The MAXSURF Stability module provides fast, graphical and interactive calculation of intact and damaged stability and strength for all types of MAXSURF designs.And see next page for more comprehensive details and updates.
Intact and Damaged Hydrostatics and Stability
Once a design has been modelled using Modeller, its stability and strength characteristics can be assessed using the Stability analysis module. Stability provides the MAXSURF user with a range of powerful analysis capabilities to handle all types of stability and strength calculations. Precise calculations are performed directly from the trimmed MAXSURF NURB surface model without the need for offsets or batch file preparation.
All functions within Stability are performed using a graphical multi-
An integrated load case editor makes setting up any number of loading conditions simple and error free. Copy and paste data exchange to and from spreadsheets also makes it easy to prepare complex loading schedules in other programs and run them in Stability. Load cases can also be saved and reused with various design configurations.
Tank and compartment modelling is integrated within Stability making it fast and easy to define the vessel’s tank and compartment layout. More complex compartments can be defined using surfaces modelled in MAXSURF. Tanks are automatically included in the weight schedule and their parametric definition means they are automatically updated if the hull shape is changed as the design progresses.
A tank calibration option is provided to give detailed volume and CG characteristics of all tanks.
Stability includes intact and damaged options for a range of analysis methods including upright hydrostatics, large angle stability, equilibrium analysis, KN tables and cross curves, limiting KG and longitudinal strength analysis. For each analysis method, Stability automatically highlights the required data to be entered and provides data entry dialogs to ensure data is entered correctly.
A wide range of stability criteria can be used to ensure compliance with class requirements. As well as providing the most commonly used standard criteria, Stability allows you to define your own custom criteria for any special requirements. When used in conjunction with Stability table of downflooding points, this provides a complete range of options for satisfying class.
Once an analysis has been run, all results are also presented in tabular or graphical form. You can click on any graph and drag with the mouse to obtain precise values at any location. You can also choose how tables are displayed, which columns are visible and sort results by any column.
An automatically formatted on-
The wide range of analysis, data entry and data display options within Stability make it an indispensable tool for designers of all types of vessels. For designers with a limited budget, the basic Stability suite contains only the intact hydrostatics and large angle stability analysis methods.
