Abstract: A marine seismic streamer includes plural concentrators, plural segments interposed with the plural concentrators so that a concentrator of the plural concentrators is sandwiched between two segments of the plural segments, a first high-voltage rail HV1 that extends along the plural concentrators and the plural segments, and a second high-voltage rail HV2 that extends along the plural concentrators and the plural segments. In each given concentrator i of the plural concentrators, there is a first switch SW1 placed along one of the first high-voltage rail HV1 and the second high-voltage rail HV2, a second switch SW2 placed between the first high-voltage rail HV1 and the second high-voltage rail HV2, a first local controller implemented in hardware, and a second local controller implemented in a combination of hardware and software, and having an operating system, the first local controller being separated from the second local controller.

Abstract: A method for automatically propagating a voltage along a marine seismic streamer, the method including detecting, at an ith concentrator of the streamer, a first voltage applied at a first high-voltage rail HV1; detecting, at the ith concentrator of the streamer, a second voltage applied at a second high-voltage rail HV2, the first and second high-voltage rails extend over the entire streamer; checking a predetermined condition at a first local controller of the ith concentrator; and closing a first switch SW1, which propagates the first high-voltage rail HV1, when the predetermined condition is satisfied.
