Abstract:
Disclosed are methods and systems for using tension feedback from steerable deflectors. In one example, a method may comprise: towing sensors streamers in a body of water from a survey vessel, wherein each of the sensor streamers comprises geophysical sensors at spaced apart locations; towing steerable deflectors in the body of water from the survey vessel, wherein the steerable deflectors are used to provide a lateral component of force to the sensors streamers as the steerable deflectors are towed through the body of water; turning the survey vessel; measuring tension at the steerable deflectors during the step of turning the survey vessel; and in response to the step of measuring tension, determining at least one of a reduced vessel operating speed, an increased vessel operating speed, a reduced angle of attack for at least one of the steerable deflectors, an increased angle of attack for at least one of the steerable, an increased vessel turn radius, or a decreased vessel turn radius.
