Oktopus GmbH is one of the first contact points for the development of integrated marine systems in Germany. Expert in design, construction and operation of devices in an operational depth up to 6000 m and more. Carrier systems, towed systems, cameras, lights, various sediment and water samplers in any size and shape.
Video-guided hydraulic grab Deep-Sea Grab can be employed wherever the Box Corer cannot operate. Due to its high unladen weight (2 t) and great force at the edges (max. 45 kN) the Video-Guided Hydraulic Grab penetrates even coarse sands and stone. The grab can hold 0.6 ms3.
Equipped with Oktopus’s telemetry and hydraulic OktoHPU the device can be operated with a coaxial cable as well as with a coax/fibre optic hybrid cable. Using the optical fibre cable a color video showing the seafloor and the sampling process can be obtained. Optional sensors enable you to simultaneously overview certain data.
It is a hydraulic unit with a rated power of up to 2 kW which can be supplied either by a battery or from a ship. It was designed for powering the Video-Guided Hydraulic Grab and features a synchronization system simultaneously controlling two hydraulic cylinders. The drive and control components are integrated into the oil tank, while the electrical actuation unit has a separate pressure housing. The volumetric flow rate is continuously adjustable.
This unit is available with several levels of performance which makes it suitable for a wide range of applications: drilling units, breakers, hydraulic saws. Each hydraulic tool (open circuit) is thus capable of being employed underwater.
