The present invention is for assembling a rotary sock including a first part rotatably supported on an upper part of a rotary table; a second part connected to the first part; a third part connected to the second part; a fourth part connected to the third part for absorbing energy; and a plurality of bolts and nuts for flange-coupling the first, the second, the third and the fourth part. Provided is the method for assembling the rotary sock for a drill ship comprises steps of preparing for the first, the second, the third and the fourth parts; pre-assembling the first and the second part by flange-coupling the first and the second part by the bolts and the nuts; pre-assembling the third and the fourth part by flange-coupling the third and the fourth part by the bolts and the nuts; and flange-coupling the pre-assembled first and second part with the pre-assembling third and fourth part. The method for assembling the rotary sock for the drill ship can reduce the work period, can reduce working places on a drill floor with relatively many limits such as a narrow working space, and additionally can ease the work and enhance the assembling quality because a locking pin can be correctly inserted by assembling the bolts and the nuts, then forming a locking pin hole, and then inserting the locking pin into the locking pin hole when each part is flange-coupled. [Reference numerals] (S110) Prepare for the first, the second, the third and the fourth parts; (S120) Pre-assemble the first and the second parts; (S130) Pre-assemble the third and the fourth parts; (S140) Flange-couple the pre-assembled first and second parts with the pre-assembling third and fourth parts |
