This is a study of vessel accidents in harbors and harbor entrance areas. It addresses accidents involving at least one ship of more than 10,000 gross registered tons or a tug or towboat-barge array. The study period is fy 1972-76. The first objective was to identify patterns in accident causal factors, especially the coincidence of characteristics of the maneuvering situation and problems in task performance by the vessel controller. An additional objective was to evaluate the potential of proposed solutions to vessel control problems. The study involved controlled data-taking from the archive of accident reports maintained by the U.S. Coast Guard. A multivariate analysis design was employed to allow combinations of factors to be explored, since vessel accidents rarely can be attributed to a single cause.
