Lower emissions with power plant and ship retrofits
Everllence supports the decarbonization of the maritime and energy sectors through a targeted retrofit strategy that enables existing engines to run on low-carbon and zero-carbon fuels.
With around 1,900 two-stroke and 1,800 four-stroke engines identified as candidates for fuel conversion, our future-proofing solutions help you transition to gaseous or liquid synthetic fuels such as LNG, methanol, ammonia, or hydrogen. These retrofits not only reduce CO₂, NOₓ, and other greenhouse gas emissions but also improve operational flexibility by allowing you to select the most economical and sustainable fuel type available.
Comprehensive ship and power plant retrofit solutions
Everllence offers a comprehensive portfolio of retrofit solutions for two-stroke and four-stroke engines, turbochargers, GenSets, and propellers, engineered for the marine and power sectors. From fuel conversions and digital optimization to propeller redesigns and turbocharger upgrades, Everllence provides end-to-end support to future-proof your assets.
Stay flexible and compliant
We offer a comprehensive suite of retrofit solutions for two-stroke engines, aimed at improving efficiency, compliance, and operational flexibility. These retrofits are particularly relevant for vessel operators seeking fuel oil savings and meeting stringent environmental regulations, such as IMO's EEXI and CII standards.
Key retrofit offerings include powerful engine optimization, full-scale dual-fuel conversions, derating, and propeller optimization. These solutions offer existing fleets significant operational upgrades and extended lifetime while ensuring they meet modern performance and emissions requirements.
A central focus of Everllence’s retrofit strategy is the integration of digital and automation upgrades. Solutions like EcoTuning and EcoCam are designed to reduce fuel consumption and CO₂ emissions by optimizing engine performance across a range of operating profiles.
We also offer full dual-fuel conversions, enabling your vessels to switch between conventional fuels and cleaner alternatives, such as LNG or methanol. These methanol and LNG ship retrofits not only ensure regulatory compliance but also enhance fuel flexibility and future-proof your investments.
Cut costs and emissions
We provide a range of retrofit solutions for four-stroke engines designed to enhance performance, meet evolving environmental regulations, and reduce operational costs. These solutions are suitable for a wide range of marine and stationary applications, including propulsion engines and GenSets, to bring older engines up to current performance standards.The retrofit portfolio of Everllence, with a focus on emissions reduction, fuel flexibility, and efficiency improvements, helps you align with regulations including IMO Tier III, EEXI, and CII, while also optimizing engine lifecycle value.
Our four-stroke retrofit offerings include the integration of selective catalytic reduction (SCR) systems and exhaust gas recirculation technologies to significantly cut NOₓ emissions. We also offer dual-fuel solutions for methanol or LNG ship retrofits, or other alternative fuels, helping you to reduce greenhouse gas emissions and ensure regulatory compliance in emission control areas.
Additional upgrades of engine control systems and electronic fuel injection systems, as well as performance tuning kits, further enhance fuel economy and reliability.
Boost efficiency and compliance
We offer retrofit solutions for turbochargers that boost efficiency, prolong component lifespan, and help to ensure compliance with emission regulations. These are suitable for both two-stroke and four-stroke engine applications, regardless of the engine supplier.
A turbocharger retrofit from Everllence provides you with newer, more efficient models from our latest TCT and TCF generations, helping you to optimize engine performance at part-load conditions, reduce fuel consumption, and lower emissions. This is especially relevant in slow-steaming or load-variable operations.
Everllence supports each turbocharger retrofit with detailed feasibility studies, performance simulations, and end-to-end project execution.
Optimize fuel efficiency
By upgrading and retrofitting existing vessels' Controllable Pitch propeller (CPP) systems, you will achieve better energy efficiency, lower actual fuel consumption, reduced emissions, and support compliance with the latest CII regulations.
With state-of-the-art technology, hydrodynamic know-how, and advanced Computational Fluid Dynamics (CFD) analysis, design and optimization tools, we provide tailored solutions for improved propulsion efficiency – considering the actual propeller configuration, hull and rudder design parameters, and the operational profile of the specific vessel.
Our solutions feature an optimized propeller blade design, often combined with a power limitation introduced in the existing remote control system. Other efficiency-improving devices, such as EcoBulb and fairing cone solutions, are often considered as well. This gives you an attractive decarbonization business case with a short return on investment – keeping vessels competitive in the market for an extended lifetime.
We guide our customers through the entire process, from the initial assessment and clarification of optimization potential to installation and beyond. We're committed to helping you navigate regulatory changes smoothly and efficiently.
