Abstract: A device for shielding operation and maintenance areas comprises a frame (20) for attachment in a wall structure and one in the frame pivotably supported panel (2-5). The panel comprises two substantially plate like panel parts (5) attached to a common central member (1), and a device for pivoting the panel (1-5) between open and closed positions. The panel further comprises a top plate (2) and a bottom plate (3), between which the central member (1) and two side members (4) extend. The two panel parts (5) are release ably attached to a respective one of the side members (4), and the top 20 plate (2) and bottom plate (3) are pivotable within limits with respect to a substantially vertical axis in the area of the central member (1), said axis also substantially coinciding with the pivot axis of the panel (1-5) in the frame (20).

Abstract: An arrangement for turning a turret on a ship comprises two slides that can glide along a flange arrangement being arranged on a rim of a turret. The slides are moveable by respective hydraulic cylinders and provide support for a rotatable pawl arrangement which can be rotated into and out of engagement with apertures in the rim. The two hydraulic cylinders are arranged as mirror images of each other in order for the cylinders to push the rim in opposite directions. When the turret is turned, one of the hydraulic cylinders, with the associated slide and pawl arrangement, is used to push the rim in the desired direction, while the other hydraulic cylinder with associated slide and pawl arrangement is utilized to hold the rim in a fixed position while the first slide is pulled back in order for the pawl arrangement to engage with a new aperture in the rim.
