One of the ways to achieve this goal is slow steaming, which reduces fuel consumption and CO2 emissions. The designed speed of the vessel has a significant impact on the efficiency of slow steaming. Slow steaming is particularly suitable for large container ships with a design ...
A year-long noon report data is received from a container ship and LNG conversion is performed. Savings from both the fuel expenses and the amount of the emissions are calculated and presented. To eliminate the fuel consumption uncertainties in future operation periods of the stated ship, ...
To address this research gap, we develop simplified and composite ship fuel consumption models for ocean-going container ships by size using a regression model. To estimate the fuel consumption models for container ships, we rely on ship activity data, including average speed and sailing time, ...
As the basis of these kinds of programs, we develop a viable research methodology for modeling the relationship between the fuel consumption rate of a particular container ship and its determinants, including sailing speed, displacement, sea conditions and weather conditions, by using the shipping ...
Modifying the ship’sbulbous bowis an efficient way to reduce fuel consumption of ships. Companies like NYK group and Maersk line has used this technique successfully to improve fuel consumption. NYK group has made bulbous bow energy-saving adjustments to a containership resulting in a verified 23...
Ship fuel consumption is a major component of maritime transport costs and most of its emissions are harmful to the environment. Hence, it is essential to build an accurate ship fuel consumption prediction model, thereby providing reference to the navigation operations. However, maritime industry expe...
First, traditional sails require huge crews. Something the size of the 921-tonne tea clipper Cutty Sark needed a crew of about 30 to handle the sails and the complex sheets and lines that controlled them. Compare that to a modern 196,000-tonne container ship that needs only 13 officers and...
Owing to high fuel costs and environmental regulations, the optimization of ship speed to minimize fuel consumption and reduce carbon emissions has become a hot issue in the maritime industry. In this paper, we study the sailing speed optimization problem for a ship operating on a route having ...
The results include the use of methanol fuel as the main fuel for a cellular container ship. The environmental benefits of methanol-diesel dual-fuel engine are discussed based on the fuel consumption and the emission calculations. In addition, the economic benefits of the dual-fuel engine are an...
3. This paper gives a brief introduction to the exploration of global uranium resources, and analyzes the explored reserve and potential of uranium, production, consumption and supply of nuclear fuel, and the guarantee of uranium resources to the world's nuclear power. ...
