Abstract: Anchor assembly for arrangement in seabed comprising a main tube provided with foldable wings movably arranged in recesses of the main tube by being hinged in upper end of the recesses, which wings in initial position is aligned with outer surface of the main tube, where the foldable wings are provided with a centered curved main support element extending in a plane perpendicular to inner surface of the wing and wherein rear part of the main support element is provided with a notch, constriction or recess determining the number of degrees the wing is to exhibit in relation to the main tube in deployed state.

Abstract: A power plant device for the production of energy in the waves by the use of float devices, the motion of which is used to power generator to produce energy, and means of conveyance of energy to further use, the device having a rig that is directed to float in the sea by means of a float supporting construction with the floats in the water line so that these may be affected by wave motion in the sea, and where the floats are arranged in a ring shape around the rig's circumference with spacing between the floats, which floats independently of each other are oriented to engage their respective generators via a transmission system, and the rig is anchored to the seabed via a cable.

Abstract: A method for air-driven propulsion of vessel and a related air-driven vessel wherein the propulsion is provided by air under high pressure being ejected under the sea surface and that air rising again from the sea being captured for providing an air cushion between the hull and the vessel. The vessel can also re-use the air captured for further propulsion. Utilizing captured air for providing an air cushion between the hull and the sea reduces the friction between the hull and the sea.
