ESTIMATION AND LONG-TERM PREDICTION OF UNDERWATER PIPELINING-CROSSING CONDITIONS

To improve the reliability of pipelines laid across rivers and streams, Russian researchers explored the possibility of estimating the actual conditions of underwater pipelines, both during construction and in operation. River bed and bank changes are responsible for exposing underwater lines, and the portions so exposed are subjected to the hydrodynamic action of the flowing stream and to damage by ice and other causes. The pipe may develop critical static and dynamic stresses, which under certain circumstances may cuase pipeline failure. Correct prediction of future bed and bank changes is a first step toward measures to ensure reliable pipeline operation. A method is suggested which estimates the present conditions of the line without opening up the trench. Other methods were developed for selecting the optimum route for a pipeline crossing and for determining the best repair method in a given situation.
