  How We Use Maxsurf  |  Kasten Marine Design  

The Maxsurf suite of programs fall into three basic categories that follow our work-flow

Maxsurf Stability (Hydromax)

Stability analysis of the Maxsurf model is handled by Maxsurf Stability (previously called Hydromax). 

Maxsurf Stability provides equilibrium analysis, specified condition analysis, large angle intact stability, damaged stability, longitudinal strength, grounding condition strength and stability, tank loading, tank calibration and several other modes of analysis. Further, stability may be assessed in any user specified wave form. 

Partial flooding of tanks and compartments allows the contents of any tank or compartment to be either retained, or dumped.  Windage profile surface groups can be defined, and windage areas respect trim differences and holes in the projected total area, as well as variations in the heeled windage profile.

The Maxsurf Assembly Tree is available in Maxsurf Stability so that the various Maxsurf Modeler assemblies can be shown or hidden as needed. In support of creating the hydrostatics model accurately, Maxsurf Stability is able to display background images or DXF files, facilitating tank and compartment definition in any view.

Comprehensive and user configurable world wide stability criteria are built into Maxsurf Stability Advanced (previously Hydromax Pro). It is therefore possible to perform a Limiting KG analysis based on any user selected stability criteria, a useful capability in order to determine the upper limit of a vessel's VCG early 0n in the design process before the final VCG is known.

The final report accumulated by Maxsurf Stability can be sent to Microsoft Word and formatted and edited as needed, or a batch analysis of all load cases can be automatically sent out to Excel for further analysis or presentation.  Heeled views can be displayed from any viewing angle and also included in the Maxsurf Stability report.  Maxsurf Stability can also export to a variety of CAD formats, including DXF and IGES in order to create accurate CAD drawings depicting various analysis results. 

Data exchange with collaborators during the design process is made easy, especially since Maxsurf Stability can directly import a GHS geometry file for analysis.  As well, a Maxsurf Stability model, including tanks, compartments and critical points, can be exported to a GHS geometry file for analysis by others.

Maxsurf Stability supports multiple processors and 64 bit operating systems, making it quite fast on newer computers.

In summary, Maxsurf Stability is an extremely enabling tool... one that we use extensively throughout the design of all vessels created by Kasten Marine Design, Inc.
