What Ascenz Marorka does

Ascenz Marorka is the smart-shipping digital solutions subsidiary of GTT Group (Euronext Paris: GTT), formed from the 2020 merger of Singapore-based Ascenz (electronic fuel and bunkering monitoring, founded 2005) and Iceland-based Marorka (vessel performance management, founded 2005), with its headquarters in Saint-Rémy-lès-Chevreuse, France. The company provides a modular Smart Shipping Platform serving LNG carriers, oil and product tankers, bulk carriers, container vessels, RoRo vessels, cruise ships, offshore support vessels, and coastal vessels, with a customer base of more than 160 shipping operators worldwide and combined coverage of over 3,000 equipped vessels across Ascenz Marorka and its Vessel Performance Solutions (VPS) subsidiary. Its product suite includes Electronic Fuel Monitoring, Vessel Performance Management, Weather Routing and Voyage Optimisation, LNG Cargo Management (boil-off gas optimisation, heel optimisation, roll-over prevention), the Sloshing Virtual Sensor (AI/ML-based LNG tank sloshing prediction with tank digital twin), the ShaPoLi Shaft Power Limitation solution, and dedicated compliance reporting for CII, EU ETS, FuelEU Maritime, and IMO regulations.

The technology stack combines automatic high-frequency sensor data collection (with both sensor-based and sensor-less acquisition via VPS), Bureau Veritas type-approved cyber-security, and machine-learning-driven analytics layered into vessel digital twins and route optimisation engines, supported by 24/7 Real-Time Fleet Performance Monitoring Centres in France (opened October 2023), Singapore (December 2024), and Vancouver (March 2025). Ascenz Marorka monetises primarily through multi-year enterprise subscription contracts for the Smart Shipping Platform and VESPER platform, supplemented by technical services agreements for LNG-powered fleet maintenance and operation (e.g., CMA CGM's 49 LNG-powered container vessels). Distribution is layered: enterprise direct sales via the GTT Group, a global strategic partnership with Emerson Marine Solutions for Coriolis flow and density meters, OEM integration into newbuilds at Hudong-Zhonghua Shipbuilding and Dalian Shipbuilding Industry, and six regional channel partnerships added in 2025 across Turkey, Greece, Brazil, Malaysia/Singapore, India, and South Korea.

In 2025, Ascenz Marorka, VPS, and the newly acquired Danelec (over 15,500 installed-vessel base) were consolidated into GTT Marine, a new division within GTT Group, signalling a deliberate roll-up into a single maritime digital platform spanning VDR, shaft power meters, vessel performance management, LNG cargo digital twins, and shore-side monitoring services.
