The evaluation of the first year of intensive scientific use of the

French deep sea Remotely Operated Vehicle (ROV) "VICTOR 6000 "is

presented.

VICTOR was used in 2001 during five cruises on continental margins.

ZAIROV 1 & 2, BIOZAIRE 1 & 2 cruises were conducted offshore Western

Africa and CARACOLE cruise along the North East Atlantic margins

(Porcupine and Rockall bank). Cold seep settings (up to 3000 m depth),

coral mounds (400-1000m), oil exploration rigs (1300 m) and Zaire

channel (about 4000m)were explored.

VICTOR was also used during two cruises (IRIS & ATOS) on the

hydrothermal vent areas in the Mid Atlantic Ridge (Menez Gwen 850m,

Lucky Strike 1650 m and Rainbow 2350m).

Finally, VICTOR was used by Alfred Wegener Institute, through a

French-German cooperation in arctic deep sea research, to study high

diversity of species in the deep sea , in high latitude.

Different strategies were tested during those cruises like survey and

exploration or experimental work on small areas. The dives duration

ranged between 8 to 28 hours on the bottom. The high potential of

Victor was confirmed in both strategies with a high ability for

manipulation and the trials of varied instrumentation.

The status and recent evolutions of the VICTOR 6000 are presented

showing the essential role of a dynamic technical support oriented

toward the satisfaction of the scientific objectives and operability.
