Abstract: There are described methods and systems for deploying optical fiber within a conduit. In one aspect, an optical fiber injector comprising a pressure vessel having a fluid inlet and a fluid outlet. The fluid outlet is engaged with an open end of the conduit. A length of optical fiber is provided within the pressure vessel. The optical fiber is then jetted into the conduit by injecting a fluid into the pressure vessel via the fluid inlet. The optical fiber injector is configured such that the fluid is directed from the fluid inlet to the fluid outlet, and urges the optical fiber to move through the conduit, thereby deploying the optical fiber within the conduit. In a further aspect, there is provided a modular assembly comprising a pipeline and a line of two or more conduits arranged end-to-end. Each pair of opposing ends of adjacent conduits is connected together by a separate splice box. The line is positioned along and adjacent to a length of the pipeline.

Abstract: A sound baffle device for use with an acoustic sensor deployed in a housing by a deployment line is disclosed. The sound baffle device comprises a radially extending baffle plate and an affixing mechanism for affixing the baffle plate to the deployment line. The baffle plate is configured to reduce acoustic transmission between a first zone of the housing on one side of the baffle plate and a second zone of the housing on an opposite side of the baffle plate. A system for detecting acoustic signals in a zone of interest in a housing is also disclosed. The system comprises an acoustic sensor positioned in the zone of interest and one or more than one sound baffle positioned between the zone of interest and a first zone of the housing. The sound baffle is configured to reduce acoustic transmission from the first zone to the zone of interest. The sound baffle provides some level of acoustic isolation between two zones on either side of the baffle plate thereby aiding detection and identification of acoustic signals in the zone of interest by reducing transmission of acoustic signals from the first zone to the zone of interest.

Abstract translation: 公开了一种用于通过部署线路部署在壳体中的声学传感器使用的隔音装置。 隔音装置包括径向延伸的挡板和用于将挡板固定到展开线的固定机构。 所述挡板被构造成减小所述挡板的一侧上的所述壳体的第一区域与所述挡板相对侧上的所述壳体的第二区域之间的声传播。 还公开了一种用于检测壳体中感兴趣区域中的声信号的系统。 该系统包括位于感兴趣区域中的声学传感器和位于感兴趣区域和壳体的第一区域之间的一个或多个声音挡板。 声音挡板被配置为减少从第一区域到感兴趣区域的声学传播。 隔音板在挡板两侧的两个区域之间提供一定程度的声学隔离，从而通过减少从第一区域到感兴趣区域的声信号的传输来帮助检测和识别感兴趣区域中的声信号。
