The vessel was commissioned and built in 1975 by Ateliers et Chantiers de la Manche in Dieppe, Seine-Maritime. In 1985, the ship was equipped with the new System Acoustique Remorquè (SAR) sonar device. In early summer, the vessel undertook a 10-day sonar mission in an attempt to find the wreckage of RMS Titanic. Aboard Le Suroît on this mission was Robert Ballard. Le Suroît was able to rule out large sections of a pre-determined 150-square-mile (390 km2) search area – between 26 July and 6 August, 80% of the area had been searched. It later transpired that on one of its first passes, Le Suroît had come within only 3,300 feet (1,000 m) of Titanic. The mission ended on 6 August, after which RV Knorr travelled from the Azores to concentrate on more specific areas using different strategies.
Facilities and equipment
The vessel is equipped with a range of devices. The computers run IFREMER's CARAIBES mapping software. The coring cable is 8 kilometres (5.0 mi) long and is made of Kevlar. It has a safe working load (SWL) of 8 tons. The ship also has a 6-kilometre (3.7 mi) steel winch, with an SWL of 2.1 tons. The average cruising speed, and the speed at which surveying is undertaken, is approximately 10 knots (19 km/h; 12 mph).
