Free Roll Decay of FPSO and FLNG Hulls With Bilge Keels Through Experimental Tests and CFD Simulations

Volume 1: Offshore Technology
The objective of present paper is to assess the roll damping characteristics of FLNGs and FPSOs. The roll damping characteristics are examined through the three prediction methods; 1) Ikeda’s empirical method, 2) experimental tests and 3) CFD ...

Nonparametric Identification of Roll Damping and Nonlinear Restoring Forces for a Ship from a Free Roll Decay Simulation

International Journal of Offshore and Polar Engineering, 2019
Roll damping and nonlinear restoring forces have an important influence on ship roll motion. To identify them from free roll decay behaviors, the models are generally assumed to be known a priori.

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 ...

Martensite decay during rolling contact fatigue in ball bearings

Metallurgical Transactions A, 1976
During rolling contact fatigue of ball bearings structural changes may occur below the raceway, in the region of maximum shear stress. A great number of 6309 type bearings were tested at two stress levels for varying numbers of revolutions, and the resulting structural changes in the inner rings were studied by optical and electron microscopy.
