PROBLEM TO BE SOLVED: To reduce the additive's resistance of a protrusive construction which is arranged under a draft of floating equipment exhibiting a hull shape, and anchors a riser, a mooring rope or the like.SOLUTION: A riser guide 15 having a large number of guide pipes 16 is arranged under a draft of floating equipment which exhibits a hull shape along a bilge of a side shell. Fore-and-aft cover members 20C as fairings are fixed to fore-and-aft ends of the riser guide 15. Upper cover members 20U and lower cover members 20D are attached so as to cover the guide pipes 16 which vertically extend from a main body of the riser guide 15. After transferring floating-type production/storage/delivery equipment up to an installation sea area, the upper cover members 20U and the lower cover members 20D are removed by underwater work, and riser pipes are attached to the guide pipes 16, respectively.SELECTED DRAWING: Figure 6
【課題】船体形状を呈する浮体設備の喫水下に設けられ、ライザーや係留索などを船体に引きとめるために設けられる突出構造物の付加物抵抗を低減する。【解決手段】船体形状を呈する浮体設備の喫水下において、船側外板のビルジに沿って、多数のガイド管16を備えるライザーガイド15を配置する。ライザーガイド15の前後にフェアリングとしての前後カバー部材20Cを固定的に設ける。ライザーガイド15の本体から上下に突出するガイド管16を覆うように、上部カバー部材20Uと下部カバー部材20Dを取り付ける。浮体式生産貯蔵積出設備を設置海域まで移送後、水中作業により、上部カバー部材20Uと下部カバー部材20Dを取り外し、各ガイド管16にライザー管を装着する。【選択図】図6
