Embodiment Construction

[0014] In the following description, numerous details are set forth in order to provide an understanding of the present invention. It will be apparent, however, to those skilled in the art that the invention may be practiced without these details and that many variations and modifications may be derived from the described embodiments.

[0015] figure 1 Shown is a marine vessel 100 having a reel or reel 104 for deploying a streamer 102 (or multiple streamers 102), wherein the streamer 102 is a cable-like structure with a number of electronic devices 103, the electronic devices 103 is used to conduct subsurface surveys of subterranean structures 114 beneath the seabed 112 . Hereinafter, the term "streamer" is intended to cover a streamer being towed by a marine vessel or a submarine cable laid on the seabed 112 .

[0016] Electronics 103 may include sensors, steering or navigation devices, air gun controllers (or other signal source controllers), positioning devices (eg, acous...

Abstract

A streamer or cable for use in subterranean surveying includes a communications link, a plurality of network nodes interconnected by the communications link, where each of the plurality of network nodes is configured to perform a self test to detect a fault condition of the corresponding network node, and bypass switches to bypass faulty one or more network nodes.

Description

technical field [0001] The present invention generally relates to providing a bypass switch to bypass a failed node or nodes in a streamer. Background technique [0002] A marine seismic streamer is a long cable-like structure that can be several kilometers long. The streamer includes an array of acoustic sensors (eg, geophones or hydrophones) and associated electronics along the length of the streamer. Acoustic sensors are used in marine seismic surveys. [0003] Typically, marine seismic surveys are conducted by vessels at sea towing many streamers. The streamer is deployed from the sea vessel, usually from the stern of the sea vessel. Each streamer is unwound from a reel or drum for deployment into the water. [0004] Electronic devices (including sensors and other devices) in the streamer are associated with network nodes in the streamer that are interconnected by one or more communication links. The network node includes a telemetry module that communicates via one...
