The invention discloses a novel process for quickly positioning a component on a drum-shaped FPSO deck. The novel process comprises the following steps: drawing structural characteristics of the deck into a checkered drawing in an equal-proportion scaling manner; when component installation drawings are made in other professions, a square drawing is uniformly used as a base drawing, and the nearest grid line is used as a positioning reference; according to the grid line arrangement diagram of the square drawing, the grid lines of the square drawing are assigned to a deck through black lines; independently naming the grid lines of the grid drawing, independently naming the intersection points of the grid lines according to the names of the two intersected grid lines, and marking the intersection points beside the intersection points; a precision department checks the drawing precision of the grid lines on the deck, and construction can be carried out after the check is qualified; a constructor measures two sizes according to a component installation drawing by taking a grid line as a reference, and then the component can be quickly positioned. According to the invention, the problem that the direction is difficult to distinguish on a circular structure is solved, and the time for a constructor to find an approximate position of a component is greatly shortened.
本发明公开了一种圆桶型FPSO甲板上构件快速定位新工艺,包括以下步骤:将甲板结构特点等比例缩放绘制进方格图纸中;其它专业出构件安装图时统一用方格图纸作为底图并以最近格子线作为定位基准;依据方格图纸的格子线布置图将方格图纸的格子线用黑色线勘划到甲板上;将方格图纸的格子线进行单独命名,格子线的交叉点根据两条相交的格子线的名称进行单独的命名并标注在交点旁边;精度部门对甲板上的格子线画线精度进行检查,检查合格后方可以施工;施工人员依照构件安装图以格子线为基准量取两个尺寸就可以完成对构件快速定位。本发明解决了在圆形结构上辨别方向困难的问题,大大缩短了施工人员找到构件大致位置的时间。
