<p>A seabed measurement or sampling system has a frame 1 which may be placed on the seabed. The frame contains rods 12 and a facility to assemble a string 13 of rods. A probe 11 is mounted on the string to be pushed into the seabed. Assembly of the string occurs while the rod string is being pushed or driven into the seabed or during pauses between pushing. The sampling system may be a seabed penetrometer. There may be an assembly and disassembly unit 22, and a rod storage system 16, such as a magazine, rack or carousel. There may be a rod string break detector (60, figure 4) such as a camera, sensor or time domain reflectometer. The detector may include an arm (62, figure 4) urged to contact the rod string, and a wheel (68, figure 4) which may be used to measure depth of penetration.</p> |
