Proposition

“Offshore wind offers enormous potential, with stronger more

predictable winds ......... Planning permission can be easier to obtain

than onshore, farms can be built at scales impossible on land, and the

availability of space is almost unlimited if deep waters are mastered.” - World Economic Forum 2009 – Green Investing

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

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

• 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

Layout of 3.5 MW nacelle

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

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

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
