Nautile, a Franch manned submersible
The Nautile is a manned submarine designed for observing and operating at depths reaching 6,000 meters, belongs and operated by IFERMER-Institut Francais de Recherche pour l`exploitation de la Mer (French Research Institute for Exploitation of the Sea). The Nautile is capable of exploring 97% of the world`s ocean floors, commissioned in 1984 and normally supported by the research vessels Nadir or l`Atalante.
The Nautile system provides the following functional features:
Direct viewing, thanks to three portholes affording a wide range of vision, along with six flood lights, object detection on panoramic sonar, manipulation and sampling using two retractable arms and an isothermal basket.
Technical specifications, Nautile:
Since the Nautile is quite lightweight for the performances it supplies, it can be deployed from a support ship of relatively light tonnage and has excellent maneuverability, it includes a small, telecontrolled robot called Robin that can inspect and image areas inaccessible to the submersible itself.
