GEOPHYSICAL SYSTEM FOR MONITORING AND MARINE SEISMIC SURVEY Russian patent published in 2016 - IPC G01V1/38 

FIELD: physics; geophysics.

SUBSTANCE: invention relates to systems for hydro- and geo-acoustic survey. The system includes surface equipment (1), as well as bottom-mounted switch (3) and multi-linear cable antennae with pressure sensors (5). The surface equipment (1) is connected to the switch (3) by an underwater main cable (4). All multi-linear cable antennae are connected to the switch (3) and their opposite ends are provided with anchor fixing elements (6). The anchor fixing elements (6) are connected to buoys (7) by buoy lines. Each buoy (7) is in the form of a container with drainage holes and a cover. Inside buoy (7) container there is a halyard storage in the form of a floating coil with a centre hole. A release passes through said centre hole, said release being fixed by lock rings on the side of the cover and the side of the lower part of the container. A buoy line connected to an anchor fixing element (6) passes through the lower lock ring and the release is electrically and tightly connected to the cable antenna.

EFFECT: broader functional capabilities, high reliability and enabling repeated deployment of the system with a long monitoring period.
