Roll damping decay of a FPSO with bilge keel

Ocean Engineering, 2014
The roll damping decay is investigated for a Floating Production Storage and Offloading (FPSO). For this purpose, a roll decay test of a middle section of FPSO with bilge keel is simulated by means of the numerical solution of the incompressible two-dimensional Navier–Stokes equations.

Development and Verification of Modeling Practice for CFD Decay Calculations to Obtain Roll Damping of FPSO

Volume 8: CFD and FSI, 2021
Estimates for roll damping are important input parameters for simulation studies on vessels operating at sea, e.g. FPSO mooring in waves, wind and current, workability and operability investigations, Dynamic Position studies, ship-to-ship operations ...

Most often instantaneous rotation center (MOIRC) for roll damping assessment in the free decay test of a FPSO

Applied Ocean Research, 2020
The previous study of Fernandes et al. [1] showed that rather than a fixed rotation center, the phenomenology can be better represented by the concept of a MOIRC. This study contributes to understanding Instantaneous Rotation Centers (IRC) and Most Often

A Study of the Roll Motion by Means of a Free Decay Test

Journal of Offshore Mechanics and Arctic Engineering, 2010
In this study, a method for the extraction of damping by tracing free roll decay is presented. For this purpose, in calm waters, a bulk carrier model is given a large initial roll angle and then released. Consequently, the roll motion is recorded.

Free Roll Decay Study of a Damaged Ship for CFD Validation

Volume 6: Ocean Engineering, 2011
Among many factors to be considered for higher safety level requirements, the hull stability in intact and damaged conditions in seaway is of utmost importance. Since the assessment of the damaged stability is complicated due to the highly non-linear behavior, it is widely acknowledged that computational fluid dynamics (CFD) methods are the only viable
