Abstract
Marine vibrators and marine vibrator systems are provided herein having one or more remotely located components. An exemplary marine vibrator includes at least one electromagnetic transducer, a control-monitoring electronics system, and a frame, where the at least one electromagnetic transducer is at least partially within the frame. The at least one electromagnetic transducer receives alternating current (AC) electrical power from one or more power amplifiers, via at least one umbilical that connects the at least one electromagnetic transducer and the one or more power amplifiers, where the one or more power amplifiers are remotely located from the marine vibrator.
Claims20
A marine vibrator, comprising:
- at least one electromagnetic transducer;
- a control-monitoring electronics system;
- and
- a frame, wherein the at least one electromagnetic transducer is at least partially within the frame;
- wherein the at least one electromagnetic transducer receives alternating current (AC) electrical power from one or more power amplifiers, via at least one umbilical that connects the at least one electromagnetic transducer and the one or more power amplifiers, wherein the one or more power amplifiers are remotely located from the marine vibrator.
A marine vibrator system, comprising:
- one or more power amplifiers;
- a control-monitoring electronics system;
- and
- at least one marine vibrator comprising:
- at least one electromagnetic transducer;
- and
- a frame, wherein the at least one electromagnetic transducer is at least partially within the frame;
- wherein at least one of the one or more power amplifiers and at least a portion of the control-monitoring electronics system are remotely located from the at least one marine vibrator, and wherein the one or more power amplifiers transmit alternating current (AC) electrical power to the at least one electromagnetic transducer, via at least one umbilical that connects the at least one electromagnetic transducer to at least one of the one or more power amplifiers.
A marine vibrator, comprising:
- at least one electromagnetic transducer comprising:
- at least one piston;
- at least one moving armature assembly that drives the at least one piston based on alternating current (AC) electrical power received from one or more power amplifiers associated with the marine vibrator;
- a first set of sensors that measures an acceleration of the at least one piston, and
- a second set of sensors that measures an acceleration of a stator of the at least one moving armature assembly;
- wherein the acceleration of the at least one piston relative to the acceleration of the stator is controlled, in substantially real time, by adjusting the AC electrical power based at least in part on the accelerations measured by the first set of sensors and the second set of sensors.
