Description
Summary:In the deployed MSS, seismic motion is sensed and converted into a digital data stream by the Borehole Instrumentation Package (BIP). The data is transmitted over a single Electro-Mechanical (EM) coaxial conductor cable to the Bottom Processing Package (BPP). The BPP continuously acquires and stores the data in real-time for up to 45 days. A hydroacoustic sensor is also located on the BPP with its data acquired and stored synchronously with the seismic data. Power to operate the BIP and BPP electronics is provided by two silver-zinc batteries located on the BBP. The BPP is deployed and retrieved by the mooring system, which is referred to as the Installation, Retrieval and Re-deployment (IRR) hardware. The system is designed to operate in water depths of up to 6,000 meters. This report documents and defines the system developed under this contract and its implementation. Elements of this report include: An overview and summary of the development and deployment including accomplishments, lessons learned, and recommendations for future efforts; A description of the operational and functional requirements of the MSS; A description of all Gould (Contractor) designed and fabricated equipment; A description of the set-up, test and operation requirements of the Gould developed equipment; A description of the system deployment and recovery; and A post-deployment performance analysis of the Gould designed equipment.
