Gravity Corer
Gravity corers are used to remove sediment cores from the seabed. The penetration depth depends on the type of corer, its weight, and the nature of the sediment. Depending on the corer type various deployment requirements in terms of the ship, the winch, and the slider or A-frame must to be fulfilled. We can offer corers in different weight classes and materials for core diameters between 60 mm and 125 mm and variable tube lengths.
 
We supply extensive accessories and wearing parts for your equipment. We also hold handling equipment and sample processing tools (e.g. extruders, core slicers, tube cutters, core catchers). We will also be happy to supply you with a non-standard gravity corer to suit your application.

Multiple Corer "MC 01-03"-Series
When undisturbed samples of the upper boundary layers between sea floor and the water column are a primary concern, the Multicorer celebrates 30 years of successful operations around the world. The traditional design is tried-and-tested and is now replaced by a newly developed generation with a more servicing-friendly design, reduced height and made entirely from V4A stainless steel. Thanks to the OktoMF system the equipment can be easily expanded to implement camera systems (with/without telemetry) and a variety of sensor systems.
 
As an Oktopus customer, you can specify the tube diameter, the number of tubes and the tube material for a wide range of samplers. We also offer a core tube optimised for CT scanners.
 
In addition, a wide range of accessories such as extruders, stoppers, replacement tubes, and wearing and spare parts is available.

Video-Guided Hydraulic Grab
The video-guided hydraulic grab (VgHG) is deployed wherever a box corer reaches its limits. Due to its high unladen weight (2 t) and great cutter edge force (45 kN max.), the video-guided hydraulic grab even penetrates coarse sands and stones. The scoops can hold 0.6 m³.
 
Equipped with Oktopus telemetry and the Oktopus hydraulic OktoHPU, it can be operated using both a coaxial cable and a coax/fibre-optic hybrid cable. In fibre-optic cable mode it delivers coloured images of the sea floor and the sampling process. It is also possible to simultaneously transfer data from a variety of optional sensors (e.g. pan & tilt, compass, CTD, depth, sonar). A variety of positioning systems can easily be integrated by the user or at Oktopus.
 
By the way: The VgHG is the first scientific instrument in Germany to be certified by Det Norske Veritas - Germanic Lloyd (DNV GL)!
