To provide an offshore floating body structure with reduced demanded vertical strength, improved propulsion performance and course keeping performance while having high rolling damp effect.SOLUTION: An offshore floating body structure 10 such as FPSO having a hull configuration in a boat-shaped hull form has at least a part of a bow unit 10A and a stern unit 10C composed by an outside plate with three-dimensional bending carried out, and a central unit 10B in between is composed in a parallel unit having right and left broadsides almost in parallel. The central unit 10B occupies approximately 30% to 40% of a total length L of a vessel, for example. Bilge units on both sides of the hull are provided with bilge keels 12 arranged continuously in the longitudinal direction in bilateral symmetry. The bilge keels 12 are provided in a range A extending from the bow unit 10A to the stern unit 10C, and the range A is to be 50% or more and more preferably 60% or more than the total length L.SELECTED DRAWING: Figure 1

    【課題】要求縦強度が低減され、推進性能、保針性能が向上されつつも横揺れ減衰効果の高い洋上浮体構造物を提供する。【解決手段】船体形状が船形の船型を有するFPSOなどの洋上浮体構造物10において、船首部10Aおよび船尾部10Cを少なくとも一部に3次元曲げ加工が行われた外板により構成し、その間の中央部10Bを左右の舷側が略平行な平行部で構成する。中央部10Bは例えば船の全長Lの約30%〜40%を占める。船体両側のビルジ部には、左右対称に長手方向に連続的に配置されるビルジキール12を設ける。ビルジキール12は、船首部10Aから船尾部10Cに亘る範囲Aに設けられ、範囲Aは、船の全長Lの50%以上、より好ましくは60%以上とされる。【選択図】図1
