ClassNK ZETA platform to offer NAPA Fleet Intelligence modules

Maritime software and data services provider NAPA has expanded its long-term collaboration with ClassNK by offering key NAPA Fleet Intelligence modules via the ClassNK ZETA platform. This integration creates a more powerful, streamlined digital solution for monitoring regulatory performance and optimising fleet operations.



NAPA Fleet Intelligence is a cloud-based solution for ship performance monitoring, optimization, and regulatory compliance, delivering insights to enhance efficiency and safety. ClassNK ZETA (Zero Emission Transition Accelerator) is a platform used to manage ship greenhouse gas (GHG) emissions and regulatory compliance, to which ClassNK has just released new features related to FuelEU Maritime and EU-ETS.

With the integration of NAPA’s modules, shipowners and operators can now access deeper performance insights and compliance simulations using the same data already submitted to ClassNK ZETA. This creates a single platform, with one user account and more functionality for managing ship data efficiently.



With this update, shipowners benefit from a ‘single data, single platform’ experience. Operational data from ships is now shared once and used for both compliance verification and performance analytics, eliminating redundant reporting workflows. The integrated solution enables users to manage fleet data, simulate future compliance scenarios, and monitor performance KPIs — all from one login.



The collaboration also allows users to request the purchase of EU Allowances (EUAs) for use within the EU Emissions Trading System (EU ETS) directly from the ClassNK ZETA platform. Plus, shipping company can minimize FuelEU Maritime penalties by applying the compliance measure optimization algorithm developed by ClassNK and NAPA.



Additionally, users can simulate and monitor the impact of future voyages on their FuelEU, EU ETS and Carbon Intensity Indicator (CII) performances. These highly accurate simulations are built on NAPA’s advanced ship performance model, weather routing and voyage optimization technology.



Naoki Mizutani, Executive Vice President, NAPA Studios, commented: “As a long-term development partner of ClassNK ZETA, the NAPA team has been working on the platform with ClassNK for 1.5 years. By combining ClassNK’s deep regulatory expertise with NAPA’s strengths in ship performance modelling and voyage optimisation, we’ve created a single, user-friendly platform that meets the industry’s growing demand for digitalization, efficiency, and transparency. It's a clear step forward for shipowners navigating the complex regulatory landscape.”



Mr. Katsuya Naito, General Manager, Green Transformation Center at ClassNK, added: “At ClassNK, we are committed to supporting our customers with practical and forward-looking tools to manage regulatory requirements and decarbonization challenges. This integration with NAPA Fleet Intelligence takes ClassNK ZETA to the next level, enabling users to access simulation and optimisation tools directly through the platform. By eliminating data duplication and streamlining access to key insights, we are helping our customers make faster, more informed decisions with less administrative burden.”



Vessels using noon report-based data can now access a broad suite of NAPA Fleet Intelligence features via ClassNK ZETA, including FuelEU Future Voyage Simulation, CII Simulator Future Voyage Simulation, Voyage Optimization, Fleet View, Voyage Overview, Charter Party, Performance Table and Technical Performance modules. For vessels sending voyage report-style data, the FuelEU Future Voyage Simulation, CII Simulator Future Voyage Simulation, and Voyage Optimization modules are available.
