.... Despite this potential, only a minority of the offshore wind resource is located in shallower waters suited to fixed offshore turbines; the rest is only suitable for floating wind turbines. The Spar Floating Offshore Wind Turbine (spar FOWT) is the most common prototype the offshore industry deploys...

In this study, the phenomenon of changing stiffness hysteresis loops was observed using a small scale foundation prototype. The study is unconventional, as it assumes deformation is the cause, and the reaction...

... to have a significant effect. However in real sea state, the resonant frequency of the mechanism needs to be adjusted corre- sponding to the change of the wave frequency to achieve high energy absorbing performance. Thus, a small-scale prototype of the proposed device is designed and wave flume tests...

... ABSTRACT In this paper, two different underwater scanning technologies are described, in order to evaluate the 3D shape and colour reconstruction of submerged objects. In particular, a new laser scanner prototype (RGB-ITR) developed in ENEA Centre of Frascati (Roma) is compared...

... of floating offshore wind turbines. The Hywind model test was carried out in Marintek, in which the power of wind turbine prototype is 5MW and the scale ratio is 1/47 (Nielsen, Hanson and Skaare, 2006). The Windfloat model test was carried out in the UC Berkeley wave tank, in which the power of wind turbine...

... 2012, our group has been studying the dual flapping tidal turbine and has developed its scaled-prototype for experimental studies through two phases. In the first phase, the prototype was designed to have vertical flapping-plane with the right-swing in the front hydrofoil and the left-swing in the rear...
