Calculation of Load per Bolt [W/Bolt],
W = TW M = Test Moment

= (( 4 * M/DC ) - W ) / RN per Jawad & Farr, Eq. 12.3
= (( 4 * 0 / 5159.700 ) - 0 ) / 36
= 0.0000 N [** No Uplift ** ]
I want to know why M and W is 0?

Hello liu

If 4*M/DC < W, it means no bolts are in tension, and technically, the bolts could be removed and the vessei will still stand there without toppling over. The programme in that case simply sets the M and W values to zero for convenience.

Incidentally, that equation assumes the bolts are spread out into a thin ring with an equivalent area.

thank you very much. I know it self-stable.but how wo set the anchor bolt?

Hello liu

Just use you best judgement. A 37mm bolt should be about right, but look at the proportions of you vessel.
