By improving the Self-sheathing Hydraulic Sampling Bottom Device (S.H.S.B.D), GeoPolaris S.r.l. created an innovative underwater corer: the S.H.S.B.D-A. This device, which is able to reduce sample contamination and disturbance to a minimum, was designed to sample non-consolidated sediments. Its remarkable versatility and relative lightness combined with a high penetration power allow using S.H.S.B.D-A in several work environments, from offshore areas, to sea coasts, port, river and lake areas. The availability of four different penetration modes (gravity, vibration, percussion and hydraulic thrust) and the dedicated variable-frequency vibration system allows optimizing the effectiveness of the device depending on the type of sediment to be sampled. Moreover, the modular structure allow to adapt easily the length of barrel (up to 10 meters) to the specifications of sampling. Thanks to its innovative self-extraction system, a compact design and its relative lightness, S.H.S.B.D-A can be easily used on small-sized, shallow-draught vessels equipped with lifting devices (crane or A-frame), with a vertical lifting power of 2 ton, whereas traditional corers need a minimum lifting power of about 8 to 10 tons.
