Length of leg on deck


Q: What do you mean by "length of leg on deck" in the jacket launch analysis output?
REV 5.08

A: Length of leg on deck is the distance from the rocker pin to the trailing edge of the jacket. This is always measured along the jacket leg, regardless of jacket orientation. To determine when a jacket support point passes the rocker pin, you need to equate the length of leg on deck to the distance from the trailing edge to the support point. The string function &POINT(d_node *n1 *n2) is useful for this. If you were to use the automated launch macros, the load cases would be generated automatically for you, as each support point passes the pin, and as each midspan point passes the pin. If you allow the simulation to go beyond separation, the macro also creates load cases at maximum post separation velocity, to capture drag dominated members.
