Marine containment specialist GTT Group acquires Danelec
GTT has signed an agreement with the European investment fund Verdane to acquire Danelec, a leading provider of advanced digital solutions for maritime data collection and analysis.
GTT, based in Saint-Rémy-lès-Chevreuse, France, is an engineering company specialising in marine containment systems for transport and storage of LNG, designing cryogenic containment systems for the maritime industry. It operates in three key sectors: high performance liquefied gas containment systems, smart shipping software and services, and the development of low-carbon technological solutions.
This acquisition fully aligns with GTT’s development strategy in the digital field and brings the Group’s installed base to approximately 17,000 vessels. 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.
Philippe Berterottière, Chairman and Chief Executive Officer of GTT, said:
We are delighted to welcome Danelec to the GTT Group. This acquisition fully aligns with our development strategy in the digital field and marks an important milestone for the Group. Danelec is a recognised player in the maritime digitalisation, with a strong reputation, a significant installed base, and high-quality management team.
“With this transaction, GTT becomes the global leader in the high-growth segment of vessel performance management and positions itself as a leading player in the strategic VDR market. In a rapidly expanding digital maritime market, this acquisition further strengthens our leadership position, while creating value for our shareholders.”
Danelec, founded in 1995 in Farum, Denmark, is an expert in maritime safety and digital performance solutions.
The company initially specialised in the development of critical maritime equipment, particularly Voyage Data Recorders (VDRs), genuine “black box” for ships, before moving into safety and performance software. These solutions enable ship-owners, charterers and fleet managers to make real-time, data-driven decisions, contributing to safer and more efficient maritime operations. Its systems are currently installed on over 15,500 vessels worldwide.
The company, which was acquired by the European private equity firm Verdane in 2020, employs 168 people and relies on a network of more than 700 technicians across the globe, ensuring local deployment and support on an international scale.
Arne Handeland, Senior Advisor at Verdane, commented:
“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.”
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.
Casper Jensen, CEO of Danelec, concluded:
“Over the last few years, we’ve transformed Danelec into a performance-driven, digitally native platform that is trusted by thousands of vessels across the world. This transformation has been made possible by the dedication and collaboration of our incredible team. By joining GTT, we take a bold step forward – doubling down on our mission to lead the maritime industry into a smarter, safer, and more sustainable future.”
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.
