Directionally and depth steerable seismic source array

摘要

PGS-09-28US Abstract [0035] A steerable seismic energy source includes at least one float. The floatation device includes a device for changing buoyancy thereof. A frame is coupled to the at least one float. At least one seismic energy source is suspended from the frame. At least one steering device is coupled to the floatation device or the frame. The at least one steering device 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. 110a 121 109 121 109 106 109 108 10 108 11l 108 122 113 112 114 114/ 114 114/ 1114 115 114/ 116 1 119 119 119 119 119 119 119
