System and method for deployment of seismic data recorders

摘要

A system and method for deployment of a plurality of seismic recorder assemblies from a survey vessel on the ocean bottom is disclosed. The seismic recorder assemblies are self contained, autonomous nodal devices which are capable of receiving and recording reflected seismic energy and storing the data locally while operating for an extended period of time. The assemblies each have two or more attachment points for the connection of separate connecting cable segments.

主权项

1. A seismic data recorder array configured to be deployed on a bottom of a body of water, the seismic data recorder array comprising a plurality of individually powered autonomous seismic data recorders reversibly interconnected by separate mechanical connecting segments, each adjacent pair of seismic data recorders being reversibly connected by a corresponding mechanical connecting segment, each such mechanical connecting segment containing no electrical or optical communication means or electrical or optical conductors, and wherein adjacent connecting segments are not attached to one another and the seismic data recorders are configured not to communicate with one another when deployed in the array on the bottom of the body of water.
