This study examined the impact of wind–wave misalignment on floating offshore wind turbines (FOWTs) in Irish waters, analysing average weather and extreme events, including hurricane conditions. Using ERA5 reanalysis dataset validated against Marine Data Buoy Observation Network measurements, results showed a satisfactory accuracy with an speed error −0.54 m/s strong correlation coefficient 0.92. Wind–wave was found to be inversely correlated (correlation coefficient: −0.41), minimum occurring approximately seven hours after change direction. The revealed that could exceed 30∘ during hurricanes, contradicting standard assumptions alignment under investigation highlighted western coastal areas, reach 57.95∘, while sheltered Sea regions experienced lower values, such as 23.06∘. Numerical simulations confirmed these events amplified side-to-side turbine deflections significantly. research underscores need incorporate effects into industry testing standards suggests current methodologies may underestimate fatigue loads by up 50%. work emphasizes improved design protocols for FOWTs complex marine environments highlights suitability climate analysis Ireland.

The offshore energy coupling system represents a promising direction for the future development of energy. Currently, wind-wave-hydrogen (OWWHECS) is most project application at current stage, with notable research gap in employment multi-criteria decision-making (MCDM) its site selection. Herein, this study, we innovatively use weighted hesitant fuzzy set (WHFS) method to improve technique order preference by similarity ideal solution (TOPSIS) and construct MCDM selection framework tailored emerging OWWHECS projects. Initially, comprehensive criteria reflecting unique aspects projects developed across various dimensions. Subsequently, WHFS employed gather criteria's evaluation data, followed best-worst entropy weighting assign both subjective objective weights system. enhanced TOPSIS subsequently utilized prioritize alternatives, thereby increasing precision rankings. Finally, validity proposed demonstrated through case study regions Bohai Bay Shandong Peninsula, China.

Abstract This study evaluates the technical feasibility of offshore subsurface formations for CO2 storage, Plume Geothermal (CPG), hydrogen and thermal energy storage. The goal is to understand how these processes behave in similar reservoirs impact water depth, geological reservoir properties, operational practices. behavior was studied using numerical simulations sensitivity analyses, focusing on thermoporoelastic stresses, pressure build-up, drawdown, injection rates, caprock integrity. results show that shallow depths delay fracture initiation, reduce stress-related risks, lead less heat loss cases involving extraction. Large permeability emerged as key factor maintaining storage integrity, with low-permeability showing increased risks fractures, especially during Operational practices also played a critical role. For instance, reinjection after shut-in or fully perforating particularly formations. Strategies such bottom-perforation use multiple wells reduced helped maintain Thermal shown be viable offshore, but its success depends selecting temperatures favorable injected minimize maximize recovery. Hydrogen although requiring larger pressures, proved feasible at evaluated rates no though higher could risks. Offshore hold significant promise multi-use platforms CPG These findings importance aligning conditions ensure integrity optimize efficiency. Future research would focus longer simulation durations, different settings, economic considerations deepen understanding systems.
