The total area of the ETFE roofs on both ships is about 4,000sqm. Three-layer, transparent ETFE foil cushions span over the pool and leisure areas of the activity decks with their “4 Elements” and “Beach Club” centrepieces. Movable roof sections enable the areas of the “4 Elements” to be opened to the sky. Vibrations from the ship’s engines, acceleration forces due to the motion of the ship, high wind loads some 50m above sea level, the marine climate with its corresponding salt concentrations plus the different climate zones place tough demands on the materials and combinations thereof as well as the structural design and the detailing. ETFE foil roofs in shipbuilding are new, which is why the necessary engineering solutions represent a huge challenge.
Once again seele lives up to its role as a pioneer in the field of innovative membrane construction by realising this unique project.
