The deck is of the integrated type with all equipment installed onshore in the construction yard. It is composed by 4 main levels, equally spaced about 3.0 m vertically. The main dimensions of the deck levels are 20.0 m by 25.0 m. The deck is equipped with two skidding beams suitable for supporting the drilling rig. The topside includes a technical room, a platform crane, a vent and a telecommunication mast.
