Integration benefits
SubCtech was acquired by Gabler Maschinenbau in August 2025
The deal was agreed because both companies saw overlap in the field of maritime technology, and the move aimed to leverage shared sales channels, merge technology and respond to market changes including the energy transition and resulting expansion in offshore wind, solar, and wave technology leading to an increased need for ocean data and environmental monitoring.
Growth in new areas
SubCtech also expects the move will lead to growth in the following areas: offshore traditional energy, oil and gas; renewable energy and CCS; subsea security and defence; ocean monitoring and climate science; and autonomous underwater and surface systems.
The merged company will also be better able to respond to defence demands as a result of ongoing geopolitical tensions.
Fully integrated subsea systems
The newly enlarged company is currently preparing to develop fully integrated subsea ecosystems, which will entail scaling production and global delivery capabilities, investing in data-driven and autonomous solutions, as well as expanding international market access.
A focus on Management continuity
Since joining Gabler and becoming part of the Gabler Group, SubCtech has maintained continuity in its management, with founder Stefan Marx remaining in place as the managing director. This has helped ensure strategic and operational stability while also aligning with group-level governance structures.
Sören Johannsen, chief operating officer and marketing at SubCtech, said, “Integration into the group enhances alignment in governance, reporting, and strategic decision-making in accordance with Gabler’s established integration model, while leveraging common sales and marketing approaches to drive further growth and market presence.”
No major structural changes so far
In addition to maintaining continuity in its management, no major structural downsizing or relocation has been indicated so far. Both companies are continuing to operate at their existing sites, with Gabler in Lübeck and SubCtech in Kiel.
However, Johannsen explained that, from SubCtech’s perspective, teams are becoming increasingly functionally integrated, with strong growth driven by projects, expanded market reach, and a rapidly growing market, with departments becoming generally more interconnected across the group.
Why the deal makes sense
The alliance between the two groups is complementary: SubCtech provides subsea power systems and ocean monitoring systems, whereas Gabler’s expertise lies in submarine systems and mechanical platforms, as well as subsea communications, data, and analytics.
Johannsen added that the combined value proposition of the pair will be end-to-end subsea solutions – power, sensing, data, and platform integration, as well as the ability to serve offshore energy, defence, and ocean science markets holistically. This directly addresses the growing demand for integrated subsea systems rather than standalone components.
Operational benefits
The merged group will see economies of scale since SubCtech provides access to Gabler’s global sales infrastructure; shared supply chains and procurement efficiencies; cross-selling opportunities and shared research and development resources, thereby reducing duplication and accelerating innovation. These benefits help the group to scale faster than if they were standalone entities.
A strategic shift in focus
Since the acquisition, SubCtech’s focus has largely remained the same, with subsea power and ocean monitoring, but Johannsen explained there has been a clear strategic shift in emphasis, reflecting alignment with the Gabler Group’s broader subsea systems strategy. This includes providing an end to end system, from component provider to integrated solution provider; stronger positioning in defence and security-related subsea applications, according to current market dynamics; and an increased role in large-scale multi-system projects.
Future developments
The deal was designed to help pave the way for several future developments that will include joint product development, expansion of global sales channels via Gabler’s network, an increase in production and innovation capacity, as well as cross-company technology integration across SubCtech, Develogic, and north.io. Johannsen said: “These initiatives are explicitly part of the Gabler’s growth strategy, including increased research and development as well as investment in sales.”
Looking ahead
As integration progresses, the focus will centre on delivering the developments outlined as part of the deal, including joint product development, expanded global sales channels, and scaling production and innovation capacity.
With technology integration across SubCtech, Develogic and north.io, the combined company is moving towards fully integrated subsea ecosystems that bring together power, sensing, data and platform solutions.
