<p>An anti-pirates apparatus arranged on a ship (100) comprises at least one detection device (10), in particular an optical device comprising at least one thermal video camera that is adapted to detect suspicious watercrafts, unidentified, while approaching the ship (100). On the basis of the detection, the device (10) generates, through a control unit (20), an alarm signal that indicates, after a computing step, an approaching direction of the watercrafts towards the ship (100). The anti-pirates apparatus comprises, furthermore, a launch device (30) that, in the presence of the alarm signal, launches a floating blocking material (50) contained in a projectile (40) as a skein made of strings or ribbons that unwinds during the launch, in order to provide a barrier (51) that extends according to a predetermined length and angular amplitude. In particular, the barrier (51) blocks approaching of unidentified watercrafts (150). In an advantageous way, the skein (50) is made of biodegradable polymeric material that is invisible in water and does not cause a pollution of sea water since after a predetermined period it dissolves naturally.</p> |
