15. 2007: Blue H acquired Gamma 2-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 15

16. The First Commercial Unit - FCU
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

17. FCU with floaters for transport & installation Support structure

20. The O&M and industrialization strategies of the
3.5 MW unit guide the design concepts
Easy access by a safe
gang-way to all parts of
the nacelle
Patented assembly
method:
Drive-train and generator
mounted on a container
shaped false bed-plate,
assembled at yard on
the real bed-plate 20

21. Blue H Intellectual Property
IP on the Tension Legged Platform (TLP)
IP on the 2-bladed Turbine for Offshore Use and/or Onshore Use
IP on integrating the TLP with the Turbine
Various patents on two-bladed teetering hinge turbine and
design solutions for transport, installation and industrialization 21

24. Blue H Solution is designed to be more Economic
than Current Shallow Water Installations
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
