<p>Traditional ships are mainly fueled by diesel or gasoline, which are produced from the oil and are non-renewable. People are now rapidly consuming oil and burning oil generates poisonous gases day and night. Because of the soaring oil prices and the deteriorating ecology, many ship-owners are seeking an alternative energy to replace oil. Among all possible candidates, the calling of natural gas is getting higher and higher. This paper discusses the application of natural gas in ship engineering, and explains in detail the advantages and disadvantages. Natural gas may not be a new energy but has rarely been used in ship engineering so far. We conclude that its application in ship engineering helps to alleviate the fuel shortage in the future. </p>

The 440 km Roma to Brisbane gas pipeline has provided a reliable supply of natural gas to Brisbane since March 1969. In those 18 years it has carried approximately 4.8 billion m8 of gas from fields in the Roma and Surat regions.Initially installed as a free-flow 10 inch gas pipeline, the system has been considerably upgraded over time. As market demand in Brisbane has increased, Associated Pipelines Limited (APL) has met this demand by gradually increasing compression along the pipeline. An outline of the approach to compression, its installation and impact on deliverability as well as the operating philosophy is discussed.The gas pipeline has six mainline compressors installed and the capacity of the original pipeline has almost doubled to approximately 65 TJ/D. The sixth compressor was planned to be the final stage of APL's pipeline capacity expansion via compression.The alternatives available to increase capacity in the future are also examined. These alternatives include peak shaving, higher degrees of compression, looping and a new pipeline. The advantages and disadvantages of each alternative are outlined. Looping is the most practical alternative. The factors involved in selecting a looping program which can be tailored to meet market demand, are discussed.

The oil crisis in the early 1980s has triggered the necessity of finding oil reserves among non - oil producing countries. India and Thailand are both oil consumption countries. Because of the rapid economic development and high vehicular fuel consumption, India has become one of the top five oil consumption countries in the world. Thailand though has less population but the demand for oil energy is still increasing. From the geopolitics perspective, Myanmar is country with abundant oil resource that located between Thailand and India, become a vital geo – economics subject for both countries. Bilateral cooperation, between India - Myanmar and Thailand-Myanmar attests the importance of Myanmar in both regards. By visiting Myanmar, India’s ministry of energy has strengthened the energy cooperation between India and Myanmar. Meanwhile, Thailand, as a natural gas consumer from both the Yadana and Yetakun, in the Gulf of Mottama or Arakan, Myanmar, has hiked up her import of natural gas from Myanmar. The agreements in the 1990s have resulted in the increase of oil imports to India and Thailand. The oil demand for both countries could lead India and Thailand into competitors. Thanks to the policy of energy cooperation between India and Thailand, their attempts are to build multilateral partnership in order to increase the capability to strengthen energy connectivity from Myanmar. By making the connectivity more convenient and efficient has led to the creation of BIMSTEC Gas Pipeline project. Myanmar as the energy leader in BIMSTEC has placed Thailand, Myanmar, India and others countries in the framework of cooperation. In the future energy will play an important role to strengthen the cooperation in BIMSTEC which highly oil consumption still continuously. This article aims to show that the cooperation like BIMSTEC can guarantee the energy dependence for Thailand and India in the future. It will also analyze their related policy formulation, such as the plan for an alternative energy security.

Current world energy consumption is likely to increase over time. This is due to the growth of industry and transportation. The most important and most used energy sources are crude oil and natural gas. The consumption of energy is increasing continuously due to the economic expansion of the world fleet. At present, prices of primary energy sources such as oil and natural gas tend to increase. In addition, oil and gas are limited and likely to run out in the future. Currently, research and research on alternative energy is ongoing. To find the best alternative energy to replace in the future. Dimethyl ether is a substance that can be used as a substitute for liquefied petroleum gas (LPG) because of its similar physical properties. Most of them are used as fuel in vehicles. In addition, dimethyl ether is easier to liquefy than liquefied petroleum gas, giving advantages in terms of storage and transport, and a higher cetane value that can be used in the vehicle. Dimethyl ether is a substance that will burn completely. Dimethyl ether production has a wide variety of options. If the best option is difficult to analyse because of the complexity of the solution. Superstructure analysis will help to find alternatives for the production of dimethyl ether. Superstructure will identify the most economical alternative. The mathematical model is applied to the existing production process and new alternatives. In this work, the alternatives to produce dimethyl ether are displayed and the optimum alternative are chosen.

