ccess to an offshore wind turbine is greatly limited by the environment; consequently operation and maintenance (O&M) can become more sporadic and infrequent. This reduces the turbine availability, thus decreasing the generated output [1]. O&M is already a large part of the life costs of a turbine, but with offshore turbines, this will increase greatly with the inclusion of vessel hire costs [2...

The paper proposes a methodology for reliable design and maintenance of wind turbine rotor blades using a condition monitoring approach and a damage tolerance index coupling the material and structure. By improving the understanding of material properties that control damage propagation it will be possible to combine damage tolerant structural design, monitoring systems, inspection techniques a...

The multi-wind turbine platform technology has the potential to harness significant source of offshore wind energy in deep waters. However, wake interference between turbines on can cause a reduction power production; hence, it is important study effects initial phase design. This paper studies three different configurations find suitable configuration for multi-turbine platform. analytical Lar...

This paper proposes the use of a tuned mass damper fluid-inerter (TMDFI) for vibration control spar-type floating offshore wind turbine towers. The an inerter in parallel with spring and (TMD) is relatively new concept. ideal has amplification effect on classical TMD leading to greater capabilities. Previous work by authors shown that based TMDs have great potential turbines where enhanced miti...

Recently, there has been a fast development and deployment of wind energy to meet the increasing electrical power demand and to limit the use of fossil fuels. More and more wind farms are planned far from shore because of good wind condition and less visual impact. This is so called offshore wind farm (OWF). In such a situation, high voltage direct current (HVDC) transmission is a favorable opt...

Abstract This paper summarizes the scaling approach and results from first experimental campaign of Floating Offshore-wind Controls Advanced Laboratory (FOCAL) Experimental Program, which is focused on developing public data sets to support validation numerical models for floating wind control co-design. A 1:70 Froude-scale performance-matched model IEA Wind 15-MW reference turbine was designed...
