  22. Topicality of the problem of underwater crossings of trunk pipelines 1 1 2 2 • Underwater crossings of trunk pipelines through water obstacles are industrial hazards and complex natural-technical objects • Geophysical monitoring of underwater crossings of trunk pipelines facilitates efficient and reliable planning of repair and maintenance operations at the crossings and leads to improved safety and reduced costs for ensuring their safe exploitation 3 3 3 4 4 5 5

  23. Types and tasks of investigations at underwater crossings of trunk pipelines 1 1 Main types of investigations at underwater crossings of trunk pipelines: Monitoring of technical condition of underwater spans of trunk pipelines (planned inspections of underwater spans of trunk pipelines)Technical supervisionof repair operations at the crossingsEngineering surveys for crossings under constructionGeomorphologicaland geotechnical investigations in rivers(for the evaluation of the impact of fluvial processes on underwater spans of trunk pipelines). 2 2 3 3 3 4 4 5 5 Monitoring tasks: • Determination of the conditions of occurrence of inverted siphons in the bottom soils, identification of problematic areas, first of all,denudation and sagging of siphons, control of condition of pipe insulation (identification of leakage of cathodic protection current), efficiency of cathodic protection of siphons, monitoring of bottom relief and fluvial processes, identification of objects on the bottom, which are unfavourable or hazardous for pipelines (steep slopes, escarpments and wrecks), forecasting of changes in the condition of the underwater crossing for the period of one year and for a longer period. Tasks of technical supervision: • Control of quality of executed underwater technical operations in accordance with the requirements of the approved project;acceptance ofintermediate hidden works, the control of which becomes impossible during the execution of subsequent operations.

  25. Key role of CSP method 1 1 2 2 • Determination of horizontal and vertical position of pipelinesDirect surveying of denudations and sagsDetermination of height of denudations and sags Identification of hazardous or unfavourable near-bottom objectsInvestigations of the geological section, identification of the bottom of moving river drift 3 3 3 4 4 5 5

  26. Method of metal magnetic memory 1 1 The method of metal magnetic memory (MMMM) is based on the recording and analysis of the distribution of intrinsic magnetic stray fields, occurring in products and equipment in the zones of concentration of stresses andmetal defects. • The latest method of non-destructive testing, developed by Limited Liability Company “Energodiagnostika” for the inspection of onshore sections of pipelines, is being tested By Closed Joint Stock Co. “DPT” with the purpose of subsequent introduction in the practice of regular inspection of underwater pipelines. 2 2 3 3 3 4 4 5 5 • Advantages of MMMM The utilisation of MMMM does not require any special magnetisers, because the phenomenon of magnetisation of the equipment units and constructions during their operation is used;the locations of concentration of loads, unknown earlier, are identified during their control;there is no need to clean metal or prepare the controlled surface in any other way;the utilised equipment is small-sized and has self-contained power; • the velocity of the control in situ reaches 100 m/hr and more.
