Abstract
A sensor streamer stretch section. At least some of the example embodiments are methods including measuring at least one parameter related to noise while towing the sensor streamer through a body of water with a towing vessel, and adjusting at least one of a spring constant and a damping coefficient of a stretch section disposed proximate the sensor streamer such that the measured parameter is minimized.
Claims17
A method for reducing noise in a sensor streamer, comprising:
- measuring at least one parameter related to noise while towing the sensor streamer through a body of water with a towing vessel;
- and during the towing
- adjusting at least one of a spring constant and a damping coefficient of a stretch section disposed proximate the sensor streamer such that the measured parameter is minimized.
A method comprising:
- towing a sensor streamer through a body of water with a tow vessel;
- measuring a parameter related to noise associated with the sensor streamer, the measuring during the towing;
- and
- adjusting parameters of a stretch section coupled to the sensor streamer, the adjusting, during the towing, by changing at least one selected from the group comprising:
- a spring constant of the stretch section;
- and a damping coefficient of the stretch section.
