Abstract
A semi-dry marine seismic streamer cable (5) consists of a number of connected streamer cable sections (5a) which each comprises a mechanical jacket (10) surrounding a hollow core (11) enclosing seismic sensor (15) and signal transfer (16) means. Elongated axial stress elements (18) for transmitting axial loads and a radial reinforcement member (12) for relieving radial loads are provided in the jacket (10). The core (11) is filled with a fluid or a fluid-saturated foam and the sensor means (15) are mounted in the core (11) by vibration isolating elements (14).
