Lübeck (Germany), 23 June 2026 – Gabler Group AG (ISIN: DE000A421RZ9 / Ticker: XK4, the “Company” or “Gabler”) an established developer and manufacturer of mission-critical subsea technologies in the business areas of Submarine Systems, Subsea Communications & Data, and Subsea Power, has secured a contract valued at approximately EUR 6 million through its subsidiary Develogic.
The contract underscores Gabler’s strong market position in safety-critical communication and data systems for maritime applications, further strengthens the Subsea Communication & Data business area, and reflects the continued strong demand across the markets served by the Company. Project implementation will commence immediately following contract award, with initial revenues expected to be recognized in fiscal year 2026.
The contract comprises the delivery of an innovative solution for secure underwater communications as well as the collection, transmission, and processing of data in maritime operating environments. The objective is to expand the capabilities of existing platforms through the flexible integration of external systems and to unlock new applications for maritime and subsea operations.
David Schirm, CEO of Gabler Group AG, commented: “This contract highlights the growing importance of advanced communication and data systems for modern maritime and subsea operations. At the same time, it confirms our technological expertise in safety-critical applications. The renewed business from an existing customer strengthens our position in the Subsea Communication & Data business area and demonstrates the differentiation of our solutions.”
To address these requirements, Gabler’s subsidiary Develogic develops technologies for secure communications, connectivity, and data transmission for maritime and subsea applications. For example, additional sensors or external systems can be integrated into maritime operations, while the resulting data can be transmitted and processed reliably. The technology’s high resilience, modular architecture, and adaptability were key factors in the customer’s decision to award the contract to develogic once again.
The contract reflects the continued positive development of the markets addressed by Gabler Group. As of 31 March 2026, the Company reported an order backlog of approximately EUR 376.8 million and operates in markets driven by long-term investment programs in maritime security, critical infrastructure, and defense technologies.

Develogic has confirmed the successful deployment of two Modular Seafloor Landers (MSLs) at depths exceeding five kilometres in the central Pacific Ocean, the deepest operational deployments in the company’s history, alongside delivery of seven Sonartransponders across two North Sea offshore wind farms, marking a significant expansion of its offshore energy monitoring portfolio.
The Pacific deployments confirm that free-fall installation remains viable beyond five kilometres of water depth, a milestone that extends the operational envelope of Develogic’s MSL platform and opens access to a class of seabed environments previously beyond reach for standard instrumentation approaches. The landers were deployed without ROV assistance, free falling to the seabed and touching down the correct way up. Both units are now operational, collecting data and transmitting results via acoustic telemetry to the surface.
The offshore wind programme involved the delivery and installation of seven wireless Sonar Transponders at two producing wind farms in the North Sea. The Develogic Sonartransponder is an acoustic collision warning system that provides underwater vehicles – including survey ROVs, inspection AUVs, and naval submarines with accurate positional data on fixed subsea infrastructure. It responds to predefined acoustic interrogation signals with standardised navigation warnings, enabling approaching vehicles to localise wind farm foundations, inter-array cables, and monopile structures in conditions of limited visibility.
This deployment introduced several technical advances over previous iterations. Electromagnetic (EM) communication across the water-to-air boundary – linking submerged transponders directly to topside infrastructure without acoustic relay – was implemented operationally for the first time in this configuration. Mounting systems were engineered to withstand storm loading equivalent to a 50-year return period event, meeting the structural requirements of permanent installation on operational offshore infrastructure. The project also included a refined installation methodology developed to reduce vessel time and diver exposure during deployment.
Both programmes demonstrate the breadth of environments in which Develogic systems now operate – from the abyssal depths of the Pacific Ocean to the shallow waters of the North Sea. Develogic’s modular engineering philosophy builds subsea systems from configurable, pressure-rated building blocks rather than fixed, single-purpose designs. The same core technologies; acoustic communications, pressure housing architecture and intelligent data management – scale seamlessly from scientific landers operating at depths of 5,000 metres to compact transponder systems supporting offshore wind farms in just 30 metres of water.
The offshore wind sector is entering a phase of rapid expansion in both capacity and geographic scope, with new farms being commissioned at greater distances from shore and in deeper water. The requirement for reliable subsea navigation infrastructure – capable of guiding the growing fleet of AUVs and ROVs operating in and around these sites – is a structural consequence of that expansion. Develogic’s Sonar Transponder programme, now with multiple operational installations across the North Sea, is designed to scale with it.
Further programme milestones, including environmental monitoring redeployments at floating offshore wind facilities in Norway and continued deep-sea operations in the Pacific, are ongoing.
