Shipping log data based container ship fuel efficiency modeling
Transportation Research Part B: Methodological, 2016Container shipping lines have been initiating various ship fuel efficiency management programs because bunker fuel costs always dominate the daily operating costs of a container ship. 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 ...

Alternative Fuels versus Traditional Fuels in Shipping
SNAME 6th International Symposium on Ship Operations, Management and Economics, 2018The main source of emissions from sea-going vessels is the exhaust gas from burning fuel in the ship's combustion engines. The first regulation of exhaust gas emissions from ships, which came into effect twenty years ago, was not strict. However, the global 2020 cap on maximum 0.5 % sulphur in the exhaust gas from the ships combustion engines, in ...

Microbial Contamination of Ship Fuels
1981A laboratory evaluation has been made of water-soluble biocides which might be effective in controlling microbial contamination in water-compensated fuel storage tanks on naval ships. Higher concentrations of biocides were generally required for control of sulfate-reducing bacteria in steel drums simulating ships' tanks than in test-tube scale assays ...

Fuel Minimisation for Ship Weather Routeing
IFAC Proceedings Volumes, 1997In this paper, we present a ship weather routeing procedure that minimises a fuel criterion. The minimisation algorithm is designed so as to enable the ship to respect her planned arrival time. Based on the dynamic programming procedure, in which the ship power is considered as an additional input variable, the method has been implemented using a ...

Hydrogen Fuel Cells for Ship Electric Propulsion: Moving Toward Greener Ships
IEEE Electrification Magazine, 2020This article addresses several challenges related to the development of zeroemission ship propulsion through hydrogen fuel cells (FCs) as the main source of energy. One main barrier to the development of FC propulsion is the production and transportation of hydrogen. However, in this article, it is assumed that hydrogen is available in the form of pure

A Statistical Approach to Ship Fuel Consumption Monitoring
Journal of Ship Research, 2015The reduction of the environmental impact imposed by Kyoto Protocol and the growth of competitiveness imposed by the shipping market have urged shipping companies to pay increasing attention to ship energy efficiency improvement and CO2 emission reduction.

Low sulfur fuel handling for ships
World Pumps, 2020Desulfurization has reduced the lubricating properties of fuel, often leading to pump failure. Here, Philip Sulzer, technical manager KRAL GmbH, explains how the surface hardness of its screw pump components was increased to handle the low sulfur fuels now used in today's shipping.
