A new device, called Stingray, has been designed and developed by McClelland Engineers of Harrow, Middlesex, to measure in situ soil properties. The device, a cone penetrometer system, which has been developed and operated in the North Sea is claimed to provide data coverage beyond the limits of previously available equipment. It provides in situ data at any required depth and thus has the versatility needed for use in foundation design for major offshore structures, in improved analysis and construction planning for high capacity piles and in the investigation of liquefaction potential under seismic or wave loading. Stingray utilizes an electric friction-sleeve cone and an electronic readout system to segregate point resistance and sleeve friction. The hydraulic jacking system rests on the sea-floor and transfers load to the cone road through the drill pipe. The system thus provides for testing through hard soil strata. It is able to continue tests to considerable depths even below obstacles, thereby giving it the ability to test a weak layer underlying a strong stratum. /TRRL/
