Method and system for adjusting vessel turn time with tension feedback

摘要

[0035] Disclosed are methods and systems for using tension feedback from steerable deflectors to adjust vessel turn time. In one example, a maximum tension for a second steerable first towed on a first side of the survey vessel may be determined. A radius of a turn of the vessel at a preselected speed may further be selected such that the tension on the first steerable deflector is less than the maximum tension. The vessel may be turned while moving at the preselected speed, wherein the turning of the vessel has the selected radius. Tension may be measured on the first steerable deflector during the step of turning the vessel, / :90 50 50 25 50 50 90 7 45 45 45 45 60 96 96 60 85 82 65 70 67 82 85 80 30 30 30 30 40 140 40 40 30 30 30 30 30 r30 30 r30
