Method for placing gravitu anchor and floating body

Abstract

The present application provides a method for placing a gravity anchor and a floating body. The method includes: fixing a gravity anchor on a floating body when the floating body is located in a dock; sinking the gravity anchor from the floating body to water bottom when the floating body is at a target position. Through the present application, the placement difficulty and cost of the gravity anchor are reduced.

What is claimed is: 
     
         1 . A method for placing a gravity anchor, comprising:
 fixing the gravity anchor on a floating body by changing a water level when the floating body is located in a dock, so that the gravity anchor is located below the floating body and floats with the floating body;   sinking the gravity anchor from the floating body to water bottom when the floating body is at a target position.   
     
     
         2 . The method according to  claim 1 , wherein the fixing the gravity anchor on the floating body by changing the water level comprises:
 draining water away from the dock and arranging the gravity anchor in the dock;   filling the dock with water and making the floating body sail to a position above the gravity anchor;   draining water away from the dock and fixing the gravity anchor on the floating body;   filling the dock with water to make the floating body and the gravity anchor float together.   
     
     
         3 . The method according to  claim 2 , wherein the arranging the gravity anchor in the dock comprises:
 casting concrete in the dock to form at least one concrete block, wherein the at least one concrete block constitutes the gravity anchor.   
     
     
         4 . The method according to  claim 1 , wherein the sinking the gravity anchor from the floating body to the water bottom comprises:
 sinking the gravity anchor from the floating body by a crane.   
     
     
         5 . The method according to  claim 1 , wherein the fixing the gravity anchor on the floating body comprises:
 equipping the floating body and/or the gravity anchor with a buoyancy apparatus, wherein the buoyancy apparatus is detachable and configured to provide buoyancy;   correspondingly, the sinking the gravity anchor from the floating body to the water bottom comprises:   dismantling the buoyancy apparatus.   
     
     
         6 . The method according to  claim 1 , wherein the floating body is an offshore platform. 
     
     
         7 . The method according to  claim 1 , wherein a weight of the gravity anchor is greater than a maximum displacement of the floating body. 
     
     
         8 . A floating body, comprising:
 a main body;   a fixing apparatus arranged on the main body, wherein the fixing apparatus is configured to fix the gravity anchor in such a manner that the gravity anchor is located below the floating body and floats with the floating body.   
     
     
         9 . The floating body according to  claim 8 , wherein the floating body further comprises:
 a crane arranged on the main body, wherein the crane is configured to sink the gravity anchor.   
     
     
         10 . The floating body according to  claim 9 , wherein the floating body further comprises a vertical axis wind turbine.
