powerHull

powerHull is a cost effective, fast and reliable power requirements prediction tool for new projects at preliminary design stage or vessel repower projects.

Features

• Metric or Imperial units.
• Well enstablished, published prediction methods based on model testing ensure reliable results.
• Prismatic, semi-empirical methods: Savitsky, Savitsky win “M-Factor” (corrected for lower than planing speeds or planing hulls at “hump” region.
• Regression methods: Series 62, Series 65, Mercier & Savitsky, Lahtiharju (VTT), Crouch and Wyman.
• Appendage resistance including rudders, shafts, struts and trim tabs.
• Air drag.
• Unlimited speeds, user defined margin, overall propulsion and transmission gear efficiencies.
• Results include: linear and volumetric Froude numbers, bare hull resistance, appendage resistance, air drag, margin resistance, total resistance, effective power, shaft power, total power, running trim angle, critical trim angle (limit for dynamic instabilities), special comments.
• Plots generation including: resistance to speed, power to speed, trim angle to speed. Multiple method results on the same plot for easy comparisson. Plots can be saved as PNG files to be used in reports.
• Save / Load parameter files for future analysis.
• Results are presented in tabular form and can be saved as a cvs file ready to be imported in a spreadhseet application
