Correlation leak detector for control of underwater pipeline leakproofness
The correlation method and the instrumentation of detection of leakproofness on underwater pipelines from a pond surface is observed. The appraisal of sensitivity of a correlation method is made. The factors influencing accuracy of localisation of a method are comprehensively researched. It is gained, that having acceptance alternators over a fulcrum of the tubing with accuracy ±1m, and using echo sounders for depth gauging it is possible to ensure localisation of leakage with accuracy not worse ±0,5m.Technical characteristics of the designed instrumentation and effects of its experimental testing services are reconciled.
