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.
