Blue H Offshore Wind Technology Developer 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 2

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

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

FCU with floaters for transport & installation Support structure in steel with concrete ballast 3D view 17

FCU, getting the dimension: bottom of central body 18

Layout of 3.5 MW nacelle 19

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

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

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 BBC headline above picture to the right: “Work on Offshore Winds Farms delayed by late arrival of the jack-up barge” Source: RMT, Inc. 24
