Offshore wind is the logical next step in the development of wind energy. With higher wind speeds offshore and the fact that turbines can be placed out of sight, offshore wind helps increase the amount of renewable energy signifi cantly. Offshore wind has been developed through pilot projects in the 1990s and has seen commercial development over the last decade. This chapter shows the developme...

This paper introduces the concepts of platformless DC connections of offshore wind turbines. First, the paper describes the possible and preferred wind turbine drivetrain arrangements capable of producing sufficiently high DC voltage. Then, the electrical system designs appropriate for the platformless DC architectures are discussed. After that, the potential economic benefits of direct DC conn...

In order to meet the demands of turbine integration into the wind park grids, advanced power converter technologies have successfully been developed by ABB. Along with the ongoing move from onshore to offshore wind installations, the system reliability, maintenance costs and product quality have come into focus to a far greater extent. Even the smallest service for offshore installations immedi...

This paper aims at investigating the effect of water depth increase on global performance a floating offshore wind turbine, with special focus environmental loading effects and turbine operating status. An integrated aero-hydro-servo-elastic (AHSE) analysis was simulated in time domain. The model first validated against published results terms mooring system restoring force platform natural fre...

Over the past few decades, wind energy has emerged as an alternative to conventional power generation that is economical, environmentally friendly and, importantly, renewable. Specifically, offshore wind energy is being considered by a number of countries to harness the stronger and more consistent wind resource compared to that over land. To meet the projected “20% energy from wind by 2030” sc...
