ABSTRACT:
Method for transporting an offshore tower to a desired deepwater site and for erecting the tower to an upright position on the submarine floor at that site. Initially, the intended base end of the tower is supported on a first barge, and the intended top end is supported on a second barge. The barges are then towed to the deepwater site. At the site, the tower is launched by first mutually separating the barges through the application of substantially horizontal and oppositely directed forces, while maintaining one tower end substantially stationary with respect to its supporting barge, and permitting the other tower end to slide off of the other barge. Therefor, the other tower end is moved off of the other barge.
