1、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
2、 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 int
3、ended 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 th
4、e 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
5、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 standar
