Acoustics and Vibrations

Through the participation in many projects with noise sensitive requirements, Eckhard Praefke gained experience in theory and calculation as well as in practice. ISA profits from this experience in new projects.

Scale Model Testing

Scale model tests constitute the ultimate validation of calculations and simulations and therefore minimize the risk of high add-on costs at a later project stage when unsuitable components have been produced and brought into operation.

Shaft Lines / Propulsion Gear

In an ideal approach, propeller, shaft line and ship appendages are jointly designed from the very early project stage in order to be perfectly adapted to each other.

Sea Trials & Operational Data Analysis

Despite new calculation methods, simulations and model testing, only sea trials can give final certainty regarding the actual ship performance.
