Rosenxt :: High-Tech Solutions for Customers Operating Critical Infrastructure in the World’s Harshest Environments

Rosenxt is a forward-thinking, privately owned technology group headquartered in Stans, Switzerland, and founded in 2023 by Hermann Rosen, the visionary behind the original ROSEN Group. With roots in decades of engineering excellence, Rosenxt combines expertise in sensors, autonomous robotics, AI, and advanced materials to develop high-tech solutions for customers operating critical infrastructure in the world’s harshest environments. These include subsea and offshore structures, industrial manufacturing facilities, waterline systems, and the energy upstream sector.

Rosenxt operates with a long-term perspective typical of a family-influenced enterprise, focusing on sustainable value creation, innovation, and addressing future challenges in infrastructure integrity and performance optimization. The company employs several hundred specialists across locations in Germany, Switzerland, the United Kingdom, the Netherlands, Canada, the United States, and Vietnam, positioning itself as a global partner that explores disruptive opportunities while building ventures around critical needs. Its business areas encompass Offshore Engineering Structures, Water Line Integrity, Subsea Structures, Upstream Optimization, Industrial Diagnostic Systems, Advanced Offshore Components, Non-intrusive Flowmeters, Advanced Materials, and critically for robotics users, Maritime Robotics.

Rosenxt’s most prominent robot-based products are its advanced Autonomous Underwater Vehicles (AUVs) developed under the Maritime Robotics division. These uncrewed platforms address the limitations of traditional remotely operated vehicles (ROVs), which are often weather-dependent, expensive, and require dedicated support vessels. Rosenxt AUVs are engineered for fully autonomous, long-duration missions without surface vessel support, capable of operating in any sea state and reaching deep-sea depths.

The vehicles feature in-house design, manufacturing, and integration of cutting-edge sensing technology paired with a sophisticated autonomy stack. They navigate globally while carrying diverse sensor payloads to collect high-resolution data in the water column or above the seabed at constant resolution. Onboard processing enables real-time decision-making without human intervention, making them ideal for time-critical or dynamic missions. Applications include detailed seafloor surveys, inspection of subsea pipelines and power cables, assessment of offshore windmill foundations and other platforms, exploration of shipwrecks, and environmental monitoring. Benefits include rapid deployment, extended range and endurance, reduced operational costs, lower CO2 emissions, and expanded operational windows in harsh conditions where vessel-based solutions are impractical.

In January 2026, Rosenxt acquired K.U.M. Umwelt- und Meerestechnik Kiel GmbH, a leader in subsea data acquisition technology. This integration significantly expands the robotics portfolio with Ocean Bottom Seismometers (OBS), modular data loggers, seabed lander systems, and deep-sea sensor platforms. The combined offering delivers end-to-end ocean monitoring solutions for seismic monitoring, CO₂ storage surveillance, infrastructure security, and scientific research, supported by nearly 30 years of offshore expedition experience across 40 countries.

Rosenxt positions its AUV platforms as versatile, weather-independent tools that deliver reliable subsea asset intelligence. The systems emphasize autonomy, precision navigation, and sensor fusion while integrating with the company’s broader portfolio of integrity and optimization technologies. Beyond hardware, Rosenxt provides tailored engineering support, customization, and deployment expertise, helping clients move from traditional inspection methods to scalable autonomous monitoring in offshore and subsea environments.

Rosenxt continues to invest in R&D to push the boundaries of maritime robotics, combining its historical engineering heritage with agile innovation to create future-ready solutions for the energy transition and critical infrastructure protection.
