TOTAL POWER: 66 kWh 



SPEED (KNOTS): CRUISE 1/8 hr 



MAX 2/4 hr 



CREW: PILOTS 1 



OBSERVERS 1 



PAYLOAD: 800 lb (Incl. crew) 



PRESSURE HULL: Spherical shape (two hemispheres), of Algoma-44 steel, 0.75 in. thick and 6.5-ft OD. 



BALLAST/BUOYANCY: Thirty gal of oil are carried in a hard aft sphere which can be electricaMy or manually pumped into flexible bladders at 



ambient pressure. Pumping oil into the bladders increases buoyancy at a rate of 64 lb for each ft^ of water displaced. A total of 300 lb of positive 



buoyancy may be obtained with this sytem. On the surface high pressure air can blow clear a circular tank surrounding the upper half of the pressure 



hull and add a total of 2,000 lb of positive buoyancy to increase freeboarc. 



PROPULSION/CONTROL: Two 19-in. propellers mounted amidships on each side the vehicle provide forward or aft movement in the horizontal. 



The propellers are driven by two oil-filled, 5-hp, DC motors which can control screw rotation from to 1 ,200 rpm in either direction. 



TRIM: Up/down bow angles of + 1 5 can be attained by moving the lower battery pod fore or aft by a hydraulic arm. 



POWER SOURCE: Lead-acid battery pack (60 cells) in an oil-filled, pressure-compensated aluminum box rated at 500 amp-hr. 



LIFE SUPPORT: O2 supply is carried internally in a SO-ft^ tank and is manually bled into the hull. COt is removed by LiOH. 



VIEWING: Three viewports looking forward and slightly downward of the horizontal. The two large ports are 6 in. thick, 6-in. ID, 13-in. OD 



providing approximately 48 of viewing each. A smaller viewport is located slightly above and between the two large ports for photography. 



OPERATING/SCIENTIFIC EQUIPMENT: UQC (8-kHz), echo sounder, directional gyrocompass, TV, obstacle avoidance sonar, VHP radio, seawater 



temperature indicator, depth gage. 



MANIPULATORS: One arm, six degrees of freedom, of 82-in, total reach and 150-lb lift. A second clamping arm is available which has three degrees 



of freedom, a jaw opening up to 21 in. and can rotate 360° at the writst. Jaw clamp is capable of lifting or pulling 400 lb. 



SAFETY FEATURES: O2 rebreathers (two ea.). Mechanically jettisonable, 400-lb weight. Surface buoyancy system can be employed in an 



emergency while submerged. Mechanical arms jettisonable. 



SURFACE/SHORE SUPPO:lT: VICKERS VOYAGER & VICKERS VENTURER. 



OWNER: Vickers Oceanics, Barrow-in-Furness, England. 



BUILDER; International Hydrodynamics Ltd., Vancouver, B.C. 



REMARKS: Operational. The basic details, e.g., length, beam, height, etc., are taken from a recent brochure from the current owner; the remaining 



data was obtained primarily from the builder and may be incorrect as the vehicle now stands.
