PECULIARITIES OF INERTIZATION OF CARGO TANKS OF GAS CARRIERS DURING TRANSPORTATION OF FLAMMABLE SUBSTANCES

Abstract

The peculiarities of processing cargo tanks of gas carriers during the transportation of flammable substances are considered. It was determined that the most reliable way to prevent fires and explosions in cargo tanks is their inertization. Methods of inerting cargo tanks of gas carriers are given. The analysis of the main technological operations directly related to the process of transporting flammable substances, namely inerting, degassing, vacuuming, was performed. Charts are provided for determining explosive concentrations of mixtures of various cargoes with oxygen. An analysis of the main features of the following loading methods was performed: loading with return of cargo vapors, loading without return of cargo vapors, loading from another ship, loading of chemical products. It was determined that all technological operations for the reception, transportation and delivery of liquefied gases as cargo transported by gas carriers must be performed with strict compliance with the conditions that ensure their safety, as well as taking into account the requirements of suppliers and customers of these cargoes.
