Unveiled
in
2009,
the
W2Power
concept
is
based
around
a
“large
but
lightweight”
three-column
semi-submersible
hull
with
conventional
three-bladed
wind
turbines
mounted
on
two
corners
of the
triangular
structure.
The
three
sides
of
the
tubular
steel
platform
are
arrayed
with
banks
of
six
small
wave-energy
converters
(WECs).
The
Norwegian
ocean-energy
technology
developer
envisages
using
a
pair
of
medium-sized
wind
turbines
on
the
floater,
probably
akin
to
Siemens’
or
Shanghai
Electric’s
3.6MW
model,
which
would
feature
107-metre-diameter
rotors
powering
a
three-stage
geared
drivetrain
and
asynchronous
generator.
The
18
WECs
are
tried-and-tested…
