Dear All
We have encountered a critical issue with the joints from the beam to the main plate on the Spud Can top plate of our jack-up rig. Upon welding and subsequently lowering the spud can into the water using the jacking system, cracks have emerged in three of the joints that were welded previously ( according to photos cracks happen on the plate) This is a concerning development, and we must address it promptly to ensure the integrity and safety of our spud can.
Considering that in the area where we are, the depth of water is low and there is not much pressure on the spud can, the reason why this happens is not clear to us, and if anyone can advise on this matter, I would be very grateful.
Main top plate thickness is 19 mm and crack depth is 16 mm.
Regards
Babak
