Barge STB1 – floatover mode

 

This work was carried out for Saipem and had to define the ballast procedure to be used during the floatover topside installation on the top of the Jacket structure, in accordance with specific acceptance criteria. The acceptance criteria concerned the barge trim, heel and stability verification and the timing definition for the transfer of the topside loads from the barge to the Jacket.

A dedicated mooring system was designed for the correct positioning during the floatover operation.
