C-48 



TREC 

 (Tethered Remote Camera) 



Operating Depth : 1,200 ft (366111) 



Dimensions. (LxWxH) : h'y in. x 35 in. x 38 in. (llUcm x 89cm x 9Tcm) 



Weight (dry) : 350 lbs ( 159kg) 



Speed : 



(Max. Operating Current) 1.5 to 2 knots 

 Structure : Rectangular shape composed of open alumin\am (606I-T6) 

 framework which encloses and supports all components. 

 Buoyancy : A syntactic foam package (density 2k Ibs/cu ft) is fixed 

 to the top of the framework and provides neutral buoyancy in sea 

 water. A variable ballast trim sytem is included which operates off 

 compressed air. 



Power Requirements : A diesel generator provides 8 KW, 120 V, 60 Hz, 

 single phase power through an umbilical cable. The umbilical is 

 1,500 ft (i+5Tm) and comprised of 3 Wo. 8's, one (l) shielded twisted 

 pairs and (3) three RG 58' s. 



Propulsion : Four thrusters , all are driven by 1.5 hp universal motors 

 and all are reversible. Two are stern-mounted and provide forward/ 

 reverse thrust, one is mounted amidships to provide lateral movement 

 and one is also mounted amidships to provide vertical thrust. 

 Instrumentation : CCTV (Panasonic low light level), echo-sounder, two 

 lights (variable intensity control), manipulator (optional) with 

 three degrees of freedom, 6 in. (l5-2cm) claw opening. 

 Navigation : Visual sighting, magnetic compass, depth gage. 

 Shipboard Components : Control/display console (control: propulsion, 

 light intensity, camera focus, manipulator functions, TV and video 

 recorder controls; display: CCTV, depth, altitude), cable reel, 

 launch/retrieval device. 



Support Ship Requirements : Can operate from a variety of support 

 ships or barges with a minimum deck area of 30 x 20 ft (9x6 m) 

 Operation/Maintenance Crew : Two 

 Total Shipping Weight : 120 cu ft (3.H cu m) 

 Total Shipping Volume : 1,000 lbs (l+5'+kg) 



Status : Six \inits are operational. Three more \mits will be built in 1979- 

 Builder : International Submarine Engineering Ltd.
