CTV

Crew Transfer Vessel — a fast, small catamaran used to transport maintenance technicians from port to offshore wind turbines and back on a daily basis. CTVs transfer personnel by pushing directly against the turbine access platform using fendering (bump-and-transfer method). They typically carry 12 technicians, operate at speeds of 25–35 knots, and work within 50–80 nautical miles of port. CTV deck crew require STCW Basic Safety Training and an ENG1 seafarers medical.
