Clean Products Tankers Alliance (CPTA) has agreed a deal with GTT Group company Ascenz Marorka to deploy its weather routing system across its entire fleet.
CPTA, a medium-range product tanker pool company, operates approximately 20 vessels.
The Ascenz Marorka weather routing software calculates optimal shipping routes by integrating multiple economic and environmental variables, while taking into account a range of operational and regulatory constraints. This technology is compatible with various vessel types and propulsion systems, regardless of the fuel source chosen.
CPTA already uses the Ascenz Marorka Smart Shipping platform to monitor the performance of its fleet. This new contract will provide access to the weather routing module and the assistance service provided by the Ascenz Marorka Real-Time Fleet Performance Monitoring Centre.
“We are pleased to extend our cooperation with Ascenz Marorka by enrolling our fleet in their weather routing service,” said Jhander Marval, Head of CPTA Operations, and Bas Blaak, Head of Energy Efficiency and Sustainability at CPTA.
“Digitalisation and innovation are key to support our operational excellence and achieve our economic and environmental objectives. This initiative is part of our ‘every ton counts’ strategy to continue reducing greenhouse gas emissions.”
