Sarnen, Switzerland-headquartered RO/RO carrier specialist Sallaum Lines, which also has offices in Dubai, recently announced that it is executing a large-scale retrofit program aimed at enhancing the sustainability and operational efficiency of its fleet.
The core of this retrofit program involves upgrading Sallaum Lines’ vessels with the Wärtsilä EnergoFlow system\r and optimized optimized fixed pitch propellers designed to enhance hydrodynamic performance, improving thrust while sailing.
The EnergoFlow is a unique pre-swirl stator that enhances the inflow to the propeller by diverting part of the stern flow in the opposite direction of the propeller’s rotation. This process generates pre-swirl, which helps reduce fuel consumption and emissions significantly.
Sallaum says that the combination of the optimized propeller and EnergoFlow is tailored to the vessels’ operational profiles, ensuring that these vessels can operate with greater fuel economy across various speeds and load conditions. By working together, these systems reduce drag and energy losses, transforming more of the engine’s power into forward motion and
