Method for installing heavy-weight foundation for wind turbine, involves partially or completely sinking base part into bottom of sea by fluidizing and suctioning off of bottom by suction and pressure pumps underneath sole of base part

摘要

#CMT# #/CMT# The method involves partially or completely sinking a flat-cylindrical base part (12) into bottom of a sea by fluidizing and suctioning off of the bottom of the sea by suction pumps (26) and pressure pumps underneath a flat sole (16) of the base part. The fluidizing process is exclusively made by pressure lines in a hollow shaft (14) and the sole of the base part. The suctioning off of fluidized bottom is exclusively made by suction lines (28) in the hollow shaft. Sucked off sand is pumped in chambers (20) of the base part and underneath a bulkhead (22) in the hollow shaft. #CMT# : #/CMT# An independent claim is also included for a heavy-weight foundation. #CMT#USE : #/CMT# Method for installing a heavy-weight foundation for an offshore installation i.e. wind turbine (claimed). #CMT#ADVANTAGE : #/CMT# The flat-cylindrical base part is partially or completely sunk into the bottom of the sea by fluidizing and suctioning off of the bottom of the sea by suction and pressure pumps underneath the sole of the base part, where the suctioning off of fluidized bottom is exclusively made by the suction lines in the hollow shaft, thus enabling installation of heavy-weight foundation for an offshore installation in a simple manner while increasing stability of the foundation. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic side sectional view of a heavy-weight foundation. 12 : Flat-cylindrical base part 14 : Hollow shaft 16 : Flat sole 20 : Chambers 22 : Bulkhead 26 : Suction pumps 28 : Suction lines.
