Hi members of gCaptain,
I am currently conducting a study on Parametric roll motions for my final year project at Plymouth University, the following link would take you to the questionnaire, it should not take more than 5-10 minutes to complete. Your time and effort will be very much appreciated, if you have any further question, please feel free to contact me at: parametric.roll.motions.study(at)gmail.com
Yeah, on the job training. I had never heard of parametric rolling before that and didn’t understand what was happening till I got home and started researching on the internet.
My relief had significant cargo damage next voyage due to heavy rolling and I was told through the grapevine it was while hove to in head seas.
I still haven’t seen anything official about parametric rolling but the latest version of the weather routeing software I got aboard shows areas where both synchronous and parametric rollling are a risk.
