Abstract: An anode clamp assembly for attachment to a submerged structure is described. The anode is used for corrosion protection. The assembly comprises an elongate bar shaped or cylindrical anode arranged on a rod having rod ends extending from each end of the anode and clamps being attached to the rod ends. The assembly is easy to use and is suitable for being attached to a submerged structure by means of a Remote Operated Vehicle having a simple construction. Each clamp comprises two first legs having an intermediate bore arranged for rotation around a first rotation axis defined by the rod ends. Each of said first legs at a first end is provided with a griping jaw for attachment to a part connected to the structure and at a second end is hinged connected to a second leg via first hinges having a second rotation axis. The second legs are hinged to each other via a second hinge having a third rotation axis for forming an over-centre acting knee joint together with the two first legs.

Abstract: A system with an underwater vehicle for installation and de-installation of buoys (9) under sea level (6). The vehicle (10) comprises a buoyancy adjustment system (19) for continuously adjusting the buoyancy of the vehicle (10) during underwater operation. A gripper (24) is connected to the vehicle frame (10?) by an orientation adjustment mechanism (29, 30, 31) for adjusting the gripper (24) orientation when installing a buoy (9) onto a flexible underwater line or for deinstalling the buoy (9) therefrom. The vehicle (10) further comprises a controller for manoeuvring and operation.

Abstract: A wave power converter for converting energy from waves including a wave power converter housing with a bottom and a top between which there is a distance limiting structure, and through which there is a central axis, and wherein entirely or partially outside the wave power converter housing there is at least one preferably elongated paddle having a longitudinal direction of a first generatrix and a lower end and an upper end, and which via a first connection to a first power converter with a rotary axis at an angle, preferably at right angles, to the central axis and fastened to the wave power converter housing at the top is provided.

Abstract: Crane arm, preferably to be employed on pillars, comprising a plurality of connecting links, each connecting link exhibiting a predetermined height, preferably being oriented in the direction of the force of gravity, whereby each connecting link in a longitudinal direction, preferably rectangular to the direction of the force of gravity, exhibits a first end portion and a second end portion, and at the first end portion provided with at least one first means for providing a rotary connection with a successive connecting link and at the second end portion provided with at least one second means for the receiving of the first means for providing a (the) rotary connection with the preceding connecting link enabling rotation in a direction around the pillar preferably being oriented rectangular to the direction of the force of gravity.
