Paris, 10 July 2025 – Ascenz Marorka, a Smart Shipping company of the GTT Group, has been selected by LD Armateurs (LDA) to equip four RoRo2 vessels with its advanced Voyage Optimisation solution. The agreement covers three new-build RoRo vessels currently under construction and the existing RoRo Ville de Bordeaux. 

The solution, enhanced with dedicated features for wind-powered ships, will enable LDA to maximise the performance of its wind propulsion systems. It also provides access to Ascenz Marorka’s Real-Time Fleet Performance Monitoring Centres, where experienced mariners oversee vessel performance and safety around the clock. 

LDA’s decision to adopt Ascenz Marorka’s solution was driven by key criteria: seamless integration of wind propulsion systems into the ship’s digital twin (including sail performance via polar curves), highly reliable weather forecasting, as well as a user-friendly interface designer for crew operations. These capabilities are instrumental in supporting LDA’s operational excellence and its strong commitment to innovation and decarbonisation. 

The collaboration is the result of a trial period over more than a year between Ascenz Marorka and LDA. Following initial trials ashore in April 2024, the Voyage Optimisation solution was progressively rolled out onboard the Ville de Bordeaux in early 2025. Operating on transatlantic routes, the vessel provided an ideal testing ground to validate both the accuracy of the digital twin and the ease of use for crew. 

Philippe Berterottière, Chairman and CEO of GTT stated: “We are proud to support the digitalisation of LD Armateurs’ fleet with Ascenz Marorka’s Voyage Optimisation solution. By integrating wind propulsion systems into our advanced digital platform, we demonstrate the power of cutting-edge technologies to boost operational performance and accelerate the decarbonisation of maritime transport. Partnering with a forward-thinking ship-owner like LDA, whose values align with those of the GTT Group, is particularly rewarding.” 

Samira Draoua, CEO of LD Armateurs, added: “Choosing the right routing software is a key decision for LDA, it allows us to fully leverage wind propulsion, contributing directly to the reduction of CO₂ emissions, thus delivering the decarbonated service expected by our clients. We value our collaboration with Ascenz Marorka and the broader GTT Group, in deploying this advanced solution. Looking ahead, we are also exploring the implementation of similar routing technologies across other vessels in our fleet, even if not equipped with sails, as part of our continuous efforts to optimize fuel consumption and enhance environmental performance.”
