Question:I am calculating the stability for the crane lifting requirements in 46CFR 173.025 for a vessel on exposed waters using counterballast. How do I include the factor "K" in my calculation. The requirement is A2 > A1 + K. Using the residual ratio limit I can determine A2/A1, but I haven't been able to figure out how to include "K" in my calculation. Do you have any advice or an existing run file to do these calculations?Answer:Since 46CFR 173.025 is really wanting the residual area from "theta(c)" to "theta(f)" to be at least "K" (A2 - A1 > K), you can use the LIMIT AREA command:LIM AREA FROM 0 TO FLD > 7.0SOLVESTATUS `<-- if you want to show the condition before dropping the loadDELETE "HOOK LOAD"SOLVE TRIM | STATUS `<-- shows the condition immediately after dropping loadRA 0 2.5p /LIM `<-- change the "p" to "s" if heeled to port with load
