2. MAXSURF Overview Integrated suite of naval architecture applications
Common 3D model for all applications
Change flows through from model to analysis
Consistent, modern, graphical UI across all apps
Easy to learn and pick up and use
Full coverage of all naval architecture functions
Maxsurf is a suite of applications for all aspects of naval architecture

3. Applications for all Naval Architecture functions
All work from a common 3D NURB model:
All of the applications work from a common 3D NURB surface model. This helps naval architects

9. MAXSURF Motions
Prediction of vessel motions using strip theory. Good for motions predictions of FPSOs and other ship-shaped vessels. Fast and easy for proposal work, note however that it is not (yet) not a full motions package like Moses, Seasam or AQWA.

10. MAXSURF Motions: Motions Prediction
Inputs
Maxsurf Model, Remote Locations
Multiple Headings, Speeds, Sea States
Output
Response Amplitude Operators
Motion sickness Index
Time Series Animation
Validated against tank testing
Versions
Basic – Strip Theory
Advanced – Adds Panel method
See slides .. To .. For more details on Seakeeper.

11. MAXSURF Resistance: Wake and Power Prediction
Prediction of resistance and wavemaking
Prediction of power requirements of vessels. Either based on regression analysis of tank test data or a CFD potential flow code built in. Also good for predicting the wake created by a vessel.
