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

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

(author), Gavin, Kenneth (author)The paper presents a risk assessment model, developed in the project oVERFLOw and further implemented in the project CROSScade, for determining the direct and indirect impacts of flooding hazards. As a consequence of flooding, transport infrastructure and flood protection systems can be significantly damaged and cause cascading effects on other...conference paper 2023

(author), Zhou, Hongpeng (author)Predicting the non-linear loading response is the key to the design of suction caissons. This paper presents a systematic study to explore the applicability of deep learning techniques in foundation design.

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

Duffy, K. (author), Gavin, Kenneth (author), de Lange, D.A. (author), Korff, M. (author)This paper describes axial load tests on three full-scale driven precast piles in the Netherlands. The piles were founded in dense to very dense river-deposited sands, a soil that is widespread across the Dutch North Sea sector. The deposit is characterised by cone penetration test (CPT) tip resistances of up to 90 MPa and offers a detailed...conference paper 2023

Duffy, K. (author), Gavin, Kenneth (author), de Lange, Dirk (author), Korff, M. (author)Stresses generated from pile installation are a critical component in understanding pile behaviour. These are known as residual stresses and in Delft, the Netherlands, the response of three driven precast piles founded in sand was measured using distributed fibre optic sensing as part of a series of full-scale static load tests. The...conference paper 2022

Askarinejad, A. (author), Wang, H. (author), Chortis, Giorgos (author), Gavin, Kenneth (author)The scour protection layers are usually installed around the monopiles to prevent the formation of scour hole. While extensive studies have been performed on the effectiveness of scour protection layer as mitigation measure, no study to date has been found to quantify the influence of scour protection layer on the lateral response of...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

Bascunan, S. (author), Kaltekis, K. (author), van Dijk, B. (author), Gavin, Kenneth (author)A joint academia-industry project, the Pile Soil Analysis (PISA) project, resulted in an empirical method for assessing the monotonic lateral loading response of large diameter monopiles. The method predicts four soil reactions, namely the distributed load and the distributed moment along the pile shaft, the pile base shear and the pile base...conference paper 2022

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), Askarinejad, A. (author), Gavin, Kenneth (author)The majority of offshore wind structures are supported on large-diameter, rigid monopile foundations. These piles may be subjected to scour due to the waves and currents that causes a loss of soil support and consequently decreases the pile capacity and system stiffness. The results of numerical models suggest that the shape of the scour hole...journal article 2021
