Research on the Effect of Fluid and Ribs of Double-shell on Its Sound Radiation
The problem of sound radiation from shells of fluid-structure coupling is involved in many academic subjects. This is the advanced problem in the domain of structural acoustics. Cylindrical double-shell structure is the basic component. It is widely used in the engineering field. The research on these structures’ underwater acoustic-vibration characteristic takes a significant role of [...]
The Finite Element Analysis on the Seepage of Dock and the Stress of Dock Floor
The level differences of groundwater and great hydraulic gradient must be formed when drainage system is used to drain the seepage flow of a dry dock around which there are high groundwater and river levels. At the same time, the seepage under floor will produce uplifting pressure under the dock floor. The dock floor will [...]
Experimental Investigation of Suppression of Vortex Induced Vibration of Deepwater Risers
Vortex induced vibration(VIV) is one of the important factors lead to the structural instability and fatigue damage.In practical engineering,to ensure long deepwater risers safety and structural instability,in order to find a good method to suppress vortex induced vibration of deepwater risers.Experimental investigation was performed by testing a riser without VIV suppression and with three controlled [...]
Study on Adsorption Power of Submersible Structure from Sediment
Adsorption power is a common force in ocean engineering and port engineering.The submersible structure of the ocean engineering and port engineering needed to be lifted because of being reused or other reasons.So the adsorption power coming from structure and surrounding sediment is the primary force in the process of lifting.If the value of adsorption power [...]
Safety Assessment of Oil Tanker’s Fire and Explosion Accidents Based on Fuzzy Theory
As the demand and consumption for oil increased day by day in each corner of the world,its transportation depends much more on oil tanker,and plays an more and more important roles in social development.Because it offers us the method of long distance and large amount transportation.But compared with other kinds of ships,oil tanker has its [...]
The Safety Assessment Research of Bo Hai RO/RO Passenger Ship’s Fire
Fire accident is one of the main threats to ship.With the development of shipping trade,RO/RO passenger ship plays a more and more important role in shipborne service of enclosed sea,channel and Yangtze-kiang.With the development of science and technology,the construction of the RO/RO passenger ship tends to be bigger,faster and more automatic which leads to more [...]
Design and Relization of Marine Traffic Accounting System
Marine traffic survey or marine traffic investigation basically aims at utilizing all available methods to collect water traffic data and then to analyze,study,finally to learn and master the water traffic circumstance,general characteristics and laws from the microeconomic and macroeconomic view.Marine traffic survey or marine traffic investigation involves three parts.of work: to collect the original water [...]
Research on Forecast of Ship Traffic Accidents Based on MGM(1, n) Model
In this paper, firstly we analysis the affecting factors about ship traffic accidents including people factors, vessel factors, environment factors, and management factors etc; after referring a lot of information, analyzing and summarizing the previous research, this paper confirms the relatively important factors on the basis of previous qualitative analysis such as expert investigation method [...]
Study for the Effectiveness of VTS at Cheng Shan Tou
Chengshantou is located at the easternmost of Shandong peninsula. The waters of Chengshantou are the hub of China’s north-south sea transportation, and the only way for ships going to/from ports around Bohai Ocean and North Huanghai Ocean. The average number of merchant vessels going through the waters each day is around two hundred. In addition, [...]
Experimental Investigation of Vortex-induced Vibration of Long-flexible Marine Risers
The primary objective of this thesis is to improve the understanding of vortex-induced vibrations(VIV) for cases with very high order of responding modes,analysis the effect of suppression device,and try to improve the ability of modeling long-flexible risers at high-mode numbers.As part of this thesis work,two separate experiments have been planned and executed in SLCOE(the State [...]
