2007 SDP Prototype

Primary Purpose:

Test concept, design,
assembly, transportation
installation and
decommissioning methods


Note: Prototype is not designed to be connected to the grid

Legend: L.A.T. Lowest Astronomical Tide

Construction of Prototype


Brindisi


Submerged Deepwater Platform


nears completion

Prototype


Launching


The unit is in 4 meters of water

Towed Out with 2 simple Tug Boats

Prototype in its final position:

11.5 NM (21.3 kms) from shore
-

113 m deep water

bladed Technology



Simple, less Expensive



Easy to Service & Maintain



Ideal for high speed wind sites



Full variable speed = max. performance




Power regulation through yaw control



Upgraded Gamma 60 turbine


on custom steel floating


support structure




Allocation of major turbine


subsystems below sea level




Hydraulically adjustable tendons,


for settlement correction only





Buoyant counterweight with


2000 t of solid ballast

Blue H:




does
not

need to prepare seabed




does
not

need to use expensive marine


services equipment


(monopolistic/oligopolistic control


of jack up barges, crane ships, pneumatic hammers for


pounding the foundations into the seabed)




does
not

need assemble at sea




does
not

have high decommissioning costs
