Dual-fuel engines for marine exploration and production

Dual-fuel engines: Reduced emissions, higher efficiency

Due to stricter emission legislation and efficiency requirements, the technologies of floating units are transitioning to modern, more efficient dual-fuel engines. Their ability to use conventional fuels and LNG reduces CO2 emissions for more environmentally friendly operation and improves the total cost of ownership (TCO) for a positive development in all regards.

Floating production storage and offloading vessels (FPSO), floating liquefied natural gas facilities (FLNG), and floating storage and regasification units (FSRU) require a high-availability power source for continuous operation.

For fuel flexibility: 49/60DF (former MAN 49/60DF)

The dual-fuel design and modern engine platform of the 49/60DF (former MAN 49/60DF) make this Everllence engine future-ready – not only in terms of adapting to varying fuel availability on FPSOs but also regarding different gas qualities on FLNGs and FSRUs.

The 49/60DF engine can be used as part of a diesel-electric propulsion and power generation system. It boasts best-in-class fuel consumption and low emissions. With a power output of 1,300 kW per cylinder and a total power output ranging from 7,800 to 18,200 kW, the 49/60DF (former MAN 49/60DF) allows for a reduced number of cylinders and smaller footprint compared to previous dual-fuel engines, resulting in lower maintenance costs and space requirements over its lifecycle.

For low-power demands: The 32/44CR

Our 32/44CR (former MAN 32/44CR) engine is a synthesis of the most advanced large engine technologies and the perfect fit for lower power demands. Suitable for essential generators and other operations with low-power demand, this engine generates a power output between 3,600 and 10,000 kW. The 32/44CR (former MAN 32/44CR) complies with IMO Tier 2 regulations in liquid mode. With our in-house closed loop Selective Catalytic Reduction (SCR) for exhaust cleaning alongside our engines, it can meet Tier 3 requirements in liquid mode.

Dual-Fuel, Electric+ increases cargo capacity and lowers fuel costs

The new Dual-Fuel, Electric+ (DFE+) propulsion concept for LNG carriers brings together the 49/60DF (former MAN 49/60DF) engine and ABB’s Dynamic AC power distribution and control system.

While conventional dual-fuel diesel electric (DFDE) propulsion sets a constant speed over the entire engine load, the DFE+ concept is more flexible by maintaining efficiency throughout the speed range. DFE+ saves machinery space, which can be used to increase cargo capacity. This results in optimized revenue and has a positive effect on the Carbon Intensity Indicator (CII). Yet, DFE+ operation allows for redundant operation by using three to four engines and a battery for maximum power with minimum chances of downtime.

It is also easily adaptable for future FSRU or FLNG operations and future-proof by allowing for easy installation of alternative power sources, such as fuel cells and others in the future.
