Wind turbine installation vessel

[3] Some vessels use the thrusters in dynamic positioning (without jacking up) to keep the vibrating pile driver steady when installing foundations.

[4] Some may carry five modern wind turbines and lift 700 tonnes 125 metres (410 ft) above deck.

[11] A supplement to crane-equipped WTIVs can be crane-less feeder vessels with motion compensation.

[24] The Jones Act makes it much more difficult to install offshore wind, introducing complications of transferring parts between ships and raising costs.
