Directionally and Depth Steerable Seismic Source Array

摘要

A steerable seismic energy source (119) includes at least one float (107). The floatation device (107) includes a device for changing buoyancy thereof. A frame (115) is coupled to the at least one float. At least one seismic energy source (119) is suspended from the frame. At least one steering device (26) is coupled to the floatation device or the frame. The at least one steering device (26) includes at least one control surface and a control surface actuator coupled to the control surface. The actuator is configured to rotate the control surface to generate hydrodynamic lift at least in a vertical direction.
