Definitions
- the invention relates to a suction anchor for the offshore area as a foundation for floating equipment, such as buoys or wind turbines.
- the monopile construction consists of a cylindrical hollow pole.
- the monopile is used in many European offshore wind farms near the coast and is suitable for foundations in water depths up to about 20 meters.
- Monopile designs are not suitable for using more powerful OWEA (6 MW) in deeper water. Their use is economical up to water depths of about 15 meters. Monopiles can be installed easily and quickly. However, heavy piling equipment is needed for the construction.
- the jacket is a truss structure made of steel, which is similar to the construction of conventional electricity pylons. At its four feet, the jacket is anchored with piles in the seabed.
- the jacket construction has already proven itself in the oil industry in deeper water depths. Thanks to the truss structure, 40 to 50% steel can be saved compared to the monopile. A disadvantage of this foundation is the low collision safety.
- the tripod is a tripod construction made of steel pipes that support the main pile under water.
- the tripod is anchored with small piles by ramming in the seabed.
- the tripile consists of three steel pillars that are anchored under water. Over water, a tripod construction is placed on these steel pillars.
- Gravity foundations consist of a large block of concrete supporting the steel construction of the OWEA. Gravity foundations are primarily used in bridge construction and for European offshore wind farms in water depths below 10 meters.
- the floating foundation is a construction in which the floating offshore installations are attached to a foundation on the seabed with a rope.
- the bucket foundation is similarly flushed out of the negative pressure by an inverted bucket and suctions into the sandy ground.
- a floating foundation with improved bracing is described, which is anchored with anchors arranged vertically below junctions of a floating structure. From each anchor, guy ropes extend vertically upwards to corresponding junctions and other guy ropes obliquely upward to beyond junction points.

Monopile können einfach und schnell installiert werden. Jedoch werden für die Errichtung schwere Rammgeräte benötigt.The monopile construction consists of a cylindrical hollow pole. The monopile is used in many European offshore wind farms near the coast and is suitable for foundations in water depths up to about 20 meters. Monopile designs are not suitable for using more powerful OWEA (6 MW) in deeper water. Their use is economical up to water depths of about 15 meters. Monopiles can be installed easily and quickly. However, heavy piling equipment is needed for the construction.
Das Jacket ist eine Fachwerkskonstruktion aus Stahl, die der Konstruktion von üblichen Strommasten gleicht. An seinen vier Füßen wird das Jacket mit Pfählen im Meeresboden verankert.

Am Deckel (5) sind weiterhin ein oder mehrere Druckluftanschlüsse (8) sowie eine Ankeröse (9) befestigt, wobei die Druckluftanschlüsse(8) mit dem Spülluftkranz (12) über Luftleitungen (15) verbunden sind. Die Versorgungseinheit (2) besteht aus einem Gestell (14), das entkoppelbar mit dem zylindrischen Hohlkörper (1) verbunden ist, und einer Saugpumpe (10), die über ein oder mehrere Abreißkupplungen (11) in Form von Quetschventilen mit den verschließbaren Ventilen (7) abreißbar verbunden ist.The suction anchor consists of a cylindrical hollow body (1) and on this cylindrical hollow body (1) decoupled arranged supply unit (2). The cylindrical hollow body (1) can be divided into individual chamber (13). The cylindrical hollow body (1) is designed to be open at the underside (3) facing the seabed, while it is closed at the top (4) by a lid (5). On the open bottom (3), a scavenging air ring (12) is externally welded to the cylindrical hollow body (1). The lid (5) has one or more openings (6) on which one or more closable ball valves (7) are arranged.

Zur Verankerung des Saugankers im Meeresboden wird der zylindrische Hohlkörper (1) mit der daran angekoppelten Versorgungseinheit (2) auf den Meeresboden aufgesetzt. Durch die Saugpumpe (10) wir das Wasser und gegeben falls auch Schlick und Sand aus dem zylindrischen Hohlkörper (1) gesaugt und es entsteht im zylindrischen Hohlkörper (1) eine Vakuum. Durch das Eigengewicht des Saugankers und durch den hydrostatischen Druck sinkt dieser in den Meeresboden und bildet ein Fundament für Offshore- Anlagen. Durch den Spülluftkranz (12) kann der Meeresboden gelockert und das Einsinken des zylindrischen Hohlkörpers (1) erleichtert werden.To anchor the suction anchor in the seabed of the cylindrical hollow body (1) is attached to the coupled thereto supply unit (2) on the seabed. By the suction pump (10) we sucked the water and if given also silt and sand from the cylindrical hollow body (1) and it arises in the cylindrical hollow body (1) a vacuum. Due to the weight of the suction anchor and the hydrostatic pressure, it sinks into the seabed and forms a foundation for offshore installations. By the scavenging air ring (12), the seabed can be loosened and the sinking of the cylindrical hollow body (1) can be facilitated.

Für das Heben des zylindrischen Hohlkörpers (1) als Fundament für eine Offshore-Anlage wird eine Hebevorrichtung mittels einer Kette mit der Ankeröse (9) verbunden und von Meeresgrund an die Oberfläche gehoben. Durch die Druckluftanschlüsse (8) wird Druckluft über die Luftleitungen (15) in den Spülluftkranz (12) gepumpt und auf dieses Weise der zylindrischen Hohlkörper (1) im Meeresgrund gelockert. Außerdem hat der Spülluftkranz (12) auch die Aufgabe, den zylindrischen Hohlkörper (1) mit einem Blasenschleier bei Arbeiten am Sauganker zu umgeben und so eine Schallschutzwirkung zu erzielen.For lifting the cylindrical hollow body (1) as a foundation for an offshore installation, a lifting device is connected by means of a chain to the anchor eye (9) and lifted from the seabed to the surface.
