Title: Recent advances in the welding technology on the fabrication of jackup drilling rig

Conference · · Offshore Technol. Conf.; (United States)
OSTI ID:5365035

This paper presents new techniques in the fabrication of rig components that satisfy various requirements for use in cold and/or deep waters such as the North Sea. Details discussed include: improving the toughness of heavy-walled HSLA steel pipes (700-800 MPa class) for the chords and legs of rigs, method of controlling welding deformation in the fabrication of chords, and the effect of post weld heat treatment (PWHT) on the toughness of welded joints. Data are presented from both field operations and laboratory tests of actual size specimens manufactured by industrial processes.
