Data you can trust. Performance you can prove.
Shipping doesn’t run on promises. It runs on decisions made in real conditions, every day.
At GTT Marine, we combine decades of engineering expertise with advanced maritime intelligence to deliver reliable data, trusted monitoring, and insight operators and shipowners can act on with confidence.
By bringing together onboard systems, safety and performance monitoring, voyage optimisation, and advanced analytics, we turn complexity into clarity, helping crews and onshore teams operate safer, more efficiently, and in full control.
Because real performance starts with reliability you can depend on.

What Worked Yesterday Doesn’t Work at Sea Today
For years, maritime systems were built in silos, each solving a specific need, but rarely designed to work together. As operations have become more complex, this fragmented approach is reaching its limits. Data is captured, but not always trusted. Insights exist, but not always when decisions are made. And the gap between onboard reality and shoreside understanding continues to slow teams down. What once worked is no longer enough to support the demands of modern shipping.
Delivering the GTT Marine Insights Platform to enhance efficiency and safety across the maritime industry
A Platform Purpose-Built for Collaboration and Business Scaling
The ever-changing needs of the global maritime fleet highlight the importance of flexibility and scalability in any technology platform.
With our agnostic platform, we enable the maritime sector to transition from noon reports and standard-based navigation to vessel-specific high-frequency data tailored to real-time scenarios.
A New Standard for How Shipping Operates
As maritime operations evolve, incremental improvements are no longer enough. What’s needed is a shift in how data, systems, and decisions come together.
Operators and shipowners don’t need more tools to manage. They need systems that work together. They need a way to move from fragmented inputs to a clear, shared understanding of operations.
Because in today’s environment, performance, safety, and compliance depend on having the right information, in the right context, at the right time.
Built as an Integrated Backbone for Modern Shipping
GTT Marine brings together onboard systems, trusted monitoring, and advanced maritime intelligence into one connected foundation. From safety and compliance to performance and data, every layer is designed to work together, so operators and shipowners don’t have to manage complexity across disconnected tools.
By combining reliable data capture, real-time insight, and proven performance expertise, we provide a consistent and actionable view of operations. Enabling crews and onshore teams to make better decisions, every day, in real conditions.
Our Legacy
GTT Marine is the result of a deliberate shift.
As maritime operations grew more complex, no single solution could address the full picture - data capture, operational insight, and performance optimisation remained fragmented across the industry. GTT Group recognised that solving this required more than incremental innovation. It required bringing together the best capabilities available.
Through the acquisition of Danelec, Ascenz Marorka, and Vessel Performance Solutions, GTT Group assembled three proven leaders, each best-in-class in its field.
Combined, they form GTT Marine in 2026 for a unified approach that connects onboard data, operational decision-making, and performance intelligence into a single, coherent foundation.
With over three decades of experience, Danelec provides the foundation of maritime operations. Its onboard systems capture and monitor critical data, ensuring safety, compliance, and a reliable flow of trusted information. Strengthened by the integration of Kyma and Nautilus Labs, Danelec extends this foundation with advanced monitoring and data-driven optimisation capabilities.
Ascenz Marorka brings together complementary expertise in maritime performance and energy management. Combining Ascenz’s experience in fuel monitoring with Marorka’s long-standing expertise in vessel performance monitoring, it enables crews and onshore teams to make smarter operational decisions, reducing fuel consumption, improving efficiency, and optimising voyages in real-world conditions.
Vessel Performance Solutions is a recognised expert in advanced performance analytics. With over a decade of experience, it combines deep maritime expertise with physics-based modelling to turn operational data into clear, actionable insights. Its solutions enable benchmarking across vessels, support emissions compliance, and help shipowners and operators better understand performance drivers to drive continuous improvement across the fleet.
