Automation of vessel hull technical condition assessment

Abstract

 Inland and mixed (river-sea) navigation vessels are characterized by limited periods of repair and restoration work occurring during the “cold” period of the year, significant age and lack of electronic documentation. These circumstances significantly complicate the defect detection of the vessel and the accompanying preparation of organizational and technical documentation. In connection with the course towards digitalization and the formation of a unified digital passport of the vessel, the task of automating the assessment of the technical condition of the hull is critically important. The key problem is the disruption of information flows: repair planning is carried out in conditions of uncertainty of the scope of work, and the assessment of the technical condition (defects) and the preparation of reporting documentation (stretch marks, tables for recording measurement results and recommendations for restoring the technical condition) are carried out manually or using outdated methods, in this case, the transfer of information between stages is carried out in most cases by “retyping” numbers. The work proposes an integrated approach to automating the planning and organizational preparation of ship repair, including three main areas: automated restoration of the digital basis, robotization of the defect detection process and integration of data into document flow with digital algorithmization of their processing. All of the above areas will not only improve the quality of defect detection, but also increase the efficiency of the vessel as a whole.
