FOCUS ON: Ascenz Marorka
Apr 24, 2025
Smart Monitoring Solutions for Fuel Consumption & Bunkering
With over 20 years of experience, Ascenz Marorka, a GTT company, stands out as a leader in digital fuel monitoring systems (EFMS) for coastal and offshore vessels. Recognized and approved by major players such as ExxonMobil, Saudi Aramco, and Petronas, their technology is now a standard among operators of tugboats, bunker vessels, and more.
Accuracy at the Core
At the heart of any vessel performance initiative lies one essential element: precise measurement. Ascenz Marorka was a pioneer in bringing mass flow meter-based digital bunkering solutions to market, setting the benchmark for reliable and accurate data—regardless of harsh marine conditions or variable fuel properties like viscosity or temperature.
Their EFMS eliminates common sources of error and underperformance, driving both economic performance and environmental responsibility.
Just like Seavium, Ascenz Marorka believes that real-time, trustworthy data is the foundation for modern decision-making in the maritime world. Where Ascenz focuses on onboard systems, Seavium complements it by providing a platform for smarter vessel selection and chartering, based on verified specs and operations data.
Bunkering: Enhanced Transparency
Digital monitoring during custody transfer ensures that the delivered quantities match contractual obligations. With real-time data, artificial intelligence, and operational know-how, the risk of human error or malpractice is drastically reduced.
Acting as a trusted third party, Ascenz Marorka increases accountability and transparency. A value we also promote at Seavium: the more transparent the operation, the more confidence across the supply chain—from bunker supplier to vessel charterer.
Security by Design
From hardware installation to software protection, cybersecurity and anti-tampering measures are embedded in every layer. Their EFMS is the only system of its kind to be type-approved under IACS UR E27 cybersecurity requirements—a strong differentiator in a time where data integrity is more critical than ever.
Smart Bunkering: AI-Driven Insights
More than a dashboard, Ascenz Marorka’s Smart Bunkering feature provides actionable analysis, driven by embedded AI. In ports like Rotterdam and Fujairah, where short bunker deliveries are a known issue, this technology makes a real difference.
While some authorities are yet to enforce mass flow meters, forward-looking operators can already take control of their data. At Seavium, we share this proactive mindset—digitalisation doesn’t wait for regulations to change; it leads the way.
Beyond Daily Fuel Tracking
Fuel consumption isn’t static, and context matters. Without understanding the operational phase (transit, standby, towing...), raw data is meaningless.
Ascenz Marorka uses AI to break down vessel activity, offering real operational insight.
This is the same ambition that drives Seavium: helping operators not only see data, but also act on it—whether it's selecting the right vessel or understanding consumption drivers at scale.
What’s Next?
The offshore and coastal shipping markets are growing, and digitalisation is accelerating. With hundreds of EFMS deployed globally, Ascenz Marorka is a reference for performance-focused operators.
A Shared Mission: Digital & Transparent Maritime Operations
At Seavium, we share Ascenz Marorka’s commitment to transparency, data-driven decisions, and operational performance.
Together, we are part of a new wave of solutions reshaping how the maritime industry operates—smarter, leaner, cleaner.
Discover how Seavium helps you find the right vessel faster, compare key specs, and manage your fleet with real-time visibility.
