Abstract

PURPOSE: To ensure safety and facility of work by surrounding a circumference of parts to be repaired with a cylindrical body and by draining water in the cylindrical body by a pump and by performing the repair work for parts to be repaired within the cylindrical body.
CONSTITUTION: Two half cylindrical bodies are combined after surrounding a circumference of parts of legs 1, 1' of an offshore structure to be repaired, with a cylindrical body divided in two semi-cylindrical parts, and by tightening bolts 8. Subsequently, the water in the cylindrical body is drained by a pump, and workers enter inside of the cylindrical body, and perform the repair work of parts of the leg 1, 1' to be repaired properly. And 6 is a part which secures water-tightness, while 9, 10 are packings.
