Query – Simple Modelling of FPSO Vessel Rocking?


I’m curious whether anyone bothers to model the roll of a FPSO inside a process simulation package.

  1. I know that you can build vessels where you insert baffles to minimise the sloshing of liquids (does sloshing approximate to a simple harmonic motion system?), and Hysys allows for re-entrainment in the outlet (is there a simple formula which can approximate this?).
  2. Does a properly built vessel dampen the sloshing effect such that it’s not worth even thinking about vessel roll? What’s the largest vessel roll anyway?
  3. You can simulate the sloshing using computational fluid dynamics, but is that overkill?

Your answers and pointers would be interesting

    CDS done it with a sloshing effect on FPSO separators.
