[Problem] To provide a method for submerging and guiding structures that can easily and precisely survey, in a short time, the location of a structure or a work fixture that is underwater from a distant operation ship by a wireless method that does not use cables, identify, in real time, the positional relationship between an existing structure and a new structure, and submerge and set a new structure by guiding to a prescribed location. [Solution] Distance data and depth data from measurements, by way of a pair of transponders (T1, T2) disposed on an existing structure or a pair of transponders (T3, T4) disposed on an new structure, of distance and depth between the transponders (T1, T2, T3, T4) is acquired by a computer (PC) by a wireless method; the computer (PC) identifies, in real time, the position of the new structure underwater from the data; and the new structure is submerged and set with a high degree of precision by being guided with respect to the existing structure. |
