10、rewordThis specification is based on the experience acquired during the design,construction,operation and maintenance of offshore processing units and permanent facilities,as supplemented with the experience of operating companies with topsides,fixed platforms,floating structures(e.g.TLPs,spars,and
11、the like),and their tendons and risers.Castings in these applications tend to be limited production components,with relatively few replications,and receive more intense scrutiny than routine mass production runs.Where appropriate,this specification is based on,or reference is made to,international,r
12、egional,national and industry standards.This is a manufacturing specification for the casting itself.It is anticipated that geometric design for both service requirements and casting feasibility will have been agreed collectively between the contractor,manufacturer,and purchaser before this specific
13、ation is invoked.Attendant issues regarding system reliability,geometric design,incorporation into the overall construction,operation,and maintenance are not addressed here.Those electing to use this specification as a reference for their needed level of performance quality should carefully consider
14、 all these attendant issues.When contractors or manufacturers/suppliers use this specification they should be solely responsible for the quality of work and the attainment of the required design and engineering standards.In particular,for those requirements not specifically covered,the purchaser wil
15、l expect them to follow those design and engineering practices which will achieve the same level of integrity as reflected in their best production.If in doubt,the contractor or manufacturer/supplier should,without detracting from his own responsibility,consult the purchaser or its technical advisor
16、.The purchaser may then negotiate with the authorities concerned with the object of obtaining agreement to follow this specification as closely as possible.Nothing contained in any API publication is to be construed as granting any right,by implication or otherwise,for the manufacture,sale,or use of any method,apparatus,or product covered by letters patent.Neither should anything contained in the publication be construed as insuring anyone against liability for infringement of letters patent.Thi
