This article analyzes some maritime accidents involving passenger ships that occurred in the Baltic Sea.
Existing forms of passenger transport by sea have been identified, and passenger-ship accident statistics in the
years 2003 to 2013 are presented. We discuss threats that may exist in passenger transport such as, technical,
operational and navigational risks, as well as threats caused by human error and bad weather. In the last part
of the paper, we analyze the cause and effect of selected incidents of passenger ships in the Baltic Sea, which
include the grounding of the ship MS Amorella, the Stena Spirit ferry collision with infrastructure, and the
collision of two ships, the MS Gotland with HSC Gotlandia II. The impact of the human factor on the safety
of passenger ships is also analyzed.
