Ship retrofit: An intelligent solution for decarbonisation


TecnoVeritas turns environmental challenges into operational advantages through high-performance marine retrofit engineering.

ecarbonisation is a regulatory and market-driven need rather than just a choice. Shipowners face increasing pressure to reduce emissions due to IMO regulations, such as EEXI and CII, as well as the introduction of carbon taxation under the EU ETS. However, replacing entire fleets with new vessels is financially unsustainable for most operators. The answer lies in retrofit: the strategic modernisation of existing ships with advanced technologies that extend vessels’ lives, improve efficiency and ensure regulatory compliance. TecnoVeritas has led the way in maritime energy performance for more than 30 years. From technical and energy-focused audits to on-board installation and verified compliance reporting, the company, which has its headquarters in Mafra, Portugal, acts globally and provides integrated solutions by fusing naval engineering, energy diagnostics and distinctive technology.


Creating measurable outcomes from emission targets TecnoVeritas provides a thorough ship retrofitting method with observable advantages, such as: ■ lowering CO2


, NOx, SOx and particulate matter


■ adhering to international regulations including EEXI, CII and MARPOL


■ improving fuel economy and energy efficiency


■ prolonging asset life and raising vessel value


One of TecnoVeritas’ key solutions is BioHFO, a patented fuel processing system that processes traditional fuels (HFO or MDO) with 100% biofuel (B100) using high-intensity ultrasound technology. By reducing CO2


emissions by up to 42%,


this in-line processing system can improve fuel combustion, save operating costs and drastically reduce carbon tax obligations. Another standout project is the SCR (Selective Catalytic Reactor) system retrofit, which has enabled ships like the M/V Vasco da Gama to achieve an 82% reduction in NOx emissions, ensuring full Tier III compliance and access to Emission Controlled Areas.


Demonstrated achievement in practical projects TecnoVeritas has successfully implemented retrofitting projects across a diverse range of vessels – from passenger ferries to cargo ships. In the context of the Portuguese Fleet Decarbonisation Programme, TecnoVeritas equipping 11 vessels with advanced retrofitting solutions, delivering the following average results:


These achievements were made possible by deploying a suite of complementary technologies: ■ BOEM (Blue Energy Efficiency Monitoring): a real-time, cloud-based fleet performance and emissions management platform.


■ Optipower: a shaft power, torque and thrust meter system for propulsion efficiency diagnosis.


■ VFD systems: for energy-optimised electric motor control.


■ Shore power connection systems: SCRs, anti-fouling coating.


Tailored engineering, seamless implementation TecnoVeritas’ retrofit services are customised for each vessel, recognising that no two ships – even sister vessels – are identical. The process normally includes: ■ detailed energy and technical audits ■ engineering design and retrofit integration (mechanical, digital fuel-based)


■ on-board installation with minimal operational disruption


■ Full compliance testing, reporting and coordination with classification societies and flag authorities


TecnoVeritas works closely with shipowners, shipyards, classification bodies, and regulatory agencies to ensure that each retrofit maximises operational and environmental returns. Solutions such as BioHFO not only ensure environmental benefits but also provide immediate savings on carbon taxes and fuel expenditure. ●
