A system and method for deploying and retrieving streamers behind a tow vessel in a marine seismic array. Each streamer and attached lead-in cable are individually deployed and retrieved into and from the array, and are connected to adjacent lead-in cables with tag lines having a slidable latch mechanism attached to one or more ends of the tag lines. Each latch mechanism is slidable along a lead-in cable until is engages a tether head at a selected location which restricts further movement. Paravanes move the attached array transversely from the centerline of the vessel movement and retain tension on the tag lines. The system uniquely permits retrieval of a single lead-in cable and attached streamer without requiring retrieval of the entire seismic array. |
