Document Type and Number:
WIPO Patent Application WO/2020/095697
Kind Code:
A1
Abstract:
A part or all of a work ship 1A is lowered using a spud raising and lowering operation for raising and lowering spuds 20A, 20B of a deck raising and lowering system provided to the work ship 1A, whereby an upper structure 41 mounted on the work ship 1A is raised and lowered on a lower structure 42, and the two structures are joined and integrated. It is thereby possible to move the upper structure, which is assembled and integrated on land and conveyed using the work ship, up and down without using suspension equipment such as a large crane, and more quickly than by draft adjustment of the work ship using ballast adjustment, and to join the upper structure to the lower structure disposed in the installation sea region safely and in a short period of time.
