Abstract
The analysis of pipeline lifting and lowering operations is given depending on the effective weight and bending rigidity of the pipe, pressures on its walls, reservoir depth, concentrated lifting force. The change in water and gas pressures during lifting and the corresponding nonlinear term in the bending equation are taken into account. The simplest model for accounting for hydrostatic nonlinearity is developed. An insignificant effect of elastic nonlinearity on the bending of a gas pipeline is shown when the reservoir depth is limited. The regimes of controlled lifting force and controlled lifting boom are considered.
