Recommended Practice for the Design of Offshore Facilities Against Fire and Blast LoadingAPI RECOMMENDED PRACTICE 2FB FIRST EDITION,APRIL 2006REAFFIRMED,SEPTEMBER 2020iv SPECIAL NOTES API publications necessarily address problems of a general nature.With respect to particular circumstances,local,state,and federal laws and regulations should be reviewed.Neither API nor any of APIs employees,subcontractors,consultants,committees,or other assignees make any warranty or representation,either express or implied,with respect to the accuracy,completeness,or usefulness of the information contained herein,or assume any liability or responsibility for any use,or the results of such use,of any information or process disclosed in this publication.Neither API nor any of APIs employees,subcontractors,consultants,or other assignees represent that use of this publication would not infringe upon privately owned rights.API publications may be used by anyone desiring to do so.Every effort has been made by the Institute to assure the accuracy and reliability of the data contained in them;however,the Institute makes no representation,warranty,or guarantee in connection with this publication and hereby expressly disclaims any liability or responsibility for loss or damage resulting from its use or for the violation of any authorities having jurisdiction with which this publication may conflict.API publications are published to facilitate the broad availability of proven,sound engineering and operating practices.These publications are not intended to obviate the need for applying sound engineering judgment regarding when and where these publications should be utilized.The formulation and publication of API publications is not intended in any way to inhibit anyone from using any other practices.Any manufacturer marking equipment or materials in conformance with the marking requirements of an API standard is solely responsible for complying with all the applicable requirements of that standard.API does not represent,warrant,or guarantee that such products do in fact conform to the applicable API standard.All rights reserved.No part of this work may be reproduced,stored in a retrieval system,or transmitted by any means,electronic,mechanical,photocopying,recording,or otherwise,without prior written permission from the publisher.Contact the Publisher,API Publishing Services,200 Massachusetts Avenue,NW,Suite 1100,Washington,DC 20001.Copyright 2006 American Petroleum InstitutevFOREWORD This recommended practice is under jurisdiction of the API Subcommittee on Offshore Structures.This Recommended Practice for the Design of Offshore Structures against Fire and Blast Loading is based on sound engineering principles and many years of experience gained by the owners,operators,designers,fabricators,suppliers,and classification/certification agencies of offshore facilities.In no case is any specific recommendation included that could not be accomplished by presently available techniques and equipment.Consideration is given in all cases to the safety of personnel,compliance with existing regulations,and prevention of pollution.This recommended practice has been developed with the help and extensive contributions from industry experts of different areas of expertise.This recommended practice covers both fixed and floating structures that are in use by the industry as offshore oil and gas production systems.These include systems supported by column-stabilized units(semi-submersible vessels),ship-shaped vessels,Tension Leg Platforms(TLP),deep draft caisson vessels(also known as SPARs),and other hull shapes.This recommended practice provides an assessment process for the consideration of fire and blast in the design of offshore structures and includes guidance and examples for setting performance criteria.This document complements the contents of the Section 18 of API RP 2A,21st Edition with more comprehensive guidance in design of both fixed and floating offshore structures against fire and blast loading.Guidance on the implementation of safety and environmental management practices and hazard identification,event definition and risk assessment can be found in API RP 75 51 and the API RP 14 series 52,53.The interface with these documents is identified and emphasized throughout,as structural engineers need to work closely with facilities engineers experienced in performing hazard analysis as described in API RP 14J 52,and with the operators safety management system as described in API RP 75 51.This recommended practice provides general guidelines for incorporating hazard analysis output into the structural response assessment in determining whether the structure or its components meet the specified performance criteria.This recommended practice includes code provisions and associated commentary.The commentary provides design guidelines for the evaluation of structural response to fire and blast loads.Nominal blast load cases are provided for certai
