Abstract
PURPOSE: To expose the leg to the atmosphere to carry out maintenance and inspection of the leg in a dry condition by a method wherein the leg located close to the surface of the water of the off shore structure is enclosed by one set of split floating members to remove the water contained in the space between the leg and the split floating members.
CONSTITUTION: In maintainace and inspecition of the splash zone which is exposed alternately to the sea water and the air, the leg 1 located close to the surface of the water of the structure built on the water is enclosed by one set of split floating members 2. A skirt section 4 inclined inwardly is projected to the bottom edge of the floating body 3 of the split floating member 2, fitting the seal material 5 compressed to the external wall of the leg 1 to the point thereof. Next, the water is pumped out from the space developed between the leg 1 and the split floating members 2 with a pump 10a and a hose 10b to expose the splash zone of the leg 1 to the atmosphere. Further, the zone thereof is maintained and inspected in a dry condition.
