PURPOSE:To avoid standing in the way of a spud tank by setting high blocks to support the downside of a platform 4 and low blocks to support the downside of the spud tank on the bottom of a dock. CONSTITUTION:High blocks 4 to support the downside of a platform 3A are set on the bottom of a dry dock 2 in such a way as to avoid standing in the way of a spud tank 3B, and low blocks 5 to support the downside of the spud tank 3B are also set. An elevating type offshore working platform 3 whose legs are completely elevated is introduced into the dry dock, and water in the dry dock 2 is discharged to make the downside of the platform 3A contact with the upside of the high blocks 4. The discharge of water is once stopped, the legs of the platform 3A are lowered, the downside of the spud tank 3B is contacted with the upside of the low blocks 5, the water of the dry dock 2 is completely discharged, and the platform 3 is introduced into the dry dock 2. |
