METHOD OF INSTALLATION OF MARINE HYDROPHYSICAL POLYGON

摘要

FIELD: vessels and other watercrafts.;SUBSTANCE: initially, two (first and second) seismoacoustic stations, on which flat rudders are rigidly fixed, providing separation of bottom stations due to hydrodynamic forces arising due to movement of water, are lowered from the stern of the ship, from different sides. At the same time the ship bleeds cables connected to the first and the second stations, wound on the common coil of the third station. After development of the cable connecting the first and second stations, the ship reduces speed until the bottom touches the stations, after which a command is issued through hydroacoustic channel to drop rudders from the first and second stations, further, the vessel continues to drive until the cable length on the coil of the third station is equal to the cable length between the anchored first and second stations, after which the vessel drops the third station on the halyard from the stern until the bottom touches it, while simultaneously providing tension of the cables connecting the third station to the first and second stations. After these operations, buoyancy tied to ball is equipped with ballast and circuit breaker.;EFFECT: method is proposed for installation of marine hydrophysical polygon from ship, in which bottom stations are carried overboard, connected to each other by cable, wound on coils.;1 cl, 3 dwg
