Abstract

One of the significant factors affecting the operation of fiber-optic towed streamers is towing noise, which is caused by the varying speed of the towing vessel and the resistance of the buoys and the floating anchor of the streamer during towing. In this study, a method for compensating the towing noise of a fiber-optic streamer is proposed. The proposed method entails independent measurement of the towing noise using an additional interferometer and subtraction of its signal from the signals of the fiber-optic hydrophones of the streamer. The experimental results show that the towing noise can be reduced to 70% in the frequency range of 0–40 Hz.
