Methods and models of complex diagnosis of seaport reconstruction-expansion on the example of Poti Port

The monograph discusses the systematic provision of complex diagnostics of berth facilities in the seaport and the development of modeling methodology to determine operational reliability, strength, and stability, considering local conditions.

Various comprehensive studies are conducted to address the challenge of developing seaports within spatial-territorial and economic constraints, leveraging and adapting foreign experience. The issue remains pressing for each old seaport, which has its unique characteristics, requirements, and limitations for development.

The relevance of the research topic and the particular importance of the monograph stem from the need to address port development on a scientific basis. Currently, there are no recommendations on the methods and models of port development organization and the establishment of logistics service systems for developing ports. However, the diagnostic methodology, organization methods, and typical logistics service models predetermined the research's direction and content.

The research aims to create conditions for the growing cargo turnover within limited spatial and territorial resources available at seaports in Georgia's current stage of development, which is achieved by the systematic provision of the use of complex diagnostic methods of responsible berth facilities in the port and development of modeling methodology, to determine the reliability, strength, and stability of their operation, taking into account local conditions.

The object of the study is the Poti Port, the construction of the breakwater (mole) and the supporting walls of the berth and fender structures, and the organization and management of the technological process of port expansion and reconstruction. A partial approbation of the research results was carried out in developing the port development organization model, including the diagnosis and reconstruction of the breakwater, retaining walls, and rubber fender structures.

The research presented in the monograph was carried out based on the system approach, management theory, organization theory, and logistics theory. The theoretical and methodological basis of the research is the following methods and models: the systemic and structural analysis; Complex diagnostic methods such as non-destructive testing, geotechnical, topographic, bathymetric, underwater ROV, and side scan sonar methods; Wave modeling methodology and management of technical diagnostics based on fuzzy theory.

Using the methodology proposed in the paper, detailed diagnostics of the Poti Port berth and mole structure and long-term observation results determined the berth's expansion-deepening, ways to restore the mole structure and extend the reliable operation period.

The monograph consists of 7 Chapters, an Appendix, and Literature. The importance of its publication is very significant for scientists working in the direction of hydrotechnical structures, for doctoral and master's students, and for the development of the field in Georgia in general. The book is published with the support of «Shota Rustaveli National Science Foundation of Georgia,» the «Grant number SP-23-663».
