To provide a riser pipe support structure capable of enduring a great load on an offshore floating body structure.SOLUTION: A riser pipe support structure retains and fixes a multiple number of riser pipes R to a side shell 12 along the longitudinal direction of an offshore floating structure 10. The riser pipe support structure includes: riser pipe fixing tubes 16 for supporting the inserted riser pipe R; fixing tube support structure units 20 for supporting the riser pipe fixing tubes 16; and bracket members 18 for supporting the fixing tube support structure unit 20. Furthermore, side trances 32 are provided at prescribed intervals along the longitudinal direction inside the side shell 12, reinforcement members 36, 44 are provided in parallel to the side trances 32 in between the side trances 32 inside the side shell 12, and the bracket members 18 are attached to the outside of the side shell 12 along the side trances 32.SELECTED DRAWING: Figure 3

    【課題】洋上浮体構造物に大きな荷重に耐え得るライザー管支持構造を提供する。【解決手段】ライザー管支持構造は、洋上浮体構造物10の長手方向に沿って、その船側外板12に多数のライザー管Rを保持・固定する。ライザー管支持構造は、挿通されるライザー管Rを保持・固定するライザー管固定チューブ16と、ライザー管固定チューブ16を支持するための固定チューブ支持構造部20と、固定チューブ支持構造部20を支持するブラケット部材18とを備える。また、船側外板12の内側には、長手方向に沿って所定間隔で設けられるサイドトランス32と、船側外板12の内側のサイドトランス32の間に、サイドトランス32に平行に設けられる補強部材36、44とを備え、ブラケット部材18は、サイドトランス32に沿った船側外板12の外側に取り付けられる。【選択図】図3
