Integrated hydrodynamic–structural analysis of very large floating structures (VLFS)

Extracting wave energy while reducing hydroelastic response of very large floating structures

“…This may result from its adaptability in handling complicated geometries of VLFS. For solving the fluid part, FEM may also be employed [81,82]. However, if FEM is used for the fluid part, it is difficult to satisfy the boundary conditions at infinity of the water domain because the water domain needs to be truncated.…”

Floating Structures as a Means of Safeguarding Coastal Urbanizations Sovereignty Against the Rising Seas : A Floating Community for Egypt

“…In 2005, Suzuki stated that the extreme malformation, movements, and the vibration impact on the VLFS might disturb the practicality of the VLFS as a floating runway when the cyclical loading caused by the waves motion could outcome in an exhaustion of the structural elements (Seto, Ohta, Ochi, & Kawakado, 2005). The extreme structural response may possibly also lead into sinking of the VLFS caused by the continuous and no stop flooding as well as drifting of the VLFS caused by a failure in the dolphin-fender system.…”

“…The extreme structural response may possibly also lead into sinking of the VLFS caused by the continuous and no stop flooding as well as drifting of the VLFS caused by a failure in the dolphin-fender system. More advanced hydro-elastic analysis has been done for a whole 3D VLFS, where it aimed to acquire the sufficient data needed about the deflections and stresses as to the secondary structural elements in the VLFS (Seto et al, 2005). The design proposal of a mooring system needs to study and resolve of wave drift forces activity on the VLFS.…”

“…Usually, here are two general methods for measuring the wave drift forces. Specifically, the near-field method it was founded on the direct pressure integration method and the far-field method founded on the momentum-conservation standards (Seto et al, 2005). Although both of there approaches can estimate the drift forces to be fairly good for a sole VLFS, on the other hand the far field method holds somehow a few boundaries in a scenario where two or more VLFS modules are designed to be positioned neighboring each other like in the situation of the FFSF.…”

“…Although both of there approaches can estimate the drift forces to be fairly good for a sole VLFS, on the other hand the far field method holds somehow a few boundaries in a scenario where two or more VLFS modules are designed to be positioned neighboring each other like in the situation of the FFSF. It is due to the far-field method which gives just the overall forces activity on every floating module, therefore the forces activities on separate modules might not be possibly achieved (Seto et al, 2005). However, the near-field method…”
