Synopsis : Kawasaki Steel's 80 kgf/mm2 high-strength plates are widely used in the fabrication of legs for jack-up rigs to build the lightweight and yet strong offshore structures. This paper introduces various features of Kawasak Steel's plates and other products used for the rigs, including seamless pipes. It also outlines the process of manufacture and fabrication of various components of the legs. Special welding jigs were devised to meet critical design specifications for welded structures, and careful quality control was performed by setting up important check points. |
