Maritime Exploration Hall
The 1,300 m² Maritime Exploration Hall serves to test new robotic technologies on and under water. Everyday missions of the offshore industry are simulated, maneuvers are carried out and skills of future systems are demonstrated. The infrastructure comprises a large basin, two separate test basins, a virtual reality laboratory, a pressure chamber as well as complete technical equipment from cranes up to laboratories.
Co-financing
The Federal State of Bremen invested 3.1 million Euros from EFRE funds in the new building and the Maritime Exploration Hall, 4 million Euros are co-financed by the DFKI itself.
Technical infrastructure at a glance:
- a 23 m x 19 m x 8 m test basin, including mechanical infrastructure
- 3.4 million liters of saltwater (18 g of salt per liter)
- crane systems (12.5 t and 250 kgs) to immerse systems and test objects in the basin
- a window close to ground level that allows observers to look into the large basin
- space for two 20’ containers near the basin and a spacious logistics area in front of the building
- separate test basins
- a 5 m x 4 m x 2.2 m glass tank containing 40,000 liters of water with three glass walls for optimum observation of test runs
- a 3.4 m x 2.6 m x 2.2 m black tank that can be covered to shield it against external light and permitting control of the water turbidity
- a pressure chamber
- water pressure corresponding to a depth of 6,000 m (600 bar)
- a virtual reality lab as an immersive, interactive 3D test environment
- projection surface consisting of seven elements with an overall area of 21.6 m²
- interaction in a virtual test environment by means of a CyberTouch data glove
- workshops and workstations
Large basin
The heart of the facility is a large basin filled with saltwater, measuring 23 m x 19 m x 8 m. With 3.4 million liters of saltwater research conditions are created which are controllable and observable and are not subject to changes in weather. A 2 m x 3 m window close to ground level allows observers to look from the foyer of the new DFKI building in Robert-Hooke-Straße 1 into the large basin.
Separate test basins
Moreover, the Maritime Exploration Hall comprises a glass tank containing 40.000 liters with three glass walls for optimum oberservation of test runs. A further test basin, the so-called black tank, can be covered to shield it against external light and permitting control of the water turbidity. A gentry crane with a lifting capacity of 500 kgs spans the whole basin area.
