Description
Technical Field
The utility model belongs to the technical field of marine body anchor mooring positioning technique and specifically relates to a station is located anchoring system of drowned coral reef marine floating device that says so. The anchoring system is suitable for platforms, artificial floating islands and various offshore floating devices of drowned coral reefs.
Background
The existing anchoring systems of ships, ocean platforms and the like comprise various anchoring systems such as anchoring positioning, single-point mooring, self-elevating platform pile anchoring, semi-submersible platform dynamic positioning and the like, but the anchoring systems are not practical for the station on the drowned coral reef, so that no offshore floating device is arranged on the drowned coral reef world with the water depth of less than-40 meters.
Definition of drowned coral reef: according to the relation between the reef disc and the sea level, the device can be divided into upward reef lifting and submerged reef. The raised reef is also called a raised reef. The drowning reef is characterized in that the reef is sunk because the crust of the earth sinks or the sea surface rises quickly, and the growth of the reef-building coral cannot follow the reef, so that the reef body sinks below the ultimate production depth of the reef-building coral, and the live coral cannot live and becomes the drowning coral reef and then gets deeper and deeper from the sea surface.
The drowning reef is represented by a large ring reef in a sand cluster island in the south sea, and a lot of hidden sand in the sand cluster island is drowning reef.
The reef building speed is inconsistent around the world, the annual growth speed is 0.5-2.8 cm, and when the ground sea level rising speed is more than 3 cm/year, the reef plates firstly become dark sand and finally sink to the seabed.
Many reef discs of the large ring reefs of the medium-sand islands are above the sea surface when the large ring reefs are Zheng and descend in the early period of Ming dynasty, only the walking dark sand in the middle of the large ring reefs is below-20 m below the sea surface until the present day, and the rest of the large ring reefs are sunk below-40 to-60 m to become the dark sand.
For the dark sand below-40 m, the island filling by blowing the sand is impossible, and how to stand on the dark sand is a worldwide problem. A new mooring system must be found which is suitable for dark sands below-40 m.
The characteristics of the dark sand seabed are as follows: the name of the dark sand is that the material is composed of a thin layer of coral and shell scraps on the surface of a coral reef plate instead of sediment. After the general anchor for the ship is thrown down, the claw can not be rotated to form holding power. After the self-elevating platform is inserted into the pile, 3 pile legs bear ten thousand tons of gravity, and the coral reef disc cannot bear the pressure intensity so much that the pile cannot be erected. The dynamic positioning of the semi-submersible platform is too costly to manufacture and use and is also not suitable for standing on dark sand for a long period of time.
