Wing for wide tow of geophysical survey sources

摘要

Techniques are disclosed relating to wide towing of marine survey signal sources. In one embodiment, an apparatus includes a signal source and a wing coupled to the signal source. In this embodiment, the wing is configured to impart a force to the signal source when towed through a body of water by a survey vessel. In this embodiment, the force includes a lateral component and a vertical component. The wing may be configured to impart the force based on a shape of the wing and an orientation of the wing. The wing may extend over at least a third of a length of a keel of the apparatus. At least a majority of a top surface of the wing may be oriented within 20 degrees of parallel to a surface of the body of water. The wing may include a plurality of wing sections.

主权项

1. An apparatus, comprising:
a keel; a signal source coupled to a bottom portion of the keel; and a wing coupled to a top portion of the keel and configured, when towed by a survey vessel through a body of water, to impart a force having lateral and vertical components that result from movement of the wing through the body of water; wherein the wing includes a plurality of wing sections, wherein at least one of the plurality of wing sections is configured to separately rotate about a pivot point that couples the at least one of the wing sections to the keel.
