On the conversion work of a 29,000 LT DW tank vessel to a 52,000 LT DW one, the old fore body including all cargo tank section and forecastle head were removed, and a new fore body were jointed to old engine room section. At the same time, the old bridge house was removed and shifted from the old body to the new one. The main point of the description in this paper is how to shift the bridge house : the new and old bodies were connected side by side at the level of each main deck by two sets of pin joints and brackets, and at the water level, four wooden fenders were provided to fill up a gap between the bodies. After this preparation, the disconnected bridge house was shifted from the old body to the new one with the aid of a ship launching way, spanning between the ships, with steel ball bearings. During the sliding of the bridge house of 330 tons, enough ballast water was filled in out-side wing cargo tanks of both ships for stationary connection of two bodies under a couple produced by the ballast water.
