the GDF Suez – HSE Award for safety and
continuous education of site staff after the delivery
of the 800 MW coal fired power plant and 180 m
R/C chimney with FRP lining.
The work began in January 2009 and the complete
chimney as a turnkey project, including all accessories
like hoist, aircraft warning lights, lighting
protection and water supply was built within 16
months. The new coal fired power plant is scheduled
to go into operation in 2012.
The chimney is located at Wilhelmshaven, northern
Germany, and the work scheme consisted of a turnkey
contract for one reinforced concrete chimney (height:
180 m; windshield height: 177 m; and diameter
of 19 m at the bottom and 11.60 m at the top).
The chimney stands on a ring foundation which
is supported by three pile rings with 130 piles
in total; because of the bad soil conditions.
Due to the flue gas temperature of 53ºC,
Karrena recommended FRP as an appropriate lining
material for this type of “Wet-Stack-Operation”.
The 800 MW coal fired power plant and 180 m
R/C chimney with FRP lining was constructed by
using the slip form method with a maximum sliding
performance of 7.10 m in 24 hours. This allowed
finalizing the slip form works within 33 days.
According to GDF Suez Deutschland they chose
Karrena to do this job because it was “the
most competitive bid in comparison to the offered
service, its high degree of references in the
chimney business and its international business
As well, GDF Suez Deutschland valuates Karrena
because of “its harmonious and goal directed
way of communication and technical competence
and capability for problem solving”.
The chimney for GDF involved Karrena GmbH (Germany:
design, engineering, construction, project management,
site supervision) and Karrena Técnicas
del Refractario (Spain: workers).
