The split installation and application of offshore wind turbine generator systems

Sun Guangxi,Huang Yaxin

Strategic Study of CAE 2010, Volume 12, Issue 11, Pages 53-59

Abstract:

The installation methods used in offshore wind farm around the world were summarized, and the process of split installation, the set necessity and principles of assembly base were analyzed. 8 kinds of typical land-based assembly programs and the assembly technology of main parts were summarized. An installation method was proposed by sitting of the diving boat. The diving installation ship was made by installing a crane, and was located in the seabed during the operation to hoist the turbine components. The installation method is suitable for offshore wind farm construction. The application of the installation method in the test turbine project of Jiangsu Xiangshui offshore wind farm was introduced in the paper finally.

Keywords： offshore wind farm method of assembled on shore method of split installation application

Marble epistyles under shear: an experimental study of the role of “Relieving Space”

E. D. PASIOU, I. STAVRAKAS, D. TRIANTIS, S. K. KOURKOULIS

Frontiers of Structural and Civil Engineering 2019, Volume 13, Issue 4, Pages 767-786 doi: 10.1007/s11709-019-0515-9

Abstract: The mechanical response of mutually interconnected epistyles is studied experimentally. The specimens are made of two marble blocks connected to each other with an “I”-shaped titanium connector placed in grooves sculptured on the blocks and covered with cementitious material. The specific way of connecting epistyles simulates the one used by scientists restoring the ancient “connections” of the epistyles of the Parthenon Temple. This “connection,” although designed to sustain mainly tensile loading, undertakes, also, shear load, in case of excitations imposing to the epistyles displacements normal to the connector’s axis. Attention is focused to enlighten the role of a novel design technique aiming to relieve the stress field around the connector. According to this technique, part of the connector’s web is left uncovered, forming the so-called “ ,” assisting the unconstrained deformation of the connector. Both traditional and innovative sensing techniques were employed in an effort to obtain data from the interior of the three-material-complex (marble-cementitious material-titanium). Analysis of the data indicated that the “Relieving Space” reduces the overall stiffness of the system, protecting marble in case of over-loading. Moreover, it was concluded that the innovative techniques employed provide pre-failure indicators well in advance of the catastrophic failure of the specimens.
