Measuring Curved Units

      4/3/1999

DHI recently developed a new three-dimensional program for measuring curved units. The program applies a new measuring concept which not only increases accuracy in constructing units but also improves working conditions. Until now, a balancing weight and a diagonal measurement method were used as the most common methods for measuring the units. Using a balancing weight has yielded results which were low in accuracy. Traditionally, measuring of a diagonal required workers to climb on units 5-7 meters high, thus increasing both the difficulty of measuring mold lines and the risk of serious injury from a fall. The new measuring program developed by DHI has several advantages. First, it does not need to use targets as points of reference on a unit for making measurements. Even though every other known three-dimensional measuring program around the world requires the use of targets, this program requires only collimating with a reference point on the ground. Second, the new method reduces measuring time, since workers can make all the required measurements at once, from one point measuring a curved unit from front to back, side to side, and top to bottom. Third, there is no danger of accidents resulting from a fall while measuring a curved unit. A fourth advantage is the general convenience and simplicity of the measuring procedure. Using an existing light-wave measuring instrument, a worker collimates one measuring point of the unit on the ground and inputs the resulting numerical data into a personal computer. The program installed in the PC then automatically calculates the unit's length, breadth, and height with a high degree of accuracy. The program can be used for various purposes, such as for measuring the units on the bow and stern of ships; chamfering units on four sides in the pre-erection area; and in fabricating steel bridges. Using this measuring program at its work site, DHI workers were able to set units in place easily on the first attempt without the delays which are commonly caused by measuring errors. Most importantly, the program's highly accurate measurements are expected to improve the quality of DHI work. More information: Daewoo Heavy Industries
