Samenvatting:
Bottom mounted offshore wind turbines seem to have a promising futurebut they are restricted to shallow water such as in Northern Europe.
Many projects are planned or are in the phase of construction in the
North Sea and the Baltic Sea. All projects planned to date are in water
depths of up to approximately
25 m. The research project reported in this paper investigated the technical
and economical feasibility of floating wind energy systems in deeper
waters, of approximately 50 m and deeper. It is assumed that a certain
water depth floating wind turbines will have better economics than bottom
mounted wind turbines.
Floating wind energy systems seem to have some advantages over bottom
mounted wind energy systems, such as:
- lower cost installation (in a harbour)
- lower maintenance cost;
- lower removal cost.
But floating wind energy systems have their own technical challenges,
such as:
- dynamic interactions between floater and wind turbine,
- floater conceptual design including mooring system, taking into
account
restriction w.r.t. stability of floater and wind turbine, minimizing
wave induced motion, water depth, etc.
This paper summarises the activities undertaken within the Float Wind
feasibility study carried out during 2001-2002. Full details are to
be found in the Final Report [1], available from ECN or any of the authors.
