A 135-meter tanker suffered cavitation damage to the inside shell-plating of one of its ballast water tanks. We mobilized a team to the vessel to perform a permanent insert repair that would prevent an unscheduled drydock visit.
The team sailed with a workboat and all necessary equipment to the ship which lay at anchor in Algeciras.
After arriving on site, our team of diver/technicians started with an on-board and underwater inspection of the damaged area. This revealed that the crack was 150 mm long. In close communication with the superintendent of the vessel and the attending class surveyor, it was decided that a 300 x 300 mm insert would need to be installed.
Repairs like this can be carried out above or below water, according to the circumstances, with external cofferdams. Normal commercial activities can therefore continue without disruption.
If ever you would encounter a similar situation, give us a call. We can then tell you if the repair is feasible and start working on its handling.
