Since the spread of coronavirus disease 2019 (COVID-19) pandemic, transportation cargo by ship has been seriously impacted. In order to prevent and control maritime COVID-19 transmission, it is great significance track predict sailing behavior. As nodes networks, ports call can reflect behavior ship. Accurate hierarchical division help clarify navigation law ships with different types scales. F...

In this paper, an evaluation method for effects of zero emission fuels on ship designs is proposed, and its usefulness demonstrated by trial examples as follows, 1) A to combine the price alternative fuel additional cost bunkering facility with design development individual under variable conditions proposed. 2) From a analysis Aframax tanker, in which becomes superior from aspect are shown con...

Today, wind energy contributes to the generation of electrical as well propulsion system on ships. In this study, issue optimum efficiency from turbines that can be installed ships for has been examined. context, a tanker ship was modeled and simulation study carried out. By dividing deck into five zones, it estimated which areas could receive more intense homogeneous winds. way, heights were d...

The use of fossil fuels on commercial ships significantly contributes to the increase carbon dioxide emission, and adaptation renewable energy can help control that emission efficiently. Historically, extraction wind is found be best solution for ships; recently, with renewed interest in this area, various devices are proposed literature. This study investigates effectiveness one such technolog...

Trim optimization improves the energy efficiency of ships, thus reducing operational costs and emissions; however, trim tables are only available for a limited number ships. There is desire to develop additional, more accurate without need expensive model testing. The objective this research was method decrease fuel consumption by optimization, dynamic shaft power estimation based on data. A th...

the conventional method towards deriving schedule for a fleet of ships to minimize cost alone has the short-coming of not addressing the problem of operation revenue losses associated with delays during maintenance at ships dockyards. in this paper, a preventive maintenance schedule for a fleet of ships that incorporates op-portunity cost is presented. the idea is to assign a penalty cost to al...

Sail-assisted technology can reduce greenhouse-gas emissions by saving the energy consumption of ships with wind utilization. The distribution characteristics marine resources are critical to energy-saving effect sail-assisted ships. However, due lack effective evaluation methods for improving utilization rate energy, a high potential still exists. A novel method based on resource analysis typi...

The 2007–2008 financial crisis, together with rises in fuel prices and stringent pollution regulation, led to the need update methods concerning ship propulsion system design. In this article, a set of artificial neural networks was used design equations estimate engine power consumption modern tankers, bulk carriers, container ships. Deadweight or TEU capacity speed were as inputs for ANNs. Th...

BACKGROUND Hydrocarbons which are among the major components of petroleum products are considered toxic and have been implicated in a number of human diseases. Tanker drivers are continuously exposed to hydrocarbons by inhalation and most of these drivers do not use protective devices to prevent inhalation of petroleum products; nor do they visit hospital regularly for routine check-up. OBJEC...

In the Strait of Istanbul, which is one most perilous natural waterways World, many marine accidents have occurred throughout history. Some these resulted in deaths, financial losses, and environmental disasters. The fact that a significant proportion ships passing are tanker carrying hazardous cargo further increases this danger. Especially increasing size ships, increase cost for transported ...
