Abstract
We have performed calculations of stress-strain state of cable-stayed aerial pipeline crossing in the operation state and of the additional effect of the inspection gauge application. In order to assess efforts in the pipe and cable stays of the aerial crossing, we apply analytical solutions combined with numerical simulations using the 3D PipeMaster software system. This comprehensive analysis allows one to assess stresses in the critical zones of the crossing, as well as to develop recommendations on strengthening the structure of the aerial crossing before its in-line inspection.
