Connecting Science and Society

As part of the decadal conference series, OceanObs’19 will galvanize the ocean observing community ranging from scientists to end users. OceanObs’19 seeks to improve response to scientific and societal needs of a fit-for-purpose integrated ocean observing system, for better understanding the environment of the Earth, monitoring climate, and informing adaptation strategies as well as the sustainable use of ocean resources. OceanObs’19 will continue to develop strategies for a sustained, multidisciplinary and integrated ocean observing system, and better connect user communities and observers.

Greta sails with Malizia, OceanPack RACE on board

Team Malizia, skippered by Pierre Casiraghi and Boris Herrmann have the great honour and pleasure to sail Greta Thunberg from the UK to New York for the UN Climate Action Summit on Malizia II, kicking off a climate tour through the Americas over the next few months.
The Malizia team also developed the Malizia Ocean Challenge, a project to support ocean climate education and the monitoring of ocean CO2 using the OceanPack RACE® system build by SubCtech. This project is affiliated with the Prince Albert II of Monaco Foundation, a charitable organisation that supports work on environmental and climate change issues.

Li-ion battery for a fuel cell UUV

SubCtech has developed and built the Li-Ion battery for an innovative long range Unmanned Underwater Vehicle (UUV). The UUV is being developed by Cellula Robotics Ltd. under the Canadian All Domain Situational Awareness (ADSA) Science & Technology (S & T) Program developed and built. Known as “Solus-LR”, the UUV will have a target range of 2000 km and is designed to stay submerged for multi-month missions. The Li-Ion battery system works with the fuel cell system, taking power peaks and ensuring optimum power system operating parameters.

SubCtech and Kuchenbecker Feinmechanik merge

After many years of successful cooperation, the precision manufacturing company „Kuchenbecker Feinmechanik“ and SubCtech are merging. The production with modern CNC machines takes place from 1 March 2019 in Kiel. This optimizes our production processes and shortens delivery times for our customers. We offer all types of production especially for prototypes and small batches. The focus is on titanium machining for high-precision underwater housings, but also steels, aluminum or plastics for various applications are processed.


SubCtech continues to grow and move into new buildings!

We are proud to have expanded our market position for Li-Ion Batteries and OceanPack Ship Monitoring Systems.
On October 1, 2018, we will start production in another building. We quadruple our space; this optimizes series production and R&D. Our customers benefit from a fast delivery time and lower costs.

Our contact details do not change, but you will find us now in Wellseedamm 1-3.


SubCtech manufactures high-power and high-energy subsea batteries

Last delivered to the USA: 6000m 180V 10kW subsea battery

Our modular and scalable PowerPacks™ now allow voltages up to 600V and energies currently. up to 30kW. The high sophisitcated Battery Management System (BMS) allows to charge under water, e.g. as a subsea UPS or for AUV docking station. The Li-Ion batteries are reliable (subsea up to 30 years), safe and extremely efficient.  Tests are offered according to API17f, ISO 13628-6 or MIL-STD.
