PROBLEM TO BE SOLVED: To provide a marine construction system that suppresses increase in ground strength of a floating body structure and enhances construction efficiency on the sea.SOLUTION: A marine construction system is used for constructing a floating body-type marine structure having a floating body structure 1A floating on a sea, and a cylindrical tower part 1B supported on the floating body structure 1A and having a hollow part in a center when seen in a planar view. The floating body-type marine structure includes: a central stage 2 constructed at a central part of the tower part 1B when seen in a planar view, with a stage support post supported on an inner peripheral frame body inside a tower of the tower part 1B, to be lifted/lowered; and an assembly unit 3 rotatable around a tower axis of the central stage 2. The central stage 2 is lowered while the stage support post is fixed on the inner peripheral frame body inside the tower, taking a reactive force on an outer peripheral low-rise part 1D, and the tower part 1B is submerged under the sea through an insertion hole of the floating body structure.SELECTED DRAWING: Figure 1

    【課題】浮体構造物の地盤耐力の増大を抑えることができるうえ、海上での施工効率を向上させることで工期の短縮を図ることができる海上施工システムを提供する。【解決手段】海上に浮かぶ浮体構造物1Aと、浮体構造物1Aに支持され、平面視で中心に中空部を有する筒状のタワー部1Bと、を有する浮体式海洋構造物の構築に用いられ、タワー部1Bの平面視中央部に設けられ、タワー部1Bのタワー内周躯体に対して昇降可能に支持されるステージ支持柱を有する中央ステージ2と、中央ステージ2のタワー軸回りに旋回自在な組立ユニット3と、を備え、ステージ支持柱をタワー内周躯体に固定させた状態で、外周低層部1Dに反力をとって中央ステージ2を降下させ、タワー部1Bを浮体構造物の挿通孔を通して海中に沈める構成とした。【選択図】図1
