API BULL 2INT-MET ERTA

Abstract

<strong>Introduction</strong> <br>This interim document presents hurricane-driven metocean conditions (wind, wave, current and surge) for use with and reference by other API standards. These conditions are intended to replace the conditions documented in Sections 2.3.4.c and 17.6.2.a of API RP 2A-WSD, 21st Edition and Appendix C.4 of ISO 19901-1. The metocean conditions documented herein are for guidance and will not generally provide as accurate a result as a dedicated site-specific study. Performance of a site-specific metocean study is the preferred way of ensuring that regional variations in storm climate and local topographic and bathymetric effects are properly accounted for, and that sufficient data is available to properly identify the phasing between wind, wave, current and surge. When performing response-based analyses, a site-specific study must be performed to develop the necessary time histories of metocean parameters. Site-specific studies should be performed within the guidelines included in this document.
