Objective The objectives of this contract are first to develop a sediment core driller for decametric penetractions and second to add a rock core driller to the bathyscaph, (the only manned european device capable of operating in very great depths). The need has also appeared to improve the navigating rotation and data collection capabilities of the cyana.Reconnaissance of the geological characteristics and mechanical properties of sea beds by sampling cores is of interest to all sectors of the oil industry involved in harnessing deep offshore oil.Core drillerA compact core driller has been built and successfully subjected to sea trials. The results have enabled the construction of an industrial size (20 metres long) prototype to be started.CyanaThe cyana bathyscaph was equipped with a prototype rock core driller to extract cores 100 mm in lengh and 25 mm in diameter. Its implementation using a remote-handling arm was successfully tested at sea. A series of additional tests is also planned. Substantial improvements have been made to the cyana with respect to its navigating location ability, the identification measurements now being made from the vessel itself, and not from the support ship. The capacity for acquiring data on the environment has also been increased without any corresponding increase in the volume and weight of the equipment.
