摘要： An improved acoustic source array system is provided by the invention to generate acoustic signals underwater. The system has an array of acoustic signal sources, such as air guns, towable while underwater behind a surface vessel. The array includes a plurality of these sources, and spreader bar assemblies including these sources. The sources are attached by these assemblies at predetermined separation distances in the array. The spreader bar assemblies provide manifolds for storing and regulating energy, such as compressed air, to operate the sources. The array is connected to the vessel by an umbilical. The sources are controlled by a shipboard controller for firing the sources to provide acoustic signals underwater at selected times. The array may be towed from the ship with the flat side of the array assuming an angle of approximately 45.degree. or less with respect to a vertical axis. The flat side of the array includes a horizontal axis that is normal to the direction of tow. A drum on the ship stows the spreader bar assembles on flanges of the drum in successive layers and enables the array to be deployed.
摘要翻译： 本发明提供改进的声源阵列系统以在水下产生声信号。 该系统具有阵列的声信号源，例如空气枪，在水下船只后方可拖曳。 该阵列包括多个这些源，以及包括这些源的扩展器杆组件。 源以这些组件以阵列中预定的间隔距离连接。 扩张杆组件提供用于存储和调节能量（例如压缩空气）的歧管以操作源。 阵列通过脐带连接到血管。 来源由船上控制器控制，用于在选定的时间点火源提供水声信号。 阵列可以从船舶的平坦侧被拖曳，相对于垂直轴线呈大约45°或更小的角度。 阵列的平坦侧面包括垂直于丝束方向的水平轴线。 船上的滚筒将连续的层上的吊具杆装在鼓的凸缘上，并使阵列能够部署。

摘要： A floatation device for marine seismic energy sources. The floatation device includes one or more tubular members and a plurality of couplings for sealing and coupling the tubular members to one another. The couplings include an air valve for filling the tubular members with air. One or more marine seismic energy sources are preferably coupled to and supported by the floatation device.
