Abstract

A method for towing a sensor streamer array in a body of water includes towing a plurality of sensor streamers behind a vessel in the water, measuring tension at a plurality of positions along the array and determining at least one of an optimum operating speed for the vessel, when the streamers and associated towing equipment have become affected by marine debris so as to require cleaning, and an optimum angle of attack of at least one paravane in the towing equipment.
