Abstract: Marine structure with one or more suction piles for embedment into the subsea bottom and with buoyancy sufficient such that the structure can be transported over water independently floating, including in an upright position, wherein the buoyancy is concentrated near the suction piles, and may be substantially in line with the suction piles, and wherein the buoyancy is such that if the suction piles touch the subsea bottom with their undersides, at least part of the buoyancy projects above the water surface.
Abstract: A combination of an installation device and a sea bottom anchor is adapted to install the anchor (1) into the subsea bottom by means of suction pressure. The anchor has one or more anchoring amplification members that can be brought into an active position from an inactive position to increase the anchoring capacity of the installed anchor.
