Welcome to Oktopus


Oktopus GmbH is your first point of contact for the development of integrated maritime systems in Germany. As a system integrator we offer many years of experience in the development and deployment of equipment for a deployment range of 6,000 m water depth and more.

Since the company was established in 1998 we have been applying our know-how to meet your requirements in our core fields of expertise: mechanical engineering, electronics and mechatronics.

We design complete maritime systems to meet your specific requirements. These include carrier and towing systems, camera and lighting components, and sediment and water sampling equipment in all shapes and sizes.


Systems can be certified by Germanic Lloyd (GL) on request. This means that Oktopus products can also be optimally deployed on vessels with stringent safety requirements.

Come and get a first impression and discover, with our help, the solutions available to meet your specific demands - we are looking forward to the challenge!



New members of the Oktopus Multiple Corer family




Oktopus proudly presents three new members to the Oktopus Multiple Corer series. With models MC 01-03 the focus shifts towards low dimensions as well as low weight. For applications with high space and weight constraints, the new MC 01-03 is a perfect match.

Successful work with the Oktopus pressure tank at the LZH

- innovative plasma observation under laser action



The current edition of "Schiff und Hafen" is titled "Lasertests unter Tiefseebedingungen am LZH". This refers to the use of a pressure tank developed by us to pressurize materials and materials. In this case, they are moved with up to 650 bar under laboratory conditions to the environmental conditions of the deep sea. Subsequently, various tests with laser radiation, which passes through a special window in the interior, carried out. Further information on the innovative and unique pressure tank can be found under the following links:

The German Center for Marine Biodiversity Research (DZMB) at Wilhemshaven/Germany, part of the Senckenberg Research Institute and Natural History Museum ordered the first OKTOPUS GmbH giant multiple corer with 20 core tubes




Since 2016 OKTOPUS GmbH offers its new three hydraulic damped multiple corer versions MC 04-08, MC 08-12 and MC 12-20 with 4 and up to 20 core tubes to be used on small ships working in shallow and coastal water areas as well as on large modern research vessels for deep sea deployments. Compared to the older versions, the advantages of the converted frameworks are primarily the stainless steel Oktopus Modular Frame System (OktoMFS). Do away with welded connections in favor of flexibility, hand-in-hand with effective transportation and space-saving storage even for air transport, as well as additional sensors or a video telemetry system and lights which can easily be attached. Excel is the new entire core tube holder which can quickly be detached from the head including the sample for immediate further treatment in the lab or storage if required. The area required of the 4 leg, 1.1 m high framework is 1.882 m x 1.882 m, the total height of the multiple corer is 1.8 m. Compared to the up to today largest version with 12 core tubes, 20 successfully sampled core tubes means 66 % more samples from one deployment and saving valuable ship time especially during deep-sea research cruises and monitoring tasks.

DNV GL certified sapphire glass down to 1,100 bar

- a view without limits (up to Ø 100 mm)



In the course of the outside pressure test bench project a method for certifying sapphire glasses was developed in collaboration with DNV GL. Oktopus GmbH is now capable of supplying optical viewing ports for cameras, lasers or other optical components for a wide range of purposes, down to full ocean depth (1,100 bar).

As our customer, you are free to choose the dimensions and shape of your window, up to a diameter of 100 mm. It is also possible for you to select a coating to meet your specific demands (e.g. for enhanced transmission) from an extensive range. Installation in plastic, aluminium, stainless steel, duplex or titanium pressurised casings, for example, is possible.

And did you know: Oktopus is unique in this field.




Special-purpose and industrial engineering plant

- External pressure test bench with window



The electrohydraulic external pressure test bench is used in industry for research and development purposes. For preliminary studies, e.g. in the context of future marine mining, it is useful to create a laboratory environment in which experiments with system pressures up to 650 bar can be performed. The tank is highly compact and can therefore be flexibly integrated in the user's laboratory or application environment, including through the mobile control and unit console.

As the customer, you can choose from a large number of options in terms of electrical and LWL feed-though points and select from a wide range of materials for viewing ports.

Of course, this external pressure test bench is DNV GL certified.

And did you know: Oktopus is happy to provide you with DNV GL certified sapphire glass for your application. Ask us about it!




Oktopus Modular Frame System

- The focus on your application



Quickly give your carrier frame a new lease of life with the variable Oktopus OktoMF-System carrier kit. Do away with welded connections and their corrosion problems in favour of flexibility, hand-in-hand with effective transportation and space-saving storage. You redesigning your own specific rack and supplement your existing carrier components as needed without having to retain storage space for expired equipment.

For example, use today as an OFOS (Ocean Floor Observation System) and on the next trip anchored long-term as a lander.

Your technology demands are always at the forefront. Guaranteed cost-efficiency thanks to multiple uses and durability of the highest quality and precision.

Video-guided Hydraulic Deep-Sea Grab in operation

new one was ordered by
Korea Institute of Ocean Science and Technology



The third video-guided hydraulic deep-sea grab has been in production for the Korean Institute of Ocean Science and Technology since March 2016. The grad will be equipped with a redesigned hydraulics concept, fibre-optics telemetry and real-time camera system and be deployable at water depths up to 6,000 m. To mark the occasion there will be a video of the deployment on the vessel FS Sonne (SO241) in 2015, with the kind permission and provision of Helmholtz Centre for Ocean Research Kiel (Geomar).




New Multiple Corer ("Oktopus-Prime") on RV Sonne SO-248 at 4,200 m depth




The Multicorer, shipped in February 2016, successfully delivered the first samples to the deck of FS Sonne. With friendly support, here the link to the Carl von Ossietzky University of Oldenburg blog:





New Multiple Corer available

up to 20 tube holders - Full Ocean Depth



Multiple Corer "MC 6-8"-Series: lightweight for smaller vessels


Multiple Corer "MC 8-12"-Series: heavier version for deep sea


Multiple Corer "MC 16-20"-Series: heaviest version with up to 20 tube holders


Our Multicorer family is growing. Now that the "MC 4-8"-Series (lightweight version for small vessels) has been profiting from the new OktoMFS profile system for a whole year, the "MC 8-12"-Series follows (heavy-duty version for deep-sea deployment). The new OktoMFS profile system allows the simple replacement of damaged components and the attachment of cameras, floodlights or sensors, for example.
