Next steps for the Concordia

Time is running short for the next act in the Costa Concordia saga.

Italian authorities have given the go-ahead for marine salvage companies to try to tip the massive ship up off its sloped resting spot and onto a platform shelf constructed on the seabed. Once vertical, workers will be able to weld caissons onto the starboard side that will be used to refloat the ship.

The tipping maneuver, called parbuckling, may be the trickiest part of the entire operation. And despite gaining approvals, the salvage companies may yet hold off on the operations.

Delays have been the rule rather than the exception in righting the Concordia. Initially the ship was to have been raised and towed away in January, a date that slipped to March and then to September.
