The invention discloses an FPSO upper module supporting system, and belongs to the technical field of offshore oil engineering facilities, the FPSO upper module supporting system comprises stand columns, one ends of the stand columns are connected with a lower ship body, the ends, away from the lower ship body, of the stand columns are connected with an upper module, and inclined rods are fixedly connected between the adjacent stand columns; the oblique rods bear the load between the upper module and the lower hull in the first direction. The invention further discloses an arrangement method of the FPSO upper module supporting system. The arrangement method comprises the following steps that the positions of the stand columns are planned; the stand columns are fixedly connected with the lower ship body; the stand column is fixedly connected with the inclined rod; and the stand columns are fixedly connected with the upper module. The positions of the supporting stand columns are planned according to the distance between the ship body reinforcing rib positions, the fulcrum positions are increased, the supporting stress of a single stand column is reduced, and the local reinforcing requirements of the ship body and the upper module are reduced, so that the large-scale and standard requirements of the FPSO upper module are met.
本发明公开了一种FPSO上部模块支撑体系,属于海洋石油工程设施技术领域,包括立柱,立柱的一端与下部船体连接,立柱远离下部船体的一端与上部模块连接,相邻立柱之间固定连接有斜向杆,斜向杆承担上部模块与下部船体之间在第一方向上的荷载。本发明还公开了一种FPSO上部模块支撑体系的布置方法,包括以下步骤:规划立柱的位置;将立柱与下部船体固定连接;将立柱与斜向杆固定连接;将立柱与上部模块固定连接。本发明按照船体强肋位间距规划支撑立柱位置,增加了支点位置,降低了单个立柱支撑受力,减少了船体及上部模块局部加强需求,以适应FPSO上部模块大型化及标准化的需求。
