Technical indicators of modern trawlers

Abstract

The article identifies the problem of the lack of up-to-date publicly available statistical information on the technical and economic performance of modern fishing vessels, including foreign mining vessels, which entails serious restrictions on the choice of a prototype, from which domestic authors are forced to use outdated indicators of ship designs built in the second half of the XX century. The methods of obtaining the necessary information using the open databases of the Global Fishing Watch organization are presented. The methods of the organization's work with information and the characteristics of some databases are described. The data has been processed for further use. According to one of the fishing criteria, the most effective trawlers of 2020 were selected. Thanks to the obtained statistics on the operation of trawlers, it was possible to obtain many technical indicators of the vessels ' operation: the operating mode, the structure and duration of the fishing voyage, the form of fishing organization, the balance of calendar time. As the statistics are processed, the results are analyzed. The observations made are described: about the round-the-clock operation mode; about the duration of storming; about the associated fishing. The obtained indicators were compared with the indicators of trawler factories in 1969. The necessity of continuing the study of the main technical and economic indicators of modern fishing vessels: income, expenses, profit is justified.
