Design of the main connections
1. Moment connections, necessary to link the main
columns to the beams
2. Splice connection necessary to
a) link the corner piece of the vessel to its column
b) ling the horizontal beams
3. Reduced splice connection necessary to link the
shorter beams transversal to the main frames
