“…This system collects various operating data in real time and transmits them to land. It collects more than 80 types of data, such as the DHP, fuel consumption, water temperature, wind speed, and wind direction, which further include more than 40 types of data, such as course, heading, and ballast water (Shin et al, 2020).…”

“…To calculate the added resistance due to the ocean environment for the speed-power analysis of an existing ship, the accuracy and reliability of the input data must be reviewed first. In this section, the analysis results obtained based on onboard measurements (Shin et al, 2020) using an ultrasonic anemometer installed for accuracy improvement are compared with those obtained using the data extracted from the NOAA weather information based on the ship position and time to discuss the accuracy and availability of the data.…”

“…Lee et al (2019). Shin et al (2020) verified the validity of the SPA software program and analysis method by conducting the speed-power analysis of a 176 K bulk carrier and an 8,600 TEU container ship in operation. The authors constructed the mean stowage diagram of containers by analyzing the operating condition and obtained onboard measurement data by improving the data transmission system owned by the shipping company.…”

When performing simulations using computational fluid dynamics, the grid systems in the viscous boundary layer regions are important because the velocity and pressure change very rapidly in these regions. Especially for the turbulent flows, thin grids should be arranged densely in the direction perpendicular to the wall. In this study, the advancing layer method, which has been applied mostly to tetrahedral meshes, is applied to trimmed hexahedral meshes. To generate boundary layer meshes with non-intersecting grid lines near the wall boundaries having concave corners and narrow gaps, the directional vectors of grid lines and faces are smoothed, and the displacement vector fields calculated using the Laplace equation were utilized. Firstly, the details on the newly developed methods are introduced showing simple two-dimensional cases as examples. After applying the methods for a complex three-dimensional geometry to check its applicability and investigating the generated grid systems, the numerical simulations of propeller open water test for INSEAN E779A marine propeller were carried out by simpleFoam, one of the standard solvers of OpenFOAM. The computational results showed good agreement with the experimental results. Therefore, in conclusion, the developed advancing layer method is an appropriate method for generating boundary layer grids of a trimmed hexahedral mesh.
