The invention relates to a protective device for preventing fluids, either gaseous or liquid, from escaping into a body of water in an unforeseen or uncontrolled manner, e.g. from a fault 14 in the bottom 15 of the body of water or from the defective riser 16 of a wellbore. The protective device has a dome-shaped membrane 12 that is impervious to the fluid. Further, it has individually navigable flotation devices 17 that are attached to the membrane 12 for the purpose of positioning and stabilizing the membrane 12. An outlet hose 102 for extracting the fluid is mounted on the membrane. The outlet hose also has individually navigable flotation devices 17 for positioning and stabilizing the outlet hose.
