Abstract
Nowadays, in the present technical civilization there are numerous complex technical systems that may generate various hazards. Large transport units like ships can be considered as the most dangerous systems. Therefore, it is important to eliminate all possible hazards, especially for ship crewmembers. Destruction of ship structural components caused by vast corrosion is one of these hazards. Usually, its activity leads to a decrease of strength of ship structural components. In 2013 the Polish Classification Society carried out the five-year renewed survey of the tall ship POGORIA. During this survey, the PRS inspectors detected a damage in a form of the corrosion conic pinhole with considerable dimension situated within the lower part of the mizzenmast. Preliminary investigations carried out showed that the main reason of this damage was the occurrence of electrolytic corrosion originating from stray currents flowing between both the lower part of the mizzenmast and the cables charging navigational and radio equipment. This paper deals with backgrounds of the detected damage. In particular, the analysis of a damaged site and development of stray current corrosion have been presented.
