International regulatory bodies such as the International Maritime Organization and National Environmental Agencies of many countries have issued rules and regulations to drastically reduce GHG and emissions emanating from marine sources. This study investigates the possibility of using natural gas and hydrogen as alternative fuels to diesel oil for marine gas turbines and uses a mathematical model to assess the effect of these alternative fuels on gas turbine thermodynamic performance. Results show that since natural gas is categorized as a hydrocarbon fuel, the thermodynamic performance of the gas turbine cycle using natural gas was close to that of the diesel case. However, the gas turbine thermal efficiency was found to be slightly lower for natural gas and hydrogen fuels compared to diesel fuel.展开更多

The conventional issue of overcapacity due to the ＂equipment battle＂, and the destructive competition have further stimulated the operating intricacy within the container sector. That would be interesting to explore the chartering strategies of CMA CGM （Compagnie Maritime d＇Affretement Compagnie Generale Maritime） in such a volatile market as any capacity adjustment dictates a line＇s profit line. Nevertheless, the usefulness of ship chartering is not only confined to the operational level but also the strategic level. Throughout the analysis of CMA CGM＇s fleet trend, fleet deployment as well as chartering activities, it can illustrate the above concepts and observe a little bit further about the strategic movement of CMA CGM.展开更多

After the first opium war, China was forced to open the gate of the old oriental country to the world. As more treaty ports opened, the import and export of goods increased the growing trade that brought about the increased demands of shipping transportation. In the same period, British, France, America, Germany and Japan governing bodies instated various kinds of laws, regulations and other policies encouraging their national shipping companies to grab shipping market share. As a result, foreign steamship companies monopolized Chinese shipping market quickly. Faced with this situation, in 1872, the China Merchants＇ Steam Navigation Company was the fisst steamship company of China to be formed. It was a government-supervised and merchant-managed company, and the Qing Dynasty government took a series of measures to support it under the fierce competition, these measures were different from foreign countries＇.展开更多
