Abstract
It is proposed a seismic data acquisition device (400) intended to be placed on an ocean bottom floor, comprising a polymeric casing (412) defining a chamber that houses at least art of a data acquisition system (440, 444, 445); and a metallic device (414) in which the polymeric casing (412) is trapped, the metallic device (414) comprising two metallic beams (4141, 4142) that extend on opposite sides of the polymeric casing (412). It is also proposed a method for assembling such a device and a corresponding method for seabed seismic data acquisition.
Claims19
A seismic data acquisition device, also referred to as an ocean bottom node, intended to be placed on an ocean bottom floor, comprising:
- a polymeric inner casing defining an interior chamber that houses within at least part of a data acquisition system;
- and
- a metallic outer device in which the polymeric inner casing is trapped, the metallic outer device comprising two halves that are configured to be attached to each other with a fixation system, in a detachable manner, and each half includes metallic beams that extend on opposite sides of the polymeric inner casing.
A method for assembling a seismic data acquisition device, also referred to as an ocean bottom node, intended to be placed on an ocean bottom floor, the method comprising:
- providing a data acquisition system and a polymeric inner casing that houses at least part of the data acquisition system within an inner chamber of the polymeric inner casing;
- and
- providing a metallic outer device that comprises two halves that are configured to be attached to each other with a fixation system, in a detachable manner, and each half includes metallic beams adapted to extend on opposite sides of the polymeric inner casing;
- and
- imprisoning the polymeric inner casing into the metallic outer device.
