A series of incidents with exceptional container losses occurred during the winter season 2020-2021. The Joint Industry Project TopTier is initiated to address the loss of containers, with active participation of major stakeholders, to find ways to avoid similar incidents in the future. Initial results show that parametric rolling in following seas was especially hazardous. The TopTier JIP took inititive to distribute this Notice to Mariners. This document describes how container vessel crew and operational staff can plan, recognize and act to prevent parametric rolling in following seas. More explicit guidance on the hazard of parametric rolling in following seas is work in progress.
