, Ali (author), Gavin, Kenneth (author), Dyson, Ashley P. (author)Offshore jack-up rigs are most commonly founded on large-diameter conical “spudcan” foundations, which are frequently designed using traditional analytical methods for shallow footings. This paper presents the design of a spudcan installed off the coast of Tunisia. The maximum penetration depth of the footing under the available preload is...journal article 2023

Sivakumar, Vinayagamoorthy (author), Fanning, Joseph (author), Gavin, Kenneth (author), Tripathy, Snehasis (author), Bradshaw, Aaron (author), Murray, Edward J. (author), Black, Jonathan (author), Donohue, Shane (author)This paper presents data from an initial development stage of an 'umbrella anchor' concept. The anchor can be pushed into sand deposit in a folded arrangement to reduce installation loads. When a pull-out load is applied to the mooring line, the anchor deploys to create a large embedded plate anchor. Physical modelling was carried out in...journal article 2023

Fanning, J. (author), Sivakumar, V. (author), Nanda, S. (author), Gavin, Kenneth (author), Murray, T. (author), Bradshaw, A. (author), Black, J. (author), Jalilvand, S. (author)One of the ways to install plate anchors in deep seabed is to drop the anchor system from the sea level and allow it to initially embed in the seabed under its own weight. Further dragging would cause the anchor to rotate and embed further into the seabed. There could be difficulties of getting the anchor plate horizontal or mooring line to...journal article 2023

This paper presents a systematic study to explore the applicability of deep learning techniques in foundation design. Firstly, a series of three-dimensional finite element simulations was performed, covering a wide range of embedment ratios and different...journal article 2023

Chen, Fuquan (author), Liu, Liyang (author), Lai, F. (author), Gavin, Kenneth (author), Flynn, Kevin N. (author), Li, Yida (author)Large-diameter monopiles are widely used as the foundation to support offshore wind turbines (OWTs) in shallow coastal waters. The benefits of small-to-medium diameter tapered piles have been reported in the past. The potential use of large-diameter tapered monopiles installed by impact driving to support OWTs is thus presented, and then...journal article 2022

Li, Q. (author), Gavin, Kenneth (author), Askarinejad, A. (author), Prendergast, L. J. (author)The influence of combined loading on the response of monopiles used to support offshore wind turbines (OWTs) is investigated in this paper. In current practice, resistance of monopiles to vertical and lateral loading is considered separately. As OWT size has increased, the slenderness ratio (pile length, L, normalised by diameter, D) has...journal article 2022

Gavin, Kenneth (author), Igoe, David (author)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. The offshore industry has been slow to implement ageing into practice because of uncertainty over the mechanisms...journal article 2021

Stipanovic, Irina (author), Bukhsh, Zaharah Allah (author), Reale, Cormac (author), Gavin, Kenneth (author)Aged earthworks constitute a major proportion of European rail infrastructures, the re-placement and remediation of which poses a serious problem. Considering the scale of the networks involved, it is infeasible both in terms of track downtime and money to replace all of these assets. It is, therefore, imperative to develop a rational means...journal article 2021
