Description of the Related Art In the construction of a hull block, particularly in the construction of a hull block in shipbuilding, it is necessary to sequentially mount the hull blocks in a dock or the like and construct the hull while performing welding for construction. The hull blocks are deformed due to their own weight and thermal strain, etc., so even if you try to join a new hull block manufactured as shown in the drawing to a built hull block formed by welding multiple hull blocks, They do not match, resulting in misalignment of the outer plate and aggregate.

Conventionally, as a method of measuring the shape of a built hull block before mounting the next hull block, a weight called a "pron" is attached to a lower end from an end of the built hull. Lower the tension, measure the distance from the tension and the center of the hull directly on the scale, and also measure the vertical height from the end of the pre-built hull block to the bottom of the hull using the scale. The shape of the hull block was measured by checking the horizontality between the starboard side and the port side using a transparent hose called "water filling" filled with water.
