GTT, technology for a sustainable world

For over 60 years, GTT has been developing cutting-edge technological solutions for greater energy efficiency. We bring our passion for innovation and technical excellence to the service of our customers, to meet their transformation challenges of today and tomorrow.

We design cryogenic membrane containment systems for the transport and storage of liquefied gas, digital solutions to improve the ship performance, consulting services, training, maintenance assistance and technical studies. We ensure the highest system performance by offering comprehensive support before, during, and after construction, leveraging the knowledge and know-how of our experts.

More than ever engaged in the energy transition, GTT is committed to the development of hydrogen through its subsidiary Elogen, which designs and assembles electrolysers for the production of green hydrogen, and by developing our very first liquefied hydrogen carrier.

The GTT teams are at the heart of our mission. Committed and united, we are determined to contribute to the construction of a sustainable world.

Ascenz Marorka has resulted from the merger of two pioneering companies in the digitalisation of the maritime industry: Ascenz, a Singaporean company with a strong experience in Electronic Fuel and Bunkering Monitoring, and Marorka, an Icelandic expert in vessel performance management, data acquisition and modelling. These two companies were acquired by GTT Group respectively in 2017 and 2020.

Through the combination of these companies’ expertise we offer a full range of end-to-end solutions for ship owners and charterers around the world.
