The probabilistic damage stability extension developed by DELFTship BV incorporates both the old rules for damage stability as well as the new harmonized rules, MSC.216(82) that entered into force on January 1st 2009.Some key features of our probabilistic damage stability extension are:
- Fully automatic generation of damages based on the zonal approach. Zones can be specified by the user or automatically extracted from the geometry of tanks and accommodation based on several scenarios varying from coarse to fine. Damages are generated for both sides of the ship simultaneously in a matter of seconds, each side having its own subdivision layout based upon the actual internal geometry of the ship.
- Unlimited amount of damage cases. Vessels with more than 20.000 unique damages cases have been successfully calculated.
- Able to handle complex hull shapes
- By using the most detailed subdivision scheme all steps and recesses are accounted for, leading to the highest possible attained index.
- Graphical representation of each damage case clearly showing the damaged compartments, distribution of zones,damage extents etc. The layout of this view can be generated manually or fully automatically ensuring maximum visibility of all compartments.
- Include the effects of cross flooding devices
- Output of results in a summarized report or an extended report. The extended report shows a graphical presentation for each damage case as well as the calculated results for each of the three (or two) draughts, including the corresponding stability curves.
- Various tools to speed up the calculation such as the option to remove damage cases from the set that do not contribute significantly to the attained index.
- Recently hyper threading support has been added to the probabilistic damage stability extension. This technology make use of all the available CPU cores in the computer by solving multiple damage cases simultaneously. This leads to a reduction of the overall calculation time to roughly 50% for dual core processors and up to even 20% for core I7 processors! (see image)
- For dredging vessels all spoil densities can be calculated for both sides of the vessel and two drafts in one single run. All results are stored in the project file for future reference.
