... ABSTRACT Accurate prediction of the structural response of flexible cylinder vortex-induced vibrations (VIVs) relies heavily on the accuracy of the acquired hydrodynamic coefficient database. Due to a large number of variables, the construction of systematic hydrodynamic databases from rigid...

.... It has been shown that the database could help to provide nonlinear characteristics of the vessel (Xu, et al., 2021). Although many previous studies have shown the possibility that machine learning can be a solution for real-time ship motion prediction, it is hard to confirm that those machine learning...

The method is tested for underwater operation of a deep-water work class Remotely Operated Vehicle (ROV); connected to surface vessel through...

... and standards. Understanding shaft friction in drill and grouted piles in rock is critical for design of offshore foundations in rocky seabed. This paper presents insight into shaft friction using a new database of shaft friction in rock by compiling from literature a comprehensive collection of 365 pile load...

... Abstract The Vortex-induced vibration (VIV) prediction of long flexible cylindrical structures relies on the accuracy of the hydrodynamic database constructed via rigid cylinder forced vibration experiments. However, to create a comprehensive hydrodynamic database with tens of input parameters...

... of wave, ship and internal liquid is decomposed into the ship–wave interaction problem and the compartment sloshing problem which are independently solved using the potential flow theory and the viscous flow theory, respectively. A database of wave load and sloshing load in a wide range of working...

...), and then the results are utilized for the corresponding computations of the reliabilities in accordance with the acceptable criteria by industry. The criteria of the structural reliability are introduced to assess if the damaged structures are still capable of operations. Once the simulation database is established...

...ABSTRACT ABSTRACT Experimental results of sloshing model test have been investigated by data mining in the database of Seoul National University. More than 540 terabytes experimental data have been accumulated for various cargo holds, vessels, environmental conditions, operational conditions...

... ABSTRACT In this study, we aimed to propose a method to search for evacuation routes not encountering a tsunami by constructing a database of tsunami arrival times considering the uncertainty of tsunami source by conducting inundation calculations of multiple tsunami sources. A database...
