Exhaust or exhaust gases of internal combustion engines are one of those man-made factors. All countries \u0000impose restrictions on the concentration of hazardous substances, for example: Euro - for cars, Tier and Stage \u0000- for heavy equipment and MARPOL-73/78, which regulates emissions from maritime transport. The situation \u0000is extremely acute for marine vessels, since engines of impressive power that operate for a long period are \u0000difficult to adapt to stringent environmental requirements. The purpose of the article, based on open sources, is \u0000to evaluate the prospects for the development of internal combustion engines with an exhaust gas recirculation \u0000system to minimize the amount of toxic emissions into the atmosphere. The development of technologies that allow for the recirculation of exhaust gases in ship conditions is quite promising. The installation of such equipment \u0000will significantly reduce emissions into the environment. \u0000Keywords: environment, exhaust gases, toxic emissions, internal combustion engines","PeriodicalId":19521,"journal":{"name":"Operation of Maritime Transport","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81764137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The global freight market for tramp tonnage is a market of perfect competition for \u0000the following reasons: a large number of sellers and buyers of homogeneous products independently operate \u0000on it; each of them cannot significantly affect the level of freight rates and has fairly complete information \u0000about prices and costs. Due to the fact that tramp ships are not associated with a specific navigation area and \u0000go where there is a need, the tramp market is sensitive to changes in supply and demand, it is characterized by \u0000significant fluctuations in freight rates. In this regard, the research topic is relevant. \u0000Within the framework of the article, the authors propose a methodical approach to determining the possible \u0000range of freight rates in tramp shipping, taking into account the input parameters of the upcoming voyage and \u0000the current state of the freight market. The practical calculations carried out allowed us to conclude that today \u0000for ships of the size \"Handymax\" in the geographical section of the Black Sea-Mediterranean Sea, the gap \u0000between the minimum and maximum possible freight rates for ships of the same age can reach four dollars per \u00001 ton of cargo","PeriodicalId":19521,"journal":{"name":"Operation of Maritime Transport","volume":"108 1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82804829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The technological process of \u0000container transshipment in the operational areas of the terminal and formation of auxiliary stacks for further \u0000transfer of cargo between different transport means, their temporary storage and transformation (from containerized \u0000form to general cargo and back), as well as the implementation of secondary operations (checking, \u0000weighing, etc.) are the object of research. From an operational point of view, the formation of an auxiliary stack \u0000is a time-taking technological operation, as it requires the selective search and withdrawal from the general \u0000stack of a certain number of containers that make up the logistic flow of cargo moved to the relevant operational \u0000zone. The method of research is automatic programming of the simulated technological process. In this case, \u0000the simulation object is described by a finite automaton which is then converted into code. The main purpose \u0000of the automaton is to implement the control function. In the context of this research work, the control actions \u0000are aimed at the reloader and program the sequence of its actions to find the target containers in the stack. A \u0000mathematical model of the search and withdrawal of the target containers from the stack in the terminal storage \u0000area by means of a computerized control system, as well as a transition graph of the finite automaton with \u0000control rules (codes) are the results of this research.
