Designation:F 1754 97(Reapproved 2004)An American National StandardStandard Guide forMarine Vessel Structural Inspection Considerations1This standard is issued under the fixed designation F 1754;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon(e)indicates an editorial change since the last revision or reapproval.1.Scope1.1 This guide covers information to develop and imple-ment a marine vessel inspection process.It is intended toprovide considerations for persons interested in planning,organizing,and implementing a structural survey plan for amarine vessel,especially during the design phase of the vessel.It is intended to be used in conjunction with any other requiredinspection or survey requirements but can form the basis forsuch planning in the absence of other such applicable require-ments.1.2 This guide provides owners,operators,shipyards,anddesigners with a plan for developing a detailed inspectionprocess that covers all stages of the operating life of a marinevessel,including the design,construction,and in-service peri-ods.This plan may be developed and used in concert withclassification society and flag state surveys and inspections.1.3 This guide also provides the basis for development of arecommended corrective action plan for typical structuraldeficiencies or deviations,or both.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.1.5 All portions of this guide may not be applicable to allvessels or shipyards since many yard-specific standards toensure contracted level of quality are in existence.2.Referenced Documents2.1 ASTM Standards:2F 1053/F 1053M Guide for Steel Hull Construction Toler-ances Metric33.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 blind spots,nareas of a vessels structure thatcannot be visibly or electronically inspected for failure.3.1.2 large tanks,ntanks of such dimension as to haveuninspectable heights greater than 10 m.3.1.3 telltale areas,nareas of a ships structure identifiedby analyses and investigations during design development asbeing subject to higher stresses or more susceptible to fatiguethan others,even though the higher stresses are still withinallowable limits.Also,areas identified after the vessel is placedin service that continue to experience active or recurringcracking in the watertight envelope or that affect the structuralintegrity of the vessel.4.Introduction4.1 As stated earlier,the intent of this guide is to assist in thepreparation of an inspection plan for a marine vessel during itsdesign,construction,and in-service stages and to plan forinspection during the design.This guide should be used in thepreparation of a specific inspection program for the construc-tion of a specific marine vessel.It is not intended to set anystringent requirements for the structural inspections of anyparticular vessel.The suggestions for various inspection con-siderations in this guide are presented for the purpose ofmaking available for review and use a broad set of guidelines.4.2 This guide is applicable to all commercial and pleasuremarine vessels.Although the references generally apply tosteel and aluminum welded hulls,the overall aspects may beapplied to any material or type of construction.4.3 At any point of its construction or service life,the vesselmay require classification society or flag state regulatoryinspections,or both,as well as shipowners surveys.Thesurveys,depending on occasion,should consider the generalcondition of the vessel,provide a detailed condition assess-ment,obtain data to determine corrosion rate and damage,orobtain information for repair specification development,or acombination thereof.The inspection plan should take intoaccount all of these types of information in its development.On occasions,the surveys also should obtain data on rate ofcoating breakdown.4.4 Because of severe loadings,excessive wastage,poorstructural design,improper use of materials,excessive fatiguecycling,and so forth,failure may occur at any structurecomponent at some stress value that is much less than thetheoretically allowable limit.Therefore,detection of such1This guide is under the jurisdiction of ASTM Committee F25 on Ships andMarine Technology and is the direct responsibility of Subcommittee F25.01 onStructures.Current edition approved May 1,2004.Published May 2004.Originallyapproved in 1996.Last previous edition approved in 1997 as F 1754-97.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summ
