Title:
STEERING SYSTEM AND METHOD FOR USE IN SEISMIC SURVEY APPLICATIONS
Document Type and Number:
WIPO Patent Application WO/2010/083003
Kind Code:
A3
Abstract:
A technique facilitates the steering of seismic survey related devices during seismic survey applications. A steering device is provided with a wing pivotably mounted to a body via a pivot member. As the steering device is moved through a liquid, the liquid acts against the wing and creates a torque about the pivot member which varies according to the angle of attack of the steering device. The steering device further comprises at least one feature designed to change the torque that would otherwise act on the pivot member.
