EXPERT DIAGNOSTIC SYSTEM FOR HARBOR STRUCTURES

摘要

The hydraulic engineering department of FESTU since 1976 have executed a large amount of works on inspection of harbor structures in Vladivostok, Nakhodka, port Vostochny etc. (over 100 structures). The analysis of physical wear of moorings show, that the constant observations of its physical state and significant investments into renovation are necessary. The several developed blocks of expert diagnostic system on base of GIS, including it concept and algorithm are presented. The following items are discussed: 1. Formation ob database of normative documents in design, construction and exploitation of structures of Russia and foreign countries; 2. Development of new repair techniques decreasing the investments into repair works with quality improvement; 3. Development of processing technique of field data (including videos) allow to compare the data of the previous inspections of structures; 4. Expert diagnostic system for determination of common factor of wear of harbor structure using field inspection database; 5. Preparation of computer forms allowing to speed up the field data processing and statistical treatment, decreasing the cost of expensive diving works; 6. Effective management of port administrators on repairs, alterations and future inspections; 7. Formation of the attributive databank on current state of marine structures of Primorye ports that allows to carry out monitoring, strategic and flowing planning; 8. Development and renewal of the normative documentation on designing, construction, operation and repair of marine structures (including offshore structures) on the basis of the researches and inspection of the structure technical state. The developed expert diagnostic system is used for inspection of harbor structures of Primorye region by Hydrotex Ltd which have one of two licenses in Russian Far East on inspection of hydroengineering structures and also licenses on designing, repair and construction. Three officials of company have state certificates of port inspectors. The research directions of Hydrotex Ltd which associate the efforts of researchers from hydraulic engineering department of FESTU and researchers from other institutes (Zanegin et al., 1986; Bekker et al., 2000): 1. Application of new technical means and know-how in field measurements (thickness measurer, cross-section liner, devices of non-destroying monitoring, defect test machines, means of videoobservation and digital photo etc.) with GIS processing; 2. Computer processing, storage and analysis of the field data with a help of CAD/CAM; 3. Formation of a database on marine structures for the information system and expert diagnostic systems (geographical, hydrometeorological, geological etc., cargo structure and turnover, characteristics of moorings, actual state); 4. Analysis of remote sensing of Far-Eastern coast (ice, temperature, salinity, steel and concrete wear etc.); 5. Writing of reference literature for students and specialists on mentioned themes.
