I put in a \clearpage command but that should not be the solution.\begin{wrapfigure}{r}{3.6cm}

\subsubsection{Space frames}
This type of substructure comes closest to the structures used in the light weight and cost efficient steel spaceframes (often reffered to as jackets) used for smaller oil- and gas related production facilities. A three or four legged frame is placed on the sea bed and anchored with piles, either through the legs or through a sleeve at the bottom of each leg. These foundation piles are relatively small (1 to 2m diameter) compared to monopiles. This allows for use of smaller, more commonly available equipment for installation. The space frame is suitable and economic in larger water depths.
Recently the Beatrice wind farm has been installed, two REpower 5MW turbines were installed in 45m water depth. The substructure in this pilot project is a four-legged, 62m high frame with a footprint of 20 x 20m.

\subsection{Floating substructures}
Floating structures derive their stability based on their shape and buoyancy characters, but principles here can be quite different:\\
\begin{array}[h]{l l}
\text{i}& \text{Tension Leg}\\
\text{ii}& \text{SPAR-bouy}\\
\end{array}
However technically feasible, based on economics floating wind turbines are not an option yet. BlueH, a Dutch company recently installed the first floating 80 KW turbine ever. The structure is based on the tension leg principle located approximately 15 km off the South Italian coast in water depths of 108 m. The same company has been nominated for a 420MW commercial wind energy project in the USA.\footnote{source: http://www.bluehgroup.com}\\
Norsk Hydro is currently developing what they call a floating wind mill. The SPAR type structure that has been model tested and is planned to have its first prototype ready in 2009.
And can anyone see why that array on the bottom should give an error (sais Missing $ inserted )
Thanks again.
