Abstract: An acoustic array including a plurality of acoustic sensors positioned at predetermined telemetry points for measuring the acoustic energy from the surrounding environment. The acoustic sensors are each positioned within a fluid-filled pocket in the acoustic array, wherein each the various fluid-filled pockets are separated from each other by a section of solid fill buoyant material. The sections of solid fill material control the buoyancy of the acoustic array. The acoustic array is surrounded by a longitudinally extending outer hosewall which encloses the acoustic array and forms the fluid-filled pockets between the sections of solid fill material. A strength member is extended longitudinally throughout the length of the acoustic array to provide a load bearing mechanism for distributing longitudinal tensile loads applied to the acoustic array, while support spacers are situated within the acoustic array to provide radial support for the acoustic array. The acoustic array is formed of a lightweight and electrically passive structure which allows water to be used as the fill fluid for the pockets. Using water as the fill fluid provides an environmentally-safe fill fluid having buoyancy characteristics which are not significantly altered by its mixture with water from the surrounding environment should a rupture in the hosewall occur.

Abstract: A system for selectively tuning the buoyancy of a marine seismic streamer or underwater cable. Trimming weights are positioned along the streamer cable and can be integrated within a solid buoyancy member or can be located within an outer streamer sheath. The weights overcome the flotation forces provided by an internal buoyancy section to control the elevation of the streamer section. The outer streamer sheath can be opened to permit the removal or addition of trimming weights to the streamer section, and can be resealed to prevent water from intruding into the streamer interior. A single trimming weight can be positioned along the buoyancy member, or a plurality of trimming weights can be used. The trimming weights permit a tight buoyancy range to be accomplished without increasing water drag forces or noise as the streamer is towed.
Abstract translation: 一种用于选择性地调节海洋地震拖缆或水下电缆的浮力的系统。 修剪重物沿着拖缆缆线定位，并且可以集成在固体浮力构件内，或者可以位于外部拖缆护套内。 重量克服了由内部浮力部分提供的浮选力，以控制拖缆部分的高度。 外部拖缆护套可以打开，以允许移除或添加修剪重物到拖缆部分，并且可以重新密封以防止水侵入流光的内部。 可以沿着浮力部件定位单个修整重物，或者可以使用多个修剪重物。 修剪重量允许在拖缆拖动时不增加水拖力或噪音来实现紧密的浮力范围。

Abstract: A molded protective body member for seismic cable hydrophone and geophone sensors and their cable splice connections from underwater obstructions and pay-out and retrieval apparatus. The body member is a one piece polymeric member having interior cavities, risers and apertures. When in use, the body member is folded longitudinally in half around the seismic cable at a hydrophone or geophone splice joint and secured in place with recessable molded straps having threaded fasteners passing through each of the body halves thus clamping the body to the cable. At least one interior diametrical cavity is provided consistent with the type seismic cable sensor used. With the sensor and its associated cable and connector positioned within the protective body member, tie wraps are threaded through apertures along and adjacent the longitudinal edges of each half thus closing the interior of the body member. Cavities are also provided internally for placing lead weights. Lead weights may also be attached directly to the seismic cable within apertures provided within a portion of the body member.

Abstract: A towed body yaw angle sensor arrangement used to sense the angle between the axis of a tow fish and the flow of water. The water flow vector is used as the reference for correcting towed body yaw so that a magnetic compass in the towed body is aligned with the towed arrays streaming in the water flow. A yaw angle in the towed body with respect to the flow will cause errors for target bearing and skew the arrays relative to each other which will also cause errors. The flow sensor must be in the free flow off the towed body and ideally the sensing part is aligned with water current flow. Also provided is a method for sensing and correcting a yaw angle.

Abstract: A telemetry system for receiving data from large arrays of sensors, in which the sensors are located in an unprotected environment, is implemented using fiber optic components. Laser sources, located in a protected environment, transmit light through the boundary separating the protected environment from the unprotected one. The light is then split into a number of beams and fed to electro-optical modulators, where it is modulated in response to electrical signals received from the sensors. The modulated light signals are then wavelength-division multiplexed and transmitted back through the environment boundary, where they are amplified, demultiplexed and converted to electrical signals. Multiplexing reduces the number of boundary penetrations, and the use of highly stable electro-optical modulators eliminates the need for signal conditioning electronics at each sensor. This optical approach is particularly beneficial in an underwater application, such as a submarine receiving data from a large array of acoustic sensors, where it is desired that hull penetrations be minimized and the underwater components be highly reliable and stable.
Abstract translation: 用于从大型传感器阵列接收数据的遥测系统使用光纤组件实现传感器位于未受保护环境中的数据。 位于受保护环境的激光源通过将受保护的环境与未受保护的环境分开的边界传递光。 然后将光分离成多个光束并馈送到电光调制器，其中响应于从传感器接收的电信号进行调制。 调制的光信号然后被波分复用并通过环境边界传回，在那里被放大，解复用并转换成电信号。 复用减少了边界穿透的数量，并且使用高度稳定的电光调制器消除了在每个传感器处对信号调理电路的需要。 这种光学方法在诸如海底接收来自大量声学传感器的数据的水下应用中是特别有益的，其中希望船体穿透被最小化并且水下部件是高度可靠和稳定的。

Abstract: Ocean bottom seismic cables are subject to rolling motions due to seismic wave fields and current action which cause poor receiver ground-coupling and signal distortion, particularly along the cross-line and vertical axes. Two multi-axial receivers are mounted on opposite sides of the cable in a single cluster. When the cable rolls, the axial response of one receiver of the cluster cancels the axial response of the other receiver of that cluster.

Abstract: A self-powered towed underwater sensor is provided. The sensor has a shied casing which encloses an electric generator. The generator is connected to an impeller that is located at the midpoint of the casing. The impeller is covered by a shroud which minimizes the disturbance of the water by the impeller. The casing contains a shield which absorbs electromagnetic radiation produced by the generator. The shield is placed around the generator. A towed cable is connected to the forward end of the casing. The towed cable is made of a material having a high tensile strength to facilitate towing. A fiber optic cable is located within the towed cable and runs the length of the cable, specifically for transmission of received data from the attached sensor to the towing craft. The use of fiber optics prevents interference by electromagnetic radiation in the environment through which the cable passes, and there is no power lead that could conduct interference into the array.
