We are trying to verify the results of probabilistic damage stability done in NAPA along with the result from Maxsurf as part of the product evaluation. We see that there is no option to get the final floating condition of the vessel after damage as required by SOLAS. Can you please advise if there is an option to get these results or is this a drawback of Maxsurf?
Do you have a reference to the SOLAS requirement so I can check up on it? Is your class expecting the heel, trim, draft information for every single probabilistic damage case?
You can copy Probabilistic Damage cases to be Deterministic Damage Cases. You could then run equilibrium on these cases and get the damage equilibrium conditions.
To copy them across, with the Prob Damage Cases tab active, use Case | Copy Prob Damage Cases. If no cases are selected / highlighted, you will copy all the cases. If some are selected then you will copy those rows only.
For any requirements of Class, we can always add these features as enhancements. If they are a feature that you think would be useful we can consider adding it.
This is a requirement from DNV for probabilistic damage stability. Copying the probabilistic damage case to deterministic condition is not the right approach since the volume of the water inside the damaged compartment cannot be found based on probabilistic case and hence, this approach is not acceptable to Class.
You may have to consider adding this feature since Class are actively asking for these results. We are looking for a software that can give us all the outputs that we need.
In addition to the above, the definition of the different types of openings/ key points is not explained in the support file. The key points/ openings are usually defined as unprotected, watertight and weathertight openings in the industry. This is a new type of definition that we have noticed. Can you please define what each of these key points refer to.
hi Vivek, for most of the key point types, they are just labels, a way of categorizing them, but they dont have a special meeting. The original 'types' came from discussions with users in Australia about 20 years ago. We have thought about allowing users to customise the names according to their requirements, but that has not been implemented.Only the last 2 types have special use: "WoD freeboard Point" (used for water on deck calculations) and "Outflow point" (used with spilling tanks)
