VISUAL INSPECTION OF THE BLIND AREA OF A RIVETED VERTICAL TANK FOR STORING PETROLEUM PRODUCTS

A brief analysis of the requirements of the regulatory literature of the early 20th century on the design of vertical steel tanks is carried out. The technical characteristics of a vertical riveted steel tank, built in 1934 in the south of the Republic of Belarus, intended for storage of diesel fuel, are given. The article contains images provided to illustrate the current state of the cobblestone-reinforced blind area of the reservoir under study. As a result of the visual inspection surface defects of the concrete coating of the reinforced blind area of the tank were revealed, as well as some inconsistencies with the requirements of the current regulatory documentation. The conclusion is given about the relevance of conducting a study of the possibility of using blind area device technologies developed at the beginning of the XX century using modern building materials while meeting the requirements of modern regulatory documentation.
