... Abstract This paper proposes optimization methods for the large cranes in the construction process of functional modules, jackets and steel piles. Functional modules are partially constructed in the way of jacking up instead of the traditional lifting way by cranes, and jackets are installed...

... of penetration of petroleum derivatives on a soil profile, current aeration of this thickness and methods of its optimization by the way of soil loosening in dependence of depth and character of the predicted oil pollution should be typified to fulfill the operations on purification and remedy.

... and the body is needed for optimal cruising range. In this study, calculations of the flow field around the body were carried out based on computational fluid dynamics and the body shape was optimized to reduce the resistance and to improve efficiency of the propeller. The drag coefficient of the body based...
