Autopower Resistance and Powering Prediction Program

Autopower‘s advanced user interface enables optimization of hull parameters based upon 12 independent resistance and propulsion methods for displacement, semi-displacement, planing hulls and catamarans.

Graphic User Interface – up to five different hull alternatives can be considered simultaneously, facilitating comparative design studies and optimization. Parameters may be easily changed for quick recalculation. Limits of each resistance prediction method are clearly displayed, providing guidance on the selection of the most suitable methods. Using Windows, Autopower may be one of several programs running at once – a significant time and frustration saver when the effect of a change to the model is to be examined.

Fast Link to Autoship – Autopower has a fast link which enables hull parameters to be imported from Autoship. Hull parameters may also be easily specified by the user.

Export to Word Processing Programs – Edit reports off-line using either the built-in Autoship Report Editor, or export to MS Excel.

Displacement Methods – Andersen & Guldhammer, Holtrop, Fung, van Oortmerssen, Digernes & Cheng, Jin, Su & Tan, Calisal and FAO (UN).

Planing Methods – Savitsky and Radojcic.

Semi-Displacement Method – Compton.

Catamaran Method – FastCat/Marintek.

Propulsion Efficiencies – User-specified or calculated according to Wageningen B-series or Gawn-Burrill KCA series polynomials.

Propeller Optimization – Propeller optimization can be carried out in two modes: for fixed propeller diameter and ship speed or for given delivered power and propeller rpm.

Operating System Requirements: Windows® 10 and 11 Professional (32 or 64 bit), .NET Framework 4.8 with a Pentium Processor. Minimum resolution: 1280 x 800 (WXGA). OpenGL: recommended v3.2 or higher, minimum v2.1.
