Cooling tower for the Ptolemais Unit V lignite-fired power plant
Ptolemaida, Greece
Ptolemaida - On site at one of the biggest projects in Greece in recent years, construction of the lignite-fired power plant Ptolemais Block V needs cooling-tower formwork expertise from Doka, plus compliance with a very special structural requirement. This is the first time that Doka has used an earthquake-proof design to form the first rings of a cooling tower.
Challenge:
The lignite-fired plant is sited in a seismically unstable part of Greece, so additional materials are needed on the site and extra safety precautions have to be implemented during the build.
Solution:
In close cooperation, Doka Greece and the GEC EN in Amstetten elaborated a specific construction concept to maximise the efficiency of the Doka formwork technology. For example more braces, anchorages and stiffening profiles are added to ensure stability during construction.
