OSSA POWERLITE^{®
Diesel-Electric Marine Propulsion Systems and Accessories}
 

Project Description:

Nautilus is Exomos' version of the submarine in Jules Verne's 20,000 leagues and is intended to be used by tourist resorts to give visitors a unique view of the local marine environment.  It seats seven, with the option to add 2 jump seats.  The anticipated final weight in water is eight tons, 15.5 meters long, 2.5 meters in diameter. Nautilus is Powered by our OSSA Powerlite a 500vdc version of our OSSA Powerlite 35hp motor.  The motor turns a 26" x 13" pitch,  5-bladed propeller.  Power is provided by a state-of-the-art 512v lithium-ion battery pack which is recharged at dockside.

Like the Proteus, the Nautilus is designed for operation at the surface and to shallow depths (25 meters maximum).  The air supply is self-contained giving a typical submerged time of around three hours, depending on air consumption. Nautilus has four cameras mounted, one giving the pilot a heads up view of his blocked vision area, a tail mounted camera which allows the passengers to see the sub as it glides thru the water, a nose-mounted down looking camera so the pilot can observe the bottom for obstacle avoidance.  The fourth camera will be mounted in a towed, surface buoy.  This buoy, which will be a miniature, (1 meter long) replica of Nautilus, will have a VHF antenna, an active GPS antenna and the camera.  Both the sub and buoy are painted like a leopard Moray eel.
