Abstract
A method and apparatus are disclosed to transport and position a drilling rig over dry land, marshland and water. Surface effect vehicles having drive and positioning means that develop thrust against the surface over which they travel are used to lift and transport a drilling barge, after which they may be used as support and supply vehicles. Provision is made to adjust variable cargo loads so as to balance the assembled unit during transport.
