She has the capacity for ten wind turbines at a time. The whole ship can be jacked up out of the sea on her six legs, to provide a stable platform when installing wind turbines. The jacking system uses hydraulics. [4] She can raise herself between 3 metres (10 ft) and 46 metres (151 ft) above the sea. [2]
Some may carry five modern wind turbines and lift 700 tonnes 125 metres (410 ft) above deck. [5] [6] A vessel can cost [7] $335 million, or $220,000 per day. [8] A 3-year leasing may cost €90 million. [9] The fleet of 16 vessels are scheduled to expand to 23 vessels by 2023, of which seven can handle the largest turbines.
