Dock C, Maritime testing facility in Kiel, Germany

Dock C, known as the Druckdock, was a floating dock with an integrated pressure chamber at the Kiel naval arsenal. It was built by Flender-Werke Lübeck in 1967 so that submarines could be tested under simulated diving depths while crew and test personnel stayed on board. The dock was sold for scrap in August 2012 and no longer exists.

The facility was built in 1967 by Flender-Werke Lübeck and served for decades as a submarine testing site. It was decommissioned in 2012, ending its active operational phase.

Dock C was the only pressure dock of its kind in the Western world, so NATO partner navies used it for their own submarines. The last boat docked was the Norwegian Utstein, leak-tested until 18 March 2011. No comparable facility is documented in the former Eastern Bloc.

Dock C no longer exists: it was sold in August 2012 for 1.35 million euros and scrapped at Aliağa, Turkey, after the Greek tug Pantodynamos left the Marinearsenal in Kiel on 15 August 2012. Visitors to the naval arsenal site today will not find the floating dock there.
