Abstract

An ever increasing degree of accuracy is required in positioning for 3D marine seismic surveys. Accuracy between the vessel and the streamer tail is significantly impaired when the only means of positioning are compasses placed along the streamer. This problem has been partially solved by the use of radiopositioned (Syledis) tail buoys. However, there remains some uncertainty as to the position of the streamer tail because the end of the streamer is connected to the tail buoy by a tail rope of significant length (to prevent noise on the hydrophones) and for which the bearing is unknown (owing to currents different from those affecting the streamer).
