Victor, dedicated to scientific ocean research, is a deepwater, remote-controlled system. It is instrumented and modular and can perform high quality optical imaging and can carry and operate various equipment and scientific tools.
The lower part of the vehicle is composed of an instrumented scientific module which can be changed according to the type of assignment. It contains most of the instrumentation as well as the sampling basket. This modular system can also be enhanced and used as a technological platform for new equipment.

On-board system overview
The VICTOR 6000 can be taken aboard the 2 French research vessels L'Atalante and La Thalassa or on ships of opportunity.
The VICTOR 6000 gear includes:
- A direct-winding hydraulic winch, the 8,500 m 20 mm umbilical, weighing in all: 30 tonnes(1)
- The vehicle 3.1 x 1.8 x 2.1 m, weight 4 tonnes and 600 kg for the module (2)
- The hard ballast 1.5 x 0.8 x 0.5 m, weight 1.2 tonne (3)
- The tether measuring from 100 to 300 m 35 mm (4)
- 5 20-ft containers (5):
- vehicle power
- winch's hydraulic unit
- control room
The 110-tonne set of gear can be transported in 20-ft containers. Power requirements:
- 50 kVA - 380 V - stabilized 50 Hz for the vehicle
- 2 x 160 kVA - 380 v -50 Hz for the winch
- 60 kW - 220 V et 380 V for the other equipment
- Compressed air and water
Basic sampling and scientific module
Victor 6000 has a basic sampling module composed of the following elements:
- 3 temperature probes which can be manipulated
- 8-sample fauna suction device
- Water sampling pump (19 x 200 ml)
- Titanium sampling tubes (4 x 740 ml)
- Sediment corers (d=53 mm, l=400 mm)
- 6 drifter markers
- Mobile 0.6 m basket
- Grab sampler
- Sample boxes
Scientific module interface specifications:
- length: 2.5 m
- beam: 1.85 m
- height: 0.7 m
- weight in water 100 tp 150 daN
- 24 V DC/200W
- 240 V DC/5 kW
- hydraulics: 3 kW à P=210 bars maxi
- 2 RS 422 links at 38400 bauds
- 1 RS 232 link at 9600 bauds
- 1 video channel (CCIR standard)
POSIDONIA makes it possible to position several mobiles and targets at depths down to 6,000 m. The real-time trajectory-plotting and navigation aid are provided by the VEMO+ software.
Data centralization system
The data (vehicle, module, navigation, ship) are centralized on a server and can be disseminated on CD-ROMs. They are compatible with the ADELIE set of software for displaying, handling and enhancing data, images and videos recorded from Ifremer submersibles.
The control room which is built into a 20-ft container, provides piloting of the vehicle and control for the entire system.
It has three operator stations:
- The pilot
- The operational coordinator
- The researcher
The Victor is operated and maintained by GENAVIR; Ifremer carries out technical monitoring and developments.
The main industrial partners involved in developing the submersible are:
- CRP for the floater
- CYBERNETIX for the MAESTRO computer-aided, manipulator arm
- DEFREANE for vehicle's power
- DE REGT for the tether
- HYTEC for the digital still camera
- GENISEA for electronic set-up in pressure vessels
- JM MOTEURS for propulsion
- SCHLUMBERGERfor the electric and optic umbilical
