CONSTRUCTING METHOD FOR LIFTING TYPE MARINE WORKING PLATFORM

摘要

PURPOSE:To manufacture a huge platform by utilizing a dock having narrow width by joining platform divided bocies, which are divided into plural number and constructed in the dock, outside the dock through a supporting floating body. CONSTITUTION:The divided bodies 9a, 9b of the platform are constructed in the dock 8, the divided bodies 9a, 9b are pulled out to the outside of the dock 8, and mutually drawn near under floating body conditions, and sections on the water are mutually welded and joined. The semi-dividing type supporting floating bodies 11a, 11b inserted to the lower sections of joined sections and the connecting pieces 14a, 14b of the divided bodies 9a, 9b are connected by wires 15. Legs 2, 2, 2 are dropped on the bottom of the sea from the divided bodies 9a, 9b, the divided bodies 9a, 9b are lifted from the surface of the sea while adjusting the buoyancy of the supporting floating bodies 11a, 11b, and underwater sections lower than the draft of the divided bodies 9a, 9b are mutually welded and joined under this condition.
