Test facility


DHI Maritime Technology Evaluation Facility, located in Hundested, Denmark

The test facility conducts biological evaluations of maritime technologies. Due to the unique location of the test facility, high quality water is available from natural sources of fresh water and seawater. Fresh water is collected in lake Arresø and transported by lorry to the test facility. The water outside the test facility is brackish (approx. 18 PSU) and high saline test water is prepared by addition of brine to the natural brackish water. 

The test facility comprises six ballast retention tanks of 250 m3 each and one source tank of 750 m3. Testing can usually be conducted from the beginning of March to mid-December. The sampling of test water is accredited by DANAK (The Danish Accreditation Fund).
