PROCEDE DE FABRICATION D'UN TRONCON D'UNE MEMBRURE D'UNE JAMBE DE SUPPORT D'UNE PLATE-FORME D'EXPLOITATION EN MER |
摘要 |
<p>The invention concerns a method for making a section of a support strut member of an offshore oil-drilling rig comprising steps which consist in: a) machining each longitudinal edge of a semi-cylindrical stiffener ( 13 ) to provide along the longitudinal edge, a lip ( 18 ) for support on a main surface ( 12 A) of a main plate ( 12 ), by producing along the longitudinal edge an outer bevel ( 20 ) on the side opposite the conduit ( 17 ) defined by the stiffener ( 13 ); b) applying a base plate ( 22 ) of the support lip ( 18 ) to weld it with main surface ( 12 A) of the plate ( 12 ); heating the support lip ( 18 ) to weld it with the plate ( 12 ) and constitute a support weld joint; and d) forming a weld bead with filler metal from outside the conduit ( 17 ) in the space delimited between the support weld joint, the outer bevel ( 20 ) and the main surface ( 12 A) of the main plate ( 12 ).</p> |
