MATERIAL SELECTION, WELDING, AND NONDESTRUCTIVE TESTING GUIDELINES FOR OFFSHORE MOBILE DRILLING UNITS

Offshore mobile drilling units are categorized according to three major areas of relative structural importance: secondary, primary, and special. Guidelines are presented which relate material selection to service temperature and toughness: included are ship steels and quenched and tempered steels for cold weather service. Toughness of electrogas and electroslag weldments are compared with conventional weldments. Comments are presented on the use of partial penetration weldments. The applicability of radiography, ultrasonics, and surface inspection techniques to offshore mobile drilling units, together with possible acceptance criteria are discussed.
