nAbstract

n

A case is presented to closely look at the Productivity improvement of Indian Shipyards through foreign collaborations. It is proposed that Government of India, adopt two well intentioned strategies relating to carriage of Indian Cargo in Indian Built ships. All Indian Navy vessels shall be constructed in Indian Shipyards only. It is proposed that Government of India sets up a Shipbuilding Technology Centre in the immediate future. Steps have been suggested so that Government and Industry jointly can collaborate on long term basis with some advanced shipyard in Japan/Korea.

nAbstract

n

In some of the building structures, even in the newly constructed one, floating columns are used to achieve an aesthetic view or to satisfy the space requirement criteria of building areas like reception lobbies, parking spaces, conference rooms in malls etc. With the use of proper design considerations, buildings built with floating columns, which otherwise are not advised by the codes, can withstand vertical loads, i.e., gravity loads and live loads, and to certain extent may withstand the small-scale earthquake loads. However, due to vertical irregularity, that is discontinuity in load transfer from floating columns, it is more vulnerable to the earthquake loads, sometimes even to small-scale earthquakes and can lead to increased structural responses and corresponding forces in the structure. For this purpose, the response of the building can be decreased by using a seismic retrofitting technique to increase the overall performance of the building. G+9 residential floating column building is analyzed in the present study by using dynamic analysis. Arrangements are done in such a manner that use of only dampers, only bracings, a combination of both dampers and bracings as in Type 1, Type 2, Type 3, and Type 4 arrangements respectively, are considered. Location of dampers and bracings are fixed at successive and alternative floors corresponding to the height of the structure to overcome the best result in seismic retrofitting of the structure. Such arrangements are analyzed and studied by using fast non-linear time history analysis with an El Centro earthquake in ETABS v 2018. With the use of the performance controllability index, optimization of location and number of dampers can be found out using root mean square values of inter storied drifts. It can be seen that the Type 4 arrangement is quite effective arrangement to increase the overall performance of the structure with economic considerations.

nAbstract

n

The influence of the combined effects of wind and waves onto the performance of a floating offshore wind turbine (FOWT) is analyzed. A study of the wind conditions relative to the position of the aerodynamic rotor has been made, analyzing how the angle of incidence of the wind (angle of attack) varies with the wind direction and the inclination of the wind turbine mast as a consequence of the undulatory movement of the waves. This analysis should result in a theoretical model based on the variation of the angle of attack which allows the characterization of the turbine under the combined effect of the oscillation of the sea surface and changes in relative wind direction to the aerodynamic rotor. The results obtained from this research will allow designers and operators to properly manage the situation under which the FOWT is working for a cross action of wave movement and wind direction. A proposed method to compensate for the aforementioned changes in the aerodynamics of the turbine rotor is a so-called “pitch and yaw compensation” system that allows eliminating the effect produced by the variation in the angle of attack and, therefore, minimizing the effect of oscillation on the generated power generated.

Abstract

nThe influence of the combined effects of wind and waves onto the performance of a floating offshore wind turbine (FOWT) is analyzed. A study of the wind conditions relative to the position of the aerodynamic rotor has been made, analyzing how the angle of incidence of the wind (angle of attack) varies with the wind direction and the inclination of the wind turbine mast as a consequence of the undulatory movement of the waves. This analysis should result in a theoretical model based on the variation of the angle of attack which allows the characterization of the turbine under the combined effect of the oscillation of the sea surface and changes in relative wind direction to the aerodynamic rotor. The results obtained from this research will allow designers and operators to properly manage the situation under which the FOWT is working for a cross action of wave movement and wind direction. A proposed method to compensate for the aforementioned changes in the aerodynamics of the turbine rotor is a so-called “pitch and yaw compensation” system that allows eliminating the effect produced by the variation in the angle of attack and, therefore, minimizing the effect of oscillation on the generated power generated.n
