ABSTRACT:
A method and apparatus for providing shear waves in a marine environment in which a shear wave source penetrates the surface sediment of a water bottom. The shear wave generating source includes an actuator/reaction mass system mounted inside a structural ring of a housing section. A cross-shaped structure at the top of the apparatus serves as a passive reaction mass and as a moment arm support for reversibly motor driven propellers enclosed in shrouds at the outer ends of the structure. A thruster system provides dynamic positioning. The cross-shaped structure and housing section are connected by a structurally stiff member, such as a vertical tube. Pistons provide actuation against a reaction mass located within the housing structure, and motion of the housing structure generates shear waves which propagate in the subsurface formations.
