Giglio, Italy (CNN) -- Francesco Schettino, the captain of the ill-fated Costa Concordia cruise liner, wants to get back on the ship. His lawyers Monday formally asked a panel of three judges for permission to tour the ship's bridge and engine room as part of a defense strategy that he says will prove that was not the only person responsible for the disaster. 

The liner, which crashed on the rocks off Giglio Island in January 2012, killing 32 people, was rotated back to vertical last Monday. The unprecedented maneuver, called parbuckling, exposed a twisted mass of metal, dotted with mattresses, passenger luggage and deck chairs on the ship's previously submerged starboard side. Now that the Concordia is upright, there can be further investigation of the captain's alleged mishandling of the ship.

Defense lawyers for Schettino agreed with lawyers representing more than 200 civil parties against the captain, including Giglio Island and several passenger and environmental advocacy groups, in asking for a new examination of the ship now that it is upright. Such an examination could include divers going deep into the belly of the vessel to examine whether watertight doors sealed properly, and whether automatic generators functioned. He also wants to walk the judges through the command bridge in a re-creation of the night of the crash. Half of the command bridge was submerged for 20 months. 

The trial began with preliminary hearings last March, but Monday was the first time the court heard any substantial evidence in the case. A panel of maritime experts addressed the role of the Indonesian helmsman Jacob Rusli Bin in the accident. Rusli Bin and four others were convicted in a plea deal in July for their role in the disaster. A Florence court is considering the validity of those plea bargain agreements.
