RE-ASSESSMENT OF CRITERIA FOR REQUALIFICATION

Although the American Petroleum Institute increased its oceanographic criteria for the design of new offshore platforms in 1993, alternative criteria can still be justified for re-assessment of existing platforms. Issues examined in this paper include: 1) cost- risk optimization of earlier criteria, and its continuing validation by experience; 2) fail-safe-shield-manned (winter storms and sudden hurricanes) and the role of reserve strength and structural redundancy vis-avis inspection strategies; 3) different costs for beefing up a new design, vs. retro-fitting an existing structure in the sea; 4) various methods for initial screening, eg recipe validation vs approximate force comparisons, which are discussed and compared in terms of their advantages and shortcomings.
