The main research questions of this work are: which ship types and size classes are most vulnerable, how often the accidents of interest have occurred in the past, and whether the prevailing weather conditions during the accidents are comparable with those defined as“ad-verse conditions”in the Interim Guidelines. The methodology of the analysis comprised the following steps: 1) gather information on the accidents of interest, 2) screen the information to identify the cases that are more likely to have been caused by a lack of sufficient propulsive power, 3) identify the size classes for each ship type that seem most vulnerable to this hazard, 4) determine the frequency and possible temporal trends of the accidents of interest, and 5) determine the prevailing weather conditions.
