MARINE CONSTRUCTION METHOD FOR FLOATING BODY-TYPE MARINE STRUCTURE, AND FLOATING BODY-TYPE MARINE STRUCTURE
PROBLEM TO BE SOLVED: To provide a floating body-type marine structure and a marine construction method thereof that enhance construction efficiency on a sea and curtail a construction period.SOLUTION: A marine construction method for a floating body-type marine structure includes the following steps: a first step in which a floating body structure 1A is made to float on a sea surface and moored, the floating body structure having an insertion hole formed for installing a tower part 1B by inserting the tower part in a vertical direction; a second step in which work for constructing a frame body of the tower part 1B in the insertion hole at a prescribed height, and work for lowering the constructed tower part 1B under a sea surface, are repeated sequentially for constructing the overall tower part 1B, and submerging the tower part 1B under the sea surface except for a top part; a third step following the second step, in which the constructed tower part 1B is lifted utilizing buoyancy, and the lifting work is halted when a connection part of a ring-form hollow part 1C of the tower part 1B floats above the floating body structure 1A, for constructing the ring-form hollow part 1C on the top part of the floating body structure 1A; and a fourth step in which a remaining part of the tower part 1B is lifted after constructing the overall ring-form hollow part 1C, to have the tower part 1B stand independently on the floating body structure 1A.SELECTED DRAWING: Figure 12
【課題】海上での施工効率を向上させ、工期の短縮を図ることができる浮体式海洋構造物およびその海上構築方法を提供する。【解決手段】タワー部１Ｂを上下方向に挿通可能に配置する挿通孔が形成された浮体構造物１Ａを水面上に浮かべて係留する第１工程と、挿通孔において、タワー部１Ｂにおける所定高さの躯体を施工する作業、および施工したタワー部１Ｂを下降させて海面下に沈める作業を順次繰り返し、タワー部１Ｂの全体を施工し、タワー部１Ｂの上部を残して海面下に沈降させる第２工程と、第２工程の後に、施工済みのタワー部１Ｂを浮力により引き上げ、タワー部１Ｂにおけるリング状空中部１Ｃの接合部分が浮体構造物１Ａ上に浮上した状態で引き上げを停止し、浮体構造物１Ａの上部にリング状空中部１Ｃを施工する第３工程と、リング状空中部１Ｃの全体を施工した後に、残りのタワー部１Ｂを引き上げて浮体構造物１Ａ上に自立させる第４工程とを有する。【選択図】図１２
