Abstract
Disclosed are methods and systems for enabling anti-twist functionality in marine geophysical streamers. An embodiment discloses a method comprising: towing a streamer behind a survey vessel in a body of water, wherein the streamer comprises rotation sensors and streamer rotation devices; receiving data from at least one rotation sensor indicative of streamer twist; and rotating a portion of the streamer with at least one streamer rotation device to reduce the streamer twist based, at least in part on the data.
