Description
Technical Field
The invention belongs to the technical field of offshore wind power foundations, and particularly relates to a solid ballasting method of a floating wind power platform.
Background
With the continuous development and construction of offshore wind farms, offshore (shore) quality wind resources are becoming smaller and smaller in the areas of available sea. In the open sea area far away from the coast, the wind power resources are very rich, and the development prospect is very wide. However, as the offshore distance increases, the water depth also gradually increases, and when the water depth exceeds 50-60 m, the cost and construction difficulty of the fixed fan foundation fixed on the seabed, which is widely adopted by the offshore wind farm at present, are obviously increased, and the fixed fan foundation is no longer advantageous. Therefore, the offshore floating platform (foundation) is becoming an important research direction for future offshore wind power development.
The main forms of the current mainstream offshore floating platforms are single column, semi-submersible, tension leg and barge. According to the environmental geographic conditions of the sea area of China, the semi-submersible type wind power foundation is the most suitable form of the floating wind power foundation of the sea area of China at present.
The existing semi-submersible type offshore floating platform is mainly in a column-stabilized platform configuration and is in an equilateral triangle layout, and is composed of upright posts, heave plates, lower floating bodies and upper cross braces. The bottom of the upper cross brace is positioned above the wave crest and does not contact the water surface, so that the slamming action of waves is avoided; the lower floating body is positioned below the waterline, the area of the waterline plane is mainly the cross-sectional area of the upright post, and the semi-submersible type design can effectively reduce the platform motion response and load caused by waves. To ensure the stability of the entire offshore floating platform structure, the offshore floating platform needs to reach a certain draft, and then requires larger external ballasts, thus requiring more ballast water tanks and solid ballast tanks to be deployed. However, at present, no precedent for mass pouring of concrete serving as a solid ballast filler exists in China, the grouting weight and the gravity center deviation of the grouting weight are not referenced, the grouting construction quality is difficult to control accurately, the offshore floating platform is inclined to draft, and the stability of the whole offshore floating platform structure is affected.
