--Most of the structures in flowing water are a challenge to their stability and sustainable with different flow conditions. Recent, renewable energy research and development covers ocean and river energy platform in which flow of water drag considered in various conversion devices towards the offshore and onshore establishment. Various energy platforms have been suggested for offshore developm...

In this study, an unsteady aerodynamic simulation is performed to realize the influences of platform surge motion on the aerodynamic performance of a high capacity offshore floating wind turbine. A dynamic model with pitch angle control system is utilized to propose a more realistic model of wind turbine and also achieve the rated condition of the rotor. The transient effect of platform surge m...

Many innovative floating offshore structures have been proposed for cost effectiveness of oil and gas exploration and production in water depths exceeding one thousand meters in recent years. One such type of platform is the offshore floating Spar platform. The Spar platform is modelled as a rigid body with six degrees-of-freedom, connected to the sea floor by multicomponent catenary mooring li...

This paper discusses the design of hydrodynamically scaled models of offshore structures subjected to wave loading. A considerable amount of engineering design and analysis is required to ensure the high performance of a model/dynamometer system, especially when dealing with large scale models (for example, 1:40). The system is designed to be as rigid as possible so that the dynamometer measure...

VSC HVDC will be the most important approach for transmitting the power of large-scale offshore wind power plant in the near future. In recent literature, the feasibility of using hybrid type HVDC for offshore wind transmission has been discussed. A hybrid HVDC system has at one line commutated converter (LCC) at mainland and one voltage source converter (VSC) at offshore platform, which may in...

The paper studies the performance of Offshore Wind Turbines (OWTs) founded on Suction Bucket Jackets (SBJs) in clay under combined wind and seismic loading. A detailed 3D FE model soil–foundation–structure (SFS) system is developed used as a benchmark to assess efficiency an enhanced Winkler-based "Caisson-on-Winkler-Soil" (CWS) model, where soil replaced by nonlinear hysteretic elements. propo...

Offshore Wind Turbine (OWT) support structures are subjected to hostile environments, defined by highly stochastic loads and complex soil-structure interaction, thus the need for a probabilistic approach towards design. The study carried out herein presents sensitivity analysis of these inherent variables imposed on OWT structure via purpose-developed modular non-intrusive structural reliabilit...
