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.

SubCtech supports Shell XPRICE

 A $7 million global competition challenging teams to push the boundaries of ocean technologies by creating solutions that advance the autonomy, scale, speed, depths and resolution of ocean exploration. The success of this prize will allow us to fully explore and map the ocean floor, and uncover our planets greatest wonder and resource for the benefit of humanity.

Students in the Department of Ocean Engineering at Texas A&M University were recently announced as a semi-finalist team in the Shell Ocean Discovery XPRIZE competition. The multi-national team, comprised of students and professors, is now one step closer in their pursuit of winning the global competition to advance ocean technologies for rapid, unmanned, and high-resolution ocean exploration and discovery.

Dylan Blakeslee, team leader and senior ocean engineering student, is confident in the work that has been completed thus far and optimistic about the future successes in store for them. “We have a lot of work to be done between now and September, but we have an amazing team and support from leading companies in the industry, as well as the Texas A&M ocean engineering department,” Blakeslee said.
