Collisions at sea are catastrophic events that can lead to loss of life, environmental damage and significant economic consequences. Collisions are most often the result of the error or negligence of at least one, and often more, officers (navigators, sailors) on the ships participating in the collision, that is, in 90% of cases the cause of the collision is the human factor. The human element is the most unpredictable factor considering that everyone has a different behavior and understanding, the ability of people to safely and effectively deal with the complexity, pressures, workload or difficulties of daily tasks and that, not only in emergency situations but also during daily routine , may differ. Therefore, the basis of the crew's success lies in their maritime education, especially the comprehensive training of commanders and officers. Education serves as the cornerstone of their competence, equipping them with the necessary skills to handle various situations at sea. Depending on their specific positions on board, each crew member acquires specific knowledge relevant to their roles during shipboard operations. The maritime industry has witnessed numerous col-lisions at sea that have led to significant consequences and valuable lessons for improving safety and preventing future incidents. Through case study analysis, research and industry insights, this paper has shed light on the multifaceted nature of human factors that contribu-te to collisions between ships. These factors range from lapses in judgment to failure to ef-fectively communicate intentions. However, the key lesson that emerges is that these human factors are not inherent weaknesses, but rather challenges that can be addressed through comprehensive strategies.
