World globalization creates a dependence on timeliness and security of supply which is carried out through the complex preparation and implementation of the spatial and temporal transformation of goods, services, and knowledge. Maritime transport is the most represented form of freight transport, which accounts for about 80% of the total world transport, while 60% of the freight in maritime transport is transported by container vessels. The purpose of container vessels in the supply chain is to connect the global economy where the lowest representation of cargo transportation costs is manifested through demand. The reason for this is the trend in production which requires economic efficiency through finding locations of lower costs. The concentration of production at the world level covers the Asia and Pacific region, which has created a great distance in terms of Europe. Distance brings with it risk that is reflected in the supply chain. Delays, numerous loading, unloading and transshipment points create an additional problem when it comes to quality organization of logistics. On the other side, the reliability of the means of transport used to transfer goods over an extremely long distance is also important. The end customer is constantly demanding a reduction in transportation costs and delivery times, while logistics is trying to manage and respond to their demands. The global exchange of goods is primarily distributed by maritime transport in which container vessels play a key role. Their importance stems from the majority of the share of global freight transport, where supply chains have gradually become dependent on this type of transport. Container vessels main engine parts failures cause delays and obstruction of the supply chain, i.e., an increase in logistics costs, which ultimately generates higher total costs. For these reasons, the reliability of the container vessels main engine parts is necessary. Reliability ensures reduced costs, and time and increases the security of delivery in the supply chain. The specification of parts is reduced to the criteria of the same name due to the homogeneity of the technical components system. During the vessel navigation, professional and trained staff, which owns experience-based capabilities, conduct most of the main reviews of the engine, which is also the most reliable basis for recording the condition of the equipment. Prevention is achieved by recording failures, their causes, and the conditions in which they occurred. However, it is important to monitor the operation of the components of the main engine according to the technical manual prescribed by the manufacturer. Every change of state is conducted with records in various available programs that provide insight into the history of the entries data and monitored work. The possibility of unplanned stoppages and breakdowns can create additional costs, where every hour increases operational costs for the shipowner, and as a result, consternation in the supply chain occurs. The task of professional staff, responsible for economical and reliable exploitation, is to reduce or prevent the possibility of breakdowns. The research is based on the data of container vessels, which are in operation, within a period of 11 years. Weibull distribution is the most widely used in failure analysis, which shows that through a certain interval, very complex laws of randomly varying quantities can be interpreted by choosing appropriate value parameters. As the main result of the research, it is expected to determine the reliability of the production of individual components of the container vessels main engine and their influence on the functioning of the shipping company's logistics system. Proposals for solutions will be based on the conducted analysis and the Weibull distribution. Based on the aforementioned distribution, the data with an emphasis on the primary components will show the number of working hours during which the most failures occurred, and with this knowledge, will be concluded certain reliability and a plan for changing the individual components of the container vessels main engine. The obtained results can be used as a basis for optimizing the work of container vessels, and shipping companies.
