Complexities in the Structural Behaviour of Offshore Structural Members subjected to Dynamic Loading
Abstract: Offshore structural members in Maritime Structures are subjected to various kinds of loading starting from Dead Load of structures and Dynamic loads from wind, waves, currents and operational loads during berthing and mooring of ships and vessels. The stability analysis of the structural members also demands an insight into the elastic properties of the founding sea bed level. Due to requirement of transport of large volume of cargoes and related …

Simplified Modelling of Wind and Wave Effects on the Performance of Floating Off-shore Wind Turbines (FOWT)
Abstract: This project continues the development of the wind and wave effects onto the performance of Floating Offshore Wind Turbines (FOWT) initiated in past studies. The previous study characterized the influence of wind-wave misalignment onto the power response of a FOWT with special emphasis on the evolution of power generation with variable angle of wind and wave related to the blade-rotor plane. In this work, the variation of the power generation …

Comparative Analysis of Different Types of Frame Structures in Vibration Analysis Using STAAD.Pro
Abstract: Bridges are structures built over rivers, valleys, railway line, roads, and its purpose is to provide crossing over obstacles. Bridges are constructed by masonry, concrete, pre-stressed materials, steel etc. Today, contemporary-day bridges generally tend to apply excessive power materials. Bridges are dynamic loadings may be uncover to the effect of vibration because of the dynamic results inclusive of wind, earthquake and automobile motion in addition to cyclic loading. In addition, …

Construction Resources Management in Niger Delta's Coastal Environments: Hydro-Geomorphological Challenges to Sustainability
Abstract: A fundamental principle of sustainability in the built environment is the minimization of resource consumption. Resource management constitutes a key theme in the sustainability agenda, which affects the financial performance of construction projects. Builders are thus concerned with the control of materials, labour and plant. However, resource management poses specialized problems for coastal construction sites, due to their inherent hydro-geomorphological characteristics. The Niger Delta Region of Nigeria is an atypical …

Wave Effects on the Performance of Giant Floating Offshore Wind Turbines
Abstract: The performance of a giant floating offshore wind turbine under the effects of wave misalignment has been modelled and simulated. Heave and period of the sea waves have been considered as the most relevant parameters to determine their effects on the power generation of the floating offshore wind turbine. The simulation has been run for two different situations, a non-restriction tilt angle case and a limited tilt angle case. The …
