Abstract
Apparatus, systems and methods associated with a pressure-balanced seismic sensor package are disclosed. One example of an apparatus can include a plurality of optical components, a sensor box enclosing the plurality of optical components, and a lid for the sensor box. The plurality of optical components, the sensor box, and the lid form a pressure-balanced seismic sensor package.
Claims37
An apparatus, comprising:
- a plurality of optical components;
- a sensor box with an interior to enclose the plurality of optical components;
- and
- a lid for the sensor box, wherein the plurality of optical components, the sensor box and the lid form a pressure-balanced seismic sensor package.
1 more element
A system, comprising:
- a first part of a pressure-balanced seismic sensor package comprising a plurality of optical components enclosed in a sensor box;
- a lid for the sensor box that includes at least one flexible component;
- and
- a second part of the pressure-balanced seismic sensor package comprising an optical hydrophone mechanically connected to an exterior of a wall of the sensor box.
1 more element
A system, comprising:
- a first part of a pressure-balanced seismic sensor package comprising a plurality of optical components enclosed in a sensor box, the sensor box comprising:
- a first compartment enclosing an optical accelerometer;
- and
- a second compartment enclosing interferometer optics and an optical splice shuttle;
- a lid for the sensor box that includes at least one flexible component;
- and
- a second part of the pressure-balanced seismic sensor package comprising an optical hydrophone mechanically connected to an exterior of a wall of the sensor box.
4 more elements
A method of forming a pressure-balanced seismic sensor package, comprising:
- filling a part of a free space of a first compartment of a sensor box surrounding an optical accelerometer with a mineral oil;
- filling a part of a free space of a second compartment of the sensor box surrounding interferometer optics and an optical splice shuttle with a thermally-reversible thermoplastic gel;
- and
- mechanically connecting a lid via first screw fasteners to a wall that encloses the first compartment and the second compartment, wherein the lid includes seal screw fittings.
1 more element
A method, comprising:
- detecting seismic signals in a body of water with a pressure-balanced optical seismic sensor package housed in a floodable sensor station;
- and
- communicating detected seismic signals from the pressure-balanced optical seismic sensor package along an optical cable coupled to the floodable sensor station.
