The 33 MWe turbine generator TG2 is one of the two steam turbines of the power plant situated in the chemical industry zone of SYNTHOS Kralupy, part of Synthos Group, manufacturing and supplying its clients with chemical products and solutions for further processing. The factory is situated in the town of Kralupy nad Vltavou on the Vltava river ca. 30 km from Prague.
The customer was looking for a service provider that could do a full revision as a turnkey project. As an independent service provider for equipment originally supplied by a wide selection of different OEMs, Fortum was able to offer the customer a total delivery including overhauls of both the turbine and the generator. With this structure and operating model, Fortum’s offer was also the most cost-effective solution.
“We had already earlier provided the customer with expert services, but this is our first contract with a wider scope. We are very proud of this cooperation with Synthos, as it reflects the customer’s possibility to choose also among non-OEM service providers as well as Fortum’s competitiveness in this new market area. The customer will benefit from our 30 years of experience with rotating main equipment management and our business model where the turbine generator is serviced in our own fully equipped workshops,” says Vesa Kylmälä, Head of Turbine and Generator Services, Fortum eNext.
Importance of precision
As always, the delivery is being done under tight time pressure. In practice, the turbine generator is disassembled and sent to Finland and Sweden for inspection and necessary repairs. Fortum eNext has two dedicated workshops, in Naantali, Finland and in Västerås, Sweden. The workshop in Naantali is designed for full-scope turbine maintenance services and is also equipped with servomotor testing and service facilities. The workshop in Västerås is fully equipped to repair and rewind both rotors and stators. Adjacent to the workshop facilities, Fortum eNext also operates the only independent high-speed rotor balancing facility in the Nordic countries.
The turbine and the generator were dismantled in June, and inspection and maintenance work was carried out in July and August. The assembly work began in late August and will be completed in early October, followed by testing and commissioning. The project employs around 30 people from June to October, about half of them are Fortum’s own experts and project specialists.
For more than 30 years, Fortum has served over 200 customers with turbine and generator services in more than 20 countries globally.
