The natural gas industry, as well as other industrial activities, is not free from accidents, which can cause serious consequences to the integrity of people and properties. For this reason, it is necessary to develop studies to determine what are the possible causes of LNG leakage during the loading or unloading operation. This paper aims to determine the reliability of the Cargo control system electric power supply system applying Markov Chain technique. This reliability modeling tool is used because the system consists of several components in passive parallel. Based on the reliability analysis maintenance recommendations are proposed aiming at reducing system failure probability. The method used in this paper is divided in three steps. The first step consists in carrying out a study to identify what are the components that are part of electric power supply system. The second step involves the reliability analysis of the electric energy supply system. Finally some maintenance recommendations are presented aiming at reducing system failure rate. This analysis is used for the analysis of a LNG carrier operating in a Brazilian harbor indicating the most probability failure modes of this system and the most suitable maintenance actions to avoid them.

The purpose of this work is to develop a multi-agent model of an integrated energy supply system in the AnyLogic simulation software and to conduct a research on the operation and interaction of objects in this system using the obtained model. A multi-agent approach is proposed to study integrated energy supply systems as it enables to carry out a detailed research of interaction and coordination mechanisms of various elements and subsystems (energy sources, transport subsystems, active consumers, etc.) of the object under investigation. The model is implemented in AnyLogic simulation software that supports designing, development and documenting of the created models, carrying out computer experiments, parameter optimization according to some criterion that enables visualization of the mechanisms of interaction and connection between the agents. A multi-agent model of the integrated power supply system has been developed. Agent state diagrams that take into account the operation of its elements have been created and the principles of their interaction and coordination have been analyzed. The structure of the developed model of an integrated power supply system contains four types of agents and connections between them. An experiment has been conducted on the basis of the developed model, in which the optimal solution was found for energy supply of consumers. The results of the conducted computational experiment show that the specified conditions and restrictions are met; messages and parameters are correctly transmitted between the agents and the agents perform the assigned functions in the system. The results obtained will allow to model real power supply systems of any complexity in order to study the properties and improve the efficiency of these systems. The developed model enables the possibility to model complex processes in an integrated energy supply system which relate to production, transport, distribution and consumption of energy.
