There are many methods of laying pipelines through natural and artificial obstacles and constructions of such transitions.
The choice of a specific method (or design) in each specific case should be based on the consideration of the set of conditions of passage and requirements for the transition - technical, economic, environmental, etc. [1]
The experience of many countries, for example, Germany, Japan, Great Britain, proves that the cheapness of traditional laying of pipelines at transitions is an illusion, and the indirect losses from the construction of transitions by traditional methods are significant.
