The Argentine shipyard Tandanor, located in the Dársena Sur of the Port of Buenos Aires, has concluded the comprehensive repair of the oil tanker Helios, a vessel measuring 145 meters in length and 23 meters in beam. The ship was involved in a collision with the chemical tanker Ginga Bobcat in the Port of Campana in May 2026.
According to the naval facility, the work included the structural recovery of areas affected by the impact, work on the propulsion system and shaft line, renewal of piping and auxiliary systems, comprehensive hull treatment, and a complete program of inspections and quality controls.
The most complex intervention was concentrated on the starboard stern, where AH-32 grade naval steel plates and various structural elements damaged by the collision were replaced. The tasks also included the reconstruction of supports and foundations, the renewal of different deck components, and work on the purifier room and other affected spaces.
In parallel, shipyard specialists carried out the dismantling, inspection, and assembly of the propeller, controls on the shaft line, measurements of the steering system, and interventions on various mechanical mechanisms related to the ship's operation.
The repair also included the renewal of piping corresponding to different service systems, comprehensive hull treatment using hydrojetting and painting, technical cleaning work, maneuvers on the anchor chains, and an exhaustive program of non-destructive testing and inspections aimed at verifying each of the repairs carried out.
The intervention required the coordinated participation of Tandanor's different technical areas and allowed the Helios to return to service after completing all the controls and inspections required for its operation.
It is worth noting that the chemical tanker involved in the accident with the oil tanker Helios was also repaired by the same shipyard, a process that was completed in early July.
