    Abstract: A quintuplex mud pump has a crankshaft supported in the pump by external main bearings. The crankshaft has five eccentric sheaves, two internal main bearing sheaves, and two bull gears. Each of the main bearing sheaves supports the crankshaft by a main bearing. One main bearing sheave is disposed between second and third eccentric sheaves, while the other main bearing sheave disposed between third and fourth eccentric sheaves. One bull gear is disposed between the first and second eccentric sheaves, while the second bull gear is disposed between fourth and fifth eccentric sheaves. A pinion shaft has pinion gears interfacing with the crankshaft's bull gears. Connecting rods on the eccentric sheaves use roller bearings and transfer rotational movement of the crankshaft to pistons of the pump's fluid assembly.

    Abstract: A system and method are provided for detecting an acoustic signal in the presence of flow noise produced by the turbulent flow field that develops about a hosewall of a towed array. Pressure is sensed with pressure sensors at two diametrically-opposed locations at the surface of the hosewall over a period of time. The sensed pressure signals are used to generate an ensemble-averaged cross-spectra which effectively cancels out the flow noise while retaining the acoustic signal associated with a possible target of interest.

    Abstract: A load limiting break away arrangement for a subsea umbilical includes telescoping inner and outer bodies. The inner body includes multiple cross-bored holes; the outer body has slotted openings on its top and bottom sides. A shearing blade is positioned at one end of a top slot of the outer body. Individual umbilical tubes pass through a bottom slot of the outer body, through individual holes in the inner body and out a top slot of the outer body for attachment to multiple quick connect couplers on an umbilical termination head of an Umbilical Termination Assembly (UTA) and of an Electro-Hydraulic Distribution Module (EHDM). Tension resistant actuation members run between the UTA and EHDM so that when a snag of an umbilical occurs, the inner and outer bodies are pulled apart and the tubes are severed one by one by the blade of the outer body.

    Abstract: A rotary joint between a towed array and its towing vessel is provided having a drive plate, shaft and rotor attached to the towed array payout and take-in stowage drum and rotating with the drum. A thrust washer and bearing provide a rotating mechanical connection between these rotating components and the stationary housing and connector portions of the joint. The housing is fixed within the vessel and has an internal stator surrounding, and in electrical communication with the rotor. Electrical feeds from the towed array are connected to contact rings within the rotor, and the stator includes spring loaded pins in radial electrical contact with the rings as the rings rotate with the rotor. Electrical leads from the pins pass through the housing to the connector which is connected to the vessel's signal processing systems. In addition, the housing contains a pressure compensator within a passageway between the interior and exterior of the joint. The compensator has a piston sealed in the passageway and springs are provided to either side of the piston, such that the opposed expansion and contraction of the springs maintain a pressure differential over the piston.
