Ballast Nedam Signs Contract for Walney II Offshore Windpark

NIEUWEGEIN, The Netherlands, June 8, 2010 - Ballast Nedam Offshore has signed a contract with Walney (UK) Offshore
Windfarms Ltd (a joint venture between DONG Energy of Denmark and Scottish
and Southern Energy in the UK) to install 51 foundations for offshore wind
turbines as part of the Walney II project. A Letter of Intent to this effect
was signed in December 2009. The project is located in the Irish Sea, 20
kilometres off the west coast of England near Barrow-in-Furness. The 51
turbines each have a capacity of 3.6 MW, resulting in a total capacity of
183.6 MW.

Ballast Nedam Offshore will install the tubular steel piles which form
part of the foundations. These monopiles weigh between 800 and 1000 tons
each, which makes them the heaviest monopiles ever used as the foundation for
an offshore wind turbine. Nevertheless, the weight involved is well within
the maximum lifting capacity of Ballast Nedam's heavy lift vessel Svanen,
which is built to handle 8,700 tons. The Svanen will start putting the
foundations in place during the second quarter of 2011.

The construction of Walney II represents a milestone for the Svanen. Not
long after the project gets under way, the vessel will place its 250th
foundation for offshore wind turbines. The Svanen has built up an impressive
record, installing the foundations for offshore wind parks at Egmond aan Zee
(the Netherlands, 2006, 36 piles), Rhyl Flats (United Kingdom, 2008, 25
piles), Gunfleet Sands (United Kingdom, 2008/2009, 32 piles) and Belwind
(Belgium, 2009/2010, 56 piles).

The Svanen is currently installing 90 foundations for the Sheringham
Shoal Offshore Wind Park in the United Kingdom, which lies between 17 and 23
kilometres off the coast of Sheringham. In addition, Ballast Nedam Offshore
is using another vessel to install 22 foundations for the Baltic I wind park.
German energy company EnBW is the commissioning party for Baltic I, Germany's
first commercial wind park.
