Partners to Bring Wireless Subsea Robotics to Scandinavia

Hydromea has entered into a commercial partnership with SepcoTech A/S to represent its EXRAY subsea inspection system across Scandinavia, initially focusing on naval, defense, maritime, and offshore applications.

The EXRAY system is designed to inspect submerged and enclosed areas that are difficult, costly, or unsafe to access with divers or conventional tethered remotely operated vehicles (ROVs), such as ballast tanks, internal structures, and other flooded confined spaces aboard naval vessels and maritime assets.

To navigate these complex environments, the platform combines two coordinated vehicles: a tethered mothership ROV that operates in open or turbid water for traditional missions, and a compact wireless flyout vehicle teleoperated through a high-speed communications relay. Deployed directly from the mothership, the flyout vehicle can enter confined spaces without a tether that could snag or become entangled, while transmitting real-time HD video to the same operator to maintain inspection continuity without sending personnel into the asset or investing in additional ROVs.

“Partnering with SepcoTech gives Hydromea a strong, highly relevant route to market in Scandinavia,” said Alexander Bahr, Co-founder and COO of Hydromea. “Their experience serving defense and maritime customers makes them an ideal partner for bringing EXRAY™’s unique confined-space inspection capability to naval operators and other critical-asset owners.”

For defense applications, EXRAY can be configured to meet specific naval data-handling and security requirements. These options include operation without onboard recording, controlled data routing, and customized security architectures, supporting defense operators seeking to modernize inspection workflows while retaining full control over sensitive operational data.

“Many essential inspections must be performed in places where deploying a diver—or even a conventional tethered ROV — is impractical,” said Peter Krogh, CEO of SepcoTech. “EXRAY™ addresses precisely this challenge. Its mothership-and-wireless-flyout architecture allows operators to inspect enclosed flooded spaces safely and efficiently, while its configurable data-handling approach makes it especially relevant for naval customers.”

Ultimately, the regional deployment of this technology aims to assist asset owners in reducing personnel exposure, avoiding unnecessary dry-docking, and improving the speed and quality of subsea inspection data collection.
