35/44DF CD: The full spectrum of power

35/44DF CD: Dual fuel auxiliary genset with zero compromises 

In the rapidly evolving marine market, a versatile auxiliary genset can make a difference to your ship’s economic and environmental performance. But only if it can provide a complete range of strengths: high power, fuel flexibility, low methane slip, future-proof technology, and competitive CAPEX and OPEX. 

With our state-of-the-art engineering, we at Everllence created the new 35/44DF CD (former MAN 35/44DF CD) engine that delivers the full spectrum. It can adapt to the most varied genset applications and is ready for future methanol use, CO2 reduction, and the “Fit for 55” climate package.

Higher power, better configuration, fewer gensets 

The advantages of the powerful 560 kW/cylinder output are easy to demonstrate using a typical LNG carrier as an example. Instead of needing four gensets to cope with the high load demand of cargo unloading and port operation, (e.g. 2x6 + 2x8 cylinders at 480 kW), the work can be done with just three 35/44DF CD GenSets (3x8 cylinders at 560 kW). 

With this setup, the LNG carrier needs only one genset for normal operation. The other two are kept for cargo loading and unloading. This saves operation hours, fuel, and emissions, in particular methane slip. It also lowers investment costs and space requirements.

Quote
“ The 35/44DF CD was developed in close collaboration with our licensees and is based on shipyard needs to meet all demands: low CAPEX, digitalization, easy integration, low emissions, and full flexibility for the future, e.g. methanol operation. ”

Marita Krems, Senior Vice President Head of Four-Stroke Marine & License

Engineering the evolution together with our customers

From dual fuel reliability to full spectrum performance, the new genset is based on the 35/44DF CR (former MAN 35/44DF CR) and 32/44CR (former MAN 32/44CR), proven with millions of hours in the field. 

We have built on the base engine elements, which ensures the safety of the genset and low maintenance needs. We have also made upgrades to key application components, improving quality, making installation faster, lowering both CAPEX and OPEX, and generally making operation, installation, and maintenance more convenient. 

The 35/44DF CD (former MAN 35/44DF CD) is developed and tested together with the STX engine and allows licensees to implement their own sourcing concepts.

Upgraded components

  • SaCoS 5000: The engine control system ensures future-proof digitalization with CAPEX-optimized, state-of-the-art cybersecurity, available from 2025.
  • State-of-the-art cybersecurity: Up to SL3
  • Mk3 fuel injection system: Robust design, with over 2,000 units in operation. Saves on cost and emissions, and is compatible with future fuels.
  • Pilot fuel oil pump: Direct drive pump prevents blackouts and optimizes CAPEX.
  • Combustion strategy: Increased power and reduced methane slip
  • Cylinder top cover: Modular design for easy maintenance of cylinder head, air intake and gas pipe, and full methanol upgrade  

Low methane slip 

We have made several important design changes. We reduced the crevice volume, realized up to 35% engine load, and updated the combustion process. 

All these technologies are available as standard. All load points are secured with the lowest methane slip. You benefit from plug-and-play and worry less about engine adjustments. The result is an up to 85% lower methane slip compared to current industry standards. Be ready for future regulations and taxes.
