DFIG versus PMSG for marine current turbine applications [PDF]
, 2012 Emerging technologies for marine current turbine are mainly relevant to works that have been carried out on wind turbines and ship propellers. It is then obvious that many electric generator topologies could be used for marine current turbines. As in the

High Strength Steel Fatigue Crack Growth Database for Offshore Renewable Energy Applications
Fatigue &Fracture of Engineering Materials &Structures, EarlyView.ABSTRACT High strength steels can reduce costs and carbon emissions in offshore renewable energy, but their effect on structural integrity remains unclear. In welded structures, such as support structures for offshore wind and tidal turbines, fatigue life is dominated by crack growth from flaws at weld toes.
