摘要：

The acoustic channel calculation was carried out for possible propagation paths of acoustic emission (AE) waves along a steel vertical vessel (SVV) bottom. The calculation is based on the theoretical and experimental study of the main regularities of Lamb waves propagation in plates. The losses in the acoustic channel were evaluated. A case was considered when the SVV bottom is made of low carbon steel. It is found that at large distances from an AE source, the losses are essential which are caused by Lamb waves divergence in a plate and Lamb waves reflection and transformation at welded joints.
