Maxsurf Stability does not have per-defined stability criteria for my vessel
The way we have approached the stability criteria evaluation in Maxsurf is to provide as many of the commonly referenced calculations: eg area under GZ curve; value of GZ at … ; angle of … ; etc – as 'parent criteria'. These calculations have many different, user configurable parameters. The aim is that these parent criteria cover the vast majority of criteria that are used by certification and class societies around the world. It is simply not possible for us to program every permutation of criterion for every code from every classification society around the world.
In addition to the parent criteria, we provide some samples of how these can be applied to specific codes. These samples are included with the Maxsurf installer along with sample ship models, examples of automation scripts etc. These examples of implementations of specific criteria include IMO IS code, SOLAS, etc. However, the vast majority of class societies do not certify design software and very often the codes are open to some interpretation. For these reasons these are examples only. Every user should carefully review the criteria to make sure they agree with our interpretation; and in any case many of the criteria have model-specific parameters that need to be adjusted. Please refer to the Maxsurf Stability manual for full details on how to copy and modify parent criteria, and the scope of the calculation of each parent criterion.
The criteria evaluation in Maxsurf Stability is designed so that users create their own criteria sets, either from scratch or using our examples as templates. If there is a missing type of calculation, which occurs from time to time, then we do our best to provide a new parent criterion which covers this scenario in an update to the software. A case in point is the modifications that were made to the STIX calculation and we have provided a new version of this calculation to cover this in MAXSURF 23.05.
