Marorka

What Marorka does

Marorka, now operating as Ascenz Marorka, is a maritime technology company providing AI-driven energy management and vessel performance digital solutions to shipowners, charterers, and vessel operators globally. The company reports 20+ years of maritime domain experience and a base of 3,000+ ships equipped or connected across the combined Ascenz Marorka and Vessel Performance Solutions fleets. In 2025, Marorka was consolidated into GTT Marine, a newly formed division within GTT Group that also includes Danelec and Vessel Performance Solutions, with the legal entity Ascenz Marorka headquartered in Paris, France.

The platform combines automatic data collection infrastructure, onboard sensor and flow meter hardware, and AI-driven maritime analytics to deliver a modular suite of digital solutions. Core offerings include Vessel Performance Management, an Electronic Fuel Monitoring System for fuel consumption and bunkering, Advanced Weather Routing for voyage optimization, and specialized LNG modules covering LNG fuel management, LNG cargo management, the Sloshield sloshing monitoring system, and ShaPoLi shaft power limitation compliance tooling. Additional modules handle reporting and regulatory compliance and advanced vessel performance analysis. Customers are served across a vertical segmentation of LNG carriers (including FLNG and FSRU vessels), ocean-going vessels (tankers, bulkers, container ships, cruise ships, Ro-Ro), offshore support vessels, and coastal vessels (bunker barges, fishing vessels, tugboats). Named wins include a 24-LNG-carrier Sloshield contract with Hudong-Zhonghua Shipbuilding (2025-08-27) and an EFMS deployment on the offshore support vessel A.H. Giorgio P. operated by Grupo CBO (2025-09-18).

Revenue is generated primarily through subscription-style recurring contracts for digital solutions, bundled with hardware (sensors, flow meters), applications, and ongoing services under a quote-based enterprise B2B sales motion. Pricing is not publicly disclosed. Go-to-market is consultative and direct, with a global enterprise field sales approach and channel leverage via shipbuilders for newbuild specification-driven placements. Historical early- and growth-stage capital was sourced via Icelandic Technology Development Fund grants (2004-2016, totaling roughly $1.76M across disclosed rounds) and a 2016 EISMEA round of approximately $54K, reflecting a grant-supported bootstrap prior to absorption by GTT Group.
