Steamship roll risk estimator – update

Steamship Mutual has notified members that there had been a further update to its earlier notification “Parametric Rolling IG Circular – Roll Risk Estimator”

The Marine Research Institute of the Netherlands (MARIN) has released an updated Roll Risk Estimator Excel Sheet (V1.3) and has reported that this latest version of Risk Estimator “contains a bug fix in the risk area prediction of parametric roll in (near) head seas, causing some drawing errors in the (polar) contour plots”.
