Abstract

See full text

Streamer redundancy. At least some illustrative embodiments are methods including: in a streamer towed by a survey vessel, sensing a first interconnection of a daisy chain the first interconnection between a first networked unit and a second networked unit, wherein the first networked unit and the second networked unit comprise a portion of a plurality of networked units; and determining that a fault condition exists on the first interconnection in response to the sensing; disabling the first interconnection responsive to the fault condition; enabling a second interconnection responsive to the fault condition, wherein the second interconnection couples the first networked unit and a third networked unit of the plurality of networked units and wherein the second interconnection does not couple to the second networked unit; and reporting information indicative of the fault condition to the survey vessel via the second networked unit.
