HYDRODYNAMIC LOW TRAINING SYSTEM FOR TOWING SEISMIC FLUTES.

摘要

The invention relates to a set of devices which makes it possible to reduce the towing forces of a large number of marine seismic streamers. It consists in producing fairing elements (01) fixable to the pulling cable (06) of the divergent, these profiled fairings integrate the supply wires (16, 17) of the individual tugs (22) as well as the conductors which convey the signals. of seismic. Making the connection of these fairing elements to bypass devices (09) which make it possible to mechanically and electrically connect the tugs via a leash (12) or directly the seismic flutes (29). A set of immersible floats (22) makes it possible to compensate for the weight of the traction cable (06). The realization of a propulsion system (25) connected to the divergent by canceling its drag reduces the rear offset relative to the seismic boat.
