Categorical Boosting (CatBoost) was validated as superior for predicting jet dynamics, enabling efficient optimization of nozzle diameter (<em>d</em>₀), exit velocity (<em>u</em>₀), and discrete layouts. A case study near Nanshan Harbor, China—where severe heat stress occurred in 2024 (Degree Heating Weeks, DHW &gt; 8)—revealed that the integrated PSO-DPSO algorithm improved cooling efficiency by 17.8–46.1 % compared to random layouts, identifying optimal parameters (<em>u</em>₀ = 0.20 m/s, <em>d</em>₀= 0.21 m) that balanced efficiency and thermal retention. Notably, the simulation-based results indicate that the optimized system reduced the DHW value during the study period from 1.83 to 0.45 in the coral region, corresponding to a 1.38±0.073℃ decrease in average temperature—below the threshold (DHW = 1) that induces visible coral stress.

However, the effect of depressurization and hydrate decomposition on fracture conductivity remains unclear. This study examines the performance of proppants in propping artificial fractures and monitors changes in fracture conductivity and proppant embedment depth during depressurization and hydrate decomposition. Firstly, the changes in fracture conductivity during closure pressure loading and hydrate decomposition were measured by quantitatively injecting pre-cooled methane gas using an API-standard fracture conductivity chamber specifically designed for hydrates. It was found increasing closure pressure to 7.5 MPa led to a decrease in fracture conductivity that was more than 6.9 times greater than that caused by slow hydrate decomposition. The main causes of this conductivity damage were proppant embedment and rearrangement, with rearrangement being the more significant factor. Notably, proppant embedment was more pronounced in hydrate reservoirs compared to other unconventional reservoirs. After the complete decomposition of hydrates, the embedment depth was measured using White Light Optical Profilometry, showing that at a low closure pressure of 7.5 MPa, the embedment depth reached up to 28 % of the proppant diameter. Fractures using 40/70 mesh proppants exhibited higher conductivity compared to those using 30/50 mesh proppants. Additionally, increasing proppant concentration increased fracture conductivity, primarily due to reduced embedment and increased fracture width. Different proppant concentrations displayed distinct mechanisms of conductivity damage: single-layer proppants saw a rapid conductivity decline due to proppant embedment, while multilayer proppants experienced significant reductions from proppant compaction. Seawater flow on the fracture surface further decreased conductivity by 20.68 %, mainly due to the softening and expansion of clay, which exacerbated proppant embedment. This study emphasizes the importance of closure pressure and proppant properties in maintaining fracture network permeability for long-term gas extraction in clayey-silt NGH reservoirs, providing key insights for optimizing marine NGH production.</div></div>","PeriodicalId":8261,"journal":{"name":"Applied Ocean Research","volume":"164 ","pages":"Article 104761"},"PeriodicalIF":4.4,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145010920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such pipelines may contain pre-existing defects, including fabrication- or operation-induced cracks. If an offshore pipeline with an initial defect experiences vertical movement due to upheaval buckling, the crack can propagate in the tensile stress region, leading to fracture. This study presents a numerical modelling technique using an eXtended Finite Element Method (XFEM) to analyze the initiation and propagation of tensile fractures in a post-buckled pipeline. Conventional fracture mechanics commonly employ damage initiation criteria based on maximum principal stress (MAXPS) or maximum principal strain (MAXPE) with fixed values. However, these criteria have limitations when considering crack-tip constraints (stress triaxiality and Lode angle) during the numerical analysis. A modified Mohr-Coulomb (MMC) fracture criterion is implemented in the finite element program, Abaqus, using a user-defined subroutine to address this limitation. The MMC criterion considers shear slip and ductility, providing a more realistic representation of ductile materials than MAXPS and MAXPE models. This study also examines the influence of various fracture parameters under different damage degradation models. The findings provide practical insights for assessing crack initiation and propagation in post-buckled offshore pipelines.</div></div>","PeriodicalId":8261,"journal":{"name":"Applied Ocean Research","volume":"163 ","pages":"Article 104759"},"PeriodicalIF":4.4,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144988837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Scaled hydrodynamic model tests were conducted to evaluate the pitch suppression effects under environmental loads (wave height, wave period, wind thrust) and structural parameters of FOWT (column-deck spacing, ballast mass, tower height). The results indicate that gyro stabilizers generate positive damping at wave frequency and negative damping at low frequency. Both damping components increase with the wave height and period, but positive damping escalates more prominently, achieving a 3-times enhancement in pitch reduction under wind-wave combined conditions. Wind thrust amplifies suppression effects until reaching a threshold (2.7 N). For the influence of structural parameters, larger column-deck spacing reduces positive damping at wave frequency while increasing low-frequency negative damping, leading to diminished overall suppression. Additional ballast mass weakens positive damping by 77 %, and tower height elevation slightly enhances the promotion effect of wind load on the active damping at wave frequency, due to increased pitch angular velocity.</div></div>","PeriodicalId":8261,"journal":{"name":"Applied Ocean Research","volume":"163 ","pages":"Article 104757"},"PeriodicalIF":4.4,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144933132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is typically achieved using solvers that employ the boundary element method (BEM), which relies on linear potential flow theory. Precise estimation of the sensitivity of these interactions is equally important for system-level applications such as design optimization. Current BEM solvers are unable to provide these sensitivities as they do not support automatic differentiation (AD). To address these challenges, we have developed a fully differentiable BEM solver, MarineHydro.jl, for marine hydrodynamics, capable of calculating diffraction and radiation coefficients, and their derivatives with high accuracy. MarineHydro.jl implements both direct and indirect BEM formulations and incorporates two Green’s function expressions, offering a trade-off between accuracy and computational speed. Gradients are computed using reverse-mode AD within the Julia programming language. As a first case study, we analyze two identical floating spheres, evaluating gradients with respect to physical dimensions, inter-sphere distance, and wave frequency. Verification studies demonstrate excellent agreement between AD-computed gradients and finite-difference results. In a second case study, we leverage AD-computed gradients to optimize the mechanical power production of a pair of wave energy converters (WECs). This represents the first application of exact gradients obtained from BEM solver in WEC power optimization. Both studies offer valuable insights into hydrodynamic interactions and advance the understanding of layout optimization. Beyond power optimization, the differentiable BEM solver highlights the potential of AD for offshore design studies.

