The agreement, which would breathe new life into a dormant  government-consented 50MW demonstration site off Frederikshavn, would see as many as six machines erected in 15-20 metres of water using UF's technology, a bucket-shaped foundation that is vacuum-sealed into the seabed and levelled using hundreds of built-in water jets before being fitted with a turbine.

"The offshore demonstration project is a very open concept right now," says UF managing director Torgeir Ramstad.
