A suspension bridge is a structural system that was used by the Red Indians' and still it is considered to be the latest technology in bridge construction. Due to their aesthetic appearance, efficient utilization of structural materials and other notable advantages suspension bridges have gained much popularity in recent decades. The recent developments in design technology in bridge engineering enable the construction of lighter, longer, and more slender bridges at the cost of losing stiffness and damping properties. This book is mainly focused on the effect of external damper on various responses of bridges such as displacement, acceleration, natural frequency etc. at selected joint. It also focuses on the effect of positioning of dampers on suspension bridge. For this analysis finite element method was used and FEM software SAP2000 was used for the analysis.The study reveals that by properly selecting the parameter of damper the response of the bridge can be controlled and effectively used for cost optimization without suffering the drawback of disrupting the aesthetics of the bridge.

This book presents the conceptual design of an FPSO which suits the parameters of a specific oil field. It has been divided into five sections. They are - Vessel selection, Tanker refurbishment and conversion, Topsides selection, Mooring and Hydrostatic and Stability checks. A Very Large Crude Carrier (VLCC) is proposed as the desired vessel. Internal mooring system is selected to deal with extreme weather. Suitable tanks have been modeled to provide desired storage capacity. Major aspects associated with tank renovation and conversion has been discussed. Simplified calculations for steel renewal and typical total required volume of steel have been presented. In designing topsides three major requirements has been fulfilled. For mooring system design, the applied standard was API-RP-2SK. For Hydrostatic and stability calculation, a model of the proposed FPSO has been developed. Damage statical stability analysis is performed for full flooding damage of six different compartments. Finally Some recommendations are provided at the end of the report regarding further improvement of the proposed Design.
