October 2009 was colder than a normal; the ice began to meddle in the beginning of November in the innermost bays. As winter progressed the ice became thicker. The reason for the problem was a strong north-north-westerly wind that made the ice to break up. The ice drifted away and then packed into very rough ridges. The main question was what factors caused several vessels fasting on the Baltic ice 2009/2010 and what aids are considered the most reliable to use for ice navigation. The question was what factors caused several vessels to get stuck in the Baltic ice, and what resources are considered to be the most reliable for ice navigation. To investigate the phenomenon why so many ships got stuck in the ice the current winter the study is designed as a case study. To get a substantial collection of data in this study a qualitative interview method was used as primary selection and literature was used as secondary selection. This report is made by semi-structured and unstructured interview methods. The study includes four interviews with representatives from the Maritime Administration, Swedish Meteorological and Hydrological Institute (SMHI), Rederi AB Transatlantic and a researcher from the University of Gothenburg. The report declares that winter during the period of 2009/2010 was harsh with great amounts of ice combined with unpleasant wind. This resulted in tough conditions for engaged vessels. SMHI did also miss a forecast report which may have resulted in some of the ships that got stuck. It also appears that less ship would have got stuck if they had chosen the Sandhamn fairway. The new project MONA LISA on ICE is also mentioned as the potential future for ships. The report also shows that the role of ice breakers is crucial for the shipping segment during winter season at the Baltic Sea, and that shipping companies have potentially become better at looking after their pilot certificates. SMHI has together with the Swedish maritime authority succeeded to build a network of observations placed on the ice breakers, which gives a more accurate result. Lastly, it is worth mentioning that the Swedish maritime authority has become better at communicating with shipping companies who regularly sail the Baltic Sea, and that the building of more ice breakers would be a positive development for the environment.
