Finland-based marine expertise group Wärtsilä will provide its EnergoFlow and EnergoProFin options for ten Chook Class oil and chemical tankers owned by the Singapore-based international tanker operator Hafnia.
“The mixture of the 2 Wärtsilä programs ensures an optimized waterflow over and after the propeller, thereby enhancing propulsion effectivity significantly. The order was booked by Wärtsilä in October 2023,” Wärtsilä mentioned.
In accordance with Wärtsilä, EnergoFlow is an revolutionary pre-swirl stator that creates an optimum influx for the propeller, decreasing gas consumption and emissions in all working situations.
The EnergoProFin is an energy-saving propeller cap with fins that rotate along with the propeller. It reduces the power losses created by the propeller hub vortex, growing total propulsion effectivity and considerably decreasing underwater noise, Wärtsilä mentioned.

By enhancing the vessels’ gas effectivity, emissions are diminished, working prices are lowered, and each the Carbon Depth Indicator (CII) ranking and Power Effectivity Current Ship Index (EEXI) worth are improved, Wärtsilä defined.
“There are lots of advantages to be gained by enhancing the working effectivity of our vessels’ propulsion programs and we sit up for having these revolutionary Wärtsilä options put in,” mentioned Ralph Juhl, EVP, Technical Director at Hafnia. “At Hafnia we’re working arduous to decarbonize our operations and these retrofitted options will help this dedication.”
“Wärtsilä’s OPTI Design methodology takes benefit of computational fluid dynamics together with our in depth in-house know-how. The EnergoProFin propeller cap and EnergoFlow pre-swirl stator work collectively to ship significant gas financial savings and higher environmental efficiency, that are key ambitions for at present’s main operators,” commented Francois Emin, Product Supervisor – Propulsion, Wärtsilä.
The Wärtsilä tools is scheduled to be delivered beginning in 2024. The undertaking might be carried out over a two-year interval for the ten vessels.
