Summary: This paper investigates the horizontal dynamic response of a pile embedded in unsaturated soil considering the effect of construction disturbance. Analytical solutions are derived using the Laplace transform and transfer matrix method. Parametric study reveals that the horizontal dynamic response of the pile head is significantly influenced by the range and degree of construction disturbance.

Summary: This paper proposes an FMEA-BN model for determining the inspection and opportunistic maintenance strategies of floating offshore wind turbines. The model utilizes a mapping algorithm to establish a mirrored Bayesian Network (BN) model based on failure mode and effect analysis (FMEA) structure, allowing for efficient consideration of common cause failures. By updating the failure probabilities of components using the BN sub-model, and utilizing the FMEA sub-model, this model suggests inspection and maintenance strategies for floating offshore wind turbines under various operation scenarios. The validation of the results demonstrates the effectiveness of the model in supporting real-time inspection and maintenance strategies determination for complex systems like floating offshore wind turbines.

Summary: In this study, a combined concept consisting of a floating offshore wind turbine and a wave energy converter is proposed and investigated. Different shapes of the wave energy converter were compared in terms of hydrodynamic performance and dynamic responses. It was found that the use of a concave-shaped wave energy converter resulted in better dynamic responses.

Summary: A multiphase constitutive model of hydrate-bearing sediment is established within a granular thermodynamic framework, considering the energy dissipation caused by hydrate dissociation and granular rearrangement at the micro level. This model captures the complex behavior of the sediment by incorporating the nonlinear expression of bonding stress, considering the relative velocities of the gas and liquid phases, and introducing the coupling effect of heat conduction.

Summary: The 15 January 2022 Tonga volcanic tsunami was a unique event where waves were created by a dual-mechanism generation process involving atmospheric pressure waves and eruption-induced water displacements. The study found that the maximum overall coastal tide gauge amplitudes ranged from 4.2 to 148.8 cm, while DARTs recorded maximum amplitudes of 3.6 to 21.4 cm.

Summary: Research has shown that the use of seawater-based microbial-induced carbonate precipitation technology can be applied in the construction of ocean islands and reefs. Different pH values of seawater-based UPB can induce calcium carbonate deposition at different times, with the strength and carbonate content of sand blocks cemented using the two-phase method being greater than that of the one-phase method.
