Coring system for obtaining pristine sediment cores containing gas hydrates from sea floor

MAC-A (Multi-Autoclave-Corer) and APC-A(Autoclave-Piston-Corer) ANAXIMANDER are designed to be winch-operated on offshore platforms to obtain, gravity driven, seabed samples conserving the in situ conditions.

The MAC is able to secure up to four pristine cores of 80mm in diameter and max.1m in length. Its universal joint and attenuated motion promises undisturbed sampling in particular in uneven environment. The aluminium sample vessels are, certified to sustain operational pressures up to 250 bars and facilitate non-destructive screening (e.g. CT) while light enough to be handled easily. To investigate physical parameters of the samples and to take in situ sub samples (e.g. water or sediment) it can be coupled to the ARS (Autoclave Rod Sub-sampler.

The APCA is certified for 200bar of operational pressure and capable to achieve samples of up to 2.5m length by falling free into the seafloor.
Both gadgets can be interfaced with degassing installations.
