Assigning the size of the protected area during the TTS LNG bunkering operation
EDN: YZMAKE
Abstract
The work is devoted to the issue of assigning the size of a security area during the TTS LNG bunkering using the tanker-ship method. The initial data for the calculation scenario (leak location, equipment susceptible to damage, pressure and parameters of LNG inside the bunkering hose for liquid phase of LNG, dimensions of the hose for transferring bunker LNG) obtained during the risk assessment of this operation were proposed. When solving this problem, the LNG expiration rate was determined in two ways — according to the original methodology of Prof. V.A. Pavlovsky and the approximation from the IEC 60079-10-1:2021, which showed the same results. The results of the study can be used to determine the size of the security area when planning LNG bunkering using the tanker-ship method. The research materials of domestic and foreign scientists, as well as relevant guidance documents, are summarized and analyzed.
