“…Further aspects of pile installation apart from penetration rate and energy efficiency (e.g. post-installation stiffness) are also of importance; the latter aspects of the present pile tests are discussed in other works [11,12]. During the installation phase of the experimental campaign, several piles with 𝑅 = 0.37 m (approximately 1:10 compared to offshore monopiles) were installed.…”

“…With increasing size of monopiles and reaching the capabilities of current design practices, it is essential that alternative methods with low environmental impact are developed for monopile installation. In view of these developments, the offshore industry is shifting its focus to vibratory techniques, such as the classical axial vibratory driving and the recently developed ''Gentle Driving of Piles'' (GDP) method [11,12]. However, the shift to the vibratory techniques introduces new challenges.…”

The field evaluation of pile-soil combination is a key step in the service life evaluation of pile foundation. However, due to the time-varying nature of pile-soil interaction, there is no efficient method to accurately analyze it. This paper introduces a health monitoring technique for assessing the state of pile-soil bond. The transient vibration of pile-soil coupling was measured by piezoelectric ceramic sensor. In the experiment, the different bond states of pile and soil were simulated by taking clay of different density as an example. A horizontal force is applied to the top of the pile, and the induced stress wave is detected by piezoelectric ceramic intelligent aggregate sensor embedded in the pile. At the same time, taking the artificial separation of pile-soil as an example, the binding state of pile-soil is analyzed, and the influence of different soil conditions on the pile-soil bonding characteristics is studied. An energy index for quantitative evaluation of pile-soil binding quality is proposed. Taking piles buried in two layers of soil with different densities as an example, the effects of soil with different densities on pile-soil bonding characteristics were studied. Experimental and numerical results verified the effectiveness of the proposed method. The three factors influenced the pile-soil coupling. The experimental and numerical results verified the effectiveness of the proposed approach and pave the way for an approach to directly judge whether there is separation between the pile and soil and evaluate the pile safety.

“…Due to the lower noise emission, there is an increasing interest in the investigation of the applicability of vibratory driving and alternative driving methods, such as "Gentle Driving of Piles" (Tsetas et al, 2020) amongst others, for the installation of monopiles for OWTs. It is, however, yet unclear if the current design practices for the lateral loading of the foundation can be applied to vibratory driven piles since the methods applied are based on experience from impact driven piles.…”

The influence of the pile installation by vibratory or impact driving on the response to subsequent cyclic lateral loading, as faced in the offshore environment, is investigated numerically. Largedeformation analyses of the pile installation process using the Coupled Eulerian-Lagrangian method considering partially drained conditions are performed. Following the installation, one million lateral load cycles are simulated using the high-cycle accumulation (HCA) model. The lower the hydraulic conductivity of the soil during driving, the higher the accumulation of lateral deformation when the pile is subjected to high-cyclic loading. The assumption of ideally drained conditions during pile driving results in a lower accumulation, in particular for the vibratory driven pile. Compared to the influence of the drainage conditions during driving, the influence of the installation method is found to be of less importance. While the vibratory driven piles tend to give less resistance to monotonic lateral loading for most conditions, slightly lower permanent pile head rotations after one million lateral loading cycles are observed compared to the impact driven piles.
