Danelec, a leader in maritime safety and digital performance solutions, has been acquired by the GTT Group to respond to accelerating market shifts driven by decarbonisation and digitalisation.
This strategic move creates a global, market-leading digital platform powered by high-frequency, high-quality data. The combined offering is designed to deliver smarter, data-driven solutions that help ship owners enhance safety at sea, optimise vessel performance and improve operational efficiency.
GTT, a company incorporated in France and listed on Euronext Paris, is a French technology and engineering company, and the world leader in the design of cryogenic containment systems for the maritime transportation and storage of LNG. GTT operates in three key sectors: high performance liquefied gas containment systems, smart shipping software & services, and the development of low-carbon technological solutions. This acquisition fully aligns with GTT’s development strategy in the digital field and marks an important milestone for the Group. In a fast-growing maritime digital market, this acquisition firmly consolidates the Group’s leadership, while creating value for shareholders.
The management team of Danelec will join GTT as part of the leadership of the combined Digital division, ensuring continuity while supporting the acceleration of growth. Over the long term, the integration of Danelec into GTT's Digital division is expected to unlock substantial synergies by combining the complementary technologies and offerings of Danelec, Ascenz Marorka, and VPS. With a strengthened installed base of approximately 17,000 vessels, the Group is ideally positioned to expand its global footprint and enhance its data-driven services for shipowners and operators.
Danelec has undergone a remarkable transformation during the past five years establishing a leading position as a global provider of digital solutions to the maritime industry. Since its acquisition by the European private equity firm, Verdane, in 2020, Danelec has increased revenue by nearly 250%, scaled its installed base by more than 180%, and expanded its technological capabilities through strategic acquisitions.
Through the acquisitions of Kyma (Norway), a pioneer in digital ship performance monitoring; Nautilus Labs (US), a SaaS-based leader in AI-driven vessel and voyage optimization; and MacGregor’s (Germany) VDR business, Danelec has transformed into an end-to-end maritime data and analytics platform. These acquisitions have broadened its capabilities, expanded its global footprint and positioned the company to take a leading role in leveraging high-frequency, high-quality data to drive digitalization and efficiency across the maritime industry.
Today, Danelec’s installed base counts more than 15,500 vessels worldwide, having captured more than 1.5 trillion onboard data points in 2024 alone. This deep foundation of onboard expertise - spanning safety, performance and vessel data collection - uniquely positions Danelec to join GTT to navigate the next phase of maritime sustainability.
With the International Maritime Organisation (IMO) targeting net-zero greenhouse gas (GHG) emissions by 2050, the maritime industry stands before a pivotal opportunity to enhance operational efficiency and unlock significant cost reductions. Danelec’s scalable digital infrastructure empowers operators not only to meet evolving compliance demands, but also to drive measurable environmental and operational gains at scale.
This strategic combination represents a shared ambition: to create the most comprehensive and innovative digital platform in the maritime sector. For customers, it means faster innovation, broader capabilities, and even greater impact on their journey toward carbon neutrality. For employees and partners, it marks the beginning of a new and exciting chapter - backed by global scale, deeper resources, and aligned vision.
"Danelec’s transformation over the past five years has been highly impressive, and Danelec’s management team have been instrumental to this journey and have executed with focus, resilience and strong technical depth. We’re proud to have been a part of this journey and are excited to see Danelec take the next step alongside GTT."
- Arne Handeland, Senior Advisor at Verdane

In a fast-growing maritime digital market, this acquisition further consolidates our leadership, while creating value for our shareholders."
- Philippe Berterottière, Chairman and CEO of GTT
