If six (6) units of 40 footer container vans filled with blow-foam, fully welded and sealed, and arranged systematically, could this be utilized as an offshore working platform? Like putting an excavator or a clam shell crane on top for dredging?
It would certainly float, but the thicknesses would be too thin for sustained use use. I believe that the metacentric height would be wrong and as it is full of foam you could not ballast it to lower the centre of gravity and increase the draught.
