CFD analysis on vertical motion of a full-scale floating jetty

A floating jetty often experiences several vertical motions i.e. heave and pitch motion responses due to harsh environmental condition. This inherently makes discomfort to everyone during berthing on a floating; and even it potentially leads to loss of life due to falling down into the sea. A preliminary analysis using Computational Fluid Dynamics (CFD) simulation is necessary to be conducted to ensure users safety. The CFD analysis focused on the interaction between wave motions and the floating jetty and its effects on the vertical motions. The vertical motions of floating jetty were quantified by the Response Amplitude Operators (RAO). Several effects due to variation of wavelength (/L) have been studied. The CFD results revealed that the lower wavelength (/L2.25) resulted in the increase of the heave and pitch motion amplitudes proportionally. However the subsequent increase of wavelength (2.25/L) has given results to less heave and pitch motion amplitudes. In general it is shown that the vertical motion characteristics of the floating jetty predominantly depend on wave properties.

Abstract

A floating jetty often experiences several vertical motions i.e. heave and pitch motion responses due to harsh environmental condition. This inherently makes discomfort to everyone during berthing on a floating; and even it potentially leads to loss of life due to falling down into the sea. A preliminary analysis using Computational Fluid Dynamics (CFD) simulation is necessary to be conducted to ensure users safety. The CFD analysis focused on the interaction between wave motions and the floating jetty and its effects on the vertical motions. The vertical motions of floating jetty were quantified by the Response Amplitude Operators (RAO). Several effects due to variation of wavelength (/L) have been studied. The CFD results revealed that the lower wavelength (/L2.25) resulted in the increase of the heave and pitch motion amplitudes proportionally. However the subsequent increase of wavelength (2.25/L) has given results to less heave and pitch motion amplitudes. In general it is shown that the vertical motion characteristics of the floating jetty predominantly depend on wave properties.
