A diver has died while working on the shipwrecked Costa Concordia in Italy.

The consortium of firms working to prepare the Concordia for removal says the Spanish diver died Saturday while working underwater in the area around the wreckage site. In a statement carried by the ANSA news agency, the Titan Micoperi consortium said the cause was under investigation.

Salvage crews are working to affix huge tanks onto sides of the Concordia to float it off its false seabed and tow it to a port for eventual dismantling. The timetable calls for removal in June.

Thirty two passengers and crew died when the Concordia slammed into a reef off Tuscany and capsized Jan. 13, 2012.

The Concordia was righted in preparation for removal during a remarkable engineering feat last fall.
