A nonlinear model of bolt joints structure in vibration environment is built and Structure Intensity(SI) of it is calculated by FEM as an approach for the state identification of bolts joints structure in vibration environment. The plots of the structure intensity vector under different preforce were obtained and showed the SI changes of bolt joints structure with different preforces.and showed the energy distribution and transmission are different preforces

The structural intensity of shells structure was analyzed based on finite element method (FEM) in this paper. The expressions of structural intensity of plate in FEM were given under harmonic excitation. By using coordinate transformation, mathematical expressions of the structural intensity of shells structure in FEM were deduced. The structural intensities of a rectangular plate and combined structure of tube and plate were calculated. The vector plots of structural intensity under different excitation frequencies were analyzed. The results show that the structural intensity under different frequencies are different, the vector plots present directly the distribution and propagation of energy in shells structure.

The transportation of goods worldwide has a vital meaning for the entire of humanity. The seaborne transport is considered to be the most efficient – economically and environmentally friendly way to convey large amount of goods when compared to the other transport options available. Marine vessels contribute for the carriage of about 90 percent of the worldwide trade and a significant part of the goods delivered by sea are performed by container vessels. Even considered as the most efficient way of transportation the negative aspects of the shipping should not be neglected. The fuels intended for the ship propulsion generating enormous amounts of Greenhouse gases (GHG) and harmful emissions which are directly released into the atmosphere. When it comes to Energy Efficiency of the ships, the proper selection of the propulsion system and the fuel type used are essential with regard to achieve the best values. In the current paper a diverse alternative propulsion system options in order to achieve maximum Energy Efficiency on various sizes of container vessels will be analyzed.

There is a growing interest in the appearance of LNG fueled large commercial ship with rising oil price and stronger emission regulation of these days. Though small or middle size LNG fueled vessels have been already operated, the application of LNG fuel to large commercial vessels is now under developing in stage. LNG fueled propulsion system can be characterized by three differences than typical propulsion system. First one is 2-stroke dual fuel engine, second one is high pressure fuel supply system and the third is LNG fuel tank. Among these three components, this paper is focused on the LNG fuel tank which was developed by DSME so called ‘ACT-iB’ (ACT-iB: Aluminum Cargo Tank Independent type B). This paper describes engineering works such as structural analysis, crack propagation & leakage analysis and temperature distribution analysis for the application of ACT-iB to LNG fueled vessel. From this development, it was concluded that LNG fueled technologies are ready to large container ship application in structural point of view.
