FRENER & REIFER is responsible for the design-engineering, fabrication and installation of the 970 m² 105 ton glass dome for P&O Cruise’s new ship IONA.
Self-supporting dome roof glazing for the atrium of the luxury cruise ship IONA. The glass roof has an elliptical 41 m x 29 m (L x W) footprint, a height of 4 m and weighs 105 tons. It was assembled directly next to the ship in the Papenburg shipyard and then lifted onto the 18th deck of the ship in one manoeuvre using a 750 ton crane.
