Improvement of the process of preparing cargo tanks of crude oil tankers for cargo operations ; Вдосконалення процесу підготовки вантажних танків нафтоналивних суден до вантажних операцій
The object of research is the process of inerting the cargo tank of an oil tanker. Issues related to improving the process of preparing cargo tanks of oil tankers for cargo operations are considered. It is noted that the efficiency of oil tanker operation, in addition to transport operations, is determined by the technologies used during the preparation of the vessel for receiving new cargo. One of such technologies is the inerting cargo tanks, which precedes any cargo operations. The study was aimed at improving the inert flue gas system by using a new technology for supplying jets of inert gas to the cargo tanks of an oil tanker. The main task of the research is to establish the degree of influence of the gas flow parameters (formed by the inert flue gas generator) at the entrance to the cargo tank on the nature of the change in air concentration in the entire volume of the tank. The final result of solving this scientific and applied problem is determined to be a reduction in the inerting time of cargo spaces of oil tankers. During the experiments, the supply of inert gas to the cargo hold was provided according to three technological schemes. The first contained only one jet source with an opening angle of 60°, which was located at the central point of the cargo tank bottom. The second contained four sources of inert gas jets, which were located crosswise on the tank bottom. The nozzles were installed diagonally in the centers of four identical rectangular zones of the tank bottom. Their opening angle to create a conical jet torch was 30°. The number of sources of inert gas jets of the third scheme was five. At the beginning of the inert gas supply process, four sources were used, which were located at the corners of the tank with an opening angle of 30°. When the initial value of the oxygen concentration in the air was reduced by thirty percent, the inert gas was supplied only from the fifth – the central jet source. It used a nozzle that creates a 90° cone opening angle of the jet torch. With the start of ...
