Abstract:
1. An apparatus comprising a body for connecting to a seismic streamer, the body defining at least one flow passage there through, and a diverter for selectively adjusting flow through the flow passage, the body comprising an external body, the external body having an inlet end, an outlet end, a longitudinal axis generally parallel to a streamer axis, and a diameter larger than a diameter of the streamer, wherein the at least one flow passage comprises at least one flow-through duct defined by the external body and an internal member selected from a portion of the streamer and a connector; wherein the body comprises the internal member extending from the inlet end to the outlet end, the flow-through duct fluidly connected to a normal flow outlet duct and a diversion flow outlet duct angled away from the longitudinal axis of the streamer, and including a controllable flow diversion member in at least one of the outlet ducts; and including a propulsion booster in the flow diversion duct to provide additional thrust to move a streamer.
