3 SynCon stations for improved grid stability in Estonia

Transport and unloading of heavy components for 3 SynCon stations in Estonia

After months of planning, Rolf Riedl GmbH and its subsidiary RTM Riedl & Tschierschke Montage GmbH have successfully transported all 9 heavy components, and positioned them to their foundations, for 3 SynCon stations in Estonia.

The SynCon stations are an important addition to the existing electricity system in Estonia in order to become independent of the Russian power grid.

The stations are not in continuous operation and are only switched on when necessary to maintain the stability of the electricity system.

Shipping and transportation was completed from Croatia via Hamburg to Estonia.

First, the transformer weighing 155,000 kg, including accessories, was loaded onto a ship with crane gear in the Croatian port of Rijeka. The ship then travelled to Hamburg to load the 271,000 kg generator together with its covers. The generator measured 11.80 x 3.93 x 3.65 meters.

After loading, the ship continued its sea voyage towards the Estonian port of entry. When it arrived at the port of destination, the generator was first loaded directly onto a truck using the ship’s crane and driven to the interim storage area in the port. The same truck then loaded the transformer and transported it directly to the construction site the following night.

Our assembly crew from RTM were already waiting with a lifting system set up and transhipped the transformer with subsequent skidding onto the foundation.

Once the lifting system had been converted, we delivered the flywheel, weighing 78,500 kg, by road transport from Hamburg directly into the machine house under the lifting system.

The flywheel was offloaded and placed directly onto the foundation.

At the same time as the flywheel being installed, the generator was transported from the seaport to the construction site using a 20-axle transport configuration and set down.

Due to the short distance between the foundations of the flywheel and the generator, it was then transported by a 10-axle self-propelled transporter into the machine house.

Due to the limited space inside the building, our engineering department had to develop its own lifting lugs, which were used to unload the generator.
