ABSTRACT:
In seismic surveys at sea, with seismic devices, especially sources of seismic energy being towed behind a vessel and kept at a mutual configuration relative to each other, and with the devices being suspended from a buoyancy member (1) mechanical structure of the equipment permits undesirable forces which influence the sources of seismic energy (3), especially during firing, to be absorbed. Mutually arranged flexible, resilient members (4) are provided between the suspension line of the seismic devices (3) and the seismic devices (3) and/or between the seismic devices. Seismic devices are supported on two or more rigid fastening members (5) and flexible resilient members (4) extend between the fastening members and the suspension line. The flexible resilient members (4) preferably extend in a curved path between the fastening members (5) and the members together form an integrated unit.
