• Maxsurf Motion Panel Method Damping Matrix

    Hello, I am an honour student at Australian Maritime College, currently conducting research on ship motion at zero speed beam seas. I was playing around with analysis using panel method, and was trying to get a roll decay simulation result from my…
  • How to get the linear damping coefficient considered in time domain?

    I wanted to compare the damping coefficients considered in time domain against the coefficients calculated using BV NR 493 rules (attached). Can anyone tell me how to get the linear damping coefficients used in time domain? Otherwise, can we input the…
  • Damping of SPAR floating structure using heave plate

    Hi all, I really need some help with my undergraduate thesis. So, I've been analyzing the effects of heave plate in the keel of SPAR to motion response of the SPAR structure using MOSES, and experimental trials. so here is my question. As far as I know…
  • Damping

    When running a wave response analysis, what exactly is the damping value that should be input in the wvrinp file? Is it the damping ratio ξ (actual damping/critical damping) or the total damping 2*ξ ? And so, if we say that a structure has 7% damping…
