Padeye design and calculation mermaid-consultants.com . padeye design and calculation. Each lift point consists of a padeye which is welded to the structure and connected to the sling by a shackle. The lifting force acting on the padeye is caused by the weight of the structure and the equipment used. This lifting force is transferred.

A simple and conservative approach is to calculate the length of a single shear plane as: L sp = a where a = R − 0.5 D h, as shown in the figure above. If it is desired to account for a slightly longer shear.
