METHOD AND SYSTEM FOR CONTROLLING STREAMERS

摘要

A method and system for controlling the shape and separation of an arrangement of streamers towed behind a survey vessel (10). Each streamer is steered laterally by lateral steering devices (16) positioned along its length at specific nodes. Each streamer is driven by its lateral steering devices to achieve a specified separation from a neighboring streamer. One of these actual streamers, used as a reference by the other actual streamers, is steered to achieve a specified separation from an imaginary, or ghost, streamer virtually towed with the actual streamers.
