Abstract: An internal device for use in an underwater cable may comprise a body having an outer periphery, body being mountable inside the cable with the cable surrounding the outer periphery of the body. The body may include a cutaway portion, a slot, or a dovetail joint. An underwater cable arrangement may comprise an underwater cable and an internal device disposed in the cable with the cable surrounding the device. The underwater cable may include a stress member connected to the internal device by an interference fit or the internal device may include a slot for receiving the stress member. A method of connecting a stress member of an under water cable to an internal device includes forming an interference fit between a region of increased diameter of the stress member and the internal device.

Abstract: A variable buoyancy cable is provided. In one aspect, the variable buoyancy cable includes a flexible sleeve that has an inner wall and an outer wall. A core is positioned in the sleeve and has a longitudinally disposed external channel with opposing first and second sidewalls. The channel and the inner wall of the flexible sleeve define a fluid passage for receiving a fluid to affect the buoyancy of the variable buoyancy cable. A slackened utility line is positioned in the channel and a fluid supply is coupled to the flexible sleeve and is operable to move fluid into and out of the fluid passage to selectively affect the buoyancy of the variable buoyancy cable. The core protects utility lines in the cable from damage due to ambient pressure and/or bending during deployment and retrieval. The buoyancy may be varied to suit various water conditions and mission requirements.

Abstract: A low friction surface is provided to hose-shaped acoustic envelopes for towed sonar arrays. The low friction surface permits multiple envelopes that are in intimate, parallel contact or that are crossed-over one another, to slide easily relative to one another, enhancing their deployment. The low friction surface is accomplished by blending particles of a low friction material with a base material. The mixture is heat extruded into pellets and the pellets are heat extruded into a hose of desired size. The exterior surface of the resulting hose is then subject to axially aligned abrasion to both expose the particles close to the exterior surface of the hose, and to create axially aligned micro-grooves in this surface. The micro-grooves allow water to enter and lubricate the boundary that is present, which is typically either another hose surface or the metal or other surface of an array deployment vehicle. The envelope material further provides improved damping of array hydrodynamic self noise for certain acoustic environments.

Abstract: An arcuate or flat ferroelectric sensor is incorporated in a seismic streamer. The structure comprises two half-cylinders which are mounted together around a cable. The half-cylinders are coupled together by bolts or pins or any other appropriate means. Each half-cylinder defines a well into which a sensor is mounted. With the sensor in place, the structure is covered over with a sound-transparent material to receive an acoustic signal into the sensor. Electrical leads from the sensor are directed through ports in the half-cylinders, and the leads are connected together to provide a composite sensed signal to the cable in analog form. The sensor in each half-cylinder is a single element hydrophone that, when connected to a sensor in a complementary half cylinder in series or in parallel, forms an acceleration cancelling hydrophone.

Abstract: An interlink for connecting hydrophone elements to allow a single sensing ber to transition from a first hydrophone element, across the interlink, to a second hydrophone element. The interlink satisfies the dual objective of protecting the sensing fiber during handling system stresses, while desensitizing the sensing fiber along the interlink during operational periods. The interlink has a first end connected to the first hydrophone element, and a second end connected to the second hydrophone element. Between the interlink ends is at least one turn, and the distance traveled along the interlink turns is greater than the linear distance between the interlink ends. The interlink contains a groove that traverses the entire interlink length. Sensing fiber is wound off the first hydrophone element, into the interlink groove that follows the interlink turns, and onto the second hydrophone element. The turns allow the interlink to expand as desired, but the interlink design and material must be chosen to provide sufficient elasticity to return to original form. The sensing fiber may be epoxied to the interlink for greater connectivity.

Abstract: A hydrophone interlink that connects hydrophone elements and allows a sin sensing fiber to transition between hydrophone elements. The interlink has an outer-structure and a contained element. The outer-structure connects the hydrophone elements and has at least one turn such that the distance traveled along the turns exceeds the linear distance between hydrophone elements. The outer-structure material and shape allow temporary interlink stretching and compression during passes through handling sheaves, with memory to allow the interlink to return to its original shape. The outer-structure contains a groove on either end to transition the sensing fiber between the hydrophone elements and the contained element. The contained element is open cell foam that fills the hollow core of the outer-structure. The sensing fiber transitions from a first hydrophone element to immediately enter the feed at the interlink first outer-structure end, whereupon the fiber transitions to the open cell foam and follows the interlink outer-structure structure while remaining on the foam.

Abstract: A non-fluid-filled streamer cable or towed array for performing seismic surveys in water-covered areas includes a plurality of serially coupled active cable sections. Each active cable section includes an electromechanical cable that contains a single central strain member. A wire bundle is placed around the central strain member for transporting electrical power and data through the active section and an inner protective jacket is formed around the central strain member and wire bundle. A foam material is extruded around the inner protective jacket to provide a predetermined buoyancy to the fully assembled active cable section and an outer protective jacket is formed around the foam jacket. A potting compound is formed between, and bonds to, the inner protective jacket and outer protective jacket to provide a water block at each hydrophone location.

Abstract: A technique and a system provide control and monitoring of devices external to a marine seismic streamer by segmenting the conductor to which the external devices are coupled. The module which connects sections of the seismic data telemetry cable is modified to include a switch. The switch is controlled by a command signal on the seismic data telemetry cable to segment the twisted pair bus into a plurality of dedicated busses, each dedicated to a subset of the external devices, such as one or two such devices. In this way, the external devices can be communicated with in parallel, rather than in series as in conventional systems.
