AFT OPT

LR-Shipdesign AG in cooperation w/Movena GmbH present the application of new findings of fluid sciences in order to significantly reduce the overall ships’ resistance, to improve the propulsion and reduce the main engine power demand.

"AFT OPT" technology applied to ship hulls originates from the transfer and application of principles used in the design of aircrafts. The application of these physical principles to hydrodynamical and hydromechanical principles using proprietary CFD software leads to a new design approach for the aft hull. Hull shape and lower hull resistance lead to a much better filled propeller disk, wake flow and rudder characteristics.

Result: reduction of main engine power demand for same cargo load, speed, draft, by at least 6% compared with so called “latest optimised design” which was based on traditional or proprietary design technologies. In some cases (tanker, bulker), minor modifications of the main engine room might be required in line with the main engines’ manufacturer’s requirements.

Analysis of all ship model basin test result shows, that full scale results for the real vessels will be better than in model scale.