This study aims to provide an original insight into this topic using a new dataset collected during an experiment carried out in real conditions at a field site in the southwest of France.

The experimental setup included an innovative wave impact measuring station composed of a self supporting structure equipped with a series of high frequency pressure sensors. The station measured the loads induced by overtopping flow impacts at the crest of an upper-beach dike. Additionally, the swash flow characteristics prior to each impact and the runup against the station were captured using synchronized video recordings, complemented by an array of pressure sensors deployed on the beach foreshore. The magnitude of the measured impact force ranges between 0.38 and 9.70 kN/m. A majority of the recorded events have a twin-peak signal shape similar to that observed in laboratory studies. The joint analysis of the vertical pressure distribution and of the synchronized video images also allows to highlight different impact phases, which align with results from previous downscale experiments. However, in contrast with existing laboratory observations, our measurements show that the force peak measured during the reflection phase, which follows the maximum runup, deviates significantly from the hydrostatic prediction. The greater the intensity of the force, the more pronounced the deviation. The analysis of the pre-impact flow properties suggests a relation between the maximum impact force, the overtopping discharge and the momentum flux, while the deviation from the hydrostatic prediction seems more related to the swash flow height.

Equipped with sensors measuring near-bottom current velocity, temperature, turbidity, and a digital video camera, the lander recorded six resuspension events. Suspended particulate matter (SPM) concentrations were derived from video analysis, revealing that smaller particles (0.6–6 mm) often dominated in number but contributed less to the total volume compared to larger particles (&gt;10 mm). Analysis of current velocity and temperature variations identified distinct resuspension mechanisms.

Four events resulted from up-slope propagating fronts caused by internal tide breaking. Down-slope events exhibited greater intensity than up-slope ones. Wavelet analysis of temperature data revealed sub-inertial frequencies during the resuspension events, associated with a dynamical regime known as the sub-inertial event and internal gravity wave (SIE-IGW) regime.
