Can rhinomarine cauculate Cross curves of stability?

I have readed the manul of rhinomarine ,but i didnot know how to cauculate cross curves even it can cauculate righting Arms cruves

 

I haven't seen cross curves in RhinoMarine, but the hydrostatic report is written to an xls file, so you may add it yourself, probably into a template so it's always there.

 

thx Raggi!

 

Hi Ragnor,

Could you give us the cell formulas you use to do this? Or maybe the template, as I am a lazy guy and there is so much data in that report I'm not at all sure where the best place to start is (I'm using RhinoMarine 4).

Thanks!

Run the analysis for a range of flotation planes, simply take your cross curves from the data for each heel angle for each displacement and plot a new graph accordingly.

You may need to compartmentalize your tanks and assign the COG accordingly for worst case since I don't think rhinomarine has "free surface" .

 

Thanks Mike!

 

Leak stability in RhinoMarine

Could this be a suitable solution:

First, calculate hydrostatics with a sound hull and pick up displacement and LCB.

Then cut off the leaking compartment of the model and calculate hydrostatics/CG (use previous LCB and displacement). The model trims and heels nicely.

 

Thanks from me also Mike
