Abstract
Techniques are disclosed relating to marine geophysical prospecting. According to some embodiments, a survey vessel may tow a streamer through a body of water. If the streamer needs to be maintained (e.g., cleaned, repaired, or serviced), a second vessel may lift the streamer out of the water for this purpose. Techniques are disclosed that are relevant to the handling of protruding members (such as streamer steering devices) on the streamer.