In recent years, the price of oil has been soaring. As an alternative energy, natural gas could well be the main energy of the future development. Next twenty years will be the age of rapid natural gas growing. It has been predicted that China will be one of the largest global natural gas consumers. Twenty-five percent of country’s total natural gas consumption was imported. However, China is unable to be self-sufficient in natural gas resources in last ten years. So it is necessary to depend on imports to meet the rapid rise in natural gas demand. There are two main channels to import natural gas: pipeline transportation and ship-loading liquefied natural gas. Due to the limitation of pipeline transportation, ship-loading LNG will be China’s major import channel in the future. LNG is irreplaceable, wide-used, clean and low-carbon. With continued progress in mining technique and the discoveries of unconventional energy, the available natural gas resources in China will be increasingly rich; this enables sustainable development in energy. The introduction and innovation of liquefaction technique and the localization of LNG technique will improve the embarrassing dependence on imported process technology and supply strong technique support for the development of LNG. Domestic liquefied natural gas plants’ out-put is expected to exceed 7.5 million tons per year. As the key measure to reduce PM 2.5 emission, LNG will gradually replace oil as a new-generation car fuel and become the new surpass the old-timer. With the implementation of LNG terminal project, the reception capacity will gradually increase. It is predicted that the reception capacity of China will reach about 65 million tons per year in 2015. Based on the present data, the utilization and promotion of LNG will explosively grow. This article is concerned with the following topics: utilization of LNG, the future of LNG, and some related problems and suggestions regarding LNG.

The article considers the role of trust in the economy, the mechanisms of its accumulation and the possibility of using it as one of the growth factors in the future. The advantages and disadvantages of measuring the level of generalized trust using two alternative questions — about trusting people in general and trusting strangers — are analyzed. The results of the analysis of dynamics of the level of generalized trust among Russian youth, obtained within the study of the Institute for National Projects in 10 regions of Russia, are presented. It is shown that there are no significant changes in trust in people in general during the study at university. At the same time, the level of trust in strangers falls, which can negatively affect the level of trust in the country as a whole, and as a result have negative effects on the development of the economy in the future. Possible causes of the observed trends and the role of universities are discussed. Also the question about the connection between the level of education and generalized trust in countries with different quality of the institutional environment is raised.

Subject. The study analyzes generally accepted approaches to assessing the value of companies on the basis of financial statement data of ExxonMobil, Chevron, ConocoPhillips, Occidental Petroleum, Devon Energy, Anadarko Petroleum, EOG Resources, Apache, Marathon Oil, Imperial Oil, Suncor Energy, Husky Energy, Canadian Natural Resources, Royal Dutch Shell, Gazprom, Rosneft, LUKOIL, and others, for 1999—2018. Objectives. The aim is to determine the specifics of using the methods of cost, DFC, and comparative approaches to assessing the value of share capital of oil and gas companies. Methods. The study employs methods of statistical analysis and generalization of materials of scientific articles and official annual reports on the results of financial and economic activities of the largest public oil and gas corporations. Results. Based on the results of a comprehensive analysis, I identified advantages and disadvantages of standard approaches to assessing the value of oil and gas producers. Conclusions. The paper describes pros and cons of the said approaches. For instance, the cost approach is acceptable for assessing the minimum cost of small companies in the industry. The DFC-based approach complicates the reliability of medium-term forecasts for oil prices due to fluctuations in oil prices inherent in the industry, on which the net profit and free cash flow of companies depend to a large extent. The comparative approach enables to quickly determine the range of possible value of the corporation based on transactions data and current market situation.

Subject. The article discusses financial and economic momenta. Objectives. I determine financial and economic momenta as the interest rate changes in Russia. Methods. The study is based on a systems approach and the method of statistical analysis. Results. The Russian economy was found to strongly depend on prices for crude oil and natural gas, thus throwing Russia to the outskirts of the global capitalism, though keeping the status of an energy superpower, which ensures a sustainable growth in the global economy by increasing the external consumption and decreasing the domestic one. The devaluation of the national currency, a drop in tax revenue, etc. result from the decreased interest rate. They all require to increase M2 and the devalued retail loan in RUB, thus rising the GDP deflator. As for positive effects, the Central Bank operates sustainably, replenishes gold reserves and keeps the trade balance (positive balance), thus strengthening its resilience during a global drop in crude oil prices and the COVID-19 pandemic. The positive effects were discovered to result from a decreased in the interest rate, rather than keeping it low all the time. Conclusions and Relevance. As the interest rate may be, the financial and economic momentum in Russia depends on the volatility of the price for crude oil and natural gas. Lowering the interest rate and devaluing the national currency, the Central Bank preserves the resource structure of the Russian economy, strengthens its positions within the global capitalism and keeps its status of an energy superpower, thus reinforcing its resilience against a global drop in oil prices.
