Monster Package

Integrated Design with Combined Energy-Saving Devices

Following the success of the Eco-Cap, our product development has rapidly advanced to include a series of energy-saving devices. These include the Ultimate Rudder Bulb, which recovers hub vortices and swirl flow generated by the propeller, and the Neighbor Duct, which utilizes bilge vortices at the stern to generate additional thrust.
The Monster Package represents a comprehensive solution that combines these devices to further enhance propulsion performance through integrated optimization.

Through a co-development partnership with Becker Marine Systems in Germany, both companies share propeller and energy-saving device geometries, enabling accelerated optimization through CFD analysis and model testing. In self-propulsion tests conducted at the National Maritime Research Institute (NMRI) in Japan, the individual energy-saving effects were as follows: Eco-Cap: 2.9%, Ultimate Rudder Bulb: 3.9%, Neighbor Duct: 4.7%.
When combined was: Eco-Cap + Neighbor Duct: 6.2%, Ultimate Rudder Bulb + Neighbor Duct: 8.7%. These results demonstrate the synergistic benefits of integrated design in achieving significant fuel savings.
