RT 6000M Deepwater ROV

The RT 6000M was designed for geologic exploration in the World's Oceans (to a depth of 6000 m) to study sulphides, cobalt-bearing crusts, metal-bearing oozes etc. that are difficult to explore with tow hardware systems. It is also suitable for inspections, the taking of measurements and other deep-water studies.

Application	Auxiliary
Geological exploration Search and inspection of sunken objects Underwater inspection / intervention of pipelines, deep-water cables, underwater geotechnical constructions Environmental studies	Sonar Differential magnetometer Manipulator Short / ultra short-baseline underwater acoustic navigation systems

Towed TV-Systems

Towed Underwater Survey System «Neptune-D»

The «Neptune-D» is an open steel frame with hard boxes containing a battery, underwater electronics, and photo/video cameras.

Underwater variable day lights, an underwater strobe light and an echo-sounder antenna are mounted under the steel frame.

Power supply — 4 batteries (12V, 95AH each) provides 20-hours of continuous operation in black-and-white mode.

2 halogen lamps (75Vt each) are used to provide underwater video survey. A 500 Joules flashlight is used for photography.

An echo sounder (operating frequency 165 kHz) is provided for control over altitude is incorporated into the «Neptune-D» system.

The echo sounder also controls automatic photo survey at a designed altitude. Additional photos can be taken manually in locations specified by the operator.

The shipboard control console that is provided for selection of operating modes and for reception and matching video signals is connected to an IBM PC to record frame numbers, time and altitude for providing image zooming if necessary.
