Abstract
INTRODUCTION
Numerical models are now capable of
providing the quantitative description required
for engineering analysis. However, for structures
such as floating tidal stream devices, the complex
nature of the system can rarely be included using
existing functionality. Typically key aspects of the
system are considered separately or omitted from
the analysis completely. This leads to a number of
uncertainties in both the power delivery and the
survivability of these devices.
To better understand the behaviour of such
systems, a coupled Computational Fluid Dynamics
(CFD) model, including a floating barge, hybridcatenary mooring system and the influence of a
submerged turbine has been developed and tested
at full-scale in conditions based on those at the
Perpetuus Tidal Energy Centre (PTEC) site.
Simulations have been performed for a device
with and without a turbine installed; in waves and
currents, both separately and simultaneously; in
order to ascertain the influence each coupled
element has on the motion, mooring loads and
power delivery of a floating tidal stream concept
