After performing relevant analyzes, including spectroscopy of samples of wood textures of the hull, the presence of hydrocarbon compounds and petroleum derivatives (bitumen) has been determined from FTIR analysis. Other essential analyzes in this study are microbial tests taken from samples. Analyzing the results obtained from the cross section of the samples, this ship was Russian, which was used to transport petroleum products with a wooden structure made of Russian pine (coniferous leaf).
