The current work presents a case study for the state-of-the-art multimodal risk assessment approach, which is especially appropriate environmental wind-wave dynamic systems that are either directly physically observed or numerically modeled. High dimensionality of system and cross-correlations between its primary dimensions components make it quite challenging existing reliability methods. goal this investigation has been application novel multivariate hazard methodology to combined windspeed correlated wave-height unfiltered/raw dataset, was recorded in 2024 by situ NOAA buoy located southeast offshore Greenland. Existing hazard/risk methods mostly limited univariate at most bivariate systems. It well known interaction windspeeds corresponding wave heights results multimodal, nonstationary, nonlinear with cross-correlated components. Alleged global warming may represent additional factor/covariate, affecting ocean related dynamics. Accurate necessary naval, marine, structures operate within particular offshore/ocean zones interest, susceptible nonstationary weather conditions. Benchmarking spatiotemporal efficiently extract relevant information from underlying field objective work. proposed evaluation presented assist designers engineers effectively assess structural risks ocean-driven wind-wave-related environmental/structural key result lies demonstration methodological superiority, compared popular copula approach.

ABSTRACT This case study presents state‐of‐the‐art, multimodal structural reliability and risk evaluation methodology, particularly suitable for naval architecture, transportation marine engineering applications. Existing methods do not easily tackle systems with a number of critical components higher than 2, while the advocated methodology has no limitations on system's dimensions, parts or components. The 4400 TEU container vessel's onboard measured deck panel stresses raw data, collected during numerous trans‐Atlantic crossings, was analysed. Risk ship hull damage caused by excessive whipping (slamming springing) wave loads, representing types highly nonlinear wave‐induced vibrations, are among primary safety concerns contemporary industry. It is often challenging to accurately forecast hot‐spot stresses, possessing complex nonlinear, nonstationary properties. proposed hypersurface method fully accounts large components, as well dynamic nonlinearities. Lab testing may be disputed, obtained measurements will depend biased incident properties model scales. As result, dataset, from particular cargo ship, operating in North Atlantic provides especially valuable insights into an overall vessel durability reliability. investigation aimed at providing generic state‐of‐the‐art enabling accurate extraction pertinent information about dynamics, e.g., derived sensor‐recorded time histories. Utilising failure, hazard risks effectively yet forecasted, based spatially distributed stresses. presented hazards systems, having virtually unlimited numbers principal/key made use full scale kindly provided Det Norske Veritas, Oslo, Norway (DNV), which commercially its own.

As the offshore wind energy industrial sector develops dynamically towards its economic viability targets, it is important to continuously improve structural design, while increasing output and minimizing operational repair downtime. Large horizontal-axis turbines (HAWTs) are already commonplace they in process of being designed on a larger scale, which challenging. Vertical-axis (VAWTs), where tilt axis rotation not concern, constitute an alternative HAWTs field for floating design. This case study presents hydrodynamic loads analysis failure risk assessment novel cross-flow vertical Wind Energy Marine Unit (WEMU) with large rotor The primary goal this research was assess reliability WEMU given realistic environmental conditions. Environmental wave acting torus semi-submersible pontoon during had been modeled numerically. Subsequently, assessed, utilizing state-of-the-art self-deconvolution extrapolation scheme. Reliability prognostic results cross-validated versus existing four-parameter Weibull fit method. To summarize, presented combines design recently developed latter can be practical engineering use contemporary turbine
