SAVANNA,
The latest version of PV Elite/CodeCalc considers the analysis of lifting trunions in accordance with WRC 107 as part of its overall features.
From the CODAE/HEXAGON Website:
A hollow or solid circular trunnion with or without pad reinforcement can be analyzed using the Trunnion Design module. The main considerations regarding the trunnion design are stresses at the vessel/trunnion junction and on the trunnion itself. Bending stress, shear stress, bearing stress and unity check are calculated and compared with the appropriate allowables. Local stresses at the junction can be analyzed using the WRC 107 Analysis Selection check box. The lifting orientation, vertical and horizontal positions, and the orthogonal input forces are needed for WRC 107 Analysis.
Does that answer your question ?
There are also long-established manual methods to perform an analysis of vessel lifting trunions.
As I recall, they incorporate methodologies contained within Roark, "Formulas for Stress and Strain"
