摘要

Method for positioning one end of a pipe section in relation to one end of a pipe and pipe deposition vessel. The invention refers to a method for positioning a (19) end of the first tub e section (14) in relation to an end (20) a second section of pipe (18),The method comprising: (a) pre -positioning the end (19) of the first tube section (14) near the end (20) of the second tube section (18),Defining a connecting area (51) comprising the respective ends (19, 20) of the first and second tube sections (14, 18);(b) perform a measurement process comprising a plurality of measurement steps, each measurement step comprising: (b 1) move a detection device (86) to a location (89a, 89B, 89C) near the connection area (51);(b2) automatically measure the location (89a, 89B, 89C) of the detection device (86) in relation to the reference site (87);(b3) automatically measure point positions (98a, 98b, 98C, 98D) of points on the ends (19, 20) of the first and second tube sections (14, 18) in relation to the location of the detection device (89a, 89B, 89C);(c) determine a target position of the end (19) of the first tube section (14) in relation to the end (20) of the second tube section (18) based on the measured point positions (98a, 98b, 98C, 98D);And (d) move at least one of the first and second tube sections (14, 18) in order to obtain the target position.
