The Apach barrage ( French : Écluse d'Apach or Écluse d'Apach-Schengen ) with the Apach lock, the Schengen-Apach weir and the Schengen-Apach power station on the Moselle was completed by 1964 and is located in French and Luxembourg and German territory near the French community of Apach ( Opéch in Luxembourg ), right on the border triangle between Germany, Luxembourg and France. The Apach barrage is counted from the mouth of the Moselle near Koblenz , the 13th barrage with the 13th power plant on this body of water.

The lock was named after a pioneer of Moselle shipping, Pierre Ricard (1899–1956). Its name and relief decorate the lock tower.

history

The Moselle barrage in Koblenz was started as the first barrage in 1941. Due to the Second World War , the construction project was discontinued in 1944. From 1948 to 1951, the construction of the Koblenz barrage was completed under the direction of the French occupying forces . In the course of the further canalization of the Moselle from 1958 to 1964, the Moselle from Koblenz to Metz was made navigable and the Apach barrage was also implemented.

Between 2000 and 2006, the weir was automated by Gestion centralisée et coordonnée des barrages . In 2008 it was found that the gate valve of a weir was no longer fully functional. It was taken out of service for the time being. Further checks and repairs were carried out in 2009.

The development of the transport of goods shows an increasing tendency. In the eight years between 1993 and 2001, freight transport increased by more than 25%. Most of the cargo is carried by Dutch and Belgian ships, less than 10% by German ships and less than 1% by French or Luxembourg ships.

Barrages

A total of 28 barrages are now along the Moselle (see also: List of Moselle barrages ):

The barrage at Detzem has the greatest drop height of nine meters and the longest retention at 29 kilometers ; it is the only barrage on the Moselle with a lock canal.

From around the height of the lock gates of the Apach lock, the Moselle begins a common territory of Germany and Luxembourg (Moselle condominium ) over a length of around 36.5 km to Wasserbillig / Wasserbilligerbrück .

A few meters below the Apach barrage is the Moselle Bridge Schengen , built in 1958 ( Schengen ↔ Perl / N10 ↔ B 407 ).

Technical specifications

lock

The lock of the barrage is on the French bank near Apach on French territory. It is a lock with a rectangular lock chamber with a usable length of 172 meters and a width of 12 meters. The difference in altitude is 4.40 meters. Ships with a width of up to 11.40 meters can pass through the lock. The lock is separated from the weir by an island about 400 m long and 70 m wide, which is almost entirely on French territory. Only the lowest downstream tip of the island is in the area of ​​the German-Luxembourg condominium.

Weir

The weir adjoining the island, which is partly on Luxembourg and partly on French territory, can be adjusted to the water level of the Moselle so that the water level remains largely the same. The weir went into operation in 1962 and consists of three parts of 27.50 meters each. Segment slides are used in two parts and a flap slide in the third part .

The weir is managed by the French state waterway administration ( Voies navigables de France - VNF).

Hydroelectric power plant

There is a hydropower plant at each of the twelve barrages in Germany and Luxembourg. In France at another five locations. At the other barrages on the Moselle, the amount of water is not sufficient for the economically viable operation of a hydropower plant. The ten German hydropower plants on the Moselle have a total output of 180 megawatts. Because of the smaller amount of water, the Luxembourg and French hydropower plants have a lower output. All 17 hydropower plants have a total output of 209 megawatts. The dam targets and the 17 hydropower plants on the Moselle are controlled by the central control room of RWE Power AG at Fankel .

The Schengen – Apach run-of-river power plant (French: Centrale de Schengen-Apach ) located at the Apach barrage is located on Luxembourgish territory and seen from Schengen (upstream) on the right bank of the Moselle. The power plant is in the structural extension of the weir. It was built by Cefralux, a subsidiary of Société électrique de l'Our (SEO), and commissioned in 1995. Cefralux also operates the Schengen-Apach power plant. The existing head of 4.40 meters from the damming is used to convert up to 4.5 megawatts of power into electrical energy. By way of comparison: the Fankel run -of-river power plant , which is operated at the Fankel barrage around 180 km further down , and which went into operation in 1965, has an electrical output of up to 16.4 megawatts.

The Schengen – Apach power plant is a shaft power plant in which the energy is converted with two horizontally installed Kaplan turbines , each with three adjustable impellers. The Kaplan turbines each drive a synchronous generator via a gearbox . The power plant is built so that it can be completely flooded.

The Luxembourg road CR 152B ( Rue Robert Goebbels ) runs from Schengen to Contz-les-Bains (called D64F in France) right next to the Apach barrage power station .
