Moonpool is an opening in the floor or base of a hull ship which can be used to lower tools and vehicles into the sea in a protected area. In this paper, the effect of a rectangular cross section moonpool on the resistance force of a supply vessel was investigated both by experimental and numerical methods. For both methods a 1:37.2 scale of Caspian3 surface vessel was used. Experiments were ca...

Many existing phenomena in nature are considered new design ideas in various fields of industry. Bionics is the application of biological methods and systems found in nature to the study and design of engineering systems and modern technology. By performing bionic review, the researchers found the penguins by delivering air locked under their wings and creating air bubbles, the drag significant...

This paper deals with simulation modeling of the vessel traffic in Delaware River. The purpose is to study the impact of deepening on the navigational efficiency in the River. In this regard, vessel calls to terminals, lightering and barge operations, tidal and navigational rules in the River, terminal and anchorage properties as well as vessel profiles are considered in the model. The simulati...

We have developed software for the realistic simulation of a single vessel from an angiogram. Initially a parameterized space curve is generated which specifies the path of the vessel in a three-dimensional space. The position of an aneurysm or stenosis along the path of the vessel may then be specified. Finally, the volume of the vessel is constructed along the space curve, and the resultant i...
