API BULL 2HINS:2009

This document is applicable to permanent fixed and floating structures in the Gulf of Mexico. In this document, inspection refers to structural inspections only and does not include inspections of production equipment, process piping, electrical and instrumentation or other systems and components of the platform, unless noted otherwise. Fixed structures include steel jacket or template platforms, towers and compliant towers, caissons, minimum nonjacket and special structures that are fixed to the seafloor. Design of these structures generally follows API 2A-WSD guidelines. Floating structures include tension leg platforms (TLPs), spars, deep draft caisson vessels, semi-submersibles and any other type of floating or tethered structures. Design of these structures generally follows API 2T, API 2FPS, API 2SK, API 2RD and API 2I guidelines. Post-hurricane structural inspections are not as comprehensive as, or supplant the need for, regular in-service inspections as may be detailed in the structure's in-service inspection plan (ISIP). This document describes post-hurricane structural inspection of structures designed in accordance with the following API documents: - API 2A-LRFD, - API 2A-WSD, - API 2FPS, - API 2I, - API 2RD, - API 2SK, - API 2T, - API 2TD. These structures may also be designed and operated in accordance with regulatory and classification society guidelines and these should be applied as required.
