| Summary: | The reverance of the study is conditioned by the need of maintaining and upholding environmental standards and requirements in the field of trunk line transport, particularly at water services facilities. Currently used devices for containment and collection of spill products in water surfaces of rivers in case of accidents on underwater lines have a number of drawbacks: beginning with failures in the operation of booms, often caused by imperfections in the design (leakage, gliding of the product), and ending with the application limit due to seasonal changes (not only the state of surface water bodies, but also physical properties, characteristics of oil and petroleum products). In light of this, it is extremely important to improve the devices used and develop new boom systems. Furthermore, to achieve a greater effect, it is necessary to constantly improve the methods of calculating the parameters of the installation and the operation of such devices in the waters. The aim of research is:to present to broad public a new design of stationary all-weather booms with variable floatability - «Stabonza» and «Stabonza-Shelf», intended for prompt liquidation of the consequences of oil and petroleum products spills in underwater lines, production platforms and offload sea terminals. Additionally, to adjust the calculation parameters for setting the boom system to the set position. Methods. Methods of building mechanics (material resistance): integration technique of the differential equation of the curved beam axis in order to determine deflections and angles of rotation is used in the research. Results. The design and operation principle of the developed stationary all-weather booms with variable floatability - «Stabonza» and «Stabonza-Shelf», which are fundamentally different from those that exist today with high reliability and durability due to the integrity of the main elements, low cost of components and materials, and, first of all, deploying and bringing the system to its original planned state. The parameters ...
