... requirement of the wind load with respect to the safety, reliability and stability of jack-up platform in operation. Traditionally, the wind load acting on offshore structures is measured in wind tunnel tests, but with rapid development in Computational Fluid Dynamics (CFD) and ever-increasing computing...

... and CFD calculations for the maritime and offshore industry, good practice has to be executed in CFD modelling in order to benchmark with wind tunnel test result well. lng midstream oil & gas freight & logistics services gas monetization subsea system liquefied natural gas ship...

.... In this wind load calculation method, three (3) correction coefficients determined by wind tunnel test are brought in to improve the precision of wind load calculation. To find out the best solution with minimum power consumption of DP system, a nonlinear constrained optimization problem is built and solved...

... with a gap of 4m. The results are compared with the wind tunnel tests carried out within the Offloading Operability 2 JIP. The CFD code ReFRESCO is used. In this study, the simulations are carried out as a steady state problem and the k-ω SST model is used as turbulence model. In order to efficiently solve...

... is an experiment. The experiment is carried out by towing the ship in a basin. There are limitations due to the cost and time schedule in the basin test. The alternative of basin test is wind tunnel test. Hwang et al. (2016) and Huang et al. (2016) compared experimental results of basin and wind tunnel...

... tunnel. 1/60 scale model was used for basin test and 1/230 scale model for wind tunnel test. In order to validate and compare CFD method, STAR-CCM+ was used. The coefficients of current load are compared. The pressure and vorticity are analyzed to investigate the current flow around FPSO. It is noted...

... Abstract This study investigated the effects of turbulent wind profiles, level of details of topside structures and operation modes of gantry cranes on wind loads of a FPSO vessel. In order to do the research objectives, we performed a series of wind tunnel tests for a FPSO vessel model...

... was also estimated. Gap-protectors between containers stacks and a visor in front of upper deck were found to be most effective for drag reduction. Wind tunnel tests had been carried out to confirm the drag reduction performance between the base (without any modification) configuration and two modified...

... Abstract In this study, a steel modular tower and a multi-column tower proposed by RIST (Research Institute of Industrial Science & Technology) in Korea were subjected to wind tunnel test and CFD (Computational Fluid Dynamic) simulation; the steel modular tower has an octagonal cross...

... turbulence model and the three-dimensional steady-state solution are chosen to figure out the wind load. Compared with the wind tunnel test data, it indicates that the result difference between numerical simulation and test data is acceptable. The numerical result can be used as a support in the basic design...
