Abstract: A position controller capable of controlling the depth or lateral position of a towed array. The position controller comprises a tubular fuselage from which a pair of wings may be extended over a range of sweep angles between fully open and stowed positions. In fully or partly open positions, two wings present a positive angle of attack relative to the axis of the fuselage. In the stowed position, the wings are fully retracted into a wing receptacle within the fuselage for unfettered passage into and out of a submarine on the array deployment and retrieval handling system.

Abstract: A connection system for connecting external devices to specified locations on a marine seismic streamer. Inner collars are clamped to the cable at specified locations along its length. Each inner collar forms a circular race encircling the cable. An outer collar attached to an external device rotatably receives the inner collar and the encircled streamer in its bore to allow the streamer to rotate freely within the outer collar relative to the external device. The outer collar has an inner face bounding and defining the shape of the bore. The inner face is tapered from an intermediate position outward toward front and rear edges of the outer collar to form a bore that is wider at the front and rear edges than at the intermediate position. This flaring out of the bore provides the streamer three degrees of angular freedom to position itself within the bore.
