Experimental and analytical studies, conducted to evaluate continental shelf depth performance of a spherical acrylic plastic hull, have led to the design and construction of NEMO Naval Experimental Manned Observatory. NEMO consists of an acrylic plastic pressure hull with a 61-inch inside diameter and a 66-inch outside diameter, plus life support and operational subsystems. The life support system provides 8 hours of life support, plus an additional 24 hours emergency backup for two men. Operational subsystems include a main lead acid battery power supply, electrical distribution and control circuitry, a hydraulic system to operate a self-contained winchanchor system, and two side-mounted thrusters for rotation and short horizontal excursions. An air ballast system is included for controlling buoyancy. NEMO is certified by the Navy for operation at depths to 600 feet. Author-PL
